We think iD Mobile's best value option on SIM only this December is their £10 a month plan below, which comes with 50GB data, plus unlimited minutes and texts on a 1‑month deal:

If you're open to joining other networks than iD, you can actually get a similar deal for less, even with providers whose SIMs also use the Three network. See the networks that beat it here:

We also like their £7 for 12GB plan

For people who don't need that much data, you might like the £7 SIM only deal running on iD Mobile at the moment. It's a 1‑month plan, which comes with 12GB data, unlimited minutes and texts too:

While it's good enough to be in our pick of iD's best SIM only deals, other providers do still have similar plans for less, even ones that also use the Three network. Here are the networks where it'd cost less:

Their 4GB for £6 SIM is another good option

In our iD Mobile review, we said they were a low-cost provider with full access to Three’s 5G network and the same coverage and speeds as being on Three directly. We also liked that they offer WiFi calling and 4G calling.

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 Mobile have competitive prices on their whole range of SIM only plans. They can often be the cheapest way onto Three’s network (alongside SMARTY) depending on what offers are available.

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.

iD Mobile will send you a physical SIM within 2-3 working days. The package that arrives will have each size of SIM card to fit any phone. They don’t offer eSIMs (see the networks that do).

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.

No matter if you take a 1-month, 12-month or 24-month SIM only plan, you’ll have to pass a credit check to get on iD. If you’ve failed a credit check with them you can take a payg bundle which you pay for up front.

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.
