Do you have to pay extra on T-mobile to get 4g connection?

I currently have an unlimited plan for $30 3g(at the time I ordered the feature on tmobile data.

No. It's not like Sprint

Doesn't matter if you are or are not using the 4G connection, they won't charge you extra for it.

No, but you do need a compatible phone.
