Below is the latest coverage information we could find for each National Carrier.
We also encourage you to check out the latest "Mobile Network Experience" report on OpenSignal.
We also show how many MVNOs each carrier has.
Subscriber counts may include all MVNO Subscribers for each carrier.
Note: Maps are low-res screenshots from carrier websites.
We encourage using the maps/coverage checkers for each carrier.
When it comes to RF signal, lower frequencies are better for range/distance and building penetration.
Higher frequencies may offer better speeds, but are more limited in range and ability to penetrate obstacles such as walls/windows.
