Local Network Map: Who Carries Your Data Abroad

What the file holds

Source: HelloRoam package feed, read 17 August 2026. The feed lists operators for every destination on sale. It carries no speed, latency or throughput figure, and we took no reading of our own.

One operator means no second chance

HelloRoam lists exactly one local operator in 117 of 185 destinations. In those 117, no second network exists to catch a dropped connection. No plan and no carrier can route around a dead spot there. Coverage is a property of the country, not of the product you bought.

The other 68 destinations list more than one operator, and 4 is the highest count on file. HelloRoam marks no operator as preferred in those destinations. An eSIM attaches to one of the names listed. The file does not record which.

The operators that show up most

Orange appears on the list in 27 destinations, more than any other operator. That concentration is worth knowing before you read a roaming rate card. Your carrier is buying access to these same companies and reselling it to you by the day.

What this file does not say

The file records no speed. The file records no latency. A 5G label states that an operator runs a 5G network, and nothing more. We publish no speed figure anywhere on this site, because we measure none, and a generation label is no substitute for one.

It also does not name a routing target. Japan lists KDDI/au, NTT docomo, Rakuten Mobile and SoftBank. Writing that a Japan eSIM "uses" any one of them would be an invention. The list is alphabetical, and alphabetical order carries no meaning.

Operator lists for popular destinations

Every destination page on this site carries its own operator list where the file has a row. Where the file has no row, the page shows nothing rather than a guess.

Common questions

Which local operator does a travel eSIM use?

The answer changes by destination. HelloRoam publishes an operator list for 185 destinations. 117 of those list exactly one operator, so the answer there is fixed. 68 list more than one, and HelloRoam marks no default among them. A published list is an attachment set, not a routing instruction.

Does roaming get a better network than an eSIM?

Both ride local operators. A roaming agreement is a contract to use another company's masts, and a travel eSIM is a wholesale arrangement to do the same thing. The operator list does not change when the payer changes. What changes is the price on the bill.

How many destinations have only one local operator?

117 of 185. In those destinations there is no second network to fall back on, for roaming or for an eSIM. If the one operator has no signal where you stand, no amount of money buys a different mast.

Does this dataset measure network speed?

No. The file records operator names and generation labels such as 5G and 4G. A generation label states what a network supports. It is not a measured speed, and we ran no speed test to produce this page.
