- 2 dead zones mapped (8 km)
Phone signal on the West Highland Way: where it drops
TrailSim estimate for the West Highland Way: 93% of its 153 km has fast 4G/5G data, a further 2% has slow 2G/3G only, and 2 dead zones total 8 km (real cell-tower data, snapshot 2026-09-07).
The stretches below describe the featured plan's networks (GB:3 · GB:EE · GB:O2); the figures above follow the plan you selected.
The signal is strongest between Milton of Buchanan and Tarbet, where the model puts fast 4G/5G data at 100% of the stage.

What you carry with you
The map above shows where the signal holds and where it goes. The report is the version you take with you: on the trail there is no signal, so it is a PDF you keep on your phone or print, plus a GPX track that puts every dead zone on your map app as you walk.
- Every stage of the route with its coverage, kilometre by kilometre
- The strongest network for each stage
- Every dead zone with its coordinates and GPS waypoints
- Printable PDF and a GPX track for your GPS or phone map
Included with every plan, emailed within minutes of purchase.

Frequently asked questions
Is there phone signal on the West Highland Way?
On the networks TrailSim sells for the West Highland Way, 93% of the route's 153 km has fast 4G/5G data and a further 2% has slow 2G/3G only; 2 modelled dead zones totalling 8 km have no signal on its networks. Cell service depends on which networks your eSIM roams on: the plans on TrailSim's West Highland Way page are compared against exactly this route, and every dead zone is named and pinned with GPS coordinates in the coverage report included with each eSIM.
How much data do I need for the West Highland Way?
West Highland Way (WHW) typically takes about 8 days — around 4 GB at 500 MB a day, and the featured plan is picked on exactly that arithmetic. Worldwide, everyday smartphone use averages about 22 GB a month — roughly 730 MB a day — most of it video streaming (Ericsson Mobility Report, Nov 2025). On the trail the picture is lighter: with maps downloaded and video saved for wifi, messaging, photos, weather and bookings run 200–400 MB a day, so we size every recommendation at 500 MB a day for comfortable headroom. Size up if you stream, video-call or share your connection. If you would rather pay only for the days you are out, TrailSim's pay-by-the-day plans for the West Highland Way give a full-speed daily allowance that slows down instead of cutting off, with the number of days set on the payment page.
What is a pay-by-the-day eSIM plan?
A daily allowance of 300 MB to 1.5 GB at full speed, then slower for the rest of that day — never cut off. It is priced per day: you set the number of days (1 to 90) on the payment page, pre-filled with the typical West Highland Way trip length, and the days start on first use. It suits short trips and people who would rather never run out than carry a large fixed plan; the fixed plans on the same page are cheaper per gigabyte for a long trip.
When do the plan days start counting?
On first use — installing the TrailSim eSIM and connecting starts the clock, not the purchase date. You can safely buy weeks before your trip.
Does my phone support eSIM?
Most phones released since 2019 support eSIM, including iPhone XS and later, Google Pixel 3 and later, and most recent Samsung Galaxy models. Your phone must also be carrier-unlocked.
Why not a regular travel eSIM from Airalo or Holafly?
Any eSIM connects to the same physical networks. What TrailSim adds is the route check: it compares real cell-tower data along the West Highland Way itself, picks the network combination that holds best there, and includes the coverage report with every dead zone mapped — so you know before you go where the phone will and won't work. A longer comparison is at trailsim.com/compare/airalo and /compare/holafly.
What if parts of the route have no signal at all?
On most wild routes some stretches have no signal from any network — no eSIM can change that. TrailSim's West Highland Way coverage report marks every dead zone with GPS coordinates and length, so you can download offline maps for those sections and tell people at home when you'll be unreachable. Knowing where it drops is the point.
What if I change my mind after buying?
Uninstalled eSIMs qualify for a full self-service refund within 14 days of purchase — no questions asked. Once the eSIM is installed on a device it can no longer be returned. See the refund policy.
