Evidence before promises.
Public-source compilation
We use publicly accessible plan terms, official documentation and relevant research. Each source is linked in the guide with a check date. We preserve source evidence privately; readers can inspect the original link.
Keep the layers separate
A retail eSIM brand is not necessarily the visited mobile network. Operator-declared coverage, crowdsourced measurements and a traveller’s experience answer different questions. Our map is geographic context only: no measured speeds, no fabricated coverage footprint, and no no-signal inference from missing observations.
Terms outrank a convenient scenario
Confirm the exact plan’s permitted use, hotspot rights, fair-use policy, activation rules and validity. A work scenario is not a promise that a Tourist SIM permits commercial or router use. Travel connectivity guidance is not immigration advice.
Photographs and commercial links
Local images carry source and licence attribution. A scenery photograph does not prove reception. External editorial links are protected with nofollow, noopener and noreferrer. A paid or affiliate relationship would be explicitly labelled; no affiliate programme membership is implied.
Calculator and map limits
The calculator multiplies your editable daily usage assumptions by days and group size, then adds your chosen buffer. It is a planning estimate, not a plan recommendation or speed guarantee. Location markers represent sourced island reference points, not buildings or network measurements.
