Items

Inadvertent roaming

Inadvertent roaming – also known as accidental roaming – is when your device accidentally connects to a network in another destination. This can happen if:

  • You live or travel near an international border, where your device may connect to a network in different country
  • You live or travel near a coastline, where your device may connect to a maritime network
  • You’re on a plane, where your device may connect to an airline network

Connecting to another network may mean you’re charged higher roaming rates. If you connect to a network in a new destination, we’ll send you a text explaining any charges you can expect there.

If you’ve opted out of these notifications, you can reactivate them by texting START to 330.

We’ll also let you know if any roaming charges are incurred, and when any Go Roam Passes or Data Passports are activated and end.

To avoid inadvertent roaming, you can:
  • Review your credit limit on your My3 account
  • Switch off Data Roaming
  • Manually select the network for the country you’re in. If you do this, you’ll need to manually change your network each time you visit a new destination 

You can find out how to switch off Data Roaming or manually select a network by searching for your device on our device support page.

Inadvertent roaming in Northern Ireland

If you live close to the Northern Ireland border, your device may accidentally connect to a network in the Republic of Ireland. 

To help you avoid any accidental charges, we’ve excluded the Republic of Ireland from our monthly fair use limit of 12GB. So, you can use your data without going over that limit. 

There are also no fair use limits for making calls or sending texts while roaming in a Go Roam in Europe destination. The Republic of Ireland is also excluded from the daily roaming charge.

Before you go

Keep your account at your fingertips wherever you go. 

Check your balance, top up, and get all the Data Packs and Add-ons you may need. 

Download the Three app

To use data abroad, you must have data roaming switched on in your device settings. If it’s switched off, you’ll only be able to call and text.

Manage roaming settings

Some networks abroad are switching off their 2G and 3G coverage, so having a 4G device is more important than ever. 

To stay connected while you’re abroad, you’ll need a 4G device with 4G calling or VoLTE enabled in your settings. 

Use our device support page to check if our device is compatible with 4G calling.
