What we do not do
We do not publish affiliate rankings, scores, fake reviews, time-pressure messages or universal coverage claims. Where provider terms are relevant, we direct readers to the original source and note that they can change.
What a traveller can do now
Write down the route, check the present plan, label device lines, save the next two map areas and decide what should still work when a live connection does not.
