New to T-mobile and have questions about S3

[nashmarkt]

I used to have GS3 on Sprint network and I switched to T-Mobile and currently using a temporary phone. I like to get a Galaxy S3 (S3 i9300) but when I look at ebay i do not see anyone saying LTE or 4G. Why is that? I thought S3 i9300 is a 4G phone. Am I missing something here?
Basically I like to buy a used phone but I want to have 4G LTE speed.
Your help is very much appreciated.

I believe that phone is the 3G varient of the S3...

Does this mean I have to look for a 4G version of GS3 that works on T-Mobile network?

Yes, I would recommend an unlocked device, but that can cost you...
It's probably cheaper to get it on a contract since it's 0$ now.
