DIAL-UP DATA--------------------------------------------------------------------------------------------------------- TROUBLESHOOTING
General
Most user problems are associated with unfamiliarity or improper use of the Iridium handset or
with improper configuration of software applications. Prior to using Dial-Up Data Service:
• Acquaint yourself and become comfortable with the Iridium voice services and the proper
operation of the Iridium handset. Prior to attempting any data calls, you should be familiar
with the operation of the phone and how to use it to make voice calls.
• Familiarize yourself with the different Iridium data services and products.
• Familiarize yourself with the software applications that you intend to use prior to using them
over Iridium (e.g., Internet browser or Dial-Up networking). If possible, try using your
applications through your ISP via a landline telephone network first.
Cannot register with the Iridium network
•
•
•
•
Is a SIM card inserted into the phone?
Check to see that the antenna is fully attached, fully extended and vertical, and that there is
clear line-of-site to the sky.
Turn the phone off and then on again and wait for the phone to register.
If the phone will not register, attempt to force registration by pressing ↑ 8 on the phone’s
keypad.
Phone is registered, but cannot make a dial-up data connection.
•
•
•
•
•
Verify that the phone is displaying good signal strength.
The SIM card must be provisioned for data. If in doubt, contact your Service Provider.
Check the software version in the phone by pressing *#91# on the keypad. The Motorola
9500 must show software version INC0620 or later. The Motorola 9505 must show software
version LAC109G or later. The Motorola 9520 must show software version RAC0620 or
later. (Newer data-capable versions may be released from time to time, and will be indicated
by a higher numerical sequence.)
Check the cable connections.
Check to see that the dialed phone number is accurate, and that it was dialed in international
format (00 + Country Code + Area Code/Phone Number).
For example, if you are dialing an ISP in Tempe, Arizona, USA, you would enter
00 1 480 555 5555, where 1 is the country code and 480.555.5555 is the ISP’s telephone
number. You can verify that you are dialing the correct number by dialing the number as a
voice call from your Iridium phone. You should hear your ISP’s modem tones if dialed
properly.
•
•
Verify that your settings have not changed (modem properties, phone number, user name,
password, etc.)
Is your Iridium handset dialing? While dialing, the Iridium handset blinks “Data Call in
Progress”. If not, cycle the power on the phone to reset it.
Data call is connected (handset displays a non-blinking “Data Call in
Progress”), but nothing seems to happen.
•
There may be a problem with your networking properties or a problem at the remote end. For
example, if you are using Dial-Up Networking to connect to a LAN or to an ISP, you should
verify that the Networking properties are set in accordance with the requirements of the LAN
or ISP. At this point, you should contact you ISP or remote end administrator.

While connected, the handset seems to stop transferring data.
•
If this happens, terminate the connection, cycle power on your Iridium phone to reset it, and
reinitiate the connection.
Difficulty completing dial-up data calls to some countries
•
You may experience difficulty when placing dial-up data calls to some parts of the world,
including (but not limited to): The Middle East, Southeast Asia, China, India, Russia and
Taiwan.
The end-to-end data call quality and probability of connection is governed by the ability of
modems at the Iridium gateway to synchronize with modems at the termination location.
Modem synchronization is directly impacted by voice compression that is used by
international telephony carriers. International telephony carriers typically compress the
analog speech, and consequently modem tones, to reduce their bandwidth requirements for
carrying calls. This compression can alter the modem tones resulting in reduced connection
speeds, dropped connections, or no connections. PSTN connection quality is not unique to
Iridium data services. The same problem would exist if you made a data call to these
locations from your home computer.
Difficulty maintaining a connection to certain ISPs
•
To improve connection speed and reliability when dialing your ISP, it is recommended that
you choose an ISP access number in the Phoenix, Arizona area if possible (area codes 602,
480 and 623) to reduce the PSTN distance between the Iridium gateway and the ISP
location.
Can place dial-up data calls, but cannot receive dial-up data calls
•
Iridium does not support mobile-terminated dial-up data calls at this time. (Mobile-terminated
dial-up data is the ability to receive a data call on a computer attached to an Iridium phone).
Some web pages take too long to download
This is usually caused by images/graphics on web pages. Downloading images will significantly
degrade your Internet experience due to their size and lack of compressibility. Remember, your
Iridium data connection is not as fast as the landline connections to which you may be
accustomed. Try these tips:
•
Configure your browser to NOT automatically download images, especially since most
images are banners, logos, and advertisements that you probably do not need anyway. See
the Application Notes document for further assistance.
•
Browse the Internet via common, fast-loading web portals such as www.yahoo.com or
www.lycos.com.
How do I check to see that modem properties are set to the correct values
(Windows 95/98/Me/NT)?
The steps to verify your modem properties are the same for Windows 95, Windows 98, Windows
Me and Windows NT. However, some of the windows shown in the following steps may vary
slightly different between the different operating systems.

3. Select the General tab and verify the settings with the below figure. The Port (COM1 in this
case) should identify the port to which you are connecting your Iridium phone via the serial
cable. The Maximum speed should be set to 19200.
4. Select the Connection tab and verify the settings with the below figure. Please note that the
disconnect time of 15 minutes is just a suggestion, and that this will not affect connectivity or
performance. This will disconnect your connection if there is no traffic and is useful if you
forget that you are connected.
