Check the towers where you live
Enter your ZIP code and we show what each network reported to the FCC for your state, side by side, with the carriers and MVNOs that use those towers.
Coverage maps for each host network
Each map is shaded state by state from that network’s own FCC filing. Darker means more of the state’s land area has filed service; unshaded states have no filing published with us.

What speeds these figures represent
The FCC asks each network to map where it can deliver at least a set speed outdoors, with a normal handset. Anything above those floors is not reported, so a network at 99% is not promising fast service everywhere — only service at or above the floor.

The four host networks
Almost every carrier you can buy from runs on one of these, so the cheapest brand often uses exactly the same masts as the most expensive one.

How to check your own address
State-level filings tell you which network is strongest across your state, but they cannot see your street. Check the carrier’s own address-level map before you buy, ask people at the same address which network they use, and prefer an eSIM plan so you can test a carrier for a month without swapping a card.
We never publish a coverage number we cannot trace to the carrier’s own filing or published statement.
