How we compile per-country eSIM connectivity
We build one honest connectivity profile per country from public-record telecom facts — which networks exist, which radio generations are commercially launched, which bands they use — then flag exactly what we're still verifying. We never store or fabricate a plan price; those come from the eSIM provider feed.
Who’s behind this site
eSIM by Country is an independent publisher operated by VentureCorp, Inc. We are not a mobile carrier, an eSIM provider, or a reseller, and we do not accept payment to change a coverage figure. The site answers one question accurately: what is the mobile-connectivity picture for a given country, and is a travel eSIM the right option there?
Where our data comes from
| Data | Source | Used for |
|---|---|---|
| Per-country MNO roster, 3G/4G/5G status & key bands | Wikipedia per-country "Telecommunications in <country>" + Mobile Country Code pages, and the List of 5G NR networks; cross-checked against the public MCC/MNC table — compiled facts, no source prose republished | The connectivity layer on every country page |
| 5G & coverage context | GSMA Intelligence and ITU ICT statistics (cited references for commercial-5G and population-coverage context) | 5G-availability framing and the by-region rollups |
| Country spine (ISO2, calling code, capital, region) | ISO 3166-1 (iso2) + ITU-T E.164 (calling codes) + DataHub country-codes (capital/region, PDDL public-domain) | Every page's country identity and the region comparison |
| Plan prices | AFFILIATE FEED ONLY — Airalo / Holafly / Saily fill the plans pane at serve time; this dataset stores NO price and we fabricate none | The affiliate plans pane (intentionally empty until the feed fills it) |
The connectivity facts (which MNOs exist, which generations are commercially launched, which bands are deployed, ISO2 / calling code / region) are public-record and not copyrightable (Feist); the capital/region spine is PDDL public-domain. We did not scrape any proprietary coverage or pricing database. Plan prices are affiliate-fed, never fabricated — every country's plans pane ships empty until the provider feed fills it.
How we calculate
Each country is enumerated from the ISO/country-code spine, then its MNO roster, commercially-launched radio generations (3G/4G/5G per the public 5G-network list), travel-relevant LTE/5G bands and local-eSIM support are compiled from the per-country telecom references and a qualitative roaming-vs-eSIM verdict is written. We re-pull on a semiannual cadence because 5G launches, new bands and 3G sunsets move fast.
What we deliberately leave out. We store no plan prices, plan names, validity periods or data amounts — those are supplied by the eSIM provider feed at publish time, and a prior fabricated-price version was removed. We also name no "best" provider and rank no products; our buyer's guides are neutral and point you back to your destination's connectivity profile.
Independence & how we make money
Some links on this site may be affiliate links to travel-eSIM partners (Airalo, Holafly, Saily); if you act on one we may earn a commission at no extra cost to you. Partners never see or influence which coverage facts we publish, and no placement is for sale.
Keeping it current
5G launches and 3G sunsets move fast, so we re-run the per-country telecom + ISO/MCC spine pull on a semiannual cadence and flag low-confidence rows as "verifying" rather than guessing. Each page carries its verification date; current verification: June 2026.
