We have a registered and active Verizon network extendor, which works fine for our Verizon phones. . We also have users in our house using Tracfone's that run on Verizon's network. Shouldn't the network extnendor work for them as well? Is there something that needs to be done so it would work?
Which model extender do you have? Chances are the signal it is providing is not compatible with what the Tracfone supports.
