iD Mobile review 2021

By Dan Howdle | Monday, April 26th 2021

iD Mobile

iD Mobile was launched by Dixons Carphone in 2014 with a promise to solve common frustrations with other mobile operators by offering cheap, flexible 4G services on the Three network.

It has since developed a reputation for value and flexibility, offering a range of pay monthly, SIM-only and pay-as-you-go tariffs. Powered by the resources and reach of its parent company, iD is now one of the most influential mobile virtual network operators (MVNOs) in the UK, offering a genuine alternative to the big four operators. But is iD Mobile right for you?

Tariffs and plans

iD Mobile offers a range of pay monthly phone deals and well-priced SIM-only plans. Data allowances start from 2GB and go up to deals with unlimited data. All deals come with unlimited texts and minutes.

Most pay monthly deals with a handset will tie you down to a 24-month contract, but the SIM-only deals are available both on one-month or 12-month contracts, offering flexibility to those that want it. The 12-month plans offer better value than the one-month plans however, with more data for the same or less money.

All iD plans come with data rollover, which means that if you have any unused allowance at the end of the month, you can use it in the following month. This data is used up first and you have the entire month to consume it all. Additionally, you can also set a cap on your monthly spend, so there’s no prospect of bill shock if you go above your allowance.

Phone and device range

If you want a new phone, then iD has a wide range of handsets on offer, including devices from the major manufacturers. Customers looking for the latest handsets from Apple or Samsung will be pleased to find the Apple iPhone 12 Pro and Samsung S21 available. There are also older Apple and Samsung models on offer, along with devices from Google, Huawei, Sony, Nokia, Honor, Motorola and Oppo. Budget options from Doro and Alcatel mean that every taste and budget is catered for.

All handsets come with a choice of two upfront costs so you can choose to pay off more of your handset upfront if you wish, or pay more every month. Older handsets come with lower upfront costs and some without an upfront cost at all.

iD does not offer customers the opportunity to buy a new handset outright; they are only available on a 24-month repayment contract. There is also no option to pay off your handset early and upgrade to a new one, so you are committed to iD for 24 months if you take out a new pay monthly phone deal.

Customer service

iD Mobile has a live online chat service running between 9am and 8pm during the week and between 9am and 6pm on weekends and bank holidays. Unlike most mobile providers, there is no customer phone line to call, although iD does have an active online community of over 40,000 members where you can ask questions and resolve issues. There is also a database of frequently asked questions on the provider’s website which may provide you with a solution.

iD Mobile is not covered by regulator Ofcom’s regular complaints bulletins, although in Ofcom’s most recent survey into customer satisfaction, host network Three had an above-average number of customers with a reason to complain and also ranked lowest when it came to customer satisfaction with the service overall, with 89% compared to 97% with Tesco Mobile.

Online reviews should always be taken with a healthy dose of scepticism because people tend to report negative experiences more frequently than positive, but iD Mobile currently has a rating of 3.8 out of 5 on TrustPilot, which compares favourably against Three with 1.8 and EE with 2. The main complaints about iD tend to be with customer service issues.

Value for money

In terms of base cost, iD Mobile is excellent value for money as it has some of the cheapest SIM-only plans in the UK. Its handset deals may not offer the same level of freedom because of the 24-month minimum term, but the monthly cost compares favourably with the competition.

But iD Mobile’s ‘no-frills’ attitude does mean its plans are comparatively spartan. There’s no loyalty app, streaming offers or free content to sweeten the deal, so when you’re comparing an iD tariff to one from another network it’s important to remember what you might be giving up.

Inclusive roaming is available with iD in 50 countries: across the EU and a few bonus countries beyond, including Martinique, Kazakhstan and Belarus.

Network coverage

iD Mobile uses Three’s mobile infrastructure to power its network, so you’ll benefit from all the investment made in recent years. Three’s 3G and 4G networks cover 99% of the UK population and the operator has been rolling out extra spectrum over the past few years to spread coverage, especially indoors.

Three is also now rolling out its 5G network, which it claims will be the fastest in the UK, but coverage is currently very limited. However, iD does offer 5G-ready SIM-deals and handsets so if you are in a 5G area, you can take advantage.

The iD network covers most of the country

Three was the last UK operator to launch 4G, but it has made significant strides in the past few years as demonstrated by its performance in independent tests.

According to the most recent tests from benchmark firm RootMetrics Three ranks third in the UK behind EE and Vodafone for overall performance and third in the reliability, data and speed categories.

iD Mobile does offer 4G calling if you have a compatible handset. 4G Calling offers superior call quality, uses less battery life and can make it easier to make and receive calls indoors because 4G networks use low-level, high-range spectrum that can penetrate buildings and walls far more easily.

Check iD Mobile coverage


If you’re looking for a cheap contract, then there are few better places to go than iD Mobile. Its SIM-only deals offer good value, but to get the most for your money you’ll need to commit to a 12-month contract. The one-month deals offer flexibility however, and there is also plenty of choice when it comes to both handsets. Just bear in mind that Three doesn’t fare as well when it comes to coverage and signal compared to the other networks.
