What roaming actually costs you in 2026

Roaming charges are one of those things you don't think about until the bill lands. Then you think about them a lot.

The "it's only £2 a day" trick

Most UK networks now sell roaming as a daily pass. It sounds harmless. £2, maybe £6 a day, and you carry on using your phone like you would at home.

The problem is the word daily. A fortnight in Spain isn't £2 — it's £2 × 14. And that's if your network is one of the cheaper ones.

• A two-week trip at £2/day: £28
• A two-week trip at £6/day: £84
• Two of you travelling: double it

You're paying for every day you're away, whether you used 4 GB or checked one map.

The bit that actually stings

Daily passes usually charge you the moment your phone touches a foreign network. Not when you open Instagram — when it connects. Land, take your phone off airplane mode, and a background app sync has already cost you the day.

And if you go outside your pass's country list — a stopover, a day trip across a border — you can fall off the pass entirely and onto pay-as-you-go rates. That's where the horror-story bills come from.

What an eSIM does differently

You buy a fixed amount of data for a fixed price, up front. That's it.

• No daily charge. You pay for data, not for days.
• No bill afterwards. You've already paid; there's nothing left to charge.
• If you run out, you top up — deliberately, because you chose to.

A 5 GB plan for a couple of weeks in Europe costs less than a few days of most daily passes. For most people that's plenty: maps, messages, a bit of scrolling, the odd photo upload.

So should you always use an eSIM?

If your trip is a day or two and your network throws in roaming free, honestly — just use it. We're not going to pretend otherwise.

But for most trips longer than about three days, a prepaid eSIM is cheaper, and the number you pay is the number you agreed to. No surprises when you get home.

That's the whole idea: get bars, not bills.
