Getting new iPhone and switching carriers - which first?
I'm planning to buy a new iPhone from Apple using a trade-in from my current phone. I'm also planning to switch from a single - user AT&T plan to join my husband's T-Mobile plan.
Should I get the new phone set up with my current AT&T carrier first, and then switch carriers?
Or switch to T-Mobile first, then buy the new phone and have it set up in T-Mobile?
Interested in advantages/disadvantages either way.
