iD Mobile roaming: the 50 free countries, the USA, and what everything else costs

How does iD Mobile roaming work?

Roaming comes as standard on every iD Mobile phone and SIM only plan. In iD's 50 Roam Free destinations, you use your UK minutes, texts and data as you would at home, at no extra cost. Before you go, iD says to turn roaming on in the iD Mobile app or in My Account online.

What is included in a Roam Free destination:

• your remaining UK data, up to 30GB;
• calls and texts to UK landlines and mobiles from your inclusive allowance;
• calls and texts to other Band 1 destinations from your allowance, and to the same country for Band 2 destinations;
• incoming calls and texts from anywhere.

iD blocks premium numbers (118 and 09), 084 and 087 numbers, and 080 numbers while you are roaming.

This is desk research from iD Mobile's own pages. We have not bought or tested an iD Mobile plan abroad.

Which are the iD Mobile free roaming countries?

We ran every country through iD's roaming checker on 10 November 2026. These 50 came back as Inclusive Roaming destinations:

Austria, Azerbaijan, the Azores, Belarus, Belgium, Bulgaria, the Canary Islands, Croatia, Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, French Guiana, Germany, Gibraltar, Greece, Guadeloupe, Guernsey, Hungary, Iceland, Ireland, the Isle of Man, Italy, Jersey, Kazakhstan, Latvia, Liechtenstein, Lithuania, Luxembourg, North Macedonia, Madeira, Malta, Martinique, Monaco, the Netherlands, Norway, Poland, Portugal, Réunion, Saint-Barthélemy, Saint-Martin, San Marino, Sint Maarten, Slovakia, Slovenia, Spain and Sweden.

Notice what is missing. Switzerland, Turkey, Albania, Serbia, Montenegro and Bosnia and Herzegovina are not free roaming destinations. All of them are on the paid Roam Beyond list.

Is there an iD Mobile fair usage policy for roaming?

Yes, and iD's own pages give two versions. The Roam Free page and SIM only page both say a 30GB data limit applies (or your allowance, if it is under 30GB). The fair usage page says that from 1 October 2024 and until further notice, all customers can use their full UK data allowance in Roam Free destinations, and that iD will tell customers when the 30GB limit is reinstated. The same page says the 30GB limit applies per month for customers who joined on or after 21 June 2023.

So on 10 November 2026 a promotion appeared to be lifting the limit, but iD can end it. If you need more than 30GB on a trip, check your account before you rely on it.

If you go over your allowance inside a Roam Free destination, these out-of-plan charges apply:

How much is iD Mobile roaming in the USA?

The USA is not a free destination. Without an add-on, the roaming checker showed these rates:

At 30p per MB, one gigabyte would cost about £307. Do not land in New York with data on and no add-on.

What is iD Mobile Roam Beyond?

Roam Beyond is iD's add-on for the 50 destinations outside its free list. The roaming checker listed these prices:

We read these prices on the checker's USA result, where iD presents them as its Roam Beyond prices; check your own destination in the app before you buy. iD says no extra eSIM download is needed, the data is at full speed with no caps, and 5G works in selected destinations. Buy it in the iD Mobile app or at my.idmobile.co.uk by choosing View Add-ons, then Roam Beyond, then your destination. iD suggests buying before you leave the UK, or keeping mobile data off on arrival until you are on Wi-Fi.

The Roam Beyond destinations our check returned were: Albania, Argentina, Australia, Bangladesh, Bosnia and Herzegovina, Cambodia, Canada, Chile, China, Colombia, Costa Rica, Egypt, the Faroe Islands, Ghana, Hong Kong, India, Indonesia, Japan, Jordan, Kosovo, Kuwait, Malaysia, Mexico, Moldova, Montenegro, Morocco, New Zealand, Nigeria, Pakistan, Panama, Peru, Puerto Rico, Qatar, Rwanda, Serbia, Singapore, South Africa, Sri Lanka, Switzerland, Taiwan, Thailand, Tunisia, Turkey, Uganda, the USA, Uruguay, Uzbekistan, Vietnam and Zambia. That is 49; iD says 50, so one may have been missed by the checker.

The add-ons are data only. Calls and texts in those countries are charged at the out-of-plan rates for that country.

What about iD Mobile on ships and planes?

Keep your phone in flight mode. Satellite networks on ferries, cruise ships and aircraft cost £6 a minute for calls, £1.20 a text and £9.60 per MB of data on iD Mobile.

Is a travel eSIM cheaper than iD Mobile roaming?

In the 50 free destinations, no. Your allowance already works there.

In Roam Beyond countries, it depends on the length of the trip. Here are the travel eSIM prices we verified on each seller's own site in August 2026:

For a long weekend in the USA, Roam Beyond is close to an eSIM on price and simpler, because nothing needs installing. For a week or more, the eSIMs last longer for similar money. For Turkey and Thailand, a travel eSIM costs roughly half the add-on or less, if the add-on price there matches the USA price. See our Turkey and Thailand guides, and the cheapest eSIM table.

If you add an eSIM, keep iD on for calls and texts and turn its data roaming off. Our data roaming guide shows where. For the plans themselves, see our iD Mobile SIM only guide.
