Best Cell Phone Coverage in Idaho

22 September 2017

Unspoiled, rugged. Awe-inspiring. These are just a few of the words you’ll hear used to describe Idaho’s landscape.   

Much of the state is made up of soaring peaks, raging rivers and placid mountain lakes. The biggest city is Boise, with a population of only 650,000, and some lesser ones include Idaho Falls and Coeur d’Alene, which wouldn't even register as notable cities in some states. All of which is to say: Idaho is country.   

Given the predominance of rural land, you wouldn’t expect the state to be exactly blanketed with cellular network coverage. Thus, it’s unsurprising that the state’s overall coverage score comes in at a fairly weak 41%.   

Read on to learn more about which carriers provide the best cell phone coverage in Idaho, and where. That way, you can know before you go. After all, there’s nothing worse than being shut out of service on your way to go fly fishing on the Salmon, skiing on Baldy, or hunting in the Pioneers.  

Coverage in Idaho At-a-Glance

Just like Idaho's landscape, coverage in the state has its ups and downs. Overall it's pretty good though, considering how much of the state consists of remote wilderness. Idaho earns a coverage score of 41 out of 100. Here's a full list of coverage ratings by state

What we love
  • Coverage from AT&T the best
  • Coverage from Verizon and T-Mobile not terrible
What could be improved
  • Sprint coverage not so hot
  • Coverage always a bit tricky in deep valleys or remote natural areas

All four major carriers are well represented throughout the state, as are a multitude of smaller MVNOs that run on their networks. 

AT&T has the widest network reach in Idaho, and takes the title for the best network in the state. 

Verizon comes in second, and T-Mobile is in third. Sprint's coverage lags a bit, but customers can connect to other networks where Sprint has roaming agreements.

Idaho is broadly covered by both 3G and 4G LTE technology. 3G is the network that some older phones run on, and the one newer 4G LTE-capable devices fall back to when unable to reach a primary network. is broadly covered by both 3G and 4G LTE technology. 3G is the network that some older phones run on, and the one newer 4G LTE-capable devices fall back to when unable to reach a primary network.

Big Carriers vs. Small Carriers in Idaho

Did you know that there are dozens of small carriers that run on the major networks, but charge a fraction of the price for service? These companies are known as Mobile Virtual Network Operators, MVNOs for short. MVNOs purchase network service from the major providers at wholesale prices, then pass the savings on to consumers. 

If you're interested in Verizon's coverage, for example, but are looking for a better deal, Straight Talk Wireless, Twigby and Red Pocket are just a few of the smaller providers you'll want to check out.
