Can I use the sim card to use in an at&T phone?
I ahve a Motorola phone right now with T-Mobile, but it's dying out on me, and I want to replace just for the next few months. Is it possible to use an at&T blackberry or at&t razor?
Update
How can you tell if the phone is carrier unlocked?
What if it is a samsung phone?
Is dit een goede vraag?
