Coverage and Roaming on Verizon MVNOs
Things get a little murkier when it comes to MVNOs that run on Verizon. Some of these smaller carriers may not have full access to the entire Verizon network, so coverage may be a bit spottier in certain areas. However, this mostly applies to very rural regions, so if you're anywhere near people you should be just fine.

In general, do MVNOs have different coverage amongst different MVNOs ?
