Everything UK travellers need to know about using their phone in Europe – from roaming to eSIMs to local SIMs.

If you're planning a trip to Europe from the UK, one of the first questions you might have is: do I need a separate SIM card? Since Brexit, using your UK phone in Europe is no longer automatically free. Here's everything you need to know about staying connected in Europe in 2026.
The Short Answer
You don't strictly need a new SIM card – your UK SIM will work in Europe with roaming. However, it will likely cost you £2–6 per day. A travel eSIM is a much cheaper alternative, giving you data across 34 European countries from just £0.16.
What Changed After Brexit?
Before Brexit, UK mobile users enjoyed free EU roaming under the 'Roam Like at Home' regulation. Since January 2021, UK carriers have reintroduced roaming charges for European travel. EE, Vodafone, Three, and O2 all now charge daily fees or require add-on purchases.

2. UK Carrier Roaming
Your UK SIM will work in Europe, but you'll pay daily charges. For a week-long trip, this typically costs £14–42 depending on your carrier.
3. Local European SIM
You can buy a local SIM in Europe, but you'll need to visit a shop, show ID, and you'll lose your UK number while using it. If visiting multiple countries, you'd need multiple SIMs.
Which European Countries Are Covered?
TripSIM's Europe plan covers all major European destinations including France, Spain, Italy, Germany, Greece, Portugal, Netherlands, Switzerland, Turkey, Croatia, Austria, Sweden, Norway, Denmark, Iceland, and 19 more countries – all on a single plan.
How Much Data Do I Need in Europe?
- Light use (email, maps, WhatsApp): 500MB–1GB per day
- Moderate use (social media, browsing): 1–2GB per day
- Heavy use (streaming, video calls): 3–5GB per day
- Most holidaymakers: 1GB per day is sufficient
Do I need a SIM card for Europe?
No, but you should get a travel eSIM to avoid expensive roaming charges. Your UK SIM will work with roaming, but daily charges of £2-6 add up quickly.
Will my UK phone work in Europe?
Yes. All UK phones work in Europe. The question is how much data will cost you. An eSIM gives you cheap data while keeping your UK number for calls.
Is WiFi enough in Europe?
Hotel and café WiFi is available but often slow and insecure. For navigation, ride-hailing, and staying in touch, having your own data connection via an eSIM is much more reliable.
