Ok. First off I know the network extender doesn't work with prepaid plan. Here's another scenario. Our son lives in the house with us and has a regular verizon plan with a network extender. So is our prepaid phones not supposed to work with the network extender in the house even though its not with our prepaid plan? if not or maybe not work as well as if we had a regular plan how would this extender of our son's know we are prepaid and not give us as good service or is it built into the prepaid phones? I believe there is a difference so really want to know how this works.
