Good to know in Switzerland

Switzerland is in the European roaming zones of EE, Vodafone and O2, so check your plan first. An eSIM is worth it if your plan charges a daily fee or caps your roaming data.

The main mobile networks in Switzerland are Swisscom, Sunrise and Salt. Travel eSIMs connect to one or more of these, so check which network a plan uses if you're heading somewhere remote.

Switzerland eSIM FAQs

Is Switzerland included in EU roaming?

On most UK networks, yes. O2 includes it in its Europe Zone, and EE and Vodafone treat it like the EU, so you pay their usual European daily charge if your plan doesn't include roaming.

How much data do I need for a week in Switzerland?

For maps, messaging and social media, 5–10GB is plenty for a week. If you'll stream video or use your phone as a hotspot, go for an unlimited plan where one is available.

Will I still get calls and texts on my UK number?

Yes. Keep your normal SIM switched on and you'll receive calls and texts as usual. Your UK network may charge for these abroad, so check their roaming rates.

Is an eSIM cheaper than roaming in Switzerland?

Usually, yes. A Switzerland travel eSIM starts from £3.34 as a one-off payment, while UK networks often charge a daily roaming fee for every day you use your phone.
