Q: Can the application or terminal I am using directly receive incoming SMS?
A: The received SMS messages are stored in the SIM card memory "SM" by default. The
messages can be read from the SIM card using AT commands, e.g., the +CMGR command.
The +CNMI command (e.g. AT+CNMI=1,2,2,1,0<CR>) allows the application to receive the
incoming SMSs directly in all environments.
The following ETSI specifications can be used as a reference when the GSM 07.05 Text- and PDU
modes are used: GSM 07.05, GSM 03.03, GSM 03.38, GSM 03.40, GSM 03.41, GSM 04.11.
Q: What standards does the Nokia 22 support?
A: There are several standards that have influenced the design of the Nokia 22. From the
application's point of view, the most important standards are those that specify the AT-command
interface: ITU-T V.25ter, ETS GSM 07.07, ETS GSM 07.05, TIA-578-A, TIA-592 and TIA SP-2388.
