Uswitch services are provided at no cost to you, but we may receive a commission from the companies we refer you to. If a deal is "promoted" on Uswitch's tables, then it has been lent additional visibility as a result of us securing exclusivity on a great deal, or a commercial agreement to showcase what we believe to be market-leading value to consumers.

Until 2024, many mobile networks have increased contract prices in line with inflation. Starting in January 2025, Ofcom will introduce a ban on inflation-linked price hikes for new contracts. Future price changes will need to be set and fully disclosed in pounds and pence.
iD Mobile is a great pick for handset contracts, especially if you want more for less. With competitive prices, data rollover, and free EU roaming, it packs in plenty of perks. You’ll also get handy extras like bill capping, WiFi calling, and 99% UK 5G coverage, so you’re sorted whether you’re streaming at home or scrolling abroad.
iD Mobile offers some of the cheapest handset contracts and SIM only deals, making it ideal for budget-conscious customers.
Use your phone in 50 European destinations without extra charges — perfect for holidays or working abroad.
Enjoy data rollover, bill capping, Wi-Fi calling, and 5G at no extra cost and all designed to give you more control and better value.
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.
iD Mobile is a subsidiary of retail giant Carphone Warehouse. Its service is based on Three’s network infrastructure, so is able to offer 99% nationwide coverage.
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 Mobile runs on the Three network, delivering solid speeds and wide coverage across the UK. Recent reports show average 4G speeds of around 22 Mbps, while 5G speeds average over 200 Mbps, giving you a much faster and smoother experience for streaming, gaming, and downloading. With 5G now covering 99.8% of the UK population, iD Mobile users can expect strong performance in most areas — all at no extra cost, as 5G is included with every plan (just make sure you’ve got a 5G-ready device and coverage in your area).
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.
However, data roaming in the EU has a 30 GB cap, after which additional charges will apply.

iD Mobile offers a selection of tariffs, all of which offer these benefits:
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.
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.
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.
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.
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.
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.
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.
