Using At&t V10 on T-Mobile

[sublimegolf]

Is it possible to use At&t's V10 on T-Mobile's LTE network?
I'm interested in getting the blue variant on this phone.
Thanks in advance....

I think so. As long as it's unlocked. Are you planning on buying it at a carrier store?

So I just need to unlock it?
