Depends on the SIM you choose. If you have a TMO network phone and select the TMO SIM, you get access to their fast 4G network (not LTE, but as fast as they offer today.)
If you have a ATT network phone and select the ATT SIM, you get access to their 4G network and all related 4G technologies except LTE (for now).
Their data is unlimited, but they will freeze or cancel you if you exceed 2GB per month or suddenly run up hundreds of Mb's in one day. For most people (except those constantly streaming content on their devices or downloading big files), their unlimited plan should work perfectly.
