If your coverage is good with the carrier you choose in areas where you will mostly be staying, ST is OK
But ST does not offer true roaming, which means if there are no AT&T antennas in a certain area you are visiting, you will get 0 signal.
with AT&T, if you are traveling and there is no AT&T antenna, you will get roaming and your phone will use T-Mo or other local carrier's towers.
This is the major difference between ST and T-Mobile and I would assume same applies to AT&T.. Which is why they let you pick a service.
Correct me, someone, if I am wrong.
I would stay away from ST if you are on the move and need constant service.
Otherwise, I think it is OK in places like NY? Maybe someone in NY can chime in, but at $15 cheaper compared to others, there must be something that's lacking (like no customer service, or in cases they just cut your internet service to EDGE speeds without warning)
They no longer will randomly throttle you. They have updated their terms to allow you 2.5GB of high speed data (LTE+HSPA) and then they will throttle you down to EDGE.
