Europe eSIM at a glance
Europe eSIM plans from RoamingFlex cover 47 European countries on the EU-wide carrier networks (Vodafone, Orange, Deutsche Telekom, TIM, and local equivalents). 5G is now standard across the EU's biggest cities. 4G LTE blankets the rest, including the Alps, the Greek islands, and the Scottish Highlands. Pick a single-country plan if you're visiting one place, or use a regional Europe plan if you're hopping across borders. The QR-code activation works the same way regardless of where you land.
Best time to visit: April to June and September to October are sweetest across most of Europe. July and August are hot and crowded in the south; the north (Scotland, Scandinavia) is at its best then.

Europe eSIM frequently asked questions
Does one Europe eSIM plan work across multiple EU countries?
Yes if you pick a regional Europe plan. Single-country plans cover only the country you bought. Most EU countries also have single-country options if you're only visiting one place.
Will an EU eSIM cover the UK after Brexit?
Some regional Europe plans include the UK, others don't. Check the country list on the plan page before buying. The dedicated UK plan is always the safer pick if Britain is the main stop.
Does it work on European trains (Eurostar, TGV, ICE)?
Yes. Coverage on the main rail corridors is reliable, with tunnel sections briefly dropping signal. The Eurostar through the Channel Tunnel needs separate UK and France plans because mobile data doesn't roam in the tunnel.
How much data do I need for a 2-week European trip?
5GB is enough for most travellers. If you're mostly in cities with hotel and cafe WiFi, 3GB works. Cross-country drivers and content uploaders should pick 10GB.
