I am wanting to add a line/phone to the plan but am not sure how it works if I am outside of the US.
Also, my existing line…. Will it remain functional if I never return?

I asked this before and I am hoping things have changed since then.

Mexico has implemented a phone registry system that is tied to biometrics and social security number (equivalent).
We see US Mobile as a work around.
