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.

Why choose an iD Mobile SIM Only deal?

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 £0, 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.

What are the benefits of SIM Only?

If you already own a phone you're happy with, a SIM Only plan is a wise choice. Not only can you carry on using the device you love, you can look forward to paying less every single month too. As you'll no longer need to factor in the cost of a new handset, your monthly plan will simply include a bundle of minutes, texts and data that suit you.

SIM only contracts are popular thanks to their flexibility too. At iD Mobile, SIM Only deals operate as 30-day rolling contracts, meaning you can modify or end your contract easily by giving us a month's notice. It's great if you find your data usage fluctuates month to month, or if you're not ready to sign up to a new 12 or 24-month contract straight away. Got your eye on a new handset, which won't be released for three months? Try SIM Only while you wait!

On top of all of this, you'll still benefit from network perks like free EU Roaming as a SIM Only customer.
