Why do EE and Vodafone charge daily fees for EU roaming?

Since Brexit (2021) the regulatory requirement for free EU roaming ended. EE and Vodafone reintroduced daily fees on most plans to recover wholesale roaming costs. Higher-tier or enterprise plans can include EU, but standard SMB plans usually don't.

Can I switch UK networks mid-contract to get better EU roaming?

Not without paying out the remaining term (or an early termination fee). Realistically, your renewal date is when you switch. Plan 2-3 months before renewal to shop around without pressure.

Best UK Business Mobile for EU Roaming (2026): Network-by-Network Comparison

Last updated: April 2026

If you travel in the EU for work — even a few times a year — your business mobile's EU roaming setup matters. This is a ranked, honest comparison of what each major UK network actually gives you for EU roaming on a business tariff in 2026.

Note: this is specifically about roaming IN the EU (using your UK phone while physically abroad). For calls FROM the UK to EU destinations, see our best business mobile for calling EU 2026 comparison — different benefit.

The ranking

1. CTN Business

EU roaming: Inclusive across all EEA countries + Switzerland + Turkey + 50+ other destinations (83 total) Data cap while roaming: Generous; no hard uplift within fair use Price: £22-35/user/month on 36-month terms Fair-use limit: ~60 days/year of EU-primary use Verdict: Best coverage (widest country list). Best for any business where Switzerland and Turkey matter.

2. O2 Business

EU roaming: "Roam at Home" across most business tariffs — ~48 countries included Data cap while roaming: Typically 25GB EU data on "unlimited" plans Price: £20-32/user/month Key exclusions: Switzerland is NOT always on the list (check specific plan); some Balkan and Caribbean destinations missing Verdict: Solid default for EU-only travel. Falters if you visit Switzerland.

3. Vodafone Business

EU roaming: Charges daily fee (~£2-3/day) on most business plans. Some higher tiers include EU. Data cap while roaming: Varies by plan Price: £22-35/user/month + roaming fees unless on inclusive plan Verdict: Best avoided unless specifically on an inclusive-roaming plan. Daily fees accumulate fast for regular travellers.

4. EE Business

EU roaming: Daily fee (~£2-5/day) on most business plans. Enterprise and higher-tier plans can include EU. Data cap while roaming: Varies Price: £22-35/user/month + roaming fees unless on inclusive plan Verdict: Same pattern as Vodafone — best coverage in the UK, but EU roaming is an extra unless you specifically negotiate.

5. Three Business

EU roaming: Mixed — some plans include EU, some charge daily. Legacy plans were generous; newer ones less so. Price: £20-30/user/month Verdict: Check your specific plan. Quality varies widely.

The maths for a typical 10-person team

Assumption: 10 staff, moderate EU travel (average 8 days/year in EU per person), 36-month term.

Network	Base cost / year (10 staff)	Roaming cost / year	Total estimated annual
CTN (50GB / 500 int)	£3,120	£0 (inclusive)	£3,120
O2 Business	£2,880	~£0 (Roam at Home, EU only)	£2,880
EE Business + daily roaming	£2,640	~£200 (8 days × 10 × £2.50)	£2,840
Vodafone + daily roaming	£2,640	~£200	£2,840

So on pure EU-only travel for a moderate-travel team, O2 narrowly edges CTN on price. But: if any of those 10 staff visits Switzerland once a year, or Turkey, or takes a Balkan holiday mixing work — CTN pulls ahead. Plus CTN includes inclusive UK-to-EU calling (O2, EE, Vodafone standard plans don't).

Where each wins

If you travel only within EEA, low-ish frequency

O2 Business — Roam at Home is very good, price competitive.

If you ever visit Switzerland or Turkey

CTN — both are on the inclusive list; O2 sometimes excludes Switzerland.

If you need inclusive UK-to-EU calling as well as roaming

CTN — 39-country call list includes all EEA plus USA/Canada.

If you're a heavy traveller on unlimited data

CTN for the wider country list; but check fair-use caps on any "unlimited" plan carefully.

If you need to manage a large team (20+) on a single account

Both CTN and Vodafone Business handle multi-user accounts well; Vodafone Business has the better enterprise admin portal but charges more for EU roaming on standard plans.

If coverage in the UK is the priority over roaming

EE for UK rural coverage, but add a roaming bolt-on or accept daily fees for EU trips.

If you're genuinely on a budget

Three Business or O2 Business entry-level plans. Check EU roaming specifics; some plans include it, some don't.

The pitfalls to watch regardless of network

Fair-use data caps on "unlimited" plans — usually 20-40GB EU data per month
Switzerland exclusions — default-excluded from many "EU" inclusive offerings
Turkey and North Cyprus — on some plans, not others
Former Yugoslav states — Croatia and Slovenia are EU (inclusive on most plans); Serbia, Bosnia, Montenegro, North Macedonia often not
Auto-renewal to more expensive plans — at renewal, make sure the new plan still includes what the old one did; networks often change bundle composition

Our honest recommendation

Default recommendation for UK SMBs that travel in the EU occasionally: CTN Business or O2 Business. Both include EU roaming; CTN has wider coverage and inclusive UK-to-EU calls; O2 is marginally cheaper at entry tier but has tighter country list.

For enterprise and larger teams with mixed needs: quote both Vodafone Business (with explicit EU-inclusive negotiation) and CTN. The big enterprise Vodafone plans can be competitive; the standard ones aren't.

Avoid: any plan where EU roaming is a daily fee unless you've explicitly decided the base tariff's other benefits outweigh that cost.

FAQs

Which UK business mobile has the widest EU roaming coverage?

CTN (83 destinations including all EEA, Switzerland, Turkey, USA, Canada, Australia, and more) has the widest list. O2's Roam at Home covers ~48 destinations. EE and Vodafone standard plans typically use daily fees rather than inclusive lists.

Is O2 Business cheaper than CTN for EU roaming?

At entry tiers, yes — marginally. But O2 sometimes excludes Switzerland and has a narrower country list. For mixed travel (including Switzerland or Turkey), CTN usually works out cheaper after accounting for the alternative daily fees.

Are EE and Vodafone always more expensive for EU roaming?

Not always. Their enterprise-tier plans can include generous inclusive roaming. Standard SMB plans typically charge daily fees unless you specifically add a roaming bolt-on. Check the specific plan at renewal.

Does this ranking change if I only travel to one country (say, France)?

Less so. All UK networks' roaming offerings include France (EU). Pick on overall plan value. For France-only travel, any EU-inclusive plan works.

Can I switch networks mid-contract?

Not without paying out the remaining term (or an early termination fee). Realistically, renewal is when you switch. Plan ahead — renewals tend to auto-roll in subtly different terms.
