EC25-E new carrier connection

Hello,

Is it possible to reset the EC25, so that it can find and connect to a new stronger carrier network?
If yes, how?
Thanks in advance…

Normally using a different carrier’s network means changing the SIM to one from the new carrier.

But if a roaming agreement is in place between relevant carriers for your location, then you can carrier-lock to the preferred MCC and MNC.

As an example, to lock to MCC 505 (Australia) and MNC 01 (Telstra) the command is:

AT+COPS=1,2,"50501"

This command will have the side-effect of setting RAT selection to automatic. Add the RAT (3G=2, 4G=7) to the command if you want active RAT-locking as well. Eg, lock to Telstra 4G/LTE like this:

AT+COPS=1,2,"50501",7
