Hi!

I can't find a solution for the following problem:

  • PLS62-W properly registers to the network
  • PLS63-W fails to register with the very same SIM card

Trying to register I get:

ATI
Cinterion
PLS63-W
REVISION 01.202

OK
AT+CMEE=2
OK
AT+CEER=0
OK
AT+COPS=1,2,"26002" 
+CME ERROR: no network service
AT+CEER
+CEER: No cause information available

OK

SMONI status at the time:

AT^SMONI
^SMONI: 3G,10762,491,-4.0,-80,260,01,7D01,C8000F4,32,34,--,LIMSRV

OK

Automatic COPS fails as well:

AT+COPS=0
+CME ERROR: no network service

Manual RAT selection doesn't help, either:

AT+COPS=1,2,"26002",7
+CME ERROR: unknown
AT+CEER
+CEER: No cause information available

OK
AT+COPS=1,2,"26002",7
+CME ERROR: unknown
AT+CEER
+CEER: No cause information available

OK
AT+COPS=1,2,"26002",2 
+CME ERROR: invalid index
AT+COPS=1,2,"26002",2
+CME ERROR: no network service
AT+CEER
+CEER: No cause information available

OK
AT+COPS=1,2,"26002",0
+CME ERROR: unknown
AT+CEER
+CEER: No cause information available

OK

Let me state it again: this very SIM card works perfectly fine using 26002 operator on PLS62-W module.

What is the difference then?
