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 Cellunlocker.net, 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.

You can call 611 and talk to T-Mobile and ask them to unlock your phone since you are going to travel to India and will need to use your phone there.
Simple, legal and easy solution. I have been doing this for the past 9 years with every phone I ever had in my family.
