Why choose iD Mobile?

Bill capping and data rollover

iD Mobile plans let you cap your monthly spend so you can't run up unexpected charges. Unused data is automatically rolled over to next month too, so you get a second chance to use it.

Nationwide coverage

iD Mobile is a subsidiary of retail giant Carphone Warehouse. Its service is based on Three’s network infrastructure, so is able to offer 98% nationwide coverage.

Wi-Fi calling

Got a dead spot in your home where your phone signal dips? No problem. On iD you can use your Wi-Fi signal to keep the conversation flowing loud and clear, wherever you are at home.


iD's coverage spans 99.8% of the UK outdoor population, so the network has you covered.


iD Mobile's service is based on Three’s network with an average connection speed of 22.55Mbps. That's according to a network speed survey conducted by OpenSignal (1 Dec 2017 - 28 Feb 2018)

And with 5G now on iD, you can enjoy even faster data speeds, better connectivity in busy places and less buffering when watching films or making video calls. With average speeds up to 9x faster than 4G, you can download apps and stream high-res movies in seconds.

*5G compatible device and 5G coverage required.


All 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.

Inclusive roaming in 50 locations

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.
