New Hampshire is one of the most geographically diverse states in the country, home to forests, mountains, lakes, ponds, and even 18 miles of coastline.
These geographic features can present problems when trying to get cell phone service, since signals work best when they can travel from a tower to your phone relatively unimpeded. Despite this, however, there are enough towers in New Hampshire that it’s home to generally good coverage from the three major carriers (Verizon, AT&T, T-Mobile).
In this article, we’ll tell you which carriers offer the best coverage in New Hampshire, and show you how to use our interactive maps to check service in your specific area of the state. Read on to learn about the best coverage in New Hampshire.
Verizon wields the best 4G coverage in New Hampshire. The carrier’s 5G network, meanwhile, is a bit more limited in terms of its overall reach in the state.
Verizon’s 4G network covers 77% of New Hampshire’s 9,304 square miles, a truly impressive stat when you consider how much of the state is rural. This makes going with Verizon a smart move if you live in New Hampshire.
Verizon’s statewide 5G network reach is fairly limited in New Hampshire, covering just 8% of the state. That said, the carrier is actively expanding its network reach in the state, so you can expect this percentage—and the availability of the carrier’s fastest network speeds—to increase in the coming weeks and months.
AT&T’s 4G network offers an impressive amount of coverage in New Hampshire (76%); its 5G network, however, is fairly limited, covering 12% of the state.
AT&T’s 4G network covers 76% of New Hampshire’s 9,304 square miles, including many of its rural, untamed areas throughout the northern reaches of the state. We recommend using the map above to verify coverage in your specific area.
Like Verizon, AT&T’s 5G network offers far less reach in New Hampshire than its 4G network, covering just 12% of the state. Thankfully, this percentage is sure to increase as the carrier continues to build out 5G nodes in the region. It should also be noted that much of AT&T’s current 5G coverage is made up of the carrier’s so-called 5G+ spectrum, which delivers super-fast speeds, low latency times, and enhanced reliability.
T-Mobile delivers the most 5G coverage, and the third-most 4G coverage, in New Hampshire.
T-Mobile’s 4G network spans 56% of the state of New Hampshire, which is less than both Verizon and AT&T. That said, your town or region may very well be covered by T-Mobile—use the map above to find out.
T-Mobile wields the best 5G network in New Hampshire, covering an impressive 41% of the state. What’s more, a good portion of this 5G coverage is made up of the carrier’s 5G Ultra Capacity network, which delivers incredibly fast speeds for latency-free browsing, streaming, and gaming.
Verizon, AT&T, and T-Mobile aren't the only big carriers in New Hampshire. UScellular also maintains a presence in the state, operating its own 4G and 5G networks. The company's 4G network covers 15% of the New Hampshire, while its 5G network covers 11%.
While we’ve outlined cell phone coverage from the three major U.S. cell phone carriers, it’s important to know that you aren’t limited to these companies if you need cell phone service in New Hampshire. A variety of smaller carriers, or MVNOs, also operate in the state, allowing you to sign up for equivalent plans, with similar coverage, for less than you’d otherwise pay.
All of these carriers lease from the aforementioned major carrier networks to provide coverage to their customers. If you’re signed up with Spectrum Mobile, for example, you’ll have access to Verizon coverage, since the carrier runs on that network. Here are some popular MVNOs, and the networks they operate on:
When it comes to cell phone coverage, you don’t just need a cellular signal—you need that signal to provide adequate speed. That’s why it’s important to distinguish between 4G and 5G coverage in your area. In general, 5G provides faster speeds and greater reliability than 4G. However, that’s not always the case, as there may be instances when the speeds of these respective coverage types are actually quite similar.
There’s more to getting the best coverage than just signing up with the carrier that offers reliable service in the places you spend time. These include:
Verizon delivers the most 4G LTE coverage in New Hampshire (77%), while T-Mobile offers the most 5G coverage (41%).
To determine the best cell phone service in your area of New Hampshire, we recommend taking a look at our 4G and 5G coverage maps and zooming in to inspect your local area.
Yes, Verizon not only covers New Hampshire, but wields the best (in a tie with AT&T) 4G service in the state, covering 46% of its —- miles.
