What Is Mozillion Kill Your Bill?

The feature that makes this deal stand out is Mozillion Kill Your Bill.

The concept is simple. Through the Mozillion app, you can purchase eGift cards from participating retailers. Every time you shop, you receive an instant reward that is applied directly to your Mozillion phone bill.

According to Mozillion, some customers paid £0 last month by using the scheme regularly.

How Does Kill Your Bill Work?

  2. Choose a participating retailer.
  3. Purchase an eGift card.
  4. Use the QR code in-store or enter the code online.

The rewards accumulate over time and can reduce or even completely eliminate your monthly payment.

Even better, if your rewards exceed your monthly bill, the remaining credit rolls over to future bills.
