The eSIM IP Address Problem: Your Data Exits Somewhere Else

An eSIM is a subscriber identity, not a network. When you install a travel profile, your phone starts presenting an IMSI that belongs to the plan's sponsoring operator, and that operator is almost never a carrier in the country you are visiting. Your handset then scans for local radio networks that have a roaming agreement with that sponsor, attaches to one, and from that moment you are a foreign subscriber on a visited network. The radio is genuinely local. The tower is a few streets away, the signal strength is real, and the coverage you get is the coverage that local operator has.

Your data does not stop there. In the mode the industry calls home routed roaming, the visited network does not put your traffic on the internet itself. It wraps the packets in a tunnel and carries them back across the roaming interconnect to a gateway inside the sponsoring operator's own core network, and that gateway is where your session gets its public IP address and where your traffic finally reaches the open internet. The alternative arrangement, local breakout, hands your session to the visited network's own gateway so the IP is local. Travel eSIMs are overwhelmingly home routed, which is why the country on the IP is the country of the gateway rather than the country of the tower.

Because the exit is a gateway in the sponsoring operator's core network, it follows the plan, not the place. A destination in Western Europe usually breaks out inside Europe, often through a pair of gateways so the value we publish is two countries rather than one, and a session may land on either. Destinations across Asia and the Pacific commonly break out through Hong Kong or Singapore. Plenty of destinations in Africa, South Asia, Central Asia and the Balkans break out through the United Kingdom. A handful of destinations in the Americas and the Middle East break out through gateways that have no obvious geographic relationship to them at all, and a small number genuinely do exit inside the country you are visiting.

Two consequences follow, and both are visible in the list below. The first is that regional bundles have an exit country too, so a plan covering twenty countries at once gives you the same gateway in every one of them. The second is that two plans sold for the same destination can break out differently, because they can sit on different underlying agreements. That is why the list is per plan rather than per country, and why we do not publish a single tidy country-to-country mapping that would be wrong for some of the rows. Where a value is written as a pair or a set, any of those countries is possible on a given session. Where it is written as a region rather than a specific country, that is what our upstream reports, and we would rather show you the coarse truth than invent a precise-looking answer.

Everything that keys off your IP address sees the exit country. Streaming services show the catalogue licensed for the exit country, not the one for where you are sitting. Search results, shop pricing, currency, tax display and default language follow the exit country. Local services that expect a local connection, from transit apps to regional news paywalls, may behave as though you are abroad even though you are not. There is also a latency cost that has nothing to do with content licensing. If you are in Tokyo and your traffic is hairpinning through a gateway in another territory before it reaches the internet, every request makes that round trip twice, and video calls and games feel it.

The second category is account security checks. Many services score a login by comparing the IP country against the country they associate with the account, and a mismatch pushes you toward an extra verification step or an outright refusal. This is worth understanding rather than fearing. A mobile IP belongs to a carrier or an eSIM aggregator, and those address ranges are usually scored more gently than a datacentre range, which is why a roaming exit tends to produce friction rather than a hard block. Adding a VPN on top does not undo any of this. It replaces the visible IP with the VPN's exit, so you swap one mismatch for another, and datacentre ranges are exactly the ones that get scored hardest.

This is not a defect and it is not something we invented. Any travel eSIM that works by roaming has a gateway somewhere, and therefore has an exit country, whether or not the seller mentions it. If you buy a travel eSIM from a large app-based brand, its data still breaks out at some operator's core network, and the country of that gateway is just as arbitrary as ours. The difference is that most sellers treat it as internal plumbing, so the buyer discovers it when a streaming app shows the wrong catalogue or a login gets challenged, and then has to guess whether the eSIM is broken.

So we are not claiming to have solved a problem the rest of the market has. We are claiming that the information should be on the product page, because it is the single most common source of confusion after purchase and it costs nothing to disclose. There is a limit to what disclosure can do. We publish the breakout country our upstream operator reports for each plan, and that is the country the gateway sits in. Third-party geolocation databases occasionally label an address range slightly differently, so a lookup site may show you a neighbouring country for the same session. If you see that, the published value is still the right thing to reason from, and the lookup site is the thing that is approximate.

An exit country is not anonymity, and this is the part we will not soften. Your IMEI is presented to every network you attach to. The visited operator knows which cells you camped on and when, and that record exists regardless of what IP the far end of your session shows. The sponsoring operator holds subscriber and session records for the profile. A public IP that resolves to a different country changes what a website infers about you, and it changes nothing about what a mobile network observes about you. Anyone selling you an eSIM on the promise that it makes you untraceable is either confused or lying. We do not ask for identity documents and we do not keep an account for you, and neither of those facts is a statement about what carriers can see.

It also does not apply to our other product, and people confuse the two constantly. The UK Number is a real UK +44 carrier line for incoming SMS and calls worldwide, $25 once with six months included and $15 every six months after that, and it carries no mobile data at all. No data means no data session, no gateway, no public IP address and no breakout country. It cannot appear in the list below because there is nothing to list. Everything on this page is about travel data eSIMs, which are prepaid data only, from $1.99, across 190 or more countries, with no phone number attached and top-ups onto the same eSIM without a new QR code.
