iD Mobile plans explained

Ironically, you may not recognise iD - it’s a relatively new mobile network. But you’ll definitely be able to identify the anachronistically-named company it comes from: Carphone Warehouse.

Despite its relative youth, iD's already making an impact by offering some of the most affordable 4G plans around. Everything's built around value, flexibility and simplicity - it's easy to find a plan that suits you, and the network makes sure it doesn't hide behind jargon and is upfront about tariffs and extra costs.

That focus on simplicity means that it doesn't come with much in the way of bells and whistles - no cool extras like priority tickets, or free subscriptions to Netflix here - but if you're just interested in a network that makes it easy, that might not matter.

iD Mobile plans and tariffs

There are loads of iD Mobile plans available, some with a phone included and some SIM-only. Each offers a set amount of inclusive minutes, texts and data per month, from 500MB - suitable for light use like checking email and instant messages - all the way up to a hefty 10GB - enough to download some apps and stream a few movies and TV shows via mobile internet each month.

These types of plan are available both pay monthly with a phone, and as SIM-only.

All its plans come with a few clever features too:

  • Data Rollover, which lets you roll any unused data allowance over to the next month.
  • Capping, which lets you put a limit on how much you can spend on your plan each month, basically eliminating bill shock. It's adjustable and can be as low as £5.
  • Inclusive roaming in the EU and EEA.
  • You can also get a pay-as-you-go SIM if that's more your jam.

What phones can you get from iD Mobile?

iD Mobile has a decent selection of handsets from all the big names, including iPhones, Samsungs, HTCs, LGs, Sonys, Huaweis, and Motorolas.

There's a nice balance between high-end wonder-phones like the ultra-sexy HTC 10 and Samsung Galaxy S8, and quality low-priced handsets like the Alcatel Pixi.

iD Mobile 4G coverage

iD Mobile shares Three's network, which reaches more than 97% of the population with 3G services. Unfortunately, Three doesn't have the widest 4G coverage, with the faster mobile internet mostly found in and around cities at present. Still, you're almost certain to be able to connect.

If you have an iD plan, you'll connect to 4G automatically if you're in a coverage area, otherwise you'll use 3G. Check out our guide for more on mobile coverage.

What's good about iD Mobile?

  • Affordable, flexible 4G plans
  • Simple tariffs that don't hide behind jargon
  • Can roll your data over to the next month
  • Can set a cap from £5 so you can't overspend
  • One month contract terms available
  • Good range of phones available, including iPhone 7, Samsung Galaxy S8, and Google Pixel

What's bad about the iD Mobile network?

  • Weaker 4G coverage than some other networks, particularly EE
  • Allowances aren't the highest on the market
  • Not much in the way of perks or extras compared to EE, O2 and Vodafone


  1. How do I check network coverage?

    All networks have a coverage checker on their websites, so check there as your first port of call. These give a good indication of whether you will get a signal in different parts of the country. It’s worth noting that these offer a simplified view of coverage and aren't necessarily 100% accurate, but they give you a good indication all the same.

  2. If I switch, can I keep my mobile number?

    Yes you can. All you have to do is ask your old network for your Porting Authorisation Code (PAC) before your contract is up. Then give the PAC - likely a nine-digit number - to your new provider and you’ll usually be able to use your old number within a working day.

  3. How do I switch mobile contracts?

    First, pick a new mobile contract by comparing different packages on our site, and click through to sign up to one that looks good.

    Then, simply contact your current provider to cancel, and switch to the new contract. Providers should walk you through the process when you sign up.

  4. Can I use my mobile phone abroad?

    It is possible to use your phone abroad, but before you can do so you may have to activate roaming with your network operator. Different countries incur different charges, but your operator should send you a message about roaming prices upon your arrival. And remember, unlike at home, you may be charged for receiving calls as well as making them.

    If you're travelling within the EU, you can use your usual monthly allowance at no extra cost - whatever network you're with.
