How to Use an eSIM in Europe as a UK Traveller
Since Brexit, UK travellers no longer benefit from free EU roaming. This means connecting to mobile data in France, Spain, Italy, Germany, or anywhere else in Europe can now cost a small fortune unless you plan ahead. The good news? An eSIM makes this simple, affordable, and completely stress-free.
What Is an eSIM?
An eSIM (embedded SIM) is a digital SIM card built directly into your phone. Instead of swapping out a physical plastic SIM, you simply scan a QR code and your phone connects to a local network within minutes. No queues at airport kiosks, no hunting for a SIM card shop when you land.
Why UK Travellers Need an eSIM for Europe
Before Brexit, UK residents could roam across the EU at no extra charge. That ended in January 2021. Since then, most UK networks charge roaming fees of £2–£5 per day in Europe — or worse, they apply data caps that leave you throttled at 2G speeds.
An eSIM gives you:
- Local European data rates — pay only for what you need
- Instant setup — activate before you leave home
- No contract — one-off data plans that suit your trip length
- Keep your UK number — your main SIM still receives calls and texts
Is My Phone Compatible?
Most modern smartphones support eSIM, including:
- iPhone XS and later
- Samsung Galaxy S21 and later
- Google Pixel 3 and later
- Many other Android devices from 2021 onwards
You can check in your phone's Settings under "Mobile Data" or "SIM Card" — if you see an option to "Add eSIM" or "Add Data Plan," you're good to go.

Tips for Using Your eSIM in Europe

Frequently Asked Questions
Can I use an eSIM alongside my UK SIM? Yes! Most modern phones support dual SIM (one physical SIM + one eSIM), so you can keep your UK number active while using your eSIM for data.
Do I need to unlock my phone? Your phone must be unlocked to use a third-party eSIM. Most UK phones bought outright are unlocked. If you bought yours on contract, contact your carrier to unlock it before travelling.
How much data do I need? For a typical 7-day holiday with maps, social media, and messaging, 5–10 GB is usually plenty. For longer trips or heavy streaming, opt for a larger plan.
