I make GSM controlers based on Siemens mobile phones, but I can't read new sms by AT+CMGL=0 only on C45 model ! Why ???

at+cmgl=4
OK
at+cmgl=0
OK

at+cmgr=1
+CMGR: 0,,0

OK

I suppose that problem is memory select, but phone refuse to change to any other memory but SIM. (

at+cpms=?
+CPMS: ("SM"),("SM"),("SM")

OK
at+cpms?
+CPMS: "SM",0,40,"SM",0,40,"SM",0,40

OK
at+cpms="me"
ERROR

AT+CPMS="mt"
ERROR


Any idea ???
