Mozillion

PLEASE NOTE: This is not an app to manage your Mozillion account. It is a shopping app to manage your Kill Your Bill Giftcard purchases.

Shop like normal. Kill your phone bill.

You're already spending at Sainsbury's, Costa, ASOS and 200 other brands. Mozillion turns that everyday spending into cash rewards that shrink — or completely wipe out — your monthly phone bill.

No extra spending. No points to chase. No other UK network does this.

HOW KILL YOUR BILL WORKS

1. Pick a Mozillion SIM only plan with Kill Your Bill included from the Mozillion website
2. Open the app before you shop and buy an eGift card for wherever you're heading. Takes about 10 seconds.
3. Pay with it as normal — same shop, same basket, same total.
4. Your reward lands straight on your phone bill.

Do that a few times a month and your bill can reach £0.00.

220+ BRANDS AND COUNTING

Groceries, coffee, fashion, gaming, travel, electronics, beauty, toys and more — including Sainsbury's, ALDI, Costa, Greggs, Boots, Argos, John Lewis, Nike, adidas, H&M, Gymshark, Starbucks, Uber, Airbnb, Hotels.com and Nintendo. New brands added every month.

REWARDS THAT ROLL OVER

Earn more than your bill is worth? The extra credit carries over to next month. It never expires — so a busy shopping month keeps paying you back in a quiet one.

Every Kill Your Bill plan includes:
- Kill Your Bill rewards
- Unlimited calls and texts
- Uncapped 5G speeds
- Free EU roaming
- Rewards that roll over and never expire
- No mid-contract price rises
- No booking fees or hidden charges
