iD Mobile SIM-only deals explained

iD logo

iD Mobile plans offer excellent value for money on some reasonably-priced SIM-only tariffs. Their 30-day rolling plans don’t tie you down, so you are able to change up or down each month.

Compare deals

You also get some useful benefits such as data rollover and inclusive roaming.

Here's what's available from iD Mobile’s SIM-only roster, and how you can find the best deal for you.

What SIM-only deals can I get from iD Mobile?

Monthly allowances range from 4GB up to unlimited data, all with unlimited calls and texts too.

You can pick your contract length from one-month, 12-month, or 24-month plans. With some allowances, the longer you're willing to commit, the lower your monthly bills.

Perks and benefits

All pay-monthly SIMs from iD Mobile get you these benefits:

  • Roll your unused data over to the next month, every month
  • Up to 5 months' free Apple Music, Arcade, and News+ apps
  • Wi-Fi calling
  • Cap your data and put a limit on your monthly spend, so you won’t pay more than you can afford
  • Inclusive EU roaming allows you to roam at home in 50 destinations - all minutes, data and texts simply come out of your remaining monthly allowances

Is iD Mobile a good network?

iD Mobile is one of the more affordable providers in the mobile world. That’s not to say it does things on the cheap, though.

It uses Three’s wide-ranging 4G and 5G networks, as well as offering solid benefits such as data rollover and EU roaming.

Seeing as the latter is no longer a guarantee from major networks including EE and Three, it’s a handy addition.

Prices are competitive and coverage is excellent, while its data allowances range all the way up to unlimited. If you want the basics done well, iD is a good place to start.

How to compare iD Mobile SIM-only deals

Comparing iD Mobile SIM deals is easy - just use the table at the top of this page. You can see all the deals together, compare what you can get, and filter them down so you only see the ones that suit what you need.

Think about things like:

  • Allowance - how much data do you need per month?
  • Contract length - iD Mobile’s SIM-only deals are either one-month, 12-month, or 24-month contracts
  • Price - if you have a budget, choose the maximum you want to pay each month in the cost filter

Click on the deal you like best, and we'll take you to iD Mobile's website so you can sign up and get started.

If you're not convinced iD Mobile is the network you want, that's no problem - you can compare its deals right next to those from other providers too.

Just select the networks whose SIMs you'd like to see and we'll show you the lot. Or, compare all SIM deals here.

Can I get an unlimited data iD Mobile SIM?

Yes you can. Unlimited data SIM-only deals from iD Mobile come with unlimited calls and texts too, and are available on a one, 12, or 24 month basis.

Remember you’ll pay less per month if you choose a longer contract, although of course you’ll lose the flexibility of switching whenever you like if you do so.

What's the cheapest iD Mobile SIM-only deal?

The cheapest SIM-only deal you can get from iD Mobile gives you 1GB of 5G data and unlimited calls and texts for just £5 per month.

However, paying a quid more a month will score you 5GB of 5G. Both deals are one month rolling plans.

Some of iD Mobile’s cheapest plans offer good value for money if you’re a light to medium data user – and you mainly use your phone for apps and social media.

But if you stream TV shows and watch a lot of video, you should look at plans with larger data allowances. Handily, you can get unlimited and 100GB allowance deals to suit your needs.

To find the cheapest deal that fits your use, use our comparison table.

Adjust the filters to make sure you only see SIMs that have enough monthly allowance for you, and then sort the whole table by monthly cost. You'll see the lowest-priced deals right at the top.

You'll generally find that longer-term plans work out cheaper per month than 30-day ones, so it's worth the commitment if you really want to save money.

And sometimes there are limited time deals that are worth pouncing on - keep a beady eye out for those.

Is an iD Mobile SIM deal cheaper than a phone contract?

Yes, it's almost always cheaper in the long run to buy a phone outright and take out a SIM-only deal.

If you do want the benefits of a phone contract plan (like lower upfront costs, a nice new phone in your hand today, and free screen replacements), it’s worth seeing what other networks can offer.

Can I upgrade an iD Mobile SIM-only deal?

iD Mobile’s one-month rolling contracts don’t tie you down, and you can change your iD Mobile SIM-only plan up and down each month.

Can I keep my number if I switch to an iD Mobile SIM-only deal?

Yes - it's almost always possible to keep your current phone number when you switch to a new network.

1) Choose a new SIM-only plan - compare deals and sign up to one that you like the look of. Your SIM will be sent through the post to you. While you're waiting…

2) Contact your current provider and request your PAC (porting authorisation code) - you can request your code in a few ways - online, via text and even by post if you're really old-school. If you phone, they may try to talk you into sticking with them, but stick to your guns if this happens. They'll send you the PAC as a text message within two hours.

3) Give the PAC to your new network - when your new SIM arrives, it will have a new number. To change it to the old one, contact your network and give them the PAC code. They'll take care of porting the number over. It could be as fast as one working day before the old number's transferred, but be aware that on occasion it can take a little more time.

It may sound complicated, but it's very simple in practice. If you want a bit more detail, check out our full guide to keeping your phone number:

What network is iD Mobile using?

iD Mobile uses Three’s network. Three’s 3G and 4G networks cover 99% of the UK, while its 5G has been independently verified as the fastest in the UK, with lightning fast speeds of over 400Mbps.

That’s better than most home broadband connections.

Going with iD Mobile may mean you miss out on Three’s perks, but its deals are more flexible and you get roaming as standard, something Three no longer offers.

Roaming with iD Mobile

Unlike Three and EE, iD Mobile offers inclusive roaming on all its SIM-only plans at no extra charge.

This means you can use your calls, texts and data in over 50 destinations around Europe without paying extra. A fair usage policy applies, however.

This makes iD Mobile a serious proposition for anyone who travels a lot and needs to be able to use their phone without the fear of bill shock when abroad.

What else can I get from iD Mobile?

iD Mobile doesn’t just offer SIM-only plans. It also has an excellent range of phone contract plans to choose from. This includes deals for the cutting edge Samsung Galaxy S22 and the top-of-the-range Apple iPhone 13 Pro Max.

Compare iD Mobile phone plans now and you can snag a great deal at an affordable price.

Frequently asked questions

Are iD Mobile SIMs 5G enabled?

Yes, you can get 5G enabled SIMs from iD Mobile. In fact, every iD Mobile SIM-only deal with Broadband Choices comes with 5G as standard.

That means you can future proof yourself and access the fastest networks on any 5G-enabled device. And whenever you’re in a non 5G area, you’ll get 4G or 3G instead.

Should I get unlimited calls and texts?

Every iD Mobile SIM-only deal comes with unlimited calls and texts as standard.

How do I cancel an iD Mobile SIM-only contract?

It’s easy to cancel or move your iD Mobile SIM-only contract. Use the MyID app and find End My Plan in the My Account section, text PAC and your date of birth in the DDMMYY format or request one online from my.idmobile.co.uk.

30 day plans can be changed at any time. Longer contracts will need to be within 30 days of ending before you cancel.

Can you get pay as you go iD Mobile SIMs?

Yes. iD Mobile pay as you go SIMs come with 4G as standard, include data roaming and don’t require credit checks. 1GB of data and unlimited calls and texts costs £6.
