Roaming & calling abroad

How do I activate Go Roam?

Go Roam activates automatically when you arrive in a Go Roam destination and use your phone (either by making a call, text or using data – this includes your Apps working in the background). You'll receive a text with the roaming charges for that destination.

For specific charges, search for your destination on our roaming page.

What are the roaming fair use policies? 

In Go Roam destinations, whether you pay a daily roaming charge (this is triggered automatically)  or buy a Go Roam Pass, your available usage abroad comes from your monthly UK allowance. If you have a UK data allowance greater than 12GB, you can use up to 12GB of data in a billing month in our Go Roam Destinations. If you use 12GB and still have remaining UK data allowance available, you can continue to use your data, but this is subject to a surcharge;  Within a billing month, both your usage in the UK and abroad will go towards your total usage i.e. if you have 20GB data and have already used 10GB in the UK, you’ll have 10GB to use abroad.

Go Roam in Europe

  • Calls and texts: Use your UK plan allowance for calls and texts within Go Roam in Europe destinations, or back to UK standard landline or mobile numbers (including voicemail).
  • Data: Up to 12GB per billing month from your UK allowance.  Surcharges apply if you go over this. 

Go Roam Around the World and Go Roam Around the World Extra:

  • Calls and texts: Up to 5,000 texts and 3,000 minutes per month to UK standard landline or mobile numbers (including voicemail).
  • Data: Up to 12GB per billing month from your UK allowance. Surcharges apply if you go over this. 

For Enterprise Roaming plans, check your specific allowance details.

What if I’m travelling to a non-Go Roam destination? 

In non-Go Roam destinations, you can't use your UK allowances. You'll be charged standard roaming rates per minute/text/MB of data, which vary by country. Use our Destination checker to find your costs.

How do Go Roam Passes work? 

A Go Roam Pass activates on first use in a Go Roam destination, first use includes calls, texts, and any data usage, including background app updates. You can use it for the specified number of days, which don't need to be consecutive. Leftover days stay on your account for future trips.

You'll get a text when your pass is activated and another when it ends. Unused passes don't expire unless you change your plan, or upgrade. To see how many days left you have on a pass, log in to your Three Business account.

Can I buy more than one Go Roam pass?

Yes, you can buy multiple Go Roam Passes. They will be used in the order purchased if they are the same type.

You can also buy different types of passes. If you have both Go Roam in Europe and Go Roam Around the World passes, the Go Roam in Europe pass will be used first, if you are roaming in a Go Roam in Europe destination.

Is calling or texting to international numbers included in Go Roam plans?

In our Go Roam in Europe destinations, you can make calls both back to the UK and to other standard landline and mobile numbers in those Go Roam in Europe Destinations.

Our other plans do not include international calls or texts, only back to the UK and UK mobiles.  Surcharges will be applied if you ring/text any other type of number. Please see the destination tool for more pricing information.

I’m an Adapt customer - do I have to pay a daily Go Roam charge?

For Adapt plans:

  • No daily roaming charge for Go Roam in Europe destinations. Fair use policies still apply.

The same Daily Roaming Charges and fair use policies apply to all other destinations;

  • £5 daily charge to unlock your UK allowance for 24hours in Go Roam Around the World destinations. Includes VAT where applicable and is per SIM.

I’m visiting a destination that is now in Go Roam Around the World Extra with a daily roaming charge, when did this change and what does it mean?

Go Roam Around the World Extra launched on 26 June 2024.  This new band in our Go Roam product allows you to access your UK allowance* in 92 new destinations for a daily roaming charge of £7.

Prior to 26 June, 2024, you would have been charged £/p per MB, minute, text rates for those 92 destinations.

If you joined/upgraded before 1 October 2021 we won't apply this daily roaming charge and you will continue to pay the £/p per MB, minute, text rates.  To understand all your out-of-bundle charges, see our Roaming Price Guide.
