Since Brexit, UK travellers no longer benefit from EU roaming protections. That means your standard UK plan could charge you £5 or more per day just to use your own data abroad — and some networks cap speeds even on roaming bundles.
An eSIM for Europe is the clean fix. You download it before you travel, activate it when you land, and pay a flat rate for a set amount of data. No physical SIM to swap, no surprise charges on your monthly bill.
An eSIM is a digital SIM card built into your phone. Instead of inserting a physical SIM, you scan a QR code and the new plan loads directly onto your device. You can keep your UK number active at the same time — calls and texts come in as normal while your eSIM handles data.
Most phones sold in the UK since 2020 support eSIM. Check if your phone supports eSIM →
### Worldsim
Worldsim is one of the most established names in travel connectivity and covers over 100 countries. For Europe, they offer flexible data packages that work across the EU without needing to switch plans between countries. Their eSIM activates instantly and their app makes it easy to top up on the go.
Best for: Frequent travellers who want one provider that works everywhere, not just Europe.

### Airalo
Airalo is the world's largest eSIM marketplace. For Europe they offer regional eSIMs covering 39 countries under one plan — you buy once and it works across the continent. Data packages start from around £3 for 1GB, making it one of the cheapest options for short trips.
Best for: Budget travellers going to multiple European countries on one trip.
### Holafly
Holafly's Europe eSIM offers unlimited data — a genuine differentiator. If you are streaming, working remotely, or using maps heavily, the peace of mind of not counting gigabytes is worth paying a small premium for. They cover 35+ European countries.
Best for: Remote workers and heavy data users who want unlimited without caps.
### GiffGaff roaming
Not an eSIM but worth mentioning — GiffGaff still offers free roaming in 45 European destinations on its standard plans. If you are already a GiffGaff customer, you may not need an eSIM at all for European travel. Check your current plan first before buying anything.
Best for: Existing GiffGaff customers going to popular EU destinations.
Trip length is the main factor. For a weekend break, a small 1–3GB package is plenty. For two weeks of mixed use — maps, social, some streaming — budget for 5–10GB. For remote working, go unlimited.
Countries visited matters too. A regional Europe plan covers most of the EU but check the specific country list — some providers exclude Turkey, Switzerland, or the Western Balkans even on their Europe plans.
Speed varies by provider. Most eSIMs connect to local networks at 4G LTE speeds. A few budget options throttle after a daily limit — check the small print.
Set it up at home on Wi-Fi before you travel. Do not leave it until you are at the airport.
