TL;DR
- EU regulations that gave UK customers free roaming across Europe no longer apply since the end of the Brexit transition period on 31 December 2020.
- UK operators can now set their own roaming charges for EU destinations; some still offer inclusive EU roaming as a commercial choice, others charge daily or per-use fees.
- Ofcom requires UK operators to apply a £45 monthly data-spend cap abroad and send usage alerts, but this is a billing safeguard, not a free-roaming guarantee.
- Check your operator's roaming policy in writing before travel — the rules vary significantly between networks and tariff types.
- Alternatives such as a local EU SIM or a roaming eSIM can substantially reduce costs for frequent or extended travellers.
What changed when the UK left the EU
Until 31 December 2020, UK mobile customers benefited from EU roaming regulations that entitled them to use their phone in any EU or EEA country at domestic rates — the so-called "Roam Like at Home" framework. These regulations were part of EU law and applied because the UK was a member state. The end of the Brexit transition period meant that EU roaming rules ceased to have effect in the UK, and Ofcom confirmed there was no equivalent UK legislation to replace them automatically.
The practical consequence is that UK operators are no longer legally required to provide EU roaming at domestic rates. Some chose to continue offering inclusive EU roaming as a commercial feature to retain customers; others introduced daily or weekly roaming passes, fair-use data caps, or per-megabyte charges that did not exist before Brexit. The variation between operators, and even between tariffs from the same operator, means that what a customer was entitled to before 2021 may differ significantly from what they are entitled to now, even on the same network.
What Ofcom still requires from operators
Although Ofcom cannot restore the EU's Roam Like at Home framework, it retained certain consumer protections within UK telecoms law. Under Ofcom's rules, operators must apply an automatic data roaming bill cap of £45 per billing period when a customer is using data abroad. Once the cap is reached, the operator must cut off data roaming unless the customer actively opts to increase or remove it. Operators must also send a warning notification when a customer reaches 80% of the cap or a specified allowance threshold.
Ofcom also requires operators to provide clear information about roaming charges before a customer travels, including on their website and in the contract terms. The information duty means operators cannot hide roaming charges in small print, but it does not cap what they can charge. The result is a framework of disclosure and safeguarding, not one of price regulation for EU destinations.
How different operators approach EU roaming today
The post-Brexit landscape has split into broadly three models. Some operators include EU roaming within their standard monthly allowance, allowing customers to use their allocated minutes, texts, and data in EU destinations without additional charge, subject to fair-use policies. A second group offers roaming passes — typically a daily charge allowing full use of domestic allowances while abroad. A third group applies per-minute, per-text, or per-megabyte charges for EU use, often at rates significantly higher than domestic ones.
Which model applies to a given customer depends on their specific tariff and when it was taken out. Operators have in some cases continued to offer inclusive EU roaming on legacy tariffs while removing it from new plans. Customers who have been on the same plan for several years may find they still have EU roaming included, while a colleague on a newer plan from the same network does not. This inconsistency makes it particularly important to check your own plan details rather than relying on a general assumption about your network.
| Charge type | How it works | How to check your plan |
|---|---|---|
| Inclusive EU roaming | Domestic allowance usable in EU, often with a fair-use data cap abroad | Check tariff details page on operator website; look for "roaming destinations" list |
| Daily roaming pass | Fixed daily charge (typically £1–£2) auto-activates when you use your phone abroad | Confirm in account app before departure; check if pass covers calls, texts, and data |
| Per-use charges | Charged per minute, text, or MB; can escalate quickly for data-heavy usage | Request written confirmation of rates per destination from customer service |
| Ofcom £45 data cap | Mandatory billing safeguard; data cut off at £45 per billing period abroad | Applies automatically; check operator alerts settings in your account |
| Fair-use data cap | Operator-set limit on roaming data even within "included" plans (typically 12–25 GB) | Check tariff small print; look for "roaming fair use policy" document |
How to check before you travel
The most reliable way to understand what you will be charged is to locate the roaming information page on your operator's website, then search for the specific country you are visiting. Operators are required under Ofcom's transparency obligations to publish up-to-date roaming charge information, including any fair-use caps, before customers travel. The operator's account management app typically also allows you to check or activate roaming settings.
If the information online is unclear, calling or live-chatting with the operator's customer service team and asking them to confirm the applicable charges in writing gives you a paper trail. This is particularly valuable if you later receive an unexpectedly large bill, as it demonstrates that you sought accurate information in advance. Citizens Advice recommends keeping a screenshot of the charges page as published on the date before travel.
Alternatives for travellers who want to avoid roaming charges
For travellers who visit EU countries regularly or for extended periods, a local SIM from the destination country is often a cost-effective alternative. EU roaming regulations still apply within the European Union itself, meaning an SIM from a French, German, or Spanish operator allows calls and data throughout the EU at domestic rates. Purchasing a local SIM requires a compatible unlocked handset; if your UK phone is network-locked, you will need to request an unlock from your operator before travel.
eSIM technology offers a software-based alternative that avoids the need to physically swap a card. Several providers offer eSIM travel plans specifically designed for EU destinations, which can be activated on compatible devices before departure. These are not provided by the mobile operator whose physical SIM the device also carries; they are separate plans loaded digitally onto the phone. Customers should verify their handset supports eSIM and that their primary operator's network settings do not prevent a secondary eSIM from being active simultaneously.
What this means in practice
Tom takes a two-week holiday to Italy in summer 2025. He is on a mobile plan taken out in 2024 that does not include EU roaming. His operator charges a daily roaming pass of £1.50 per day when he uses his phone abroad. Over 14 days of active use, Tom pays £21 in roaming passes on top of his standard monthly charge. Had he bought a local Italian SIM for around £10–£15 with a generous data allowance, he could have used data throughout Italy and the rest of the EU at no additional per-day cost. The saving depends on his usage, but for two weeks the local SIM would likely have been cheaper. Tom checks his operator's website before his next trip and also reviews whether an eSIM travel plan would work on his handset.

Frequently Asked Questions
Do I pay extra to use my mobile in Europe after Brexit?
It depends on your operator and your specific tariff. Since the end of the Brexit transition period on 31 December 2020, UK operators are no longer legally required to offer free EU roaming. Some still do as a commercial choice on certain plans; others charge daily passes or per-use rates. Check your own plan's roaming terms on your operator's website or in the account app before you travel, rather than assuming the pre-Brexit rules still apply.
Which UK mobile networks still offer free EU roaming?
Ofcom does not publish a definitive real-time list of which operators include EU roaming, as operator policies change and vary by tariff. Some operators offer inclusive EU roaming on certain plans, while others charge daily passes. Rather than citing specific operators, which could be outdated, check the roaming section of your operator's website or contact their customer service directly for your specific plan. GOV.UK also publishes general travel guidance on using mobiles abroad.
How much can a UK operator charge for EU data roaming?
There is no UK regulatory cap on the per-unit or daily rate a UK operator can charge for EU data roaming. Ofcom does, however, require operators to apply an automatic £45 monthly data-roaming spend cap, cutting off data once that threshold is reached unless you actively raise or remove it. The £45 cap is a billing safeguard, not a price ceiling; actual rates per MB or per day vary significantly between operators and should be checked before travel.
What is a roaming cap and does my operator have one?
A roaming cap is a limit on how much you can spend on data while abroad in a single billing period. Ofcom requires all UK operators to apply a mandatory £45 data roaming spend cap per month, automatically cutting off roaming data when reached. Some operators also apply a separate fair-use data volume cap on inclusive roaming plans, beyond which they may throttle speed or charge for additional data. Check your operator's fair-use roaming policy for your specific tariff.
How do I check my roaming charges before travelling?
Go to your operator's website and find the roaming or travel section; search for the specific country you are visiting to see applicable charges. Your operator's account app often shows roaming settings and available roaming passes. If you are uncertain, contact the operator by live chat or phone and ask them to confirm charges for your specific tariff in writing. Keep a screenshot of the published rates as evidence in case of a billing dispute after your return.
