Having received several messages + CMT (about 20-30, not sure) in TE (Terminal Equipment), I get this error: ^SMMEMFULL:"RAM"and will no longer see incoming SMS messages, the same error occurs instead of every SMS message.

Modem configurations below:
> AT&F
> AT+CMGF=1
> AT+CNMI=1,2,0,0,0
After my research on the network, I found and tried the following commands to no avail:
- ATZ
- AT^CURC=0;^PORTSEL=1
- AT+ZRST
- AT+ZSNT=0,0,0
- AT+CNMI=1,2,0,0,1 (last parameter clears the buffer)
- AT+CPMS="ME","ME","ME"\n AT+CMGD=1,4
I also checked this link:
