Data charges

Update for iOS users

Accessing zero-rated websites will use your data allowance if you’re using iCloud Private Relay.

If you have Unlimited data included in your plan or you’re using one of our Unlimited Data Add-ons, good news - we’ll never charge you more than your monthly bill for using data.

If you’re not on an Unlimited plan, you don’t need to worry about going over your allowance accidentally. Once you’ve used up your monthly data, you’ll need to buy an Add-on or change price plan to use more. We’ve done this so you won’t spend more than you mean to.

We’ll text you when you’ve used 80% and 100% of your allowance, so you shouldn’t run out unexpectedly.

Older or Pay As You Go plans won’t have this cap, so you’ll need to keep an eye on your usage. You can check your allowance on the Three app or in your My3 account. If you go over your allowance, you can check our price guide to see what you’ll be charged.

Note: This doesn't apply to Mobile Broadband plans.

Out of Bundle charges

Our prices for anything not included in your allowance are listed here. You shouldn’t be charged for data outside of your allowance because of the way our plans are designed. However, if you want to check our data prices, you can check your price guide.

The table below shows any charges for out of allowance activity. This includes minutes outside or over your allowance, and international calls. International call charges apply when you call another country from the UK and are separate to Go Roam charges.

Data charges abroad

For Pay Monthly customers who joined or upgraded on or after 1 October 2021, there’s a daily roaming charge to unlock your UK allowances for 24 hours in Go Roam destinations. The charge starts when you use any of your allowances in a Go Roam destination including making calls, sending texts, or using data. It’s £2 in Go Roam in Europe, £5 in Go Roam Around the World, and £7 in Go Roam Around the World Extra destinations. 

This will not affect Pay Monthly customers whose plan started before 1 October 2021, or Pay As You Go customers. Please note: Go Roam Around the World Extra is not available on these plans.

To help you manage your roaming costs when you’re travelling, we’ll text you information about roaming rates for each country you visit. We’ve also set up a worldwide data roaming limit of £45 plus VAT to stop you spending too much. If you’d prefer you can have this limit removed or changed by contacting Three Customer Services.

If you’re not in a Go Roam destination or don’t have Go Roam, you’ll be charged our standard roaming rates. You can find out these rates on our destination pages.

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.
