How to Enable iD Mobile Data Roaming

Almost every device defaults to roaming being off — a deliberate anti-bill-shock measure rather than anything broken — so switching it on yourself before travel is a required step, not optional.

Android (Samsung, Pixel, and others)

  1. Head to Settings › Connections (Samsung) or Network & internet (Pixel) › Mobile Networks.
  2. Enable Data Roaming, confirming the warning about charges.
  3. Once you've landed, restart or toggle Aeroplane Mode for 30 seconds to pick up a local network.
  4. Confirm data works by opening a website before relying on it.

iPhone

  1. Settings › Cellular (or Mobile Data) › Cellular Data Options.
  2. Turn Data Roaming on.
  3. After arrival, toggle Aeroplane Mode to connect.
⚠ 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 — iD Mobile

iD Mobile uses the same APN for both UK data and international roaming: data.id. 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 — iD Mobile

Yes — iD Mobile includes EU roaming in 50+ destinations on most plans.

⚠ 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 My iD app or carrier website before travelling to avoid unexpected charges.

Verify your destination is covered

Rather than assuming the full list applies, it's worth double-checking since plans vary Three's full "Go Roam" list applies to you. Open My iD Mobile, 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 0333 003 7777 or live chat via iD Mobile website can confirm before departure if you're unsure.

Countries & Destinations Covered by iD Mobile

iD Mobile 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⚠ Available on selected iD Mobile plansAdd-on or roam charges may apply

Always verify specific country availability for your plan in the My iD app or on the iD Mobile website before travelling.

iD Mobile's Roaming Charges & Data Limits

Knowing how roaming charges apply keeps bills predictable. This is how it generally works on iD Mobile:

  • Beyond included zones, standard roaming rates apply and can be much steeper — a travel add-on before departure helps.
  • Hitting the roaming data cap can stop data completely or trigger a paid top-up, depending on plan settings.
  • For included destinations, the normal UK data, calls and texts allowance applies at no extra cost on most plans.
  • Some plans impose a fair use cap on roaming data, even within included zones — check the policy.
Tip: Your phone's data usage alerts (Settings › Mobile Data) are worth enabling to keep an eye on roaming data in real time.

Troubleshooting iD Mobile Roaming

  1. Cycling Aeroplane Mode for 30 seconds forces a fresh network re-scan.
  2. Switch on data roaming in Settings › Mobile Networks, as it defaults to off.
  3. Try manual network selection: Settings › Mobile Networks › Network Operators. Search for networks and select a iD Mobile partner manually.
  4. Verify the plan covers the destination country, as coverage varies by plan.
  5. Check signal strength — in remote areas or certain countries, iD Mobile may have limited partner coverage.
  6. Verify APN settings — check APN is still set to data.id and has not been replaced by a local carrier profile.
  7. Restart your phone after arriving to register on a local iD Mobile partner network.
  8. Contact iD Mobile support: 0333 003 7777.
