We look at how each of iD Mobile's best SIM only deals compare on price against their competitors this month. These are our findings. SIM Sherpa is your trusty guide. Last updated: 1st December 2023.

iD Mobile's best SIM only deals

We think iD Mobile's best value option on SIM only this December is their £9 a month plan below, which comes with 63GB data, plus unlimited minutes and texts on a 1‑month deal:

This isn't the very cheapest deal with 63GB data or more out now. But if you definitely need a SIM only plan that uses the Three network, we think it is the best option. See the networks that beat it here:

We also like their £8 for 50GB plan

For people who don't need that much data, you might like the £8 SIM only deal running on iD Mobile at the moment. It's a 1‑month plan, which comes with 50GB data, unlimited minutes and texts too:

You can get a lower-priced SIM with 50GB data or more elsewhere if you don't need it to use the Three network. But if you do need that, it is the cheapest deal available. Here are the networks where it'd cost less:

Their 30GB for £7 SIM is another good option

If that'd be too much data for you, 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 30GB data, unlimited minutes and texts for £7 a month:

This is actually the leading price in the UK at the moment for a SIM only deal with 30GB data or more. The plans under the dropdown are the next nearest you can get to iD with other providers:

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.
