Connect to a specific carrier instead of SIM card automatic carrier selection

Hardware MKR Family MKRGSM1400

Hello folks,

I would like to know if it is possible to connect to a specific carrier instead of the SIM cards automatic selected standard carrier.

Reason is: I have a SIM card from thingsmobile.com and it can be used with multiple carriers. The standard selected carrier is O2 and I would like to connect to vodafone because of better reception.

I coudn´t find anything regarding selecting a carrier. There is this "GSM Scan Networks" sketch, but how can I select a different carrier?

BTW: The Arduino MKR GSM 1400 seems to be a great board.

Hi @ATW,

Thanks for the feedback on the board!

The MKRGSM lib currently does not have support for this feature, however I think it would be a valuable enhancement.

Looking at the Section 7.4 of the ublox AT command set, this feature seems possible.

Could you please open an issue on Github to track this enhancement request: Issues · arduino-libraries/MKRGSM · GitHub

Thanks.
