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:

  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.
