SMARTY Roaming Settings UK 2026 Roaming

SMARTY roaming settings for international travel. SMARTY runs on the Three (SMARTY runs on Three's network). You use the same APN when abroad: smarty. Enable data roaming in your phone settings before travelling and check your plan includes your destination country.

How to Enable SMARTY Data Roaming

Roaming ships with roaming off on almost every device — 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. Switch Data Roaming on, accepting the warning about charges.
3. On arrival, a restart or 30-second Aeroplane Mode toggle picks up a local network.
4. Open a website to confirm the data connection before depending on it.

iPhone

1. Settings › Cellular (or Mobile Data) › Cellular Data Options.
2. Turn Data Roaming on.
3. On arrival, cycle Aeroplane Mode to get connected.

Roaming APN Settings — SMARTY

SMARTY uses the same APN for both UK data and international roaming: smarty. 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 — SMARTY

Yes — SMARTY includes EU roaming in 71+ countries via Three's network.

Verify your destination is covered

It's worth double-checking, since plans vary rather than assuming Three's full "Go Roam" list applies to you. Open the SMARTY app, 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 help.smarty.co.uk (online chat only — no phone support) can confirm before departure if you're unsure.

Countries Smarty Roaming Covers

SMARTY 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.

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

Smarty Roaming Data Caps & Charges

A clear picture of roaming costs helps you avoid surprise bills. Here's how charges usually work on SMARTY:

• Even in covered roaming zones, fair use limits may cap usable data on certain plans.
• Included zones use the normal UK data, calls and texts allowance, typically at no added cost.
• Data can stop outright or move to a paid top-up once the roaming cap is reached, depending on the plan.
• Travel past included roaming zones means standard rates, often much steeper — worth arranging an add-on beforehand.

Troubleshooting SMARTY Roaming

1. Confirm the destination is on the plan's covered list, since coverage varies.
2. Turn on data roaming via Settings › Mobile Networks, as most devices ship with it disabled.
3. Verify APN settings — check APN is still set to smarty and has not been replaced by a local carrier profile.
4. A quick 30-second Aeroplane Mode cycle triggers the phone to re-scan for networks.
5. Restart your phone after arriving to register on a local SMARTY partner network.
6. Check signal strength — in remote areas or certain countries, SMARTY may have limited partner coverage.
7. Try manual network selection: Settings › Mobile Networks › Network Operators. Search for networks and select a SMARTY partner manually.
8. Contact SMARTY support: 0333 777 1777.
