Add failback to higher priority PLMN

We use a multi-carrier sim that has the ability to attach to more then one carrier.

It’s great that we can now set a priority list of plmn’s and the logic handles failing over to the next one if needed.

However we don’t currently have an option to failback to the top plmn carrier after an idle period of time.

This is implemented for the sim cards, but not for plmns

Something like this mockup


@sitloongs can you ask engineering to review?


I am in the same boat.

As one example, AT&T SIMs, when roaming, typically have access to multiple carriers outside US.

So being able to run through PLMNs in this priority manner would be very useful.

Engineering team is considering the feasibility. I will update again if get the latest news from Engineering team.
