Are you active on T-Mobile's network with a solid connection?
I specifically ask because iMessage messages go through Apple's servers, so T-Mobile is out of the picture. If you're on WiFi with no T-Mobile connection, it still works. SMS requires a connection to T-Mobile's servers, and if you don't have coverage at your location, you won't be able to receive them.
