What Brexit Changed for Phone Users

The UK left the EU single market on January 1, 2021. Among the practical consequences: the UK was removed from the EU roaming regulation. Mobile carriers were no longer obligated to apply "roam like at home" pricing for UK travel.

The initial concern was that EU travellers in the UK (and UK travellers in the EU) would immediately face the kind of bill-shock that plagued pre-2017 roaming. In practice, the transition was more gradual — many carriers continued offering relatively affordable EU/UK roaming for commercial reasons. But the situation has evolved, and in 2026, there is significant variation between carriers and plan types.

The Current Landscape for EU Travellers in the UK

German, French, and Spanish major carriers: Most major EU carriers (Deutsche Telekom, Orange, Telefónica, Vodafone EU) continue to include the UK in their roaming bundles as a commercial offering, though they are no longer legally required to. These carriers typically apply either their standard EU roaming rates or a small surcharge (€0.00–€0.05/min above domestic rate).

EU budget and MVNO carriers: Budget operators and MVNOs (Mobile Virtual Network Operators) more frequently exclude the UK from their roaming packages post-Brexit, or charge a separate UK roaming add-on. Rates range from €0.10 to €0.40/min for calls in or from the UK.

UK travellers in the EU: British carriers face the same situation in reverse. EE, O2, Vodafone UK, and Three UK all changed their roaming policies post-Brexit. As of 2026, most major UK carriers charge a "roaming pack" of £2–£10/day for EU use, rather than including EU roaming in standard plans.

The Specific Cost Scenarios

Scenario 1: EU resident calling a UK number from their home country

Calling +44 numbers from an EU phone is international calling — not affected by roaming rules at all. This was expensive before Brexit and remains so.

Typical rates for calling UK numbers from EU mobiles:

  • From a German mobile to UK landline: €0.15–€0.45/min
  • From a French mobile to UK mobile: €0.20–€0.60/min

VoIP alternative rate to UK landline: €0.010–0.015/min

VoIP alternative rate to UK mobile: €0.015–0.025/min

The savings here are dramatic: calling UK clients from an EU mobile can cost 20–40x more than calling via VoIP.

Scenario 2: EU resident travelling in the UK

Using your EU SIM to make calls while physically in the UK. Whether this triggers roaming charges depends on your specific carrier's UK policy.

If your carrier still includes UK roaming: You pay your standard plan rates (effectively free if calling is included).

If your carrier charges for UK roaming: Rates of €0.10–0.40/min apply, or a daily roaming fee of €2–5 activates automatically.

Scenario 3: UK resident calling EU numbers from the UK

Calling EU numbers from a UK landline or mobile is international calling. Typical UK mobile rates to EU destinations range from £0.15–£0.50/min, depending on carrier and destination.

VoIP alternative to most EU landlines: £0.010–0.020/min

Scenario 4: UK resident travelling in the EU

As above — now subject to each UK carrier's EU roaming policy rather than guaranteed EU roaming. Budget appropriately: assume £2–£10/day for a roaming pack, or use VoIP over Wi-Fi.

The Confusion Factor

The complexity here is significant. Before Brexit, EU roaming was straightforward: if your carrier was in the EU and you were in the EU, you paid domestic rates. Now:

  • Your carrier may or may not include the UK voluntarily
  • The terms vary by plan tier within the same carrier
  • Terms change as carriers update commercial policies
  • UK carriers have their own independent policies for EU roaming

The safest approach for both EU and UK travellers:

  1. Check your specific carrier's current UK/EU roaming policy before travelling
  2. Do not assume last year's experience applies — policies have changed repeatedly since 2021
  3. For all outbound calling that does not depend on being physically present (i.e., you are calling someone else, not receiving a call), VoIP over Wi-Fi gives you a consistent, cheap rate regardless of which side of the Channel you are on

A Note on Calling UK Numbers from Any VoIP Service

UK numbers have a nuanced rate structure. The +44 country code covers:

  • Geographic landlines (01/02 prefixes): Cheapest to call, typically €0.010–0.015/min via VoIP
  • Mobile numbers (07 prefixes): More expensive due to mobile termination rates, typically €0.015–0.025/min
  • Non-geographic numbers (03, 08, 09): Rates vary significantly. 03 numbers are charged at geographic rates. 08x and 09x numbers can be substantially more expensive — always check before calling these.

This rate differentiation between UK landlines and mobiles is more pronounced than in most EU countries, where mobile termination rates have been regulated down to near-landline levels. It is worth being aware of when calling UK contacts.
