Is Switzerland included in EU roaming on UK business mobiles?

Usually no — Switzerland isn't in the EU, so EU Roam at Home rules never applied. Most UK business plans treat Switzerland as standard international roaming. CTN's business tariffs include Switzerland in the inclusive 83-destination list.

How much do UK networks charge for Switzerland roaming?

Typically £2-5 per day on EE and Vodafone business plans. O2 and Three vary by plan. A 5-day Swiss business trip can add £10-25 per line in roaming fees. CTN business tariffs include Switzerland at UK rates.

Why did I get charged for Switzerland even though I only had a layover?

Roaming charges trigger when your phone connects to a foreign network, not when you leave the airport. A 90-minute layover with your phone on is often enough to trigger a daily fee. Keep phone in airplane mode during layovers if not on an inclusive plan.

How do I avoid Switzerland roaming charges?

Four options: (1) airplane mode + WiFi; (2) buy a Swiss / Europe eSIM before travel (~£10-20 for a week); (3) add a day-rate roaming bolt-on for the trip; (4) switch to a business tariff that includes Switzerland in inclusive roaming (like CTN).

Switzerland is the most consistently painful roaming destination on UK business mobiles. It's surrounded by EU countries, you visit it like you'd visit any other European country, but your phone bill treats it completely differently.

Here's why, what each network charges in 2026, and which business mobile plans actually include it.

Why Switzerland isn't covered by "EU inclusive" plans

Switzerland is not in the EU. EU Roam Like At Home regulation never applied to Switzerland. When UK networks built "EU inclusive" plans, Switzerland wasn't automatically included.

Many UK business plans labelled "EU roaming inclusive" quietly exclude Switzerland from the country list. You only notice when you're stood in Zürich airport and you've just been charged £5 for a minute's call.

What each network charges for Switzerland in 2026

Approximate rates for UK business mobile customers roaming in Switzerland:

Network	Standard roaming rate (no bolt-on)
EE Business	£2-5/day "roam abroad" or per-minute rates (~£1-2/min calls, ~£5/MB data outside bundle)
Vodafone Business	£2-3/day on daily roaming plans; higher on plans without
O2 Business	Roam at Home includes ~48 countries, but Switzerland is NOT on that list. Standard roaming rates apply — typically £2-4/day on newer plans
Three Business	Mixed — some legacy plans cover Switzerland; most newer ones don't
CTN Business	Switzerland IS on the 83-destination inclusive list. UK allowance applies at UK rates.

Worth noting: these rates are day-based caps on most networks now, not per-minute. So a 5-day Swiss business trip costs £10-25 in roaming uplift per line, per staff member. Across a 5-person team, £50-125 for one trip.

Real-world Swiss business travel

Common scenarios:

Banking / finance trips — London firms visiting Zürich, Basel, Geneva offices
Pharma visits — Basel (Roche, Novartis) pharmaceutical supply chain
FinTech — Swiss FinTech hub in Zug and Zürich
Ski season leadership offsites — St Moritz, Verbier, Zermatt
Watch and luxury goods — Baselworld (though now defunct), Geneva timepiece events, brand HQ visits
Geneva international organisations — WHO, WTO, UN, ICRC visits for UK consultants and contractors
Transit via Zürich / Geneva airports — common connection airports; even a layover can trigger roaming charges if phone is switched on

What to do if you're on a plan that charges for Switzerland

Option 1: Airplane mode except at WiFi

The free option. Turn off cellular entirely, use WiFi at hotels, cafes, trains. Works but inconvenient and risky if you need to be reachable.

Option 2: Buy a Swiss or Europe-wide eSIM

Services like Airalo, Holafly, NomadSIM sell Swiss or regional Europe eSIMs. £10-20 for a week of data. Activated from your phone before you land. Your UK number stays on for incoming calls/SMS.

Option 3: Day-rate roaming bolt-on

Some networks sell "Europe Plus" or "World" day bolt-ons that add Switzerland. Typically £2-5/day when actively added. Activate before leaving.

Option 4: Switch to a tariff that includes Switzerland

O2's Roam at Home doesn't always include Switzerland despite including much of the EU. CTN's business tariffs include Switzerland in the inclusive 83-destination list. If you're a regular Swiss visitor, this is the simplest fix.

The "I didn't use my phone there" problem

Many UK business travellers have been billed for Switzerland roaming they didn't consciously use:

Phone auto-connected to a Swiss network near the French/German border, ran background data sync, triggered the daily fee
Received a call or text that the phone auto-answered briefly
Brief airport layover — phone switched on, connected to local airport network
Alpine skiing — phone connected to Swiss mast from the French side of a resort

To avoid this, set roaming preferences: data roaming off when not on an inclusive plan, and turn off voice roaming for days you're not expecting to work.

Liechtenstein — the other small surprise

Liechtenstein (tiny principality between Switzerland and Austria) is actually on CTN's inclusive roaming list AND inclusive call list. But on many other UK business plans, it's in the Swiss rate category and charges similarly.

If you're visiting Vaduz, the banking sector, or transiting through, worth knowing Liechtenstein has its own rules on many plans.

FAQs

Is Switzerland included in O2's Roam at Home?

Not always. O2's Roam at Home covers ~48 destinations but Switzerland is excluded from some plans' versions of the list. Check your specific plan's country list — don't assume.

How much is a daily roaming fee for Switzerland on EE?

Generally £2-5 per day per line, depending on your specific EE plan. Some higher-tier EE Business plans include Switzerland in inclusive roaming; most don't.

Does CTN include Switzerland in inclusive roaming?

Yes. Switzerland is on CTN's 83-destination inclusive roaming list. Your UK allowance applies at UK rates when physically in Switzerland — same as UK usage.

I only stopped in Zurich airport for a layover — why was I charged?

Roaming charges trigger when your phone connects to a foreign network, not when you leave the airport. A 90-minute layover with your phone on is enough to trigger a daily fee. Keep phone in airplane mode for layovers if not on an inclusive plan.

Can I use my Swiss Franc ATM debit card on roaming WiFi calling?

Yes — the bank activity is separate from the roaming charge. ATM withdrawals, contactless card use, Apple Pay etc. aren't part of mobile roaming charges. Only phone usage is.

Does Liechtenstein cost the same as Switzerland?

On some networks yes, on others no. Liechtenstein is on CTN's inclusive list. Always check the country list on your specific plan.
