AT+COPS issue on AT&T provider (U.S.A.) | Thales IoT Developer Community

November 5, 2015 - 10:08am, 1841 views

Hello,

We're on the process to test both the modules PLS8-US and PLS8-X with the starter kit (DSB-Mini & DSB75 adaptor) on the U.S. with the AT&T operator.
We have issues when we send the AT+COPS=0 : it always replies 'ERROR'. And it happens only with AT&T.

The question is : why ?

PLS8-US ATI1 answer :

Cinterion
PLS8-US
REVISION 02.011
A-REVISION 01.010.13

PLS8-X ATI1 answer :

Cinterion
PLS8-X
REVISION 03.005
A-REVISION 01.000.00

Thank you.
