wife's 14 pro max arrives today, i purchased this phone for her using my apple ID. I've never set up a non IUP iphone before, the ones i've own were all ordered via IUP under my tmobile phone number, so activation was a breeze. since her phone isn't an IUP iphone link to any phone number, how do i active her tmobile esim? i've watched plenty of youtube videos looks like she has 2 options: 1. pairing with her existing iphone near by, and 2. use the Tmoble esim QR code. Since we have 3 phone lines under the same Tmobile account, was there a step during the initial setup process allows her to choose the phone number she's activating? For the Tmobile users out there, which way did you use to activate your esim on iphone 14? any tips? thanks in advance.
