Check the towers where you live

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.
