Coverage maps: Find a cheap cell phone plan with the best coverage

If you’re planning to switch to a cheaper cell phone plan, you can avoid dropped calls and slow data by finding a wireless provider with great network coverage where you live, work and travel.

The Big 4 wireless networks in the United States are Verizon, AT&T, T-Mobile and Sprint. Which is best for you?

Coverage maps: How to find the best wireless network for you

For 2018, the independent mobile analytics firm RootMetrics by IHS Markit says Verizon’s performance on the national stage remains outstanding, followed closely by AT&T.

RootMetrics reports that third-place T-Mobile performs better in metropolitan markets than at the state or national level.

Smaller carriers called mobile virtual network operators (MVNOs) rely on one or more of the Big 4 networks and provide similar coverage — often at a much cheaper price.

To find the best wireless network for you, follow these three steps:

Review coverage maps: Use the coverage maps for the Big 4 wireless networks as a starting point; see coverage maps for MVNOs on their websites
Confirm coverage: Enter your zip code or address on a carrier’s website to view voice and data coverage
Get recommendations: Ask your family, friends and neighbors about their cell phone coverage; solicit feedback using Facebook or Nextdoor
