Will Vodafone charge me if I only use the eSIM for data?

No, as long as data roaming is off on the Vodafone line. A daily fee is triggered by the Vodafone line using data, calls or texts abroad; with its data roaming off, only incoming texts and calls can reach it, and those are what your plan says they are.

Can I keep my Vodafone number while using the eSIM?

Yes. The eSIM is data only and sits next to your Vodafone SIM; calls and texts to your number still arrive on the Vodafone line.

Does the travel eSIM work on a Vodafone phone?

If the phone is unlocked and supports eSIM, yes; every iPhone since the XS and most Android flagships do. A phone still locked to Vodafone will refuse the eSIM until it is unlocked.

Vodafone international roaming: costs and the eSIM alternative

What Vodafone charges abroad in 2026 (day passes, included data, per-megabyte rates), when to keep it on, and how a travel eSIM sits beside it.

Short answer: Keep Vodafone roaming for a day or two, or where your plan already includes the country. For a longer trip, a travel eSIM for data costs a fraction of the daily fees, and your Vodafone SIM stays in the phone for calls and texts.

If you are a Vodafone customer heading abroad, the question is whether to pay Vodafone’s roaming or buy a travel eSIM for data and keep your Vodafone SIM for calls. Here is what Vodafone charges as it describes it in 2026, when it is worth keeping, and how the two sit together in one phone.

What Vodafone charges for international roaming

Vodafone UK charges a daily roaming fee in Europe on plans sold since 2021, around £2.40 a day, with eight-day and fifteen-day passes that work out cheaper; the Xtra plans include it. Further afield Vodafone sells passes for its Rest of World zones at about £6 to £7 a day, and charges per megabyte elsewhere. Older plans may include Europe; the Vodafone app shows what yours does.

Prices change and differ by plan, so check your own plan on the carrier’s site or app before you fly; the shape of the offer (a daily fee, slow included data, or per-megabyte rates) is what matters when you compare.

When to keep Vodafone roaming on

Keep Vodafone roaming on if your plan includes Europe, or for a weekend where calls on your own number are what matters.

When a travel eSIM is the better buy

Any trip of more than a few days: a prepaid plan for the country costs less than a week of daily fees.
Data for maps, video calls and a laptop hotspot: travel eSIM plans run at full 4G or 5G speed on local networks.
Several countries in one trip: one regional eSIM covers Europe, Asia or the Gulf without a new fee at each border.
Keeping your number: the Vodafone SIM stays in the phone for calls and texts; the eSIM carries the data.

A week in Thailand on Vodafone’s passes is about £6 to £7 a day, around £45. A ONE eSIM Thailand plan with 10 GB for 30 days on AIS or TrueMove H costs a few pounds.

Using a travel eSIM alongside Vodafone

Check the phone is unlocked. Phones sold by Vodafone UK since 2021 are unlocked; older ones can be unlocked free by asking Vodafone. Check before you fly, as a locked phone cannot use another eSIM.
Buy the plan for your destination and install it on Wi-Fi at home; the eSIM appears as a second line.
Set the travel eSIM as the mobile data line and turn data roaming on for that line only. Keep data roaming off on the Vodafone line, so no daily fee is triggered by a background update.
Leave the Vodafone line on for calls and texts if you want to be reachable; receiving texts abroad is usually free, calls may not be.
When you land, the eSIM connects to a local network and the plan starts. Your home number keeps working for calls.
