Sim is detected but not the network

The manual methode:

- Enter ENgineer Mode by writing *#*#3646633#*#* in the Dialing window
- Select CDS Information from the Connectivity tab
- Select Radio Information
- Select the SIM you wish to change the IMEI on
At the AT+ line for SIM 1, enter AT+EGMR=1,7,”THE-FIRST-IMEI-NUMBER”. For SIM 2, enter AT+EGMR=1,10,”THE-SECOND-IMEI-NUMBER”. Of course where the words are, you will enter a number.
NOTE: Do not forget the quotes surrounding the number
NOTE: If you get an error regarding “this command not allowed in user build”, then put a space after AT, so it reads for example AT +EGMR=1,7,”THE-IMEI-NUMBER”
