In short
This section compares four ways to get mobile data abroad from the UK, with a guide per destination: your own network’s roaming, a travel eSIM, a local SIM and pocket Wi-Fi. Before you buy a SIM card for travel abroad, check your own plan. 10 of the 15 UK networks include Europe, each within its own fair-use terms, and all 15 include Ireland (checked on 24 October 2026).
This site is not affiliated with any of the networks mentioned here; we sell eSIMs. How we compare
Four ways to stay connected abroad
Of the four ways, only a local SIM takes your UK SIM out of the phone. Roaming keeps your number and allowance at your network’s price; a travel eSIM adds a data-only line beside your UK SIM.
Pocket Wi-Fi is a rented router that shares one connection between several phones. You collect it, charge it and return it.
| Way | Keeps your UK number | Fits when |
|---|---|---|
| Your UK network | Yes, calls and texts included | Your plan includes the country or charges little |
| Travel eSIM | Yes, on a dual-line phone; data only | Your network charges a lot or caps the data |
| Local SIM | Not while the UK SIM is out | You stay long and can buy it in person |
| Pocket Wi-Fi | Yes, the UK SIM stays in | A group shares one connection |
For the first two side by side, see eSIM vs physical SIM and roaming or eSIM.
Which way for which trip
Start with your network and change only if the trip breaks its limit. EE, Vodafone, Three, Sky and VOXI charge a daily rate or sell a pass in Europe on some or all plans; the other 10 include it (checked on 24 October 2026).
| Trip | Where to start |
|---|---|
| Europe on a plan that includes it | Stay on your plan; check the fair-use limit in the Europe guide |
| Europe on a plan that charges by the day | Add up your days of use against a Europe eSIM |
| It is outside every UK network’s Europe zone. Buy and install your eSIM before you travel: eSIM shops, including ours, may not open on Turkish networks | |
| Long-haul holiday | Compare your network’s pass with an eSIM in the country guide |
| A month with family | Data for the whole month, and keep your UK SIM in for bank codes |
| Cruise | No travel eSIM works on the ship’s own network; one covers port days on land networks only |
On a daily charge, a charged day is a day you use the phone, not a day you are away. Each network’s rules and dates sit in roaming on UK networks.
Country guides
Each guide answers three questions for one destination: do you need an eSIM from the UK, what your network charges there, and what our plan costs. Network figures carry a date and a link to the network’s own page.
Europe comes first: it is the trip most people take, and the one where your plan is most likely to cover you.
