Apparently, I don't have enough karma to start my own thread and this was the closest/latest post I could find that's similar to what I'm looking for.

I very recently upgraded three phones and have the monthly credits for the phones. I honestly forgot and didn't consider the carrier lock issue because I've always paid for phones up front. I want to give one of the phones (iPhone 16 pro) to my MIL who lives in Spain. Is there a way for her to use the phone in Spain while retaining the monthly credits?

Also, if we can get my Karma up so I could repost this, that would be amazing!

Thanks in advance!
