iD Mobile SIM-only deals explained

iD logi and SIM card

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 data capping.

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 500MB of data with 500 minutes and 5000 texts, up to 6GB of data with 2000 minutes and 5000 texts.

All of iD Mobile’s SIM-only plans are available on one-month contracts, and include data capping, data rollover and inclusive EU roaming.

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

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 throughout the EE, EEA and beyond. All minutes, data and texts simply come out of your remaining monthly allowances

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 and how many minutes and texts do you need per month?
  • Contract length - all iD Mobile’s SIM-only deals are one-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?

No, we're afraid unlimited data isn't available with iD Mobile. The maximum monthly data allowance you can get is 6GB, on a one-month contract. If your phone use includes lots of apps, watching some videos and browsing the web, then this should be plenty.

If you’re a heavier user and don’t think 6GB is enough data, then you may need to check out unlimited and big data options from other networks instead.

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

The cheapest mobile SIM deal you can get from iD Mobile is a one-month plan that comes with 500MB data, 500 minutes and 5000 texts per month.

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. However, if you stream TV shows and watch a lot of video, you should look at plans with larger data allowances.

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 12-month 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 size SIM card do I need?

There are three SIM card sizes you can get:

  • Standard SIM card - 15mm x 25mm, commonly used in older feature phones
  • Micro SIM card - 12mm x 15mm, used in some smartphones, primarily older models
  • Nano SIM card - 8.8m x 12.3mm, used in most modern phones, including popular handsets like the iPhone 8 and Samsung Galaxy S8

Don't worry if you have no idea which size your phone takes. Most networks will send you a 3-in-1 SIM, designed to fit into any handset. It'll come encased in plastic, and you can pop it out into the size you want.

In other words, don't stress about SIM size when comparing deals. Whichever you choose, the SIM card will fit in your phone.

Does my phone have to be unlocked to use an iD Mobile SIM?

Some phones are locked onto a particular network, and will need to be unlocked before you can use another company's SIM. Fortunately, this is really easy to do. To find out if your phone is locked, pop in a friend's SIM card - they'll need to be on another network obviously. If it works, then your phone is good to go - otherwise, you'll need to contact your current operator and ask them to unlock it.

Different networks have different rules on unlocking. Some examples are:

  • Three - all handsets are unlocked out of the box.
  • O2 - phones are locked, but O2 will unlock them for free when you're out of contract. Pay-as-you-go (PAYG) customers will have to pay though.
  • Vodafone - phones are locked, but Vodafone will unlock for free.
  • EE - phones are locked, but EE will unlock for free - so long as you're out of contract. PAYG customers must wait 12 months after purchasing to unlock.

Those are just the major networks. To find out more about unlocking your mobile, check our full guide:
