I want to get spouse the new iPhone 13 for birthday. Full pay, no trade, no upgrade discounts for this purchase. When I go to check out at Apple.com I can choose ATT (our provider) or no provider. If I select ATT, it asks for wireless number and last four of social. I tried entering my own to see what would happen and it sent a passcode to my phone. I don’t want to do this and spouse get the alert. But entering ATT info does get me a $30 discount (activation for existing customer discount). Hoping one of you guys might know a workaround. Bc these don’t use physical SIMs I’m not sure how I’d do this any other way.

As an aside, if I get a fully paid ATT iPhone, I can unlock after the first month or whatever, right?
