How to Enable Three Data Roaming

Almost every device defaults to roaming off — a deliberate anti-bill-shock measure, meaning switching it on yourself before travel is required.

Android (Samsung, Pixel, and others)

  1. Head to Settings › Connections (Samsung) or Network & internet (Pixel) › Mobile Networks.
  2. Turning Data Roaming on brings a charges warning to confirm.
  3. A restart or 30-second Aeroplane Mode toggle after landing picks up the local network.
  4. Load a website first to confirm the connection is genuinely working.

iPhone

  1. Settings › Cellular (or Mobile Data) › Cellular Data Options.
  2. Turn Data Roaming on.
  3. After landing, switch Aeroplane Mode to connect up.
⚠ Set this up before leaving the UK — you may not be able to change it once your phone has no UK signal.

Roaming APN Settings — Three

Three uses the same APN for both UK data and international roaming: three.co.uk. You do not need to create a separate roaming APN. If mobile data stops working after arriving abroad, verify the APN is still set correctly and has not been overwritten by a local carrier profile.

EU Roaming Policy — Three

Yes — Feel At Home includes 71 destinations at no extra charge.

⚠ Post-Brexit reminder: UK mobile operators are not legally required to offer EU roaming as part of standard plans. Roaming policies vary by plan and carrier. Always check your specific plan's roaming terms in the My3 app or carrier website before travelling to avoid unexpected charges.

Verify your destination is covered

Plans vary, so it's worth double-checking rather than assuming Three's full "Go Roam" list applies to you. Open My3, go to your plan details, and look for the roaming or travel section — this shows exactly which countries are included and any daily cap on usage. Calling 333 (free from Three) or 0333 338 1001 can confirm before departure if you're unsure.

Countries Three Roaming Covers

Three roaming is available across multiple destination tiers. EU/EEA destinations typically use your UK allowance at no extra cost on eligible plans. Further destinations (USA, Australia, Asia) may require a roaming add-on or pay-per-use charges.

RegionCoverageTypical Cost
EU / EEA (27 countries)✅ Included on most plansUses UK allowance
Switzerland / Norway / Iceland✅ Included on most plansUses UK allowance
USA✅ Yes — USA included in Three Feel At HomeAdd-on or roam charges may apply
Australia / New Zealand⚠ Check your planAdd-on typically required
Rest of World⚠ Check coverage mapPay-per-use or add-on

Always verify specific country availability for your plan in the My3 app or on the Three website before travelling.

Three Roaming Data Caps & Charges

Understanding your roaming costs prevents unexpected bills. Here is how Three roaming charges typically work:

  • The standard UK allowance carries over to included destinations, usually without an extra charge.
  • Even within included zones, fair use caps can apply to roaming data on some plans.
  • Standard rates kick in outside included zones, often much higher — enable a travel add-on before departure.
  • Once the data cap is reached, expect a cutoff or a paid top-up, depending on the plan's settings.
Tip: Enable data usage alerts in your phone settings (Settings › Mobile Data) to monitor roaming data consumption in real time.

Troubleshooting Three Roaming

  1. Data roaming is disabled by default on most phones — turn it on in Settings › Mobile Networks.
  2. Not every plan includes every country — check the destination is covered.
  3. Restart your phone after arriving to register on a local Three partner network.
  4. Cycle Aeroplane Mode for around 30 seconds to trigger a fresh re-scan.
  5. Verify APN settings — check APN is still set to three.co.uk and has not been replaced by a local carrier profile.
  6. Try manual network selection: Settings › Mobile Networks › Network Operators. Search for networks and select a Three partner manually.
  7. Check signal strength — in remote areas or certain countries, Three may have limited partner coverage.
  8. Contact Three support: 333 (free from Three) or 0333 338 1001.
