I'm working with an A06 V2 connected to a Pi zero. Using AT commands to send SMS functions correctly. I try to send MMS using CMMSXXXX commands There is problem. The first commande must by AT+CMMSINIT that return : +cme error 58 and all subsequent commands beginning by CMMS are ignored. Is this module (GSM/GPRS A6) Compatable with CMMS commands? Why CMMSINIT return cme error 58? what means 58 that in not referenced? Thank you for your help.

  • Using AT+CLAC will get the device to output the commands that it understands. Hopefully that output will answer your question.
