We sell travel eSIMs, so there is no single network to check. Each bundle connects you to the local operators in the country or region it covers, and every bundle lists exactly which countries those are before you buy.
On a bundle covering more than one country, open Covers N countries and search for yours — it will tell you plainly whether it is included.

Roaming on your plan
We run on the UK's biggest mobile network. Its 4G covers 99% of the UK population, including most rural areas.
5G is available across London, Manchester, Birmingham, Glasgow, and hundreds more towns and cities.
On a monthly plan with us, roaming is included across 41 European destinationsat no extra cost — your data, calls and texts work just like at home, up to your plan's roaming data limit and as long as you are calling or texting a UK number — dialling a local number in the country you are in counts as an international call on your line and will not connect.
Included on every plan, Wi-Fi calling lets you make and receive calls over Wi-Fi when mobile signal is weak — perfect for basements, offices, and rural areas.
