Three Around the World Roaming: 163 Destinations Explained for Business
Three Around the World Roaming: 163 Destinations Explained for Business
Last updated: April 2026
Most UK business mobile contracts treat international roaming as an afterthought. The headline plan covers UK use, then there is a footnote saying "extra charges apply for use abroad," and you find out the actual cost only when you get the bill. For a business with people who genuinely travel, this is a nightmare. You either pay random daily fees that add up unpredictably, or you spend half a day on hold trying to add a roaming bolt-on before someone catches a plane.
Three's Business Inclusive Roaming structure is the closest thing the UK market has to a sensible solution to this. Three tiers, 163 destinations between them, no daily charges if you pick the right plan, and the flexibility to mix and match across SIMs so only the people who actually travel pay for it. It is also the most generous worldwide product from any UK network in 2026 by a noticeable margin.
The trade-off is that you have to understand which tier covers which countries, and you have to pick the right one upfront. Here is the proper version.
The Three Tiers in One Place
Three Inclusive Roaming has three tiers. They are cumulative, so each higher tier includes everything in the lower tiers plus more destinations.
Inclusive Roaming Go Roam in Europe — 49 European destinations.
Inclusive Roaming Go Roam Around the World — 71 destinations total. Includes the 49 European destinations plus 22 worldwide destinations.
Inclusive Roaming Go Roam Around the World Extra — 163 destinations total. Includes the previous 71 plus another 92 worldwide destinations.
Each tier is a separate add-on to your monthly tariff. You add it to specific SIMs, not the whole account, so you only pay for it on the lines that travel.
When you are on an Inclusive plan, the daily roaming charge does not apply. You travel, you use your phone normally (subject to the data cap and fair-use limits), and your bill stays the same. When you are NOT on an Inclusive plan, you pay daily charges of £2 (Europe), £5 (Around the World) or £7 (Around the World Extra) per day of use.
Tier 1: Go Roam in Europe (49 Destinations)
The smallest and cheapest tier. Covers all of the EU plus the obvious additions.
The full list:
Aland Islands, Austria, Azores, Balearic Islands, Belgium, Bulgaria, Canary Islands, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, French Guiana, Germany, Gibraltar, Greece, Guadeloupe, Guernsey, Hungary, Iceland, Ireland, Isle of Man, Italy, Jersey, Latvia, Liechtenstein, Lithuania, Luxembourg, Madeira, Malta, Martinique, Mayotte, Netherlands, Norway, Poland, Portugal, Reunion, Romania, Saint Barthelemy, Saint Martin, San Marino, Slovakia, Slovenia, Spain, Sweden, Switzerland, Vatican City.
What is included on the Inclusive plan:
- Unlimited minutes and texts to other Go Roam Europe destinations and back to the UK
- Up to 12 GB of data per month
- No daily roaming charge
- Republic of Ireland and Isle of Man have no fair-use limit
This is the right tier for any business whose travel is genuinely Europe-only. If your team flies to Paris, Berlin, Madrid, Amsterdam, Dublin, Lisbon or anywhere else on the list, this tier covers them. The 12 GB data cap is plenty for normal business use including emails, calls, browsing, and a moderate amount of file syncing.
Tier 2: Go Roam Around the World (71 Destinations)
Adds 22 worldwide destinations to the European 49. The added countries:
Australia, Brazil, Chile, Colombia, Costa Rica, El Salvador, Guatemala, Hong Kong, Indonesia, Israel, Macau, New Zealand, Nicaragua, Panama, Peru, Puerto Rico, Singapore, Sri Lanka, United States of America, Uruguay, US Virgin Islands, Vietnam.
The big one here is the United States. If your team has any US business travel at all, you need at least the Around the World tier. The other major adds are Australia, Hong Kong, Singapore, Brazil, and New Zealand, all of which are common UK business travel destinations.
What is included:
- Up to 3,000 voice minutes back to the UK
- Up to 5,000 texts back to the UK
- Up to 12 GB of data per month
- No daily roaming charge in any of the 71 destinations
The voice and text allowances are generous. You would have to spend nearly 50 hours on calls back to the UK to exhaust the 3,000-minute allowance, which is more than most travellers do in a month.
Tier 3: Go Roam Around the World Extra (163 Destinations)
The widest tier. Adds another 92 destinations to the previous 71. The full additional list includes most of Africa, the Middle East, the rest of Asia, and parts of Latin America that were not in the Around the World tier.
Notable additions: Canada, Japan, China, India, Saudi Arabia, United Arab Emirates, South Korea, Mexico, South Africa, Egypt, Turkey, Thailand, Malaysia, Argentina, and many others. The full 92 added destinations cover most countries you are realistically likely to visit on UK business.
What is included on the Inclusive plan:
- Same allowances as Around the World (3,000 mins, 5,000 texts, 12 GB data per month)
- No daily roaming charge in any of the 163 destinations
This is the right tier for businesses whose travel is genuinely worldwide. If you have people flying to multiple continents in a year, or if you have any travel at all to the major markets that are NOT in Around the World (Canada, Japan, India, China, the UAE), you want this tier.
Who Should Be on Which Tier
The way to think about it is: which tier covers everywhere your specific people actually travel, and is worth the additional monthly cost?
Tier 1 (Europe) is right for...
- Sales teams who only ever go to European clients
- Procurement teams attending European trade shows
- UK businesses with offices in EU countries (London/Paris, Manchester/Berlin, etc)
- Anyone doing European-only travel for the foreseeable future
Tier 2 (Around the World) is right for...
- Anyone with US travel, even occasional
- Businesses with operations in Australia, NZ, or East Asia (Singapore, HK)
- Sales teams covering Europe + US
- Travel between the UK and any of the 22 added destinations
Tier 3 (Around the World Extra) is right for...
- Anyone whose travel includes any of: Canada, Japan, India, China, the UAE, South Africa, Latin America, the Middle East, the rest of Africa
- Globally distributed sales teams
- C-suite who travel anywhere on short notice and need certainty
- Anyone who would rather pay slightly more per month than risk being in an uncovered destination
The Around the World Extra tier is the most generous worldwide business roaming product in the UK. O2 does not have an equivalent. Vodafone's structure is different and not as comprehensive at the same price point. EE charges extra per destination for many of the locations included here.
Mix and Match Across Your Business
This is the part that changes the maths. Three's tiers can be applied per SIM, so different people in your business can be on different roaming plans, or no roaming plan at all.
Real example. A 30-line business might end up with:
- 5 lines on Around the World Extra (the senior team and the two field engineers who go anywhere)
- 8 lines on Around the World (the sales team that mainly covers Europe + US)
- 6 lines on Europe (the account managers who only fly to European clients)
- 11 lines on no roaming (the office staff who never travel)
Total cost of roaming across the business: much lower than putting all 30 lines on the same Inclusive Around the World Extra plan. Each line gets the right level of coverage for what they actually do, and you do not pay for what nobody uses.
This is one of the things Three does better than O2. O2's Roam at Home approach is included on every line whether you need it or not. Three lets you put the right plan on the right SIM.
What About Destinations That Are NOT Included?
Even the 163-destination tier does not cover absolutely everywhere. There are countries that are not on any Three roaming list, mostly small island nations, conflict zones, and some Central Asian and African countries.
If you are travelling to a country that is not on the list:
- Check the destination list before you go. This is the single most important thing.
- Get a local SIM at the destination. Often the cheapest option for a multi-day trip.
- Use eSIM for travel data. Apps like Airalo sell prepaid eSIM data plans for almost everywhere, and you can buy them on demand.
- Use wi-fi calling at the hotel. If your phone is on UK wi-fi (via the hotel), calls and texts are treated as UK calls and texts, not roaming.
For occasional travel to one-off destinations, the local SIM or eSIM approach is almost always cheaper than negotiating a special roaming arrangement with Three.
Data Caps and Fair Use: The Small Print
A few things to keep in mind:
12 GB monthly cap per line on data. This applies on all three Inclusive Roaming tiers. Plenty for normal business use. Not enough for someone tethering a laptop all day. The fix is to add Data Passport for £6/day on heavy days.
60-day fair-use limit per 4-month rolling window. If a single SIM is roaming in any combination of Go Roam destinations for more than 60 days in any 4-month window, additional roaming charges may start to apply. This is to stop people using a UK SIM as a permanent foreign-resident SIM. You will be notified before extra charges hit.
Inclusive Roaming around the world voice and text allowances are 3,000 mins and 5,000 texts per month back to the UK. That is a lot, but if you blow through them you start paying out-of-bundle rates. Heavy callers should keep an eye on this.
Republic of Ireland and Isle of Man are special cases. No daily charge, no fair-use limit, on any plan.
How to Decide
The decision tree is reasonably simple:
- Where does each user actually travel? Make a list per person. Be honest about it.
- Match each person to the smallest tier that covers their actual destinations. Do not buy Around the World Extra for someone who only goes to France and Germany.
- Leave non-travelling staff on no roaming. Not every line needs an Inclusive plan.
- Add Data Passport on top for anyone who tethers heavily.
- Review at renewal. Travel patterns change. The right structure for 2026 might not be the right structure for 2027.

Frequently Asked Questions
Q: Can I add Inclusive Roaming to just some SIMs in my business account?
Yes. The plans are SIM-by-SIM. You only pay for roaming on the lines that travel.
Q: What happens if I exceed the 12 GB data cap abroad?
You start paying out-of-bundle data rates. To avoid this, add Data Passport (£6/day for unlimited data) on the days you expect heavy use.
Q: Can I use Inclusive Roaming in cruise ship terminals or on ferries?
Cruise ships and some ferries use satellite networks that are not covered by any Three roaming product. You will get an extra warning text if you connect to one of these. Avoid using your phone on cruise ships unless you have an explicit cruise add-on.
Q: What is the difference between "Around the World" and "Around the World Extra"?
Around the World covers 22 worldwide destinations including the US, Australia, Hong Kong, Singapore, and Brazil. Around the World Extra adds 92 more, including Canada, Japan, China, India, the UAE, and most of Africa, the Middle East, and Latin America.
Q: Do I have to sign a 24-month contract to get Inclusive Roaming?
The Inclusive Roaming plans are typically tied to 24-month tariffs. Check the specific plan terms before you commit.
Q: Can I switch from one tier to another mid-contract?
Yes, mid-cycle plan upgrades are usually allowed and we handle them on behalf of clients. Plan downgrades are sometimes restricted to renewal time.
Q: What about Switzerland, Norway, Iceland, Liechtenstein?
Those are in the Europe tier. They are included in all three Inclusive Roaming plans because all three tiers include the European 49.
Q: Does Inclusive Roaming work if I am on Three Business Dynamic?
Three Business Dynamic plans (for 25-250 SIM accounts) have their own roaming structure where Go Roam in Europe is included by default. Worldwide tiers can still be added.
Q: Is there a worldwide unlimited data option?
Yes. The Data Passport add-on gives unlimited data in 89 destinations for £6 per day. It stacks on top of any of the Inclusive Roaming tiers.
Q: How does this compare to O2, Vodafone, and EE?
Three's worldwide roaming structure is the most comprehensive in the UK. O2 has no equivalent worldwide tier. Vodafone and EE will quote you something on a corporate negotiation but the off-the-shelf prices are not as good. We have a full network roaming comparison if you want the side-by-side detail.
