Roaming rates and fair usage

What each network charges per day abroad, where roaming is inclusive, and the fair usage rules that apply when you travel.

By SimDeals·Updated 30 July 2026·6 min read

Roaming is one of the few areas where the three networks differ in a way you can put a number on. If you travel regularly, the daily rate can matter more than the monthly line rental.

Key takeaways

  • O2 includes EU roaming; worldwide roaming is £4.00 a day.
  • Vodafone charges £1.60 a day in the EU and £4.26 a day worldwide.
  • EE charges £1.50 a day in the EU, £5.00 a day business roaming and £9.00 a day world roaming.
  • Fair usage applies everywhere, and roaming on unlimited plans is capped separately.

Daily rates by network

Roaming is charged differently on each network, so the right choice depends on where you travel rather than on which brand you prefer.

  • O2 — EU roaming included; worldwide roaming £4.00 a day
  • Vodafone — EU £1.60 a day; worldwide £4.26 a day
  • EE — EU £1.50 a day; business roaming £5.00 a day; world roaming £9.00 a day

Fair usage while roaming

A fair usage policy applies so that allowances are used for their intended purpose while abroad. On unlimited tariffs, the data you can use while roaming is capped rather than being unlimited — the unlimited part of the plan is a domestic allowance.

For most trips this is invisible. It only bites if you plan to use a UK SIM as your main connection while living or working abroad for months at a time.

The permanent roamer test

Inclusive roaming is designed for people who travel periodically, not permanently. If your usage abroad exceeds your usage at home, measured over a four month period, you are treated as a permanent roamer and standard out-of-bundle roaming charges apply.

Repeated breaches can lead to disconnection, with the standard £30 cease fee applied per subscription.

Choosing a network if you travel

If most of your travel is inside the EU, the difference between a daily fee and inclusive roaming adds up quickly across a year. If you mainly travel long haul, compare the worldwide day rates instead — the gap between networks is much wider there.

Work out roughly how many days abroad you expect in a year, multiply by the daily rate, and add it to the annual cost of the plan before you decide.
