Three roaming: Go Roam daily charges, passes and the 12GB limit

How does Three roaming work?

Three roaming runs through Go Roam, which Three says covers over 160 destinations in three bands. In each, you use your UK minutes, texts and data, and pay one of three ways: roaming built into your plan, a daily charge, or a pass bought in advance. We read Three's Go Roam page and its Three Your Way price guide (dated 27 August 2026) on 10 November 2026. This is desk research; we have not roamed on Three.

Ireland and the Isle of Man carry no charge at all.

What are Three's daily roaming charges?

The daily charge depends on when you joined or upgraded:

Three applies the charge automatically the first time you use your allowance in a destination, a call, text or data, and it unlocks your allowance for 24 hours. On 24-month Lite 25GB and 120GB plans taken from 1 June 2025, Around the World is £5. Three says the post-December 2025 prices rise each 1 April, and its price guide sets that at January's CPI plus 3.9 percent. Customers from before October 2021 should check their own price guide.

Three's guide also sets a worldwide data roaming limit of £45 excluding VAT, which you can ask to change. If your Spend Cap is set too low to take the daily charge, Three says roaming may be blocked.

Which Three plans include roaming?

On current Three Your Way plans, Value includes Go Roam in Europe and Complete includes all three bands. Lite and Lite+ don't include any, so they pay the daily charge or buy a pass. Our 3 SIM only page sets out the tier prices.

Are Three roaming packages cheaper than the daily charge?

Yes, on almost any trip. Three sells Go Roam passes that unlock your allowance for a set number of days, starting on first use abroad:

A 7-day Europe pass is £12 against £19.25 in daily charges, and the Around the World Extra passes work out at £6 a day against £8. Three also sells Data Travel Passes, which give a separate data allowance without touching your UK plan: in Europe, 18GB for 7 days at £16, 40GB for 14 days at £33 or unlimited for one day at £7; worldwide, in 31 destinations including the USA, Canada and Turkey, 18GB for 7 days at £26 or 40GB for 14 days at £54.

What limits apply to Three roaming abroad?

Three's fair use lets you use up to 12GB of your UK data a month in any Go Roam destination, with a 0.3p per MB surcharge beyond that (Ireland excepted). In the two worldwide bands, calls are capped at 3,000 minutes and texts at 5,000. Three says Go Roam is for UK residents on short trips, and that if you roam for two complete months in a rolling 12, it may suspend roaming on your account.

Does Three pay as you go roaming cost the same?

No. Three says daily roaming charges don't apply on pay as you go, Around the World Extra isn't available, and your SIM must have been used for a call, text or data in the UK before roaming works. Its Go Roam page points to a separate pay as you go roaming page for allowances, and that page would not load when we tried, so we can't give its terms.

Three roaming against a travel eSIM

In Europe, Three roaming is cheap on a pass and free on Value or Complete. Airalo's verified Spain prices were $8 for 5GB over 7 days and $13 for 10GB (read on Airalo's site in August 2026). The 5GB plan undercuts the £12 pass, since a pound buys more than a dollar, but your Three number goes quiet for data, and the saving is a few pounds.

Long haul is where an eSIM pays:

Three roaming USA

£30 for a 7-day Around the World pass, or £56 in daily charges. Airalo's 10GB over 7 days was $21.50, Saily's 10GB over 30 days $22.99

Turkey or Thailand

£42 for 7 days. Airalo's 10GB over 7 days was $14.50 in Turkey and $10 in Thailand, and Nomad's 10GB over 30 days was $13 and $10

Japan

also £42 for 7 days. Airalo's 10GB over 7 days was $17

If you take an eSIM, keep the Three line on for calls and set its data roaming off; Three applies the daily charge on any use, and background data counts. Our data roaming guide shows the setting, and the cheapest eSIM page ranks plans by cost per gigabyte.

What would we do?

On Lite, buy a Europe pass for any trip of two days or more: two daily charges already come to £5.50, more than the 3-day pass. On any plan, go long-haul with a travel eSIM unless you need your UK number for calls all day. For comparison, see O2 roaming and Vodafone roaming.
