    UPDATE: As pointed out a couple time below, SIM cards from AT&T MVNO's will work in SIM-locked AT&T phones. Sorry for the false information.

    On Friday, I got an AT&T-branded Titan from the Microsoft Store here in Houston. I'm a new AT&T customer and chose the free-with-two-year contract option. Phone was activated and working on the AT&T network before I left the store.

    I was surprised just now when I popped in my H20 Wireless SIM card and it booted up without asking for an unlock code. I used it to make several calls, then switched back to the AT&T SIM without any problems.

    An unexpected bonus! Saves me from paying a few bucks to obtain an unlock code.

    I believe H2O Wireless uses the AT&T Network. Try it with a T-Mobile sim.

    The OP is mistaken & jumped the gun without researching. H2O Wireless is DEF an AT&T MVNO (mobile virtual network operator) & uses their exact same network. And you don't need an unlocked phone to use them. Even the iPhone works with their SIM.
