MC52iR3: network registration not working | Thales IoT Developer Community

July 11, 2018 - 6:59pm, 1451 views

Hello,

we've a problem with Cinterion MC52iR3 modules: network registration seems not to be working.

We've already checked different SIM cards from different operators without success.

AT+CREG?

+CREG: 0,2

If we select the operator manually, we get this:

AT+COPS=1,2,26203

+CME ERROR: phone busy

If the module is powered on, we get this:

^SYSSTART
+CIEV: mcclock,1

ATI

Cinterion
MC52iR3
REVISION 01.301

AT+CPIN?

+CPIN: READY

AT+COPS=?

+COPS: (1,"E-Plus",,"26203"),(1,"Telekom.de",,"26201"),(1,"Vodafone.de",,"26202"),,(0-4),(0,2)

AT+COPS?

+COPS: 0
