If my sim card receive a CMTI for a MMS PUSH, it sends a CMGR and my modem will be unresponsive, and only restart solve this problem. Maybe i should handle differently these messages? What could be the problem?

Found a documentation: https://simcom.ee/documents/SIM900/SIM900_MMS_AT%20Command%20Manual_V1.04.pdf

It includes “MMS PUSH” in “+CMTI: …” when the received short message is a MMS push message. If the current received MMS push message is a concatenated message, it will include“,,” after “MMS PUSH”. is the total number of the parts of the concatenated message and is the index of the current part in the whole concatenated message. For example: +CMTI: "SM",1,"MMS PUSH",2,1. In the URC, 2 means the concatenated push message include two parts and 1 means the current message is the first part.

When all the parts of the concatenated push message have been received, it will prompt “+CMTI: …” URC with “MMS PUSH” and without “,,”.

For example: +CMTI: "SM",1,"MMS PUSH"
