Force PLMN selection with nRF9151.

[oscargomezf]

Hi,

I would like to know the best method to force a Public Land Mobile Network Identifier (PLMN). When working with an MVNO, it is very common not to get the right timers, T3414 and T3324, and sometimes, you are not able to go to PSM.

From an AT commands point of view, I know you can use the command AT+COPS, but I need to know if there is another proper way to use the Nordic API.

Best regards,

Óscar.

Hello Óscar.

From an AT commands point of view, I know you can use the command AT+COPS, but I need to know if there is another proper way to use the Nordic API.

Yes, correct, you can call the AT+COPS AT command, but it is also possible to set this using our LTE Link Controller and the Kconfig configuration

CONFIG_LTE_LOCK_PLMN and CONFIG_LTE_LOCK_PLMN_STRING.

Kind regards,
Øyvind

Thanks Øyvind.

Is there any way to add this feature at runtime?

Best regards,

Óscar.
