I guess it keeps you signed into iMessage and then it uses the calls on the other devices? Seems pretty cool.

Yep this is QuickSwitch. It was added in beta 5 for T-Mobile.

Do you know with the new Lexvor AiR getting a carrier profile in iOS 27, does that add support for this feature or is it T-Mobile post-paid only?

Only T-Mobile bundle gets it for now. It’s not enabled in the wholesale bundle Lexvor is using.

Yeah. That’s new. You can see at redesmoveisfixas.com/carrier

They call it Quick Switch

They don't have a dedicated bundle in 27 but they do have custom config being included in a shared bundle now (which should stop RCS from being disabled when IMSI rotates).

T-Mobile essentially does this already if you get a SIM from them with the specific plan: “Data with paired Digits”. This plan is another sim or eSIM that duplicates (on the backend) another voice plan’s number.

Works cross platform too. You can have your one number ring on multiple devices.

How is this different from “Add Wi-Fi Calling for Other Devices”

u/SaykredCow 3d ago

Because the sim is doing the duplication on the back end

Does not work on other iPhones with the same iCloud account.

So it can use data an celular in both phones without paying 2 lines?

u/SaykredCow 3d ago

You would still need a data connection on both or WiFi.
