Status of SMS buffer has changed.
Notes:
• Incoming short messages with message class 1 (ME specific short messages) or class 2 (SM specific short messages), see <dcs> in GSM 03.38, will be stored either in “ME” or in “SM” storage. Therefore the “^SMGO:
2” indication could occur, without issuing the indication “^SMGO: 1” before. The indication “^SMGO: 1” means that both buffers (“ME” and “SM”) are full.
• For more information regarding SIM and ME specific message classes refer to <dcs> and the following specifications: GSM 03.38 and 3GPP TS 23.038.
