I have Sprint and still on the framily plan if you can believe that. I am thinking about the new SE because its cheap mostly.
For now should I get a Sprint phone or the T-Mobile version and just run it on Sprint? Current coverage here is spotty. If I go to my favorite Taco Bell I get 2 bars of strength but I can't even use the app to order until I drive a block north. I worried about included bands working now and some becoming obsolete in the future.
