How we research
and check what we publish
We publish under the company name rather than invented personal bylines. This page explains what stands behind that name, so you can judge the guides on something more useful than a stock photo and a job title.
Who writes these guides
The Viasimo editorial team. We publish under the company name rather than invented personal bylines, because the guides are written and revised by whoever on the team knows the subject, and a fake individual byline would tell you less about their reliability, not more. Where a guide draws on something we can actually verify — our own network data, our support queue, a published operator source — the guide says so in the text.
How we check coverage and network claims
Operator names and radio technology on destination pages come from the network data our suppliers publish for each market, not from marketing copy. Where a country's host network is 4G-only or 3G-only, the page says that plainly instead of listing 5G as a blanket feature. If we cannot verify a technology claim for a market, we leave it off the page rather than assume the best case.
What we will not publish
We do not publish invented review counts, star ratings we have not earned, testimonials from people who do not exist, or speed figures we have not measured. Structured data on our pages matches what the page visibly says. If you find a claim on this site that you cannot square with reality, it is a mistake rather than a strategy, and we want to hear about it.
Prices and figures
Plan prices shown on destination pages are pulled live from our catalog, in the currency you are browsing in — they are not screenshots or hand-maintained tables that quietly drift. Competitor prices quoted in comparison articles are correct as at the article's published or updated date and are not monitored continuously; treat them as a snapshot and check the competitor's own site before deciding.
Updates and corrections
An article's modified date changes when the content actually changed. We do not refresh dates to look current — a guide that has not been revised keeps its original date, and you can judge its age honestly. When we correct a factual error, we fix the article rather than quietly deleting it. Corrections that change a recommendation are noted in the text.
Commercial relationships
We sell eSIMs, so we have an obvious interest in you buying one. That is why we also publish a page on when a travel eSIM is the wrong product for your trip. Our affiliate program pays partners who refer customers to us; it does not buy placement in our own comparison articles, and no third party pays to appear in or be omitted from our guides.
Found something wrong?
Tell us and we will fix it. Corrections to a factual claim are worth more to us than the article being left alone.
