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 โ€” or completely wipe out โ€” 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 โ€” 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 ยฃ0.00. 220+ BRANDS AND COUNTING Groceries, coffee, fashion, gaming, travel, electronics, beauty, toys and more โ€” 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 โ€” 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 LIVE IN 60 SECONDS Choose an eSIM on Mozillion's website and you're connected in about a minute โ€” scan the QR code, add the plan in your settings, done. Prefer plastic? We'll post you a physical SIM instead. IN THE APP YOU CAN - Browse 220+ brands and buy eGift cards in seconds - See exactly what reward a purchase earns before you buy it - Track your running total and watch your next bill shrink - Send gift cards to friends and family โ€” and earn rewards on those too ALREADY WITH MOZILLION?
