eSIM Network Map: Which Network Your eSIM Actually Uses

Your travel eSIM is not a network. It is a reseller riding a local carrier's towers, and which carrier that is changes by country and by provider. We pulled the network behind every plan across our 89 destination guides, 266 provider-network pairings in total. In 41 countries all three providers reach at least one shared carrier, so the decision comes down to price and hotspot rules. In the other 48, they split, and in 8 of those no two providers touch the same network at all: Germany, the UK, Australia, Bali, South Korea, Indonesia, Hong Kong and Puerto Rico. In those places the provider you pick is a coverage decision, not a pricing one.

The map

Search for a country or filter by region. Each row shows the local network operators, then the carrier each travel eSIM actually registers on. Country names link through to the full guide.

Last reviewed August 2026. Some plans reach more than one partner network, in which case every known carrier is listed. Where a provider registers on several, your phone picks the strongest available.

How to read this

The useful question is not which travel eSIM is best. It is which network you want to be on where you are going, and then which provider sells you access to it. A provider riding the market leader in Kenya may be riding the weakest of four operators in Poland, and nothing on its website will tell you.

Three practical rules fall out of the data. First, in cities this rarely matters: every national operator covers its own capital well, so a Same or Differs verdict changes little for a weekend in a European capital. Second, it matters most where terrain does: mountain roads, islands, deserts, national parks and long rural drives are where operators diverge, and where the wrong network becomes a real problem rather than an inconvenience. Third, when providers do share a network, stop comparing coverage claims entirely and compare price, hotspot policy and how each one handles top-ups, because the signal in your hand will be identical.

Method

Every entry comes from the research behind the destination guide it links to, where the network a provider uses is established alongside the coverage, pricing and carrier detail for that country. Names are recorded as the operator brands them locally, so an entry may differ from the parent group name. The Same and Differs verdict is computed by comparing carrier names across the providers that actually sell each country, treating local sub-brands as their parent network where they share infrastructure. Where a provider has no product for a country, it is marked Not sold here and left out of the verdict for that row.

Two honest limits. Wholesale agreements change without announcement, so an entry can go stale between reviews; we re-check on the same cadence as the guide it is drawn from. And a plan that reaches several partner networks does not let you choose between them manually, so treat multi-carrier entries as the set your phone may select from rather than a menu.
