Straight Talk, a carrier formed from a partnership between Walmart and Tracfone, is now allowing users who bring smartphones capable with AT&T's LTE network to use the 4G data service.
Since Straight Talk is paying AT&T and T-Mobile for their networks, the coverage is the same as if you were paying those operators directly. I havenât seen any coverage differences at all. If you get good coverage now from one of the two carriers, you should get the same with a Straight Talk SIM.
