iD Mobile is the budget mobile network from the Carphone Warehouse, offering 4G price plans with coverage from Three.

In the UK, iD Mobile offers low-cost 4G price plans using coverage from the Three network. Launched by the Carphone Warehouse in 2015 as a lower-cost budget-orientated mobile network, iD Mobile competes with rivals networks including giffgaff, SMARTY, Talkmobile and VOXI.

At present, iD Mobile offers a range of price plans and bundles including SIM-only deals and Pay Monthly phones. You’ll get data rollover included on all Pay Monthly plans, along with bill capping and international roaming in 50 destinations at no extra cost.

In this article, we’ll review the iD Mobile network including the price plans available and the features of the network. We’ll then compare iD Mobile’s plans to those available on other networks before looking at the coverage you can expect on iD Mobile. Finally, we’ll look at how you can keep your current phone number when moving to the iD Mobile network.

iD Mobile Plans & Bundles

On iD Mobile, there’s currently three types of price plan available:

  • SIM Only Deals: This is a 1-month rolling contract with unlimited minutes, unlimited texts and an allowance of mobile data. SIM-only plans on iD Mobile start from £5/month. You’ll need to undergo a credit check when taking one of these plans from iD.
  • Pay Monthly Phones: This is a 24-month contract, with a new mobile phone included. You’ll pay more than you would on a SIM-only deal. This is because the monthly cost of your contract also includes the handset.
  • Pay As You Go SIM: iD Mobile has a range of a pre-paid bundles from £5/month with no need for a credit check. You won’t get features like data rollover when signing up for iD Mobile Pay As You Go.

SIM Only Deals

On iD Mobile, the most popular type of price plan are SIM-only deals. These start from £5/month.

All of the iD Mobile SIM cards are available on a one-month rolling basis and include unlimited minutes and texts. You’ll also get an allowance of mobile data, with the ability to roll over your unused data into the following month.

The following table shows SIM-only deals currently available from iD Mobile:

For £18/month, you can get unlimited data on iD Mobile. On this plan, there are no fair usage limits and no hidden restrictions on how much data you’re able to use.

You’ll need to undergo a credit check when taking a SIM-only deal from iD Mobile. For this reason, you may sometimes be better off choosing an alternative mobile network like giffgaff, SMARTY or VOXI where no credit check is required.

If you’re looking for an alternative to iD Mobile, SMARTY is probably the closest alternative. Like iD Mobile, SMARTY offers 3G & 4G coverage from the Three network, with competitive plans from £6/month and no need for a credit check:

Pay Monthly Phones

If you’d like to buy a new smartphone, you can get one on a 24-month contract from iD Mobile. These contracts are sold on the iD Mobile website as well as through the Carphone Warehouse, e2save and Mobiles.co.uk.

At present, a range of handsets are available from manufacturers including Apple, Samsung, Alcatel, Google, Honor, Huawei, Motorola, Nokia, Oppo and Sony.

It’s normally worth comparing contract costs across the multiple websites selling iD Mobile contracts as you may get a better value deal on one of the smaller websites. For instance, both e2save and Mobiles.co.uk are also owned by the Carphone Warehouse, but often have lower prices as they don’t have physical stores on the high street.

A full list of available handsets can be found on the iD Mobile website. You can also compare the price and selection against handsets from the Carphone Warehouse, e2save and Mobiles.co.uk websites.

Pay As You Go SIM

For customers who don’t want the hassle of undergoing a credit check, iD Mobile also offers a Pay As You Go service.

On Pay As You Go, you can choose from three Pay As You Go bundles, costing between £5 and £15 per month:

NetworkMinutesTextsDataMonthly
Cost
iD Mobile150Unlimited500MB£5.00
iD Mobile500Unlimited4GB£10.00
iD Mobile1,000Unlimited8GB£15.00

Outside of your inclusive bundle allowances, you’ll pay 3p/minute, 2p/text and 1p/MB on a traditional Pay As You Go basis. You’ll need to use your SIM card for a chargeable activity at least once every 90 days in order to keep it active. Your top-ups will also expire 365 days after the date of the relevant top-up.

Because of iD Mobile’s uncompetitive bundles, we’d recommend against choosing them on a Pay As You Go basis. Other mobile networks will give you much more data for the same monthly price and with no need to undergo a credit check. SMARTY is perhaps the closest alternative to iD Mobile, with them also offering bundles with coverage from the Three network:

Features

Data Rollover

One of the key features of iD Mobile’s SIM-only deals and Pay Monthly plans is the inclusion of a data rollover feature. It gives you a second chance to use the data on your plan.

For instance, if you have 1.2GB of unused data remaining on a 4GB plan, the 1.2GB will be rolled over into the following month. This will give you 5.2GB of data to use the following month (the original 4GB plus 1.2GB of rolled-over data). Your rolled-over data will always be used first, and data can only be rolled-over for a maximum of one month.

Unfortunately, data rollover is not available on iD Mobile Pay As You Go.

Bill Capping

Like all other UK mobile networks, iD Mobile offers a spend cap as a feature of their service. This allows you to set a limit on additional charges on your plan, with a cap between £0 and £25 per month. It can prevent unexpected or accidental charges on your bill.

To give an example, if you have a £10 plan with a £5 spend cap, your total monthly spend will be limited at £15 per month. If you reach the £5 limit on out-of-plan usage, you’ll be notified about this and further out-of-plan usage will be blocked on your SIM card.

Roaming in 50 Destinations

On iD Mobile, you can use your mobile phone abroad at no extra cost in 46 EU & EEA destinations, plus four Eurasian destinations (Azerbaijan, Belarus, Macedonia and Kazakhstan). The addition of four Eurasian destinations is fairly unique to iD Mobile but we suspect few people will be planning to travel to those places.

For more information about iD Mobile’s inclusive roaming feature, please see the iD Mobile website.

Unlimited Data

You can get an unlimited data SIM card on iD Mobile for £18 per month. This gives you 3G and 4G coverage from Three, with no hidden fair usage limits on your usage of the service.

£20 per month plans

For £18 per month, you can currently get a SIM card from iD Mobile with unlimited minutes, unlimited texts and unlimited data.

It’s also possible to get an unlimited data plan on many mobile networks, with unlimited data on Three available from just £18/month. For many people, we think this is a better value option as you’ll get access to 5G at no extra cost and access to the Go Roam offer with inclusive roaming in 71 destinations.

Network & Coverage

3G & 4G Coverage from Three

iD Mobile is a budget mobile network from the Carphone Warehouse, using coverage from the Three network. Customers on iD Mobile have access to Three’s 3G and 4G network, but not to Three’s 5G network which has recently launched in major towns and cities.

At the time of writing, this means iD Mobile offers 99% population coverage, with a signal available in the same places you can get a signal from Three.

Before ordering your iD Mobile SIM card or phone, we’d strongly recommend double checking the coverage in your area. You can do this by entering your postcode on the iD Mobile website:

Check iD Mobile coverage (idmobile.co.uk) →

On some devices, it’s also possible to use Wi-Fi Calling and 4G Calling capabilities on iD Mobile. For more information, see the iD Mobile webpages about their Wi-Fi Calling and 4G Calling features.

Like Three and like all other mobile networks using coverage from Three, iD Mobile doesn’t provide any 2G coverage. For this reason, you can’t use a 2G-only handset on iD Mobile. Your mobile phone will also be unable to fall back to 2G coverage. Some dual-SIM phones may not work correctly on iD Mobile due to a lack of 2G.

5G Coverage

Unfortunately, iD Mobile doesn’t currently offer any 5G coverage. They’re also yet to make an announcement on 5G will become available, so we think it’s unlikely we’ll see 5G any time soon on iD Mobile.

If you’d like to benefit from 5G coverage on the Three network, consider getting a SIM-only deal from Three instead. Three offers 5G-ready SIM cards from only £5/month, with access to Go Roam Around The World in 71 destinations.

At present, Three offers 5G coverage in the following UK towns and cities:

Now Live68 towns and cities are live on Three 5G (September 2020)
Aberdeen, Abingdon-on-Thames, Aldershot, Aldridge, Balloch, Barrow-in-Furness, Basildon, Bath, Bedford, Birkenhead, Birmingham, Blackpool, Borehamwood, Bradford, Brighton, Brookmans Park, Cannock, Cardiff, Chatham, Clayton-le-Woods, Coventry, Crawley, Cullingworth, Derby, Doncaster, Dundee, Glasgow, Gorebridge, Grays, Grimsby, Guildford, Heanor, Hedge End, Hemel Hempstead, Huddersfield, Inchinnan, Ipswich, Leeds, Leicester, Leyland, Liverpool, London, Lower Stondon, Luton, Maidstone, Manchester, Mansfield, Motherwell, Neston, Newquay, Nottingham, Nuneaton, Peterborough, Plymouth, Preston, Reading, Redcar, Royston, Sheffield, Slough, St Albans, Stevenage, Swadlincote, Swindon, Telford, Westhoughton, Wickford, Wigan

For more information, see our guide to the 5G rollout in the UK.

Tethering & Personal Hotspot

Tethering or personal hotspot refers to the process of sharing your smartphone’s internet connection with other devices (e.g. with your laptop or tablet). It’s a good way of getting a mobile broadband connection on your other devices.

Until the end of 2018, tethering wasn’t permitted for customers on iD Mobile. This was restricted in their terms and conditions. In 2019, the restriction on tethering was removed. iD Mobile also posted the following information on their website:

Can I tether on iD Mobile?
You can tether on iD Mobile, but please be warned – it can use up a lot of data very quickly and can work out to be very costly if you don’t take the right precautions (see the below FAQ for more details).

How much does tethering cost?
It takes a lot more data to do things on a laptop than on a phone, even if you’re just playing games or streaming videos. So, if you’re using your network connection to tether, you’ll use up more data than you might think.

While the wording suggest that tethering is not encouraged by iD Mobile, there shouldn’t be any restrictions stopping you from using it on their service.

International Coverage

iD Mobile offers an international roaming service so customers can use their smartphone when travelling abroad to other countries.

When travelling to other EU & EEA destinations, it’s possible to use your UK allowances at no extra charge (subject to iD Mobile’s open data fair usage policy). In addition, you can use your normal UK allowances when travelling in Azerbaijan, Belarus, Kazakhstan and Macedonia.

In other countries, it’s likely to cost substantially more using your iD Mobile SIM card. You can see detailed information on international roaming charges on the iD Mobile website.

Keeping Your Phone Number

If you’re changing from another mobile network to iD Mobile, it’s a straightforward process keeping your current phone number.

Start off by getting a PAC Code from your old mobile network. You can get one through your mobile network’s website or app, or by texting PAC to 65075. It’s free to obtain a PAC Code and you should be sent one within 60 seconds of your request.

Once you have the PAC Code from your old network, you can order your new SIM card or phone from the iD Mobile website. Alternatively, you can order your plan from the Carphone Warehouse, e2save or Mobiles.co.uk websites.

When your new phone or SIM card arrives from iD Mobile, you’ll initially be given a temporary phone number. You can use this to try out the service. Once you’re happy to move your phone number over, you can submit your PAC Code through the iD Mobile website. Your phone number transfer will then normally take place on the next working day.

For step-by-step instructions on how to move your phone number to iD Mobile, please select your current mobile network from the drop-down menu below:

  • Been charged for incoming texts off family and friends whilst in Turkey at 60p a text and Id are saying this is correct, so been charged overall £16.20 for friends and family to text me, ludicrous and cannot find anywhere that whilst outside the eu incoming texts from family and friends are chargeable.
    Now at ombudsmen stage and looking forward to ditching my contract after this fiasco.
    Check your bills when you have been outside the EU.

    • Hi Sonia,
      Sorry to hear about the unexpected charges you’ve encountered on iD Mobile. I’m only aware of a fee for outgoing text messages – I don’t believe there should be a fee for receiving a text (as you don’t have the option of whether to accept the message). Is the fee definitely for receiving a SMS message, rather than something else (e.g. voicemail or roaming data)?
      Ken

  • Hi
    Honestly speaking I wouldn’t recommend ID mobile to any of my friends or family because of what they did with my credit rating.i quit ID in a matter of few months as I was not happy from day 1 of receiving the pay as you go sim. The customer service is bad and if u do not set a direct debit you had it. The worse nightmare I had was recently when I applied for a credit report and noticed it to be bad the reason being because of ID mobile , when went into the matter found out that I was in credit with them £3.50. When asked why my credit report shows me to be at default they said it will be cleared after 30 days.When checked again on the 1st October 2017 it’s still the same. Imagine how anyone would feel if that’s done to them.No matter how many times u call them it’s like talking to a deaf person.Ive lived in the Uk for 11 years & never had such an experience or such a bad credit rating. Please don’t be fooled with their low cost or whatever they offer you stay away from getting trapped by them
