How to Enable Tesco Mobile Data Roaming

Almost every handset comes with roaming off out of the box, specifically to prevent accidental charges — a step you take yourself.

Android (Samsung, Pixel, and others)

  1. Settings › Connections (Samsung) or Network & internet (Pixel) › Mobile Networks.
  2. Enable Data Roaming, then confirm the charges warning shown.
  3. After landing, restart the phone or cycle Aeroplane Mode for 30 seconds to register locally.
  4. Test using a website or app before relying on the connection.

iPhone

  1. Settings › Cellular (or Mobile Data) › Cellular Data Options.
  2. Set Data Roaming to ON.
  3. Toggling Aeroplane Mode after arrival helps connect to the local network.
⚠ Do this before departure — without a UK signal, some phones won't let you change the setting at all.

Roaming APN Settings — Tesco Mobile

Tesco Mobile uses the same APN for both UK data and international roaming: prepaydata.mobilebroadband. 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 — Tesco Mobile

Yes — included in most Tesco Mobile plans in EU destinations.

⚠ 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 Tesco Mobile app or carrier website before travelling to avoid unexpected charges.

Confirming coverage for your trip

Rather than assuming a general zone, check your specific plan's terms O2's general zone applies. In My Tesco Mobile, look under your plan details for a "Roaming" or "Travel" section, and note which countries are covered and whether there's a daily usage cap. Calling 4455 (free from Tesco Mobile) or 0345 301 4455 can confirm anything before departure — it's harder to resolve billing surprises once you're already abroad.

Where Tesco Mobile Roaming Is Included

Tesco 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.

USA✅ Yes — available on eligible plans with a roaming add-onAdd-on or roam charges may apply

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

Tesco Mobile Roaming Charges & Data Caps Explained

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

  • Beyond covered zones, rates revert to standard and can climb steeply — check for a travel add-on before leaving.
  • Hitting the cap means either a full data stop or a paid top-up, depending on the specific plan.
  • Travelling within included destinations means the regular UK allowance applies, no extra charge on most plans.
  • Usable data can be capped even within included zones under a fair use policy — worth a check.
Tip: Your phone's data usage alerts (Settings › Mobile Data) are worth enabling to keep an eye on roaming data in real time.

Troubleshooting Tesco Mobile Roaming

  1. A 30-second toggle of Aeroplane Mode is enough to force a network re-scan.
  2. Switch data roaming on in Settings › Mobile Networks, since it's not on by default.
  3. Try manual network selection: Settings › Mobile Networks › Network Operators. Search for networks and select a Tesco Mobile partner manually.
  4. Verify the destination country is covered, since plans differ in their coverage.
  5. Check signal strength — in remote areas or certain countries, Tesco Mobile may have limited partner coverage.
  6. Verify APN settings — check APN is still set to prepaydata.mobilebroadband and has not been replaced by a local carrier profile.
  7. Restart your phone after arriving to register on a local Tesco Mobile partner network.
  8. Contact Tesco Mobile support: 4455 (free from Tesco Mobile) or 0345 301 4455.
