I am looking for mobiles that support AT+CMNI commands to use them as a gsm modem for kannel , because AT+CMNI commands supported mobiles will allow the both MO and MT SMS.
Any suggesting will be welcome , and if there are a way to test if a mobile support AT+CMNI without buying it that will be good.
The AT+CMNI command is standardized in 27.005 and it says
Implementation
Mandatory when any of the new message indications implemented.
so I think you will have a hard time finding a mobile phone that does not support the AT+CMNI command.
