In my area, I was able to find feature phones that would only do calls and texts. Maybe it just varies by region?
Possible - there are two different families of Tracfones -- the ones with model numbers ending in "C" operate exclusively on the Verizon network and are commonly sold in the Great Plains states.
All models with "C" in the number are normally on T-Mobile/AT&T networks, and are sold everywhere else in the U.S.
