UK Roaming Fair Use Limits: How Long Can You Roam Abroad? (Infographic)

On a UK network you can usually roam abroad for about two months in every four before fair use rules apply. O2 counts more than 63 days abroad in four months as unfair use, Vodafone sets the line at 62 days or more roaming in a four-month period, EE expects you to spend two months or more in the UK in any four-month period, and Three allows two months of roaming only in Go Roam destinations in a rolling 12-month period. This infographic compares the four limits side by side.

Last checked: 27 October 2026. The limits come from EE's terms, O2's fair use policy, Vodafone's acceptable use policy and Three's Go Roam fair use policy. Terms change, so check your own network's current policy before a long stay abroad.

Key figures

• EE, 2 months: EE expects two months or more in the UK in any four-month period, or that you mainly use your allowance in the UK. If not, EE can ask for an explanation and add surcharges.
• O2, 63 days: more than 63 days abroad in four months counts as unfair use. O2 texts you first, then charges surcharges, such as £3.50 per GB.
• Vodafone, 62 days: 62 days or more roaming in a four-month period, with more use abroad than in the UK, can lead to extra charges after two weeks' notice.
• Three, 2 months: roaming only in Go Roam destinations for two months in a rolling 12-month period can lead to roaming being suspended.
• Safest approach for a semester abroad: use a travel eSIM or local SIM for data and keep UK roaming off.

What this means

Three of the four networks measure over a four-month window, so more than about nine weeks away in any four months can take you past the O2 and Vodafone limits, which a single university term abroad can easily do. Three works differently, counting over 12 months, and the outcome there is suspension rather than a surcharge. The rules are written for holidays, not semesters, placements or gap years.

The fix the infographic suggests is simple: keep your UK SIM in the phone for calls, texts and bank codes with data roaming off, and use a long-validity travel eSIM for data. Browse long-stay plans for countries such as Spain or regional plans, and check your phone first with our compatibility checker.
