Roaming abroad on Pay As You Go

Looking to use your Pay As You Go device abroad? From getting set up, to roaming allowances and how much it costs to use your phone abroad – here’s everything you need to know.

Before you travel

Check your data roaming settings

With data roaming switched off, you can still make calls and send texts.

Use your Pay As You Go SIM in the UK

To use your device abroad, your SIM needs to connect to our network in the UK before you travel. This is easy to do. Simply put your SIM into your phone, turn it on, and wait until it connects to our network or you see signal bars appear. Then you’re good to go.

Using Pay As You Go data in a Go Roam destination

If you’re travelling to any of our Go Roam in Europe or Go Roam Around the World destinations, you can use either your credit or a portion of your Data Pack or Add-on each month, at no extra cost. The amount of data you can use will depend on your Data Pack or Add-on.

Roaming with an Auto-renew Data Pack?

Set up a £10 Auto-renew Data Pack before 8 September 2024? You can still use up to 12GB of your data allowance while roaming in Go Roam in Europe or Go Roam Around the World destinations.

Set up a £10 Auto-renew Data Pack after 8 September 2024? You can use up to 6GB of your data allowance while roaming in Go Roam in Europe or Go Roam Around the World destinations. 

For all other Auto-renew Data Packs, the amount of data you can use while roaming in any Go Roam in Europe or Go Roam Around the World destinations will increase to the roaming allowances above. This will happen automatically, you don’t need to do anything.

The amount of data you can use depends on the price of your Auto-renew Data Pack as standard before any additional data or discounts are added. So, for example, a 10% discounted £13.50 Auto-renew Data Pack includes 12GB of Inclusive Roaming Allowance.

Calling and texting in a Go Roam destination

Go Roam in Europe
If you’ve got an active Data Pack or Add-on you can use all of your UK call and text allowances while roaming in a Go Roam in Europe destination. 

Go Roam Around the World
If you’re in a Go Roam Around the World destination, and have more than 3000 texts included in your allowance, you can send up to 3000 texts back to the UK each month.  

And if you’ve got more than 3000 minutes included in your allowance, you can use up to 3000 minutes to call standard UK landlines or mobile numbers each month.

Get yours on the Three app or by logging into My3. 

You can get more data with a Data Add-on. This will give you the boost of data you need until you can get a new Data Pack.  

You can’t buy a new Data Pack until your current one expires.

Checked your data roaming settings and used your Pay As You Go SIM in the UK? You can use your device in any Go Roam in Europe, Go Roam Around the World, or rest of the world destinations. 

Check your destination

The amount of data you can use depends on the price of your Auto-renew Data Pack as standard before any additional data or discounts are added. So, for example, a 10% discounted £13.50 Auto-renew Data Pack includes 12GB of Inclusive Roaming Allowance.

This means that you’re currently using an older type of Data Pack that gives you a 12GB inclusive roaming allowance for the first month.

From your next top up, you’ll automatically move to a new Data Pack and will be able to see your inclusive roaming allowance online. Until then, give us a call to check your inclusive roaming allowance.

Your Inclusive Roaming Allowance is considered part of your UK allowance. This means that once you consume your UK data allowance, you will no longer have any left to use while roaming. For example, if you have a Data Pack which gives you 30GB of data, and you have used 30GB in the UK before you travel, when you are abroad you will have 0GB of Inclusive Roaming Allowance left to use.
