What is a SIM only deal?

A SIM only deal works in the same way as a regular mobile contract - just without the handset. You'll pay monthly for minutes, texts and data, choosing a package that suits you best.

Considering switching to SIM only?

Speedy 4G is offered as standard with every iD Mobile SIM only deal too, and our multi-size SIM cards fit any smartphone to make life that little bit easier.

You'll be able to enjoy the same exclusive benefits all our other iD Mobile customers receive too. It doesn't matter if you choose a SIM only deal, have a regular monthly contract or Pay As You Go, every member of the iD family can look forward to free EU Roaming, Data Rollover and Capping.

With our Data Rollover feature, you'll get a second chance to make the most of your unused data. Whatever's left over from your monthly contract will automatically be carried over to the next month of your SIM only deal, meaning you'll never let a MB go to waste. Capping, meanwhile, ensures you'll never be surprised with a hefty bill. You have the ability to put a limit, from £5, on your out-of-plan spend too - we'll never let you use more than you've agreed.

Finally, EU Roaming lets all iD customers use their monthly data while abroad. Google directions, update Instagram or video call loved ones back home without worrying about the extra cost.

Legal stuff.

RPI Increase.

The charges you pay will adjust (up or down) in line with changes to the Retail Price Index Rate (RPI Rate) set by the Office of National Statistics. We will adjust charges with effect in your April bill after the RPI Rate is announced for the previous 12 months to February. We will publish the RPI Rate on our website as soon as it becomes available.

Fair usage policy.

Our fair usage policy applies to all pay monthly phone, SIM Only and Pay-as-you-go plans. Our open data policy applies to selected plans.

Your questions answered.

What is an iD pay monthly SIM only plan?

Our pay monthly SIM only plans work in almost the same way as our plans with phones. The only difference is that you don't get a phone as part of the deal. You simply get a new SIM card with a monthly allowance of minutes, texts and data.

What are the benefits of SIM only?

SIM only plans are perfect if you've already got a phone you're happy with. And they're great if you want to cut down on your mobile spend, because going SIM only usually works out cheaper than buying a plan with a phone.

If you've got your eye on a new phone that hasn't been released yet, going for a 30-day iD SIM only plan could make perfect sense. You can keep it rolling month-by-month, and end it as soon as your new smartphone becomes available.

What if I run out of minutes, texts or data?

If you run out of an allowance, you can still keep using it (for example, if you run out of texts you can keep sending text messages), but you'll be charged at out-of-bundle rates.

To prevent you from racking up these out-of-bundle charges, it's easy to purchase an add-on of minutes, texts or data (depending on which allowance you've run out of).

Please note: add-ons can't be backdated to cover your past usage. They come into effect when they're purchased, and never before.

Can I keep my number?

Yes. It's simple to keep your old mobile number when you sign up to an iD SIM only plan. We've created a simple step-by-step guide that you can view on our 'Keep your number' page.

What is the signal like in my area?

We'll always try to make sure you have the best possible coverage to keep you connected, wherever you are. Use our coverage checker to get an indication of what the signal is like in your area.

What size of SIM card do I need?

Your iD SIM card is 'one size fits all', so you don't have to worry about ordering the correct size. The card you receive contains all three SIM types (standard, micro and nano), and you just need to snap it into the size you need.

If you're not sure what size of SIM card your phone takes, you'll find this information in the device's user manual.
