Sim-only plans are available for 30 days, and 12 and 24 months, and include a range of pricing options. Choosing a pay-monthly plan allows you to select whether you want a supplied handset or prefer a Sim-only option.

Does iD Mobile increase its prices each year?

iD Mobile Sim-only contracts are not hit by costly inflation-based mid-contract price increases. For one-month rolling Sim contracts, you will be able to check what the price to renew is before the end of the month. If it does increase or is too expensive, you can simply switch to a different network with no penalty.

For 24-month handset contracts, iD Mobile increases its prices each year by £1.50 each April.

Does iD Mobile include free data roaming?

Yes, all iD Mobile Sim plans come with 30GB of free EU roaming. 

However, always check to see if the country you’re travelling to is covered before you leave. Some countries you may expect to be included, such as Switzerland or Turkey, are not. Use the iD Mobile roaming rate finder to see how much roaming might cost. 

It may be cheaper to buy a travel eSim for your trip, rather than relying on data add-ons or PAYG. Find out how to do this and what’s available in our guide to the best cheap eSims for mobile roaming abroad.
