Will an unlocked bb storm work withh att 3g?


Sep 8, 2009, 8:13 PM
Looking at getting an unlocked blackberry storm and just want to know if the storm will work on att's 3g network. Thanks for any input.

No, it will not work on AT&T's 3G network. It will only do UMTS outside of North America. Be careful. There may be some way besides locks that prevents the GSM portion of the phone from working in the U.S.

My friend uses one on t-mobile. It works just fine.

Your friend uses the 2G bands on t-mobile just fine. Western Hemisphere UMTS/HSPA radio bands are not functional on the Storm. The physical signal demodulator inside the handset will not resonate at the right frequencies to use AT&T 3G service.

I was responding to the other poster stating that their might be other locks on a storm to not allow it on any gsm network in the US...hence my answer.
