    Anyone know if my sister in law who is here from Germany with her iPhone 6 that says t mobile on it can use a t mobile sim from the U.S. The model number of her phone is MG4J2ZD/A. Would the phone likely be locked?

    Okay...I should add I just put my Att sim in her phone and it worked. So I'm wondering if I should stick with Att or get a t mobile one? She needs to stream some YouTube for her ailing father so we would prefer T mobile for pricing.

    Any help would be greatly appreciated!:)

    If the AT&T SIM worked in her phone, then it is unlocked. She can use either a T-Moble or any other GSM pre-paid SIM while she is here. Probably depends on what provider has the best coverage and price for your area.
