iD Mobile's best SIM only deals
Our highest-rated SIM only deal on iD Mobile this month
Out of all the SIM only plans available this March on iD Mobile, we'd say their best value deal is their 1‑month SIM below, which gets you 10GB data, plus unlimited minutes and texts for £7 a month:
In comparison to the rest of iD's current SIM only plans, it's one of the best. But it is beatable on price, even if you're set on joining a provider that uses the Three network. Here are the networks offering it cheaper:
They've also got a 100GB for £12 SIM plan at the moment
To get more data, another option for you on iD, is their 12‑month SIM below, which costs £12 a month for 100GB data and comes with unlimited minutes and texts:
You can't actually currently beat iD's prices there for a SIM only deal with 100GB data or more on any other provider. Here are the closest alternatives each network is currently offering:
iD's £10 for 60GB is our next best choice now
If you don't want so much data, iD have got a £10 deal on SIM only we think's worth looking at. It gets you 60GB data, unlimited minutes and texts and it's a 12‑month plan:

How iD Mobile's SIM only prices and benefits compare
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.
