You can access the Go Roam Around The World offer on Three’s SIM-only deals, Pay Monthly contracts and Pay As You Go plans.

Plans with Go Roam

The easiest way to get access to the Go Roam offer is by getting a SIM-only deal from Three.

You’ll get access to the complete Go Roam Around The World offer on all of the following SIM cards from £5/month:

All of Three’s SIM-only deals include 5G at no extra cost, along with personal hotspot usage in Europe.

In our opinion, the inclusion of Go Roam on all of Three’s SIM-only plans is a significant benefit compared to other UK mobile networks. Other major networks like EE and Vodafone have announced that they’ll start charging for international roaming in Europe during 2022 (except from on their most expensive plans).

International Coverage

In most Go Roam countries, Three now offers 3G and 4G coverage when roaming. This is provided by a number of local partner mobile networks. Three does not offer any 5G roaming at present.

Unfortunately, Three stopped publishing the full list of their partner mobile networks during 2020. The following table shows their international coverage as published in 2020, but things may have changed since then:

Limitations & Restrictions

With the Go Roam offer on Three, there are five key limitations worth being aware:

  1. Tethering and personal hotspot are chargeable when you’re travelling to a Go Roam country outside Europe.
  2. Data usage is limited to 12GB per month in Go Roam countries.
  3. Inclusive minutes and texts can only be used for contacting UK-based numbers, as well as EU-based numbers when travelling in Europe.
  4. There are restrictions in place so you can’t use the service exclusively abroad.
  5. Although 4G coverage is now available in most Go Roam countries, download speeds might be slower when you’re abroad.

In the following section, we’ll discuss each of these limitations in more detail.

Tethering Is Chargeable Outside Europe

Inside the UK, you’ll normally be able to use tethering or personal hotspot to share your data allowance with other devices (e.g. with your laptop or tablet).

If you’re travelling to a Go Roam country in Europe, tethering can be used as normal when you’re abroad. You can tether from your normal plan allowance, or at a rate of 1p/MB or 5p/MB when your allowances run out (the out-of-allowance charge will depend on your plan).

If you’re travelling outside Europe, tethering is prohibited unless you buy a £5 per day Data Passport add-on. There’s more information about this on Three’s website:

You can’t use your phone as a Personal Hotspot in our Go Roam Around the World destinations.

If you want to use your device as a Personal Hotspot [in a Go Roam Around The World destination] or to stream or connect to Virtual Private Networks (VPNs) at faster speeds, you can choose to purchase our Data Passport, which gives you unlimited, unrestricted data to use until midnight (UK time) on the day of purchase for just £5. You can use this unlimited data allowance to tether or stream to your heart’s content and connect to VPNs.

Fair Usage Policy

When using the Go Roam service, there’s a fair usage limit of 12GB per month.

If you use more than 12GB of data in Europe during one month, you’ll be surcharged for further usage at the rate of 0.3p/MB. You’ll never lose access to your mobile phone service for exceeding the fair usage policy in Europe.

When using Go Roam outside Europe, there’s a fair usage policy of 3000 minutes, 5000 texts and 12GB of data. Outside Europe, this is a hard limit. If you exceed it, your data usage abroad will be blocked for the rest of the monthly billing period. If you exceed the fair usage limit outside Europe twice in a rolling 12-month period, Three says they reserve the right to suspend international roaming on your account.

International Calls Are Not Included

When you’re abroad, your allowance of UK minutes and texts can only be used for contacting other UK-based phone numbers (phone numbers beginning with +44). This means you can call and text your friends and family back home in the UK, as well as fellow holidaymakers who are also using a UK-based SIM card.

If you’re using Go Roam in Europe, Three will also allow you to call and text other phone numbers based in the EU using your allowance. This might include phone calls to your hotel, a local taxi firm or more.

If you’re using the Go Roam offer outside Europe, you’ll only be able to call and text other UK-based phone numbers with your allowance. This doesn’t include phone numbers in the country you’re travelling in. For instance, if you’re travelling in the US, you won’t be able to call US-based phone numbers with your allowance. Instead, you’ll need to pay up to £1.40 per minute when you make these calls.

Living Abroad

The Go Roam offer is designed for UK residents who are making a trip abroad. It isn’t designed for people who live abroad for an extended amount of time.

When using Go Roam in Europe, Three will look at the balance of your usage over a rolling 4-month period. If over the 4-month period, you spend the majority of your time abroad in Europe and if you also use more of your allowances there than you do in the UK, Three reserves the right to add a surcharge to your plan. The surcharge is up to 3p/minute, 1p/text and 0.3p/MB (or 10p/minute, 10p/text and 5p/MB for New Pay As You Go customers). You’ll be given at least two weeks notice before a surcharge is applied to your account.

When using Go Roam outside of Europe, a different limit applies to your usage there. Here, Three will look at the number of “complete months” you spend abroad in a Go Roam Around The World country. By complete months, this means you’ve spent the entire month abroad in a Go Roam country. If you’ve also used your phone inside the UK or in a non-Go Roam country, it will not count as a complete month towards your limit. Customers mustn’t spend more than two complete months abroad per year in a Go Roam Around The World country:

Go Roam is intended for our UK customers who are UK residents or have stable links with the UK (e.g. full-time employment or study in the UK) who are visiting one of the destinations for short periods, like holidays or business trips. It isn’t designed for people who live abroad or stay for extended periods.

If you roam exclusively in a Go Roam Around the World destination for any two complete months in a rolling 12-month period, we may suspend International Roaming on your account, meaning you will no longer be able to use your phone or device abroad. Of course, we will let you know in advance if this is likely to happen. If you spend a full month abroad but some of that time is spent in a destination that isn’t included in Go Roam, the restriction won’t apply.

These restrictions are listed in Three’s price guide.

Data Speeds

Historically, Three has only provided 2G and 3G coverage to customers who are roaming abroad. However, this has recently changed and 4G coverage is now available in the majority of Go Roam destinations.

Despite the ability to access 4G coverage, download speeds may still be slower when you’re abroad in a Go Roam country. For instance, while streaming and Virtual Private Network (VPN) services should work when abroad, the experience may be “slower” than it is in the UK:

You’ll be able to stream and connect to Virtual Private Networks (VPNs) while in a Feel At Home destination, but both of these may be slower than they are in the UK.

If you’d like to access faster download speeds when abroad, you can buy Three’s £5/day Data Passport add-on. This gives you unrestricted speeds for streaming and VPN, along with the ability to use your phone as a Personal Hotspot outside Europe.

Data Passport

If you have a Three Pay Monthly plan, you can buy a £5 per day Data Passport add-on. This gives you unlimited data for use in 89 destinations without any restrictions on download speed or tethering.

There are three reasons why you might want to buy a Data Passport add-on:

  1. Data Passport can be used in 89 destinations, including a number of countries that are not included in Go Roam. The £5 per day Data Passport add-on gives you unlimited data for use in the following countries, in addition to the Go Roam countries:

    Data Passport Countries (£5 per day):

    • Azerbaijan
    • Canada
    • Malaysia
    • Mexico
    • Moldova
    • Myanmar
    • Pakistan
    • Russia
    • Saudi Arabia
    • South Korea
    • Taiwan
    • Thailand
    • Tunisia
    • Turkey
    • United Arab Emirates

    plus all Go Roam countries and the UK

  2. Data Passport gives you unrestricted usage in Go Roam destinations. If you add the £5/day Data Passport add-on, you’ll get unrestricted speeds for streaming video and music when abroad. You’ll also be able to use your phone as a hotspot and will be able to connect to Virtual Private Networks (VPNs).
  3. Data Passport can be used when you run out of data on your plan. You can buy a Data Passport for additional data if you run out of your core data allowances when abroad.

For more information about Data Passport, see Three’s official website.

Keeping Your Phone Number

If you’re switching to Three so you can take advantage of their Go Roam offer, it’s a straightforward process to keep your current phone number.

Start by asking your current mobile network to provide you with a PAC Code. You can get one through your mobile network’s website or app, or by texting PAC to 65075. Once you have it, you can order your new phone or SIM card from Three’s website.

Once your new phone or SIM card arrives, fill out this form on Three’s website. After you submit your PAC Code, Three will schedule the transfer of your phone number (normally for the next working day). In the meantime, you’ll continue receiving a service from your old mobile network.

For step-by-step instructions on transferring a phone number to Three, please select your current mobile network:

PAC Code Finder: Transfer Your Phone Number to Three

Select your current mobile network:

  More Options

If you’re only using Three on a temporary basis, it’s best to set up call forwarding from your current mobile network instead. If you transfer your phone number using a PAC Code, the account on your old mobile network will be closed automatically.

We'd love to hear your thoughts and any questions you may have. So far, we've received 568 comments from readers. You can add your own comment here.

  • Three roaming speeds are awful. You will get super slow data connection and throttled data service to a barely usable level on all three Go Roam partner networks.
    For example Yoigo in spain, or Wind italy – can just about use whatsapp for chats, no chance to stream or even load most websites – it just sits spinning. Same on most roaming networks that are advertised as ‘free’ but in reality are unusable.
    When I complain to three they said – ‘we are unable to control roaming networks’ which is just nonsense. They have setup a throttled and barely usable service level in the interconnect agreements with these networks, so customers think you have a roaming service but its worthless..

  • Hi Ken, I wonder how a “complete” month is counted. If I don’t stay exclusively in a Go Roam country for a complete month, then I am not caught by the restriction of “over-staying” abroad. For example, staying in the US for 3 weeks, visiting Canada (a non-Go Roam country) for 1 week, and then visiting the US again for 10 days before returning to the UK. Is this not considered as a “complete month”, even though I have been in the US for 31 days, and in fact outside the UK for more than 5 weeks in total?

    • Hi Lewis,
      Thanks for your comment. Sadly, as far as I know, Three have never fully defined what they mean by a ‘complete month’ (i.e. whether it’s based on 30 consecutive days, or based on calendar months instead). However, spending some time in a non-Go Roam country mean you’re not spending the ‘complete month’ in a Go Roam country, with either definition. Therefore, based on what you’re saying about spending 3 weeks in the USA, followed by 10 days in Canada, this shouldn’t count as a complete month under either definition (even if you were to later return to the USA).
      Hope this helps,
      Ken
