Whether Three charges you to use your phone abroad isn't a simple yes or no — it genuinely depends on your specific plan and when you joined. Here's exactly how it works.
The short answer
Three's roaming system, called Go Roam, splits destinations into three bands: Go Roam in Europe (49 destinations), Go Roam Around the World (a further 22), and Go Roam Around the World Extra (a further 92, bringing the total to over 160). Whether you roam free in any given destination depends entirely on which plan tier you're on:
- Value plans get free roaming in the 49 Go Roam in Europe destinations only.
- Complete plans get free roaming across all 160+ Go Roam destinations worldwide.
- Pay As You Go customers get free roaming in the Europe destinations too.
If the country you're visiting isn't covered by your specific plan tier, you'll be charged a daily rate to unlock your UK calls, texts, and up to 12GB of data for 24 hours.
Why the daily charge varies so much
Three's daily roaming charges have changed more than once, and the exact rate you'd pay depends on when you joined or upgraded your plan — customers who joined before October 2021 have historically been protected from these charges entirely, while more recent joiners pay increasing rates that Three has revised upward on more than one occasion, with further annual increases built in. Given how frequently these figures shift, checking Three's own roaming page for your specific plan and join date is more reliable than any fixed number quoted elsewhere, including here.
What you actually get once unlocked
Once your roaming is active — either because your plan includes the destination for free, or because you've paid the daily charge — you get:
- Up to 12GB of your UK data allowance per month, at no separate cost within that limit
- Unlimited calls and texts to standard UK landline and mobile numbers, with no fair use cap on this specifically
- The ability to call between different Go Roam destinations, not just back to the UK
- Access to voicemail and Three customer service as normal
For the Around the World bands specifically, there's a fair use policy of 3,000 minutes and 5,000 texts per month on top of the data allowance, which is generous enough that most travellers won't come close to hitting it.
Buying a Go Roam pass instead of paying daily
If you don't have inclusive roaming for a particular destination, you can buy a Go Roam pass in advance or while you're already abroad, which can work out cheaper than the standard daily rate depending on how many days you're travelling for. You can stack multiple passes if you're away for an extended trip.
Need more than 12GB? Data Passport
If you're planning to use significantly more data than the 12GB Go Roam allowance — heavy video calling, streaming, or working remotely — Three also offers a Data Passport add-on, giving unlimited data for a fixed daily fee across a wide range of destinations. This is worth considering if you know in advance that 12GB won't be enough, rather than risking a slower connection once you hit the fair use limit.
Checking if your device is ready before you travel
Three recommends checking via the Three app or My3 account that your specific device is roaming-ready before you fly, since this can flag any account-level issues (like an unpaid balance or account restriction) that would block roaming regardless of your plan's coverage.
How this compares to other UK networks
Roaming policies vary meaningfully across UK networks, and Three has historically been positioned as one of the more traveller-friendly options given how many destinations Go Roam covers on its higher-tier plans. We compare SIM-only deals with EU and international roaming here if you're deciding between networks specifically based on how they handle travel.
If you're switching networks before a trip
If you're considering switching to a different network specifically for better roaming coverage, our guide to switching SIM providers covers the process, and our guide to what a PAC code actually does explains how to keep your number when you move.
Before you travel
If you're due a phone upgrade before your trip, it's worth sorting it out beforehand. Compare refurbished phones here, or if you're upgrading and want to know what your current phone is worth, get a live trade-in price here first.
The bottom line
Three doesn't have one single answer to "will I be charged abroad" — it depends entirely on your plan tier and which destination you're visiting. Value plan customers get Europe free; Complete plan customers get the full 160+ destination list free; everyone else pays a daily rate that's increased over time and varies by join date. Check Three's own roaming page for your exact plan before you fly, since it's the only source that reflects current, plan-specific rates accurately.
