Tracfone is a service provider, also know as Mobile Virtual Network Operator (MVNO). Tracfone doesn't have its own carrier network, towers, etc. Tracfone buys service from AT&T, T-mobile, and Verizon so Tracfone customers can use them.
If you have a Tracfone CDMA phone, it uses Verizon network. If you have a Tracfone GSM phone, it uses either AT&T or T-mobile, depending on the SIM that is in the phone.
Post the first 6 digits of a SIM card number and we can tell you which network it uses.
