pinky 0 Posted November 12, 2008 · Report post Aloha B) Don't know if this has been asked yet and this is my first post so please bear with me. I just ordered my HTC Touch Pro w/ a data plan only on AT&T but currently have T-mobile as my voice & data carrier. I live in Hawaii where T-mobile has not yet rolled out their 3G network, but AT&T has. My question is whether I would be able to use my T-mobile voice plan and AT&T's data plan on a single unlocked Touch Pro? Does AT&T require a SIM card for their data plan only accounts? If yes, then I'm assuming the answer is NO since T-mobile requires a SIM for their phones. Any answer/advice is greatly appreciated. Mahalo! Share this post Link to post Share on other sites
