Will a T-Mobile Galaxy S3 work on the Roger's phone network

[chrono_patrick]

Hi,
From what I understand smart phones purchased from T-Mobile can connect on Roger's and AT&T, but they can't get 3G connections. Is this true for the Galaxy S3? Are there any other Android phones that would work on both networks?

Thanks!

As far as I know all T-mobile devices will work on AT&T. But there is a catch. The phones have to be unlocked. The only issue will be internet speed. T-Mobile and AT&T have different frequencies for their 3G/4G networks, so you will be stuck with EDGE data speeds. Otherwise they work completely fine.

S3 from T-Mobile (SGH-T999) does have frequencies for 3G/HSPA+ used by Rogers, Bell, Telus and AT&T. It will work if unlocked.

Another phone that can work on T-Mobile and others is Galaxy Nexus.
