Net10 is one of a handful of prepaid carriers under the Tracfone umbrella. Like its parent company, Net10 offers pay-as-you-go and monthly plans. It also contracts with each of the four major cell phone carriers, so Net10 customers use the nationwide networks of Sprint, T-Mobile, AT&T or Verizon, depending on their phone and where they live. In some instances, Net10 is a better deal than Tracfone.
