How to Avoid Roaming Charges on Your Summer Holiday in 2026
Quick answer
To avoid roaming charges abroad: turn data roaming off on your home SIM, install a prepaid travel eSIM before you fly and use it for data, keep your home SIM active only to receive calls and texts, and use Wi-Fi calling and apps like WhatsApp for free communication. This gives you a fixed, known data cost and removes any risk of a surprise roaming bill when you return home.
Roaming charges are the most avoidable cost of any holiday, yet they still catch travellers out every summer, most often UK visitors to Europe who assume roaming is still free. It is not always free anymore. This breakdown explains why, then walks through the exact steps to make sure your phone never quietly racks up roaming fees while you are away.
Why are roaming charges back in 2026?
For UK travellers, the guarantee of free EU roaming ended after Brexit, and several major UK networks reintroduced roaming fees for Europe. Whether you pay now depends entirely on your tariff: some include a fair-use EU allowance, others apply a daily roaming fee. Outside Europe, and for travel to long-haul destinations, standard roaming has always been expensive. The result is that you can no longer assume any destination is covered for free, which makes a deliberate setup worthwhile.
How to avoid roaming charges: step by step
- Turn data roaming off on your home SIM. This is the single most important step. With it off, your home line cannot connect to foreign networks for data at roaming rates.
- Install a prepaid travel eSIM before you fly. Set it up on home Wi-Fi and use it as your data line abroad. You pay a fixed amount upfront with a set allowance, so there is no metered roaming.
- Keep your home SIM active only for incoming calls and texts. On a dual-SIM phone you still receive messages and verification codes on your usual number, while the eSIM carries data.
- Use Wi-Fi calling and messaging apps. Enable Wi-Fi calling so you can be reached on your home number over Wi-Fi, and use WhatsApp or FaceTime for free calls and messages over data.
How to turn off data roaming on iPhone and Android
The setting takes seconds and is the foundation of avoiding charges.
| Device | Steps |
|---|---|
| iPhone (iOS) | Settings → Mobile Data / Cellular → Mobile Data Options → turn Data Roaming off |
| Android | Settings → Network & internet / Connections → Mobile network → turn Data Roaming off |
On a dual-SIM phone, check that roaming is off specifically on your home line, and confirm your travel eSIM is set as the active data line.
Travel eSIM vs roaming: the cost difference
A prepaid travel eSIM has a fixed price and a set allowance bought upfront, while roaming is billed at your carrier's rates and can quickly exceed an eSIM's cost with heavy use, plus it carries the risk of a bill arriving weeks later.
| Factor | Roaming | Travel eSIM |
|---|---|---|
| Cost | Variable, metered | Fixed, known upfront |
| Bill shock risk | High | None |
| Setup | None | Install once before you fly |
| Keeps your number | Yes | Yes (dual SIM) |
A data-only eSIM covers you for data only, while WorldSIM eSIM Pro adds calls, SMS and a real UK and USA number so you can make ordinary calls abroad without roaming fees too.

Will I still get charged if data roaming is off?
With data roaming off, your phone will not use foreign mobile data on that SIM, so you avoid data roaming charges. However, incoming calls and texts can still incur charges on some tariffs even with data roaming off, which is why many travellers rely on a travel eSIM for data and Wi-Fi calling or apps for communication.

For most trips, yes. A prepaid travel eSIM has a fixed price and a set allowance bought upfront, while roaming is billed at your carrier's rates and can quickly exceed the cost of an eSIM, especially with heavy data use. The eSIM also removes the risk of an unexpected bill after you return home.
