All customers on iD Mobile SIM-only and mobile phone plans allow you to use your UK monthly allowances of data, calls and texts in 50 locations in Europe and beyond for no extra charge.

Data rollover

iD Mobile allows customers to rollover unused data from one to another for free, so you've got a second chance to use it. Any data that's unused from last month is rolled over automatically.

Bill capping

Customers can set spending limits for monthly bills for the UK and overseas, to avoid being hit with unexpected charges.

A buffer of up to £5 extra is available, however, which they can use when they need an extra allowance.

Caps can be adjusted with the iD Mobile app.


Launched in 2015, iD Mobile promised consumers “capped plans for the lowest price on the market” and roaming plans that it claims “cover more European countries than anyone else”.

It uses Three's network to ensure customers get nationwide coverage and fast speeds.

Early upgrades

iD Mobile doesn't offer a mid-contract handset upgrade scheme that's comparable to Tesco Mobile's Anytime Upgrade Flex or O2 Refresh. However, customers who renew contracts are often able to get a new phone before their existing contract ends.


### How do I unlock my iD Mobile phone?

If your iD phone is locked, you have to wait for 6 months and have paid any outstanding balance before the network will unlock the device for you.

Why is iD Mobile so cheap?

You can get a cheap iD Mobile deal across a range of handsets, including the latest iPhone range of smartphones. Powered by Three’s network, iD’s price doesn’t mean it’s lacking in quality.

How do I cancel my iD Mobile contract?

If you’ve come to the end of your iD contract, you just need to ring iD Mobile and inform them you’d like to switch to a new deal. You can then negotiate new terms or move to another network.

Are iD mobile phones unlocked?

Mobile phones are sometimes locked to iD, but you can get them unlocked provided you’ve been on your deal for 6 months and have paid off your balance.
