Add-ons are a great way to top up your data and minutes. Let’s take a look at the types of Add-Ons available and see how they work:

You should have enough allowances for each month, but things can change! There might be an unmissable new Netflix series you can’t stop binge-watching on your daily commute – this can eat up a lot of data. Or, if you’re on the phone for several hours a day, you could run out of minutes. 

If you think you’ll run out of minutes or data before your monthly allowances refresh, we recommend you top up with an add-on. Buying an Add-On works out cheaper than racking up those dreaded out-of-plan charges. For example, a 7-day Add-On of 100MB data is just £1.00. But if you use an extra 100MB of data outside your plan without an add-on, you’ll be charged £10.24.

Your Add-On kicks in once your monthly allowance is used up. If you buy a data add-on, it starts being used after your monthly data allowance and Data Rollover are used up. A calls Add-On starts once your monthly minutes allowance is used up. You can buy Add-Ons that last for 7 days, 1 month or 12 months. Make sure you buy the Add-On when your allowance is close to running out. A 7-day data Add-On will expire exactly seven days after you bought it, not seven days after it starts being used.

Add-Ons can be viewed and purchased any time in the iD Mobile app or My Account online.

These are no longer available to buy from us. However, if you have an existing recurring add-on, it'll keep refreshing every month when your new billing period starts. It'll stop recurring when it expires, or if you cancel it.
