I know many of you were asking me this, “can you use T-Mobile Galaxy S3 on AT&T and as a world phone?”

The answer is yes, once you unlock your T-Mobile Galaxy S3, you can simply change its APN settings to use it on any network you want.   I do recommend trying, you can unlock your phone for around $20-25 within an hour or two.

For AT&T, you will get 3G/HSPA+ for data but not 4G LTE since the T-Mobile Galaxy S3 lacks 4G LTE chips.

For using in other international countries like in Europe and Asia, you should also be able to get full 3G/HSPA+.

In other words, the T-Mobile Galaxy S3 is probably the most versatile Galaxy S3 as it can run on T-Mobile and other world bands while international Galaxy S3 GT-i9300 lacks support for T-Mobile.

Also, FYI, some other phones that support T-Mobile and other world bands include the GSM Galaxy Nexus and GSM HTC Evo 3D.

So, I hope this clears up any questions you might have.
