Can someone please describe the process, in detail, of how you can get a brand new iPhone SE for like $100 from Walmart’s talk plan, but then wait two months so it’s unlocked for your own carrier?

Do you have to sign up with personal info? Or do you just buy the phone and someone at Walmart activates it with a random number?

Why can’t you touch the iPhone for 2 months?

I have so many questions. Please “explain it like I’m 5.”

Thanks in advance!
