Researching Cellular & Wi-Fi Before You Arrive
You've got the gear to connect. You've got the data plans.
But none of those will do you any good if there is no signal to pick up at your next location.
A critical part of successfully navigating a mobile lifestyle and keeping connected is knowing where along your routes you’ll have the best chance of getting online.
For those who rely on mobile internet, it can be very important to have this information before you head out to a new location.
Thankfully, there are tools available to help, whether your goal is to connect via cellular or Wi-Fi.
Doing a bit of research in advance can go a long way to making sure you'll be able to get online once you arrive at your next stop.

Here are some handy resources for tracking this sort of information down:
Check the Carriers Maps
Each of the carriers publishes their coverage maps on their websites - some contain more information than others. Keep in mind, just because a carrier claims to have coverage - it doesn't necessarily mean you'll get it, or that it'll be usable signal.
Many things can impact your signal from the gear you travel with, local terrain, weather, tower congestions and more. Carrier maps don't account for those variables usually, and are derived from computer modeling of the towers they have transmission gear installed on.
And carrier maps can sometimes be a bit.. umm.. optimistic.. for marketing purposes too.
But they're still a good place to start - if your carrier claims to have coverage, it means with the right gear you just might be able to get online.
Here's where each carrier keeps their maps:
Coverage? App
Although we can go to each carrier’s maps online separately, we decided to make it easier by bringing the major carriers’ maps to your smartphone or tablet. Get maps for Verizon, AT&T, T-Mobile, Sprint, US Cellular in the US, and Rogers, Telus and Bell in Canada.
Yep, we wrote an app for that!
Coverage? (available for iOS and Android) allows you to overlay regional or city-level resolution versions of the carriers’ maps so you can create a personalized coverage map for the carriers you travel with and the minimum coverage type (mmWave, 5G Nationwide, LTE, 3G, roaming) you seek.
The maps are stored on device after downloading the app, so you don’t need to have coverage to find out which direction to head when you can’t find a signal.
It’s also useful for planning your next stop to look ahead as to if your carriers claim to have you covered.
But do keep in mind, just because the carrier claims to have coverage (their maps are in part marketing), it doesn't mean you'll necessarily be able to get it. Many thing can impact actual signal like obstacles, distance to the tower, your modem, signal enhancing and tower congestion.
Learn more about Coverage? - or download it from your app store:
Crowdsourced Coverage Maps
There are resources out there that aggregate crowdsourced signal and speed reports and create a coverage map based on what other cellular customers are actually seeing in certain locations.
Crowdsourced apps and websites use actual real-world user signal reports to build a coverage map.
More advanced crowdsourced tools can then use this information to geolocate cell towers and even determine the sectors for individual towers.
These resources rely on user data, so to aid in collecting that data, they often utilize a smartphone app that measures signal on your device and then reports that back to the database.
If you're interested in fleshing out if where you're planning to be will have signal - and what towers are nearby, crowdsourced tools add depth to your intel.
Here are the major (and free!) crowdsourced tools and apps:
- OpenSignal - http://www.opensignal.com
- Has both an iOS and Android app.
- Speedtest Function
- Estimates direction to connected cell tower
- Shows device data usage
- Option to disable automatic submission of signal data.
- Option to contribute signal data in the background.
- RootMetrics - http://www.rootmetrics.com/us/
- Has both an iOS and Android app called ‘CoverageMap’.
- Their coverage map shows general signal quality in 10km (6.2mile) blocks - not as useful for finding coverage at very specific locations.
- Option to contribute signal data in the background.
- Cellmapper - https://www.cellmapper.net/
- Only has an Android App.
- Shows tower location information, tower signal sectors, supporting bands, MIMO, and several other tower characteristics.
- The App map can show which specific tower your device is connected to, assuming the tower is in the database.
- Option to manually upload collected data.
- Displays low-level cellular network information data along with frequency band calculations (for some providers and device dependent).
- The site can be confusing to use, but they do have a beta test with a simpler interface at https://www.cellmapper.net/testmap/.
Of course, with crowdsourcing, the maps are only as useful as the data they collect from users of their apps. These resources tend to have good data for urban areas where they have a strong user base. But, when you get to smaller cities, the maps can show no coverage at all (even when there is coverage!)
For those venturing off the beaten path, it's wise to also supplement crowdsourced maps with the carriers' maps (or, the Coverage? app).
Campground/Marina Reviews
Since so many RVers and boaters depend on a solid internet connection, you’ll frequently find reports of cellular coverage (and Wi-Fi performance) hidden within campground reviews. Here are some of our favorites:
RV & Camping Sites:
- Campendium – This review site includes specific fields for reporting coverage on each of the major carriers in their reviews. Campendium paid supporters can access coverage map overlay for the major cell carriers, and also have the option to filter search results by carrier. All users can filter by whether a park offers free/paid Wi-Fi or not.
- Recreation.gov - The booking platform for federally owned parks, such as National Forest campgrounds and Corps of Engineers parks. There is an area in their review section that shows camper-provided ratings of cell coverage for each carrier, which the service then 'conglomerates' into an overall 'rating'.
- Freecampsites – A database of remote camping and RV boondocking options, and asks reviewers to report their cellular signal for each carrier.
- CampgroundReviews – This is one of the longest-running review sites, and fellow RVers tend to leave coverage reports in their reviews. The Features & Amenities section for each park also indicates which carriers have coverage, and they also have a space to report campground Wi-Fi. Their app allows users to report speed tests.
- RVParky – RVParky.com is a review site where you might find cellular coverage mentions within individual reviews, although they don't yet feature a filter feature for cellular coverage. You can filter by if a park offers free/paid Wi-Fi.
- All Stays - Their app and website also has reviews where past campers may have noted the cellular coverage.
- RV Trip Wizard - Their routing tools include campground reviews with coverage reports, however it is a paid resource.
- The Dyrt - A camping review website with a focus on tent camping, but inclusive of RV parks and campgrounds too. No specific areas to report cellular coverage or experience or search by it, but it might be mentioned in some reviews.
Marina & Anchorages:
- ActiveCaptain - Boaters share their experiences on an app and website, and mentions of internet availability are often included within reviews.
- Waterway Guide - Boaters share their experiences on the website, and mentions of internet availability are sometimes included within reviews.
And of course, don't just read reviews - leave your reviews to help other travelers plan!
Conclusion: Research In Advance
If it's important to you to know where along your route you'll have a good signal, advance planning is important. There are plenty of research tools available to help you, including carrier maps, our Coverage? app, crowdsourced apps, as well as online campground and marina reviews.
But of course the most essential tool in your arsenal is having REDUNDANCY of options to try at each location.
