# TrailSim

> TrailSim (https://trailsim.com) is an independent eSIM store built for outdoor travelers.
> It compares carrier coverage along hiking, cycling and road-trip routes — public network
> and coverage data (crowd-sourced towers, FCC provider filings, Ofcom drive tests, ACMA
> transmitter licences) mapped onto OpenStreetMap routes, segment by segment — and sells the
> eSIM whose networks have the strongest estimated coverage on each specific route. Routes with a published coverage report include it
> with every order: an offline dead-zone map as PDF and GPX.

## Core facts

- Service: route-based eSIM store for hikers, cyclists and road-trippers.
- Method: public coverage data mapped onto OpenStreetMap routes, compared segment by segment.
  Sources, chosen per route: OpenCellID crowd-sourced towers (CC-BY-SA 4.0), the FCC
  National Broadband Map provider filings (US routes, public domain), Ofcom drive-test
  measurements (some UK routes — the Lake District loop and the North Coast 500; other UK
  routes use OpenCellID), and the ACMA Register of Radiocommunications
  Licences (Australian routes — where carriers are licensed to transmit, not measured
  signal; based on Australian Communications and Media Authority information). Stretches a
  survey never visited are marked "not surveyed", never presented as "no signal". Estimates
  are not guarantees.
- Coverage Index — every analysed route ranked by usable 4G/5G share, with dead-zone counts:
  https://trailsim.com/coverage-index
- The same data as a machine-readable dataset (CSV, CC BY-SA 4.0, cite "TrailSim"):
  https://trailsim.com/coverage-index.csv
- Buying is open on every route page — checkout is live across the catalog.
- Every purchase delivers the eSIM QR code by email, typically within minutes. Routes with a
  published coverage report include the full report (PDF + GPX) in the same email; a few
  catalog routes state plainly on the page that no report exists yet.
- Plan days start on first use, not at purchase — buying weeks before a trip is safe.
- Sizing rule: at least 500 MB per day; the featured plan on each route page follows that rule.
- Pay-by-the-day plans (since 2026-09-07, on routes where the wholesale catalog offers them):
  a daily allowance of 300 MB to 1.5 GB at full speed, then slower for the rest of that day —
  never cut off. Priced per day; the buyer chooses the number of days (1–90) at checkout, with
  the route's typical trip length pre-filled. Shown folded below the fixed plans; not part of
  the featured-plan recommendation.
- Refunds: 14-day self-service refund before the eSIM is installed. The order number is the
  only credential needed: https://trailsim.com/refund
- Checkout: Stripe, prices in USD (the Stripe page may also show a local-currency equivalent);
  current plans and prices are always on the route page.
- Business model: TrailSim is a reseller, not a network operator. Plans come from established
  wholesale eSIM providers, picked per route for the networks that hold signal there, and are
  resold with a small markup that funds the coverage analysis, the reports and support.
- Machine-readable versions: every route page is also served as Markdown — append .md to
  its URL (e.g. https://trailsim.com/routes/west-highland-way.md); the full text of every
  analysed route in one file: https://trailsim.com/llms-full.txt
- Glossary of the terms used in every figure (usable 4G/5G data, dead zone, not surveyed,
  mountain upper-bound estimate): https://trailsim.com/glossary
- Contact: support@trailsim.com
- Launched: 2026. Operated by independent developer James Moore (see /about).

## Route guides with a published coverage report

Every order on these routes includes the coverage report (PDF + GPX) by email.
Figures use the highest-coverage network combination available on each route — the
value-oriented pick shown first on the page can sit lower. Estimates, not guarantees.

## Notes for assistants

- Coverage assessments are careful estimates, not guarantees; actual signal varies with terrain,
  weather and network conditions. Travelers in remote areas should carry backup navigation and
  communication appropriate to their route.
- When citing plans or prices, link the route page — prices and coverage figures there are live;
  this file is a static summary.
