Cricket uses a CDMA network, which is different from Verizon's. However, some Cricket phones are able to use Verizon's LTE network. In order to do this, the phone must have an LTE SIM card and be activated on a Verizon Wireless plan that includes LTE data. If you have a Cricket phone that is compatible with Verizon's LTE network, you can get better coverage and speeds by using Verizon's towers.
