 at+cmgr=1

"the problem is that when i write at+cmgr=1 it read the first recieved sms if i send a new sms and write at+cmgr=1 it doesn't read the last recieved sms it read the previous"

No, that is not a problem - that is the correct operation!

You need to check the documentation for the AT+CMGR command, and understand what the '1' means in AT+CMGR=1 ...

 RE: at+cmgr=1
