To receive your unique basket code, simply sign in to your UNiDAYS, GRADLiFE or TOTUM app. This discount isn’t available on in-store purchases so make sure you order online!

Why is my O2 discount code not working?

There can be many reasons why a discount code for O2 doesn’t work. The most common reasons are:

  1. It may not be valid for the specific phone or sim card you have in your shopping basket.
  2. The code may only be valid for new customers.
  3. The phone / sim card may already be discounted or on sale.
  4. The code may have been expired early due to limited availability.

It’s best to thoroughly read the individual terms and conditions for each code to avoid disappointment.
