Introduction
Welcome to the world of wireless connectivity and thank you for choosing
Cingular as your service provider. Within this User Guide, you will find
the information that you need to connect to your Email, the Internet, and
even your corporate intranet using the Cingular Communication Manager
software.
Communication Manager 5.1 serves as an upgrade not only to earlier
versions of Cingular Communication Manager, but also to Cingular's
legacy Connection Manager software. Previous users of either package will
find much that is familiar in this new client software, as well as many new
and exciting features.
1
Communication Manager Overview
Cingular Communication Manager simplifies access to Cingular's wireless
data network – integrating access to both high-speed WiFi and nationwide
GSM - into a single, easy-to-use software package. With Cingular
Communication Manager, there are no confusing configuration options
and no complex network jargon. We have designed this for you and hope
that you enjoy your experience.
Cingular Communication Manager is more than just a data connectivity
tool. It also integrates with your existing VPN software, allows you to send
and receive Text Messages and even provides you the ability to create
custom connection profiles.
Plus, you can easily switch between the GSM Connection and WiFi
Connection windows using the large tabs near the top of the screen.

Cingular Communication Manager Help
How the Cingular Communication Manager Works
Cingular Communication Manager is pre-configured to prefer WiFi Profiles
over GSM (EDGE, GPRS, UMTS, CSD) Profiles to ensure that you get the
best available Cingular connection for your particular location. This means
that:
• When a WiFi network (which has been saved as a profile by you or by
Cingular) becomes available, Cingular Communication Manager will
take action based on the connection settings in the WiFi profile.
• When a WiFi network (which has been saved as a profile by you or by
Cingular) is not available, Cingular Communication Manager will
search for an available GSM network. Once an available GSM network
is detected, Cingular Communication Manager will take action based
on the connection settings in the GSM profile.
When connected to a GSM network and a Wi-Fi profile network is detected,
Cingular Communication Manager will take action based upon the
connection settings in the WiFi profile. If you choose to change the
connection to the WiFi network, the GSM connection will be terminated
when the connection to the Wi-Fi network is complete. If your WiFi profile
is set to auto launch your VPN, it will re-establish your VPN session once
the WiFi connection is active.

Post-Install Configuration
This page includes options that configure the initial operation of Cingular
Communication Manager. They include:
• Default for WiFi Management
• Install /Configure Tethered Device
• Use VPN Integration
Note that the settings for all of these options can be changed later.
Default for WiFi Management
Check this box if you want Communication Manager to be able to connect
to Wi-Fi networks. This will enable the display of the Wi-Fi user interface.
When this box is not checked, the display of W-Fi related screens and
controls will be suppressed.
Notes
• Wi-Fi management must be enabled if you wish to access to the
Cingular Wireless Hotspot Service.
• If Wi-Fi management is enabled on a Windows XP system,
Communication Manager will shut down the "zero config" Wi-Fi
management tool built into Windows each time it starts (this tool may
7
Cingular Communication Manager Help
conflict with Communication Manager's Wi-Fi management
capabilities). The tool will be restarted automatically when you exit
Communication Manager.
• If you wish to change this setting later, it can be found in the
Application tab of the Settings window.
Install /Configure Tethered Device
If this box is checked, Communication Manager will launch the Device
Wizard to install the appropriate drivers for your cellular device as soon as
you exit this screen. If you do not wish to install device drivers at this time,
you may remove the check from the box. If you wish to install drivers later,
you can launch the Device Wizard at any time by selecting Device Wizard
from the Tools menu.
Use VPN Integration
If this box not checked, the Do Not Use VPN option in the VPN settings
window will be selected when you first launch the Communication
Manager software. This has the effect of disabling the VPN functionality of
Communication Manager until you configure the VPN tab of the settings
window. Checking the box has one of two effects:
• If you are upgrading from a previous version of either Cingular
Communication Manager or Cingular Connection Manager for which
you have configured VPN settings, Communication Manager will
retain the previously-configured settings.
• If you do not have previously-configured VPN settings, the Use
Existing VPN Profile option will be selected in the VPN tab of the
settings window. However, you may not be able to successfully
establish a VPN connection until you complete the configuration for
that option.

Note: If you see a *closed* item in the networks list, this indicates the
presence of one or more Closed networks. Connecting to such a
network requires the creation of a profile for that network. See How to
access a closed network for more information.
6. If the network is encrypted, you will now be prompted to enter an
encryption key. If this is the case and you know the required encryption
key, enter it and click OK. If you don't know the encryption key for an
encrypted network, you must click Cancel and select a different
network. See How to access an encrypted network for more information
on connecting to encrypted networks.
7. Once you have completed this procedure, the Cingular Communication
Manager software will attempt to establish a connection to the selected
network.
You can also configure the Cingular Communication Manager to
automatically connect to certain networks whenever they are
available. See Network Profiles for more information.
Detecting and Connecting to Preferred Wi-Fi Networks

Wired Equivalent Privacy (WEP)
Unlike a wired local network, a wireless network cannot easily be protected
from potential intruders by physical barriers such as walls. Since radio
signals travel through physical objects, a potential intruder merely needs to
listen with the right equipment to see the traffic traveling across a wireless
network. For this reason, public wireless networks typically employ
encryption to protect their users.
WEP is the standard encryption technology that is used on most WiFi
networks today. However, a more advanced, more secure encryption
technology called WPA is beginning to gain acceptance and is replacing
WEP on an increasing number number of networks.
WiFi Protected Access (WPA)
WiFi Protected Access (WPA) is a key improvement to WiFi data security
for both Enterprises and SOHO users. Providing a secure alternative to the
flawed WEP encryption standard, WPA is a specification created by the
WiFi Alliance designed to simplify and improve the process of securing
WiFi networks. WPA provides an upgrade path for enterprises which
allows them to preserve existing investments in 802.1x/EAP authentication
capabilities which may have been deployed as initial access control
methods. In addition SOHO users can take advantage of a Pre-shared Key
mode in WPA which allows the encryption and network protection
capabilities to function on a home network as well.
What types of WPA are there?
There are two types of WPA (Communication Manager supports both):
• WPA
This type of WPA uses 802.1x to authenticate a user to a network. This
type of WPA is typically used in office and enterprise environments.
You will need to check with your IT staff to see if you can utilize this
form of WPA.
• WPA-PSK
WPA-PSK (Pre-Shared Key) is typically used in home/small office
environments. The encryption key is between eight and sixty-four
characters. Currently, several 802.11g access points and routers support
(or have updates for) WPA-PSK. Refer to your access point/router
manual to see if you can use WPA-PSK with it.
15
Cingular Communication Manager Help
What else do I need to use WPA?
To utilize WPA, you will need a WPA-compliant card and access to a WPAenabled network.
Using WPA with Communication Manager
Networks that are encrypted with WPA will be noted on the network list.
The type of encryption (WPA, WPA-PSK, etc) will also be noted. For WPA
encrypted networks, you will also need to utilize an 802.1x Authentication
mode to access the network, for a Public Shared Key (PSK) encrypted
network, you will have to enter an encryption key as you would for a WEP
encrypted network.
To learn how to connect to a WPA-enabled network, see How to Access an
Encrypted Network

Enabling 802.1X Authentication
What is a closed network?
Closed networks are private networks that do not choose to broadcast their
existence. Such a network will not appear in the list of available networks
unless it is specifically configured as a Network Profile. Cingular
Communication Manager can detect when there are closed networks
present simply because it "sees" unidentified broadcasts in the WiFi
frequency band. When this happens, it will display the word *closed* in the
WiFi networks list.
However, Communication Manager cannot detect the actual name of or
establish a connection to a closed network unless you create a profile for
that network. For more information, see the following:
• How to access a closed network
• How to create a WiFi Network Profile
16
Connecting to WiFi Networks
How to access a closed network
To access a closed network in the Cingular Communication Manager, you
must set up a Profile for that network. Follow these steps to create a closed
Network Profile:
1. Open the Cingular Communication Manager. You will see the main
window.
2. Select Edit Connection Profiles from the Connections menu. The
Network Profiles window will now be displayed.
3. Select the WiFi heading in the left pane of the network profiles
window.
4. Click the Add button. The first page of properties for the new profile
appears.
5. Enter the name of the network you want to add in the SSID field. Be
aware that the network name is case sensitive and must be entered
exactly as provided by the administrator of the closed network to which
you want to connect.
6. Check the This is a non-broadcasted network (closed) box to identify
this as a closed network.
17
Cingular Communication Manager Help
7. Fill out the remaining fields on this window as instructed by the
administrator of the closed network.
8. Click Next to continue to the next page of profile properties.
What is an encryption key?
An encryption key is a code key used to encrypt data exchanged between
an encrypted network and the Cingular Communication Manager. You
cannot exchange data with an encrypted network without having the
appropriate encryption key.
There are two ways to obtain an encryption key:
• Obtain a key from the administrator of the network you are trying to
access.
• Configure 802.1x authentication according to the instructions of the
network's administrator. A key will be provided automatically as part
of the login process.

Secure WiFi Connections
Encrypted WiFi networks are typically deployed by corporations or other
entities that need to provide secure wireless access restricted only to their
specific user community.
There are numerous standards available to protect the WiFi airlink (from
WiFi modem to WiFi access point), such as WEP and 802.1X. Which one of
these you need to use is determined by the network administrator who has
configured the wireless network infrastructure. Cingular Communication
Manager software must be configured to match the type of encryption
deployed in the WiFi network you are connecting to.
Customers whose connection also traverse the Internet (ex. public WiFi
hotspot) may also consider protecting the Internet transport with end-toend encryption, such as a VPN. The sections under the Securing a WiFi
Connection heading address the airlink security of the WiFi connection. For
additional information of VPN security, see Virtual Private Networks.

How to access an encrypted network
The steps required to connect to an encrypted WiFi network are the same
as those required to connect to a non-encrypted WiFi network — until you
click Connect. When you click the Connect button, the client will display
the following window:
In order to proceed, you must do one of the following:
• Enter a network encryption key obtained from the administrator of the
network you are trying to access.

802.1x Authentication
IEEE 802.1x is an authentication standard that greatly reduces the security
vulnerabilities associated with connections to IEEE 802.11 wireless
networks. The IEEE 802.11 wireless network standards specify two
authentication methods: one that is based on identification of the wireless
adapter (open system authentication) and the other that is based on a proof
of knowledge of a secret key (shared key authentication). 802.1x enforces
the authentication of the credentials of a wireless computer or user before
allowing access to the wireless network and, depending on the actual
authentication method used, determines encryption keys for wireless
communication. If you connect to an 802.11 wireless local area network
(WLAN) without 802.1x authentication enabled, the data that you send is
more vulnerable to attacks.

Once a GSM/CSD profile has been created, to chose Circuit Data for your
connection, just toggle between connection types using the Select GSM
Connection Profile section of the Connections menu.
For more information on creating and using network profiles, please see
Network Profiles.
Using the correct GSM Profile
Communication Manager comes pre-configured with several profiles that
should be used depending on how your device was provisioned. Each
profile defines different connection methods to the network based on the
Access Point Name (APN) your SIM has been provisioned to use.
The APN specifies the external networks that a mobile device can access. It
also defines the type of IP address to be utilized, security mechanisms to
invoke, available value added services, redundancy, and fixed end
connections.
Each pre-defined profile in Communication Manager is designed to
connect using an APN to the Cingular network. A brief summary of the
APN profiles is listed below. Depending on the service to which you have
subscribed, you will have one of the following groups of profiles available
to you:
Group 1
• EDGE/GPRS Accelerated: This is the standard profile for users with
profile group 1. In most cases, it will provide the best experience. This
profile can be used to connect to EDGE, GPRS and UMTS networks.
Additionally, data acceleration will be inherent in some connections
established with this profile. Data acceleration can be configured on the
Acceleration tab of the Settings window.
• EDGE/GPRS Non-Accelerated: This is similar to the accelerated profile.
However, data acceleration will not be used.
Group 2
• GSM Connect — Proxy: This is the default APN/profile provisioned for
most users with profile group 2. Proxy APN provides a Cingular
private IP address and does not allow unrequested data to pass from
the Internet to the mobile user.
• GSM Connect — Public: Provides a public IP address and does not
allow unrequested data to pass from the Internet to the mobile
user. Additional charges may apply.
50
Connecting to GSM Networks
• GSM Connect — Internet: Provides an Cingular private IP address and
does allow unrequested data to pass from the Internet to the mobile

Accelerated Profiles
Accelerated connections utilize in-network acceleration/compression
technology to provide a faster connection experience.
Data acceleration can result in reduced graphics quality. If you are
using your accelerated profile and wish to reload a given web page
with full quality graphics, do the following:
•
Microsoft Internet Explorer users can press CTRL + F5 (or
hold CTRL while clicking the RELOAD button on the
browser).
•
Netscape users can press SHIFT + Reload.
If you experience difficulty with your connection while using an
accelerated profile, disconnect and try connecting with the
unaccelerated profile.
For more information on connection profiles, please see Network Profiles.
About GSM signal strength
The signal strength of a GSM network is expressed in the main GSM user
interface as both a series of bars and as a numerical value (in dBm). A lower
numerical value means “better signal”. For example:
• -60 dBm is an exceptionally strong signal
• -70 dBm is quite good
• -80 dBm is satisfactory
• -90 dBm is a weaker signal with reduced throughput
• -100 dBm is a borderline unusable signal level
• -113 dBm indicates a "no signal" condition
Cellular data is a line of sight technology. Obstructions between the cell
tower and you “attenuate”, or weaken, the signal strength. Often signal
strength can be improved by moving slightly, approaching the windows of
a building, or laying the antenna down flat away from the laptop LCD.
51
Cingular Communication Manager Help
If you are moving while connected, your wireless connection may drop if
signal is lost (approaching -110 dBm). Prior to losing signal your wireless
device should start to scan for a stronger signal from a roaming provider in
order to improve the performance of the connection. If your device
automatically switches to a roaming provider, the data session will be lost
for a short interval. Disconnects will likely result in interruption of
application functionality and data transfers that are underway. Critical
work that cannot be interrupted should not be performed while moving in
order to minimize this risk.
Note: Signal strength is not the only variable factor in determining the
throughput of your wireless connection. Distance from cell site, network
availability and traffic, device, applications, tasks, file size, transmission
limitations and interference, and other factors also impact the speed of your
connection.
GSM Network Types: GPRS, EDGE, UMTS
Cingular offers GPRS, EDGE and UMTS services.
GPRS (General Packet Radio Service) is an IP-based service for GSM
cellular networks, and has been deployed worldwide. GPRS/EDGE
supports IP-based applications and provides a mobile extension of the
Internet, or private intranets. More information on GPRS can be found at
http://www.cingular.com/midtolarge/gsm_gprs
EDGE (Enhanced Data Rates for Global Evolution) is a powerful
enhancement to the radio technology used by GPRS. EDGE dramatically
improves national wide area wireless data throughput rates and network
capacity, while providing full backward compatibility for GPRS devices
and applications. More information on EDGE can be found at
http://www.cingular.com/midtolarge/edge
The Cingular UMTS network offers wireless mobility at broadband speeds.
UMTS is currently available in six metro markets: San Francisco, Seattle,
Phoenix, Dallas, San Diego and Detroit. For more information and the latest

GSM Security
Cingular maintains a comprehensive security policy that dictates the
requirements and procedures to help maintain the security of Cingular
networks. Any network security architecture must take into account endto-end communications, as well as all the individual links and nodes that
make up the network. The primary security components of an application
that uses the Cingular GSM network are:
User Authentication
A device can be configured so that a user is prompted to enter a personal
identification number (PIN) before being able to use the device.
Network access authentication
The network authenticates a user device against information stored in the
SIM.
Encryption
The radio link is protected by further encrypting information between the
mobile device and the infrastructure node called the Serving GPRS Node
(SGSN).
Protection of IP addresses
IP addresses are encrypted, never transmitted in the clear.

Virtual Private Networks (VPNs)
Virtual Private Networks (VPN’s) are end-to-end, secure, private networks
that can be accessed over a public backbone network (like the Internet)
without compromising their privacy. Typically, they maintain their privacy
by forming secure (encrypted) "tunnels" directly to the users who access
them.
Cingular Communication Manager software automatically recognizes
supported VPN client software and associated profiles. Once a supported
client is installed, all you need to do is choose the existing VPN software
and profile (or designate another VPN software to use) from the VPN
settings window.
Note: Enterprises often use some sort of VPN to provide remote access to
their corporate network. If you receive Cingular wireless services through
an enterprise (such as a place of employment), the network administrator
for that enterprise may actually require you to establish a VPN connection
whenever you use your wireless service. If this is the case and you fail to
establish a VPN connection within a set period of time after you establish a
wireless connection, you will be disconnected with an error indicating that
VPN access is required. For more information, contact your enterprise
network administrator.
Configuring a VPN Connection
Follow these steps to configure a VPN connection:
1. Consult the administrator of the VPN you wish to access. The
administrator will provide you with VPN client software and
instructions for establishing VPN connections using that software.
2. If the VPN client software is not already installed on your system,

Network Profiles
Network Profiles are networks that you have saved at connection time
using the auto-connect options or have manually added to the Network
Profiles network list. Additionally, Cingular has created some pre-defined
profiles for you.
Creating Network Profiles has the following advantages:
• You can configure the client to automatically connect to a Network
Profile whenever that network is available.
• If the last network you connected to is not available at a particular
location, the Cingular Communication Manager will display a network
from your list of network profiles in the main window (if one is
available). This allows the same easy, one click connecting to an
alternate network.
Moreover, you must have a profile for the following:
• You cannot connect to a closed WiFi network or unless you create a
"closed network" Network Profile.
• You must have a GSM network profile for each GSM network that you
wish to connect to.

Note: Modifying RWIN values is an advanced networking task. If you
have any questions about RWIN please contact your IT systems

administrator.
RWIN
Other computers sending data to your system expect your system to
acknowledge each packet of data it receives. This helps to ensure that your
system actually receives all the data it requests.
The TCP Receive Window (also known as RWIN) specifies the maximum
amount of data that another system may send before it receives an
acknowledgement for at least some of the data sent previously. When this
value is set too high, the sending system may transmit far more
information than your current Internet connection can actually receive in a
given period of time. This could result in lost information that the sender
has to retransmit (causing delays). If the value is set too low, the sender is
spending more time waiting for your system's acknowledgements than it
needs to and less time sending information to you (this can also cause
delays).
Since the optimal value for RWIN varies depending on the speed of the
network to which your system is connected, the value can be set
independently for most types of connections. When you install a new
network adapter (or wireless modem), the installer program will usually
optimize the RWIN value for its type of connection. So, for the vast
majority of connection types, you never need to worry about this value.
However, your PC also has a Global RWIN value that may be used in
certain circumstances, the most common being when you establish a VPN
connection (depending on the specific VPN make). The RWIN settings
provided on the Advanced Networking settings tab adjust this global
value. However, you should only adjust them if you are specifically
instructed to do so by your network administrator.
Use custom value
Selecting this option allows you to specify a custom global RWIN value in
the space provided.
Optimized GPRS/EDGE value
Selecting this option sets the global RWIN value to an optimized value
specified by Cingular (if any).
91

Selecting this option keeps the global RWIN value at its default setting for
your operating system. It is strongly recommended that this option is
selected unless you are specifically instructed to do otherwise by your
network administrator.

Cingular Communication Manager is not saving my username and
password
One of the requirements of the Cingular Communication Manager
application is 128-bit encryption. This encryption is the highest available
for Internet communications, and is the standard for most secure
transactions occurring on the Internet today. On most Operating Systems,
128-bit encryption is ensured if Internet Explorer version 5.5 or higher is
installed. On Windows 2000, the requirement is the installation of either the
Windows 2000 High Encryption Pack or Windows 2000 Service Pack 2 (see
www.microsoft.com for information on how to download these upgrades).
Without 128-bit encryption, some features of the application may not work
as expected.

caused by transient issues such as poor quality of the wireless signal or a
temporary service outage.
Try connecting again. In many cases, you will be able to connect again
immediately. If that doesn't work, restart Windows and try again.
Also, check the signal strength gauge in the main window. If the signal
strength is low, you may need to try a different connection technology or
wait until you are in an area where you can get a better signal.
If you have good signal quality and trying again does not work, there is
most likely some sort of temporary service outage.

Text Errors and Messages
Acquiring Data Service
This appears in the status area of the main window when Communication
Manager is attempting to establish a connection to a GPRS/EDGE network
or a UMTS network. The message is typically displayed while the
connection is in the "GPRS attach" phase ("PDP attach" on UMTS
networks), which essentially means that the network has been successfully
detected and your wireless device is now attempting to register with the
data network and get authenticated.
If this message remains displayed for an extended period, it probably
means that your device is having difficulty getting attached. There are a
number of possible reasons for this, including the following:
• This may be due to poor signal strength. Check the signal strength
gauge in the main window. If the signal strength is too low, you may
have to choose a different access technology or wait until you are in an
area with a stronger signal.
• If you have not yet used this SIM to connect, the Subscriber Identity
Module (SIM) in your GPRS device may not be properly provisioned
for data access. Contact Cingular Customer Care for additional support.
(if you have connected using this SIM, it is probably provisioned
correctly).
• The network detected may not actually be available. For example, there
may be some sort of temporary service outage or if you are roaming,
you may not actually have permission to connect to the roaming
network.
No SIM
This message indicates that your wireless device requires a SIM (Subscriber
Identity Module) to establish a wireless connection, but the SIM has not
been properly inserted. See Inserting your SIM card for more information.
Note: SIMs not provided with your device or from other service providers
may not be recognized.

Cingular Communication Manager Help
No Wireless Device
This message usually indicates that your wireless device is not currently
connected to your PC or is not switched on. In the case of cell phones and
cellular modems, it may also mean that Communication Manager has not
yet been configured to use the device. Do the following:
• Make sure that the device has been properly connected to your PC.
Also try disconnecting the device and then reconnecting the device to
your PC.
• Make sure that the device is receiving power. Battery powered devices
should have batteries. Rechargeable devices should be charged. AC
powered devices should be plugged into a suitable outlet.
• For GSM devices, make sure the correct device is selected on the GSM
tab of the settings window.
• If you have not yet configured Communication Manager to use this
device, run the Device Wizard to do so. See Using the Device Wizard
for more information.
For advanced users only
• If all of the above steps fail to resolve the problem, it is possible that the
driver for the device is corrupt. See Reinstalling the Device for
information in reinstalling your device drivers.
Searching For Network
This appears in the status area of the main window when Communication
Manager is searching for any type of wireless network to connect to.
Ordinarily, this message should disappear within thirty to forty seconds.
For 3G capable devices, searching could take up to 2 minutes. If the
message persists for longer, Communication Manager is having difficulty
finding an available network. There are several reasons this may occur.
• You are out of coverage area. Check the signal strength indicator to see
if it displays more than 1 bar of coverage.
• If this is the first time the device or SIM module has been used it may
take up to 4 minutes to recognize and attach to the appropriate
network.
• You may be using the wrong connection profile. Choose an alternate
connection profile from the Select GSM Connection Profile section of
the Connections menu and then try to connect again.

Troubleshooting Guide
Application Launch Issues
Application is not visible after launch
Cingular Communication Manager is designed to launch into the display
state from which it was last exited. As such, it is possible that the Client
will launch directly to its minimized state, causing the user to assume that
it is not actually running.
Resolution: Look in the system tray for the signal icon. If that icon is
present, double clicking it will display the main Communication Manager
user interface. In addition, a right click on the signal icon in the system tray
will raise a menu. The show item in this menu will have the same effect as
the double click.
Auto launching of Communication Manager at Startup
The Cingular Communication Manager installation can be setup to allow
the Communication Manager to automatically launch when a computer
boots up or when a new user logs into the machine. This may (or may not)
be the desired functionality for the end user.
Resolution: The user can change this behavior of Cingular Communication
Manager by selecting Tools>Settings and choosing the Advanced Settings
tab. Select Auto start check (or uncheck) the box to automatically launch
Cingular Communication Manager.
PC Card Issues
In some circumstances, Cingular Communication Manager will not be able
to detect a user's wireless card that is installed in the system. The following
is a list of possible causes of this situation:
Card Driver and/or firmware are outdated
Communication Manager is an application that takes advantage of the
latest capabilities of EDGE/GPRS certified hardware. As such, a card may
not function properly and may not be detected if recent firmware and
drivers have not been installed on a user's computer.
Resolution: You must re-install the device: See Re-Installing the Device.

IrDA or Blue Tooth Connections
Blue-tooth is a technology that allows communication between digital
devices such as PCs, mobile phones, lap-tops and Personal Digital
Assistants (PDA). It is achieved by a short-range (around 10 meters)
wireless connection that will vary in form depending on what hardware it
is to be associated with:
I launch the Cingular Communication Manager using a Blue Tooth phone.
Communication Manager states "No Wireless Device"
• Make sure the phone is turned on and within 10 meters of the
computer.
• Make sure the phone is paired to the computer.
Pairing allows you to avoid entering access information each time a
connection is attempted. Paired devices share a unique Link Key, which
they exchange each time they connect.
If your phone is IrDA capable make sure the infrared port is pointed in a
direct line of site of the infrared port on the phone. Make sure the phone is
powered on and properly charged.

Network Scanning Issues
Cingular Communication Manager never finds available network
The EDGE/GPRS Cingular Communication Manager does not report
available networks. The EDGE/GPRS Communication Manager does not
indicate EDGE/GPRS support.
Resolution: In the above conditions either the SIM does not have data
capabilities or no wireless data network is available. Verify with the
provider that Data capabilities are enabled for your SIM.
Cingular Communication Manager indicates CSD (Circuit Switched Data) not
EDGE/GPRS
The Cingular Communication Manager indicates that only CSD is available
when you expect EDGE/GPRS data capabilities.
• Verify with your provider that either circuit switched data or packet
data is configured for your SIM.
• Verify that Data connectivity is configured for your SIM.
• Verify the Connection profile is set appropriately for EDGE/GPRS
EDGE/GPRS Cingular Communication Manager says "Ready to Connect", but
fails to connect
The EDGE/GPRS Cingular Communication Manager allows a connection if
the EDGE/GPRS device has associated to the EDGE/GPRS network. If the
GPRS signal strength is to low the client will fail to connect and display
“Ready to Connect” again.
