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?

Sold out in your size? RestockAlert watches the product page so you don't have to. Paste a link from a supported store, pick the exact sizes you care about, and we'll keep checking that page in the background. The moment your size comes back, you get an alert with a direct link to the product. No browser extensions, no refreshing, no luck required. HOW IT WORKS 1. Drop in a link. Copy any product URL from a supported retailer and paste it into the app. We pull in the product name, price and available sizes automatically. 2. Pick your sizes. Track one size or several. Everything else is ignored, so you only hear from us about the thing you'd actually buy. 3. Get the alert. When a tracked size flips back in stock, the notification lands with a tap-through link straight to the product page. WHERE YOUR ALERTS ARRIVE - Email, included on every account - Telegram, instant messages from our bot, on paid plans - Push notifications, native alerts on your iPhone, on the Pro plan Every channel has its own switch in your profile, so you can turn off the ones you don't want. SUPPORTED STORES Zara, H&M, Mango, COS, Bershka, Sephora, Coach, Coach Outlet, Net-A-Porter, PrettyLittleThing, American Eagle, Walmart, Target, DFYNE, YoungLA and Dua Fragrances, with more added regularly. New stores show up in the app on their own. You never need to update to get them. ALSO IN THE APP - A live dashboard of everything you're tracking, with the current price and per-size availability - Search across your trackers - Add, pause and remove trackers in a tap - Sign in with Apple, Google or email - Your trackers stay in sync between the app and the web dashboard - Delete your account from inside the app, with a grace period in case you change your mind GOOD TO KNOW Free accounts track up to 3 products at a time and get email alerts. Higher tracking limits, more frequent checks, Telegram and push alerts come with the paid plans. Each tracker keeps running until your size is back or the tracking window on your plan runs out. We only read publicly available product pages. We never buy, reserve or check out anything on your behalf. When your size is back, the purchase is yours to make. Missing a store you shop at? Tell us and we'll look at adding it.
