Looking at all iD Mobile's options on SIM only this February, the deal that jumps out to us is their 150GB for £12 one below. It's a 24‑month plan and comes with unlimited minutes and texts too:

It's certainly a good deal from iD. No other network can beat them for price on a SIM only plan with 150GB data or more. See under the dropdown to see how the competition it undercuts:

For those with smaller data needs, we'd say this is one of iD's best deals on SIM only this month too. It's a 1‑month plan, comes with 50GB data, unlimited minutes and texts for £8 a month:

It's actually possible to beat this deal if you're not fussed whether your SIM is with a provider using the Three network. But if you are, it is the current best-priced option. See where you can get it for less here:

Their 25GB for £7 SIM is another good option

If that's more data than you need, have a look at iD Mobile's 25GB SIM below at £7 a month, as it's another good deal. It's on a 1‑month plan and comes with 25GB data, unlimited minutes and texts:

It might not be the lowest-cost SIM only deal with 25GB data or more on the entire market but if you're sure you need a SIM using the Three network, it is the best-priced. Here are the networks offering it cheaper:

In our review of iD Mobile, we said we liked that they offered full access to Three’s network (including identical 5G speeds and coverage) on low-cost deals. And they have an excellent WiFi calling scheme as well.

You can choose either a 1-month, 12-month or 24-month contract on iD. It tends to be the case that longer contracts cost you less per month. But it’s still worth checking to see what their best current deals are.

iD tend to offer great value on all their SIM only plans, and the cost of your plan won’t increase during your contract so you can hold onto that value. They’re usually one of the cheapest ways onto Three’s network.

They’re fairly low-frills, but they do have a good data rollover scheme that lets you keep unused data for your next month. They also offer inclusive EU roaming. But they don’t offer much else.

Your iD Mobile SIM card will be delivered within 2-3 working days after ordering. You’ll get each size of SIM card in your package to fit any phone. iD don’t offer eSIMs yet (see the providers that do here).

When you order anything online you have 14 days to get a full refund, and this is also the case for SIM cards. Here’s how you can get a refund if you’re unhappy with your SIM.

You’ll have to pass a credit check to join iD, no matter if you want to join on a 1-month, 12-month or 24-month contract. If you’ve been rejected for a contract you can still join on a PAYG monthly bundle.

If you’re switching from one network to get onto iD Mobile then you can keep your number by requesting a PAC from your current provider to give to iD. Here’s more info on how to do that.
