A recharge app is a mobile application that allows users to easily recharge their mobile phones, DTH (direct-to-home) services, or other utility bills like electricity, gas, and water bills. Users can top-up their prepaid mobile plans or pay their postpaid bills through the app, and the payment can be made via various payment options like debit/credit cards, net banking, UPI, or e-wallets. The app usually provides users with various recharge plans and offers, making it a convenient and cost-effective way to stay connected and pay bills.
