FAQs.

Your UK add-ons (also known as domestic add-ons) starts once your monthly allowance is used up. For example, if you buy a UK data add-on, it'll kick in after your monthly data allowance and Data Rollover are used up. Make sure you buy the UK 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.

Our Roam Beyond & Call Abroad add-ons will start immediately once you complete the purchase.

At the moment, we only offer auto-renew Call Abroad add-ons. Auto-renew add-ons renew automatically every month at 00:00. Your renewal happens at midnight on the same date the next month.

If that date doesn’t exist in the next month, the renewal takes place at midnight on the final day of the month. For example, if you purchased an auto-renewing add-on on 31st March 2026 at 12:58, the add-on will expire on 30th April 2026 at 00:00. Every renewal gives you a fresh full month of minutes.

  • One off and auto-renewing add-ons can't be cancelled once they've been purchased.
  • One-off add-ons: They will remain active until they expire at the end of their stated duration.
  • Auto-renew add-ons: You can stop a monthly add-on from auto-renewing in the iD App via Plan > Add-Ons > Manage Your Add-Ons. Once disabled, it won’t renew and will expire either one calendar month from the date it auto-renewed or one calendar month from day of purchase if you are still within the first month. You can use the add-on until it expires or until the allowance runs out – whichever comes first.

No, add-ons are not included in your Bill Cap. If your Bill Cap is set at £3.00 and you buy a £3.00 add-on, you’ll still have £3.00 left on your Bill Cap. Find out more about how Bill Caps work here.

Yes, your add-on will remain on your account even if you change your plan.

If you go over your allowance, you’ll be charged out-of-plan charges until you buy an add-on. Remember, your add-on can’t be backdated or used to cover past usage. But once you’ve bought the add-on, it will help you with limiting out-of-bundle charges by providing better value.

If you’re travelling to one of our 50 Inclusive Roaming destinations, you can use your monthly allowances and UK add-ons at no extra cost, up to 30GB (subject to our fair usage policy). We now also offer Roam Beyond data add-ons in select destinations.

Please note: you cannot use your Call Abroad add-ons whilst being overseas.
