DePinSim is a decentralized connectivity infrastructure network empowering borderless communication and payments via crypto-native (e)SIMs. It aims to reshape crypto entity (by introducing a mobile number based DID with built-in wallets), redefine Web3 user acquisition (with a task-to-earn system that rewards users with free data and other airdrops), and revolutionize DApp connectivity (by offering a global roaming eSIM built on Telegram and a data marketplace).
