If I buy the straight talk samsung galaxy 5 from Walmart will it work with the T Mobile network?

I currently have an old samsung galaxy 2 phone and I would like to get a galaxy 5. We have T Mobile as our carrier but I don't like their phone prices is so I'm looking for a cheaper alternative. I don't like the idea of buying a phone off ebay in case it's not compatible or some kind of scam. If I buy the Straight Talk which is 4G LTE at Walmart can I make it work with tmobile and still keep them as my carrier? Thanks.

Check the little map on the package. If it's pink it's a TMobile phone. If not (if it's yellow, blue or red), it's not and it won't.
