Which Cellular Carrier is Best for RVers, Cruisers, and Frequent Travelers?
Answer: The one that works best at your current location...
Cellular data is probably the easiest and most accessible option for getting online in most places across the USA.
But as simple as it can seem on paper, cellular is also sometimes a confusing subject – primarily because there are just so many options!
You have to choose which carrier(s) you want, which plans make sense, what equipment to purchase, and how much speed and data you actually need.
If you live in one location and only travel occasionally, it’s relatively easy to pick the best cellular carrier.
You can ask your friends and neighbors for experience, check the carrier's coverage maps, and you can check crowdsourced coverage maps like Root Metrics or Open Signal.
While there might be an obvious “best” network for a specific location, frequent travelers have a harder choice to make since... our location changes, often!
There simply is no single network that works best everywhere.
All of the big four nationwide carriers have their strengths and weaknesses in various locations across the country. And each offers different plans & policies that make them more or less suitable as a mobile internet solution depending on your needs.
As a frequent traveler, you need to consider what carrier - or, more than likely, what combination of carriers - will give you coverage and data in the places you want to visit.
This article is an overview of the strengths and weaknesses of the current four major carriers (Verizon, AT&T, T-Mobile, and Sprint) in the US as they relate to mobile internet for RVers, cruisers and frequent travelers seeking an on-the-go home internet replacement.

Video Overview
We created a 17 minute video that overviews the four carriers (updated Sept 2019):
Coverage & Compatibility
All four carriers have embraced the same underlying fourth-generation (4G) cellular network technology, known as LTE - though they use different towers and transmit on different frequency bands resulting in vastly different coverage maps and performance, despite the technological similarities.
The carriers have very different legacy 2G and 3G networks too, which will be phased-out over time.
When comparing carriers - you need to keep coverage maps, compatible devices, supported frequency bands, and expansion plans going forward towards 5G all in mind.
The major difference for each of the carriers is how widespread their coverage is nationwide. And for those relying on mobile internet, 4G & LTE coverage are the most important for the fastest speeds.
In the US, the current four major nationwide carriers are:
- Verizon - Has the most nationwide 4G coverage, and is usually a top pick for travelers.
- AT&T - Close second to Verizon. They are gaining more coverage and spectrum as they implement their FirstNet Band 14 network.
- T-Mobile - The carrier to watch with a rapidly expanding network as they roll out their 600 Mhz network.
- Sprint - Traditionally only useful when close to bigger cities, however roaming agreements with T-Mobile are rapidly improving things.
- On April 1, 2020 - the merger between T-Mobile and Sprint was completed - on paper. Eventually all Sprint customers will become T-mobile customers, and their networks will be merged - but this will be a multi-year process. For now, the two carriers operate independently - and Sprint roams onto T-Mobile as native coverage in a lot of places already.

Cellular Carrier Profiles
A general profile of each of the four major carriers is below.
Verizon
Verizon is the largest cellular carrier in the USA.
It has the widest overall coverage area, the most deployed LTE, and typically good overall performance. If you ask in any RVing or boating group about what is the best carrier, Verizon is the most common answer.
For these reasons, if you’re only going to choose one network – Verizon is the natural top choice.
However, because Verizon’s network is known to have the widest coverage and is the most popular network amongst nomads, it’s not uncommon to find that the local Verizon tower is overloaded and sluggish during peak times, especially in locations that are popular for travelers.
When congested, Verizon can be quite aggressive in its network management slowdowns - and, in practice, Verizon often isn't the best pick in many locations.
Verizon Device Compatibility Tips:
If you want broad compatibility with Verizon's network, seek out devices that support these core LTE bands:
2, 4, 5, 13
And for maximum compatibility and future-proofing, look for support for as many of these additional bands as possible (in rough order of importance):
66, 12, 14, 30, 29, 46
For a deeper understanding of these LTE bands, see our guide to Understanding LTE Modem Specifications.
If you have older Verizon devices without broad support for Verizon's bands, then consider an upgrade, particularly if you notice friends and neighbors are getting better Verizon performance where you are at. New devices with more advanced modems and support for more bands can often run circles around older Verizon devices.
NOTE: Many new Verizon devices are dropping support for Verizon’s legacy 3G network, which should be fully shut down by end of 2020. There are only a few areas left where you will find Verizon 3G and no LTE, so it is no longer worth stressing over remaining backward compatible with 3G.
Recent Verizon News Stories:
AT&T
AT&T is the second-largest carrier and is both a formidable rival and a great complement to Verizon for nomads.
Some even find an AT&T-only solution is feasible now.
AT&T’s LTE network sometimes lags Verizon in coverage, but there are also many parts of the country where AT&T excels - and sometimes it is the only option.
In 2018 AT&T began "climbing every tower" in their network to implement the FirstNet (LTE Band 14) network for first responders.
As this upgrade has spread across the nation, AT&T customers have reported noticeable speed improvements.
We rarely get reports of problems with network management issues on AT&T, despite there being multiple ways to get affordable unlimited data plans on the network.
A combination of Verizon and AT&T on board gives the widest possible coverage across the country.
AT&T Device Compatibility Tips:
If you want broad compatibility with AT&T's network, seek out devices that support these core LTE bands:
2, 4, 5, 12/17
And for maximum compatibility and future proofing, look for support for as many of these additional bands as possible (in rough order of importance):
14, 30, 29, 13, 66, 46
Band 14 (aka FirstNet) support is still rare but is rolling out on newer devices - and though FirstNet is designed to prioritize public safety communications, AT&T automatically allows regular consumers to utilize this long range band at a lower priority for enhanced coverage and speed.
For a deeper understanding of these LTE bands, see our guide to Understanding LTE Modem Specifications.
NOTE: Some older devices may show compatibility for LTE Band 17 instead of 12. Band 17 is an obsolete subset of Band 12, and if a device has Band 12 support explicit Band 17 is not needed.
Recent AT&T News Stories:
T-Mobile
T-Mobile has been the carrier to watch – blowing past Sprint (and now even acquiring them) to take a solid third place in the overall cellular market.
T-Mobile is gunning for Verizon and AT&T next with their merger with Sprint completed in April 2020. The merger gives T-Mobile access to lot of underutilized spectrum across the nation.
For a long time, T-Mobile’s biggest Achilles heel was its lack of raw coverage, particularly in rural areas and indoors - and T-Mobile still falls short of AT&T and Verizon when it comes to coverage. When T-Mobile does have coverage, however, its network speeds are consistently some of the fastest.
T-Mobile has been aggressively filling in the gaps. In 2017 T-Mobile acquired a huge chunk of 600MHz cellular spectrum (LTE Band 71) and has deployed this new band around the country for both 4G LTE and their 5G network. It will continue this nationwide expansion in the years ahead.
But to benefit, you will need a compatible device capable of taking advantage of Band 71.
T-Mobile Device Compatibility Tips:
If you want broad compatibility with T-Mobile's network, seek out devices that support these core LTE bands:
2, 4, 5, 12, 71
LTE Band 71 support is essential for tapping into T-Mobile's longest-range rural coverage, and it will greatly help with reception deep inside buildings as well. For more on understanding the importance of Band 71 support, and compatible devices: An Overview of T-Mobile LTE Band 71.
And for maximum compatibility and future-proofing, look for support for as many of these additional bands as possible (in rough order of importance):
41, 25, 66, 26, 46
For a deeper understanding of these LTE bands, see our guide to Understanding LTE Modem Specifications.
NOTE: T-Mobile customers will want to be able to benefit from Sprint's LTE Bands 25 and 41 in the future. Band 41 will be particularly important - since it compliments T-Mobile's existing spectrum holdings nicely. Band 26 is slated to be sold to Dish Network to become an eventual new carrier.
Recent T-Mobile News Stories:
Sprint
With the merger with T-Mobile now complete on paper, over the coming years Sprint will eventually become part of the new T-Mobile. But for now, the carrier still operates as its own.
Starting in mid-2018 the terms of the (then) proposed merger allow Sprint to have several years of roaming access onto T-Mobile. Sprint customers with compatible devices are already seeing the benefits.
The fourth-largest national cellular carrier has always been a technological oddball - and Sprint’s LTE network uses bands that none of the other carriers have embraced.
Sprint’s biggest advantage is that it tends to have affordable plan options.
But the biggest downside of Sprint for nomads is its limited nationwide coverage map.
The vast bulk of Sprint’s usable fast data coverage is pretty much only found in core urban areas and along major interstates. Outside of that, you’re often roaming with very slow speeds – if you can get online at all.
If you’re planning to stick to urban areas, Sprint might be worthwhile. But for most nomads, Sprint is at best a backup option. However, attractive Sprint based plans should be grandfathered in as eventual T-Mobile plans as the merger is implemented over the coming years.
Sprint Device Compatibility Tips:
If you want broad compatibility with Sprint's network, seek out devices that support these three core LTE bands:
25, 26, 41
Some Sprint devices support a technology called “HPUE” which allows for extended range cellular connections on Sprint’s fastest band, LTE Band 41. HPUE support is still rare but is worth seeking out to get the most out of Sprint’s network.
In the past, only these three bands mattered on Sprint, and many Sprint-branded devices ONLY supported these three. But now that T-Mobile roaming is available, compatibility with T-Mobile bands matters now too.
So for maximum compatibility and future-proofing, look for support for as many of these additional bands as possible (in rough order of importance):
12, 4, 2, 5, 71, 66
For a deeper understanding of these LTE bands, see our guide to Understanding LTE Modem Specifications.

What about 5G?
The 5G world is coming fast - full of both promise, confusion and a lot of boastful claims that will have to be proven out over time in actual practical usage.
The goal of 5G networks is to enable ridiculously fast peak theoretical cellular data rates of over 10 Gbps, with network latency as low as 1ms.
This represents a 50x increase in network throughput and capacity compared to typical 4G/LTE networks – and will truly represent a major generational shift when these technologies are at last deployed.
Most initial 5G deployments in 2018 and 2019 were focused on extremely high-frequency millimeter wave (mmWave) signals - which will only work for a block or two from each transmitter.
This short-range high-speed technology is great for delivering service in places where a lot of people congregate - like stadiums, city centers, and shopping malls.
But 5G technology is not just about short-range mmWave - it will also be deployed on mid-band and low-band spectrum too, delivering lower peak speeds but at a much greater range that will eventually equal what LTE is capable of. T-Mobile is focusing first on deployment over their long range Band n71, and with their new Sprint acquisition they have gained lots of mid-range spectrum with their Band 41 holdings.
It will, however, continue to take time for the carriers to transition from LTE to 5G nationwide.
For nomads who travel outside of urban areas, LTE will remain the core of our cellular connectivity for MANY years to come.
We recommend not focusing on futureproofing for 5G quite yet. The initial products that come out even in 2020 will be first generation - they'll be expensive, clunky and quickly obsolete.

Regional Carriers
In addition to the big four national carriers, there are a number of smaller regional and even local carriers that own and operate their own cellular networks.
Some of the larger examples include U.S. Cellular, C-Spire Wireless, nTelos, Cellcom, and Cellular One.
These smaller regional carriers are usually poor choices for travelers, unless you know that you are primarily going to be spending time in areas where they have a strong native presence.
Even if the regional carrier has nationwide coverage through roaming agreements, if you’re utilizing the service primarily outside its home region, you can find yourself running into all sorts of restrictions and limitations.
And if you are out of your home territory for too long - you will very likely end up getting your account canceled.
Getting Service
You can purchase service directly from each of the carriers as postpaid or prepaid service. Or, there are many resellers & MVNOs (Mobile Virtual Network Operators) who offer plans on the major carrier networks with different features, pricing or restrictions.
