About this site

Most eSIM sites compare prices. This one starts one step earlier, with the thing that decides whether the phone works at all: what the country's own regulator does to a handset, a call, or a line.

How a rule gets published here

A regulator's own document, or it does not count A law-firm summary, a news report or a competitor's blog is a lead, not a source. Until the text itself is read, the page says so in those words.
Every figure carries the date it was checked Rules change without notice. A number without a date is a number you cannot verify. Current corpus checked 10 Aug 2026.
Negative results are published too Georgia turned out to have no device-registration rule at all; the Philippines' 30-day SIM limit is not in the statute. Those findings are on the site, because 'we looked and found nothing' is an answer people need.
We retract in public Five claims of ours have been withdrawn after re-checking, including one about Thailand's 60-day rule that our own note got backwards. The correction sits in the same place the claim did.

How the site makes money

We sell travel eSIM plans. The profiles come from Airalo's operator catalogue, we buy them at partner price and resell them at our own — the margin is about 57% before payment fees, and it is the same on every country. There is no advertising on the site, no affiliate links to other sellers, and no sponsored placement.

That creates one obvious conflict, so here is the rule we hold ourselves to: a rule page never argues that an eSIM solves a legal problem. Where a country blocks calls over messaging apps, our product does not restore them, and the page says exactly that instead of selling around it.

Who writes it

Pages are published under Editorial team while the site is young. Named bylines arrive with the blog, and only for people who actually carry the expertise the page needs — a name on a page nobody wrote is a trust signal for robots and a lie to readers. How we source, date and dispute numbers is set out in the editorial policy.

The seller behind the checkout is JET SHARING MOBILITY LLC, trading as eSIM energy, registered in the United States. Terms, refunds and the name that appears on your bank statement are on the terms of sale; what we store about you is on privacy.

Nothing here is legal advice. Rules are quoted with their date and their source so you can check them yourself — and where we could not check, the page says that instead.
