I wonder if I buy one for my little sister add the 30 day plan to it then after 30 days put in her regular AT&T sim will that work?
The phone is usable on ATT Postpaid without immediately without unlocking if bought ATT Prepaid. But if you want to unlock in the future, I'm not sure how that is done if you don't use it on prepaid for 6 months. For use on Verizon, for example. The $35 could be treated as just part of the price of the phone.
Tempting as a backup phone except for the 32GB of storage for me. Doesn't seem like the higher storage version is discounted. At least it isn't the 16GB model that was the cheap one a couple years ago.
