We think the best value for money SIM only plan on iD Mobile for June is their 200GB for £14 deal. It's on a 1‑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 200GB data or more. See under the dropdown to see how the competition it undercuts:

There's not currently a better SIM only deal on the market than iD's one above if you want 20GB data or more. Here's the closest their competitors get for similar plans:

There's also a nice 30GB for £8 plan with them this month

If you need more data, iD Mobile are also offering this £8 SIM, which includes 30GB data, unlimited minutes and texts on a 1‑month plan. It's another of their best deals:

It might not be the lowest-cost SIM only deal with 30GB 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 other networks you can beat it on:

Or their £16 for unlimited data SIM plan is worth a look too

For even more monthly data, you might like the £16 SIM only deal running on iD Mobile at the moment. It's a 12‑month plan, which comes with unlimited data, unlimited minutes and texts too:

It does enough to get into our pick of iD's best SIMs but that doesn't mean it's unbeatable on price. Other providers (even ones that use the Three network) can beat it. See the networks with cheaper plans here:

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.
