The thing is that TFW is not identical to Verizon or AT&T; they operate on their own towers. When you see TFW carrier or ask, “What does TFW mean?”, it means your phone gets service through TracFone. Yet, TracFone in its turn also resorts to the resources of larger organizations such as Verizon, AT&T, or T-Mobile. This implies that the quality of your connections could still be good, depending on the network that TracFone gives you.
