BAYCON Inc. is a Seoul, South Korea-based mobile connectivity company, founded in 2018 and backed by 500 Global and Shorooq Partners (seed round, 2024). BAYCON operates a global data eSIM platform and a family of international communication apps: eSIM Easy (이심이지), which delivers multi-country data eSIM plans as a QR code within minutes of purchase; ModuCall (모두의 국제전화), affordable VoIP international calling that lets users place overseas calls using their domestic mobile plans; and BayTalk. The company partners with local network operators and global carrier infrastructure so international travelers and businesses can access local mobile networks without physical SIM cards, cut roaming costs, and stay connected across borders, and is expanding into travel content such as attraction tickets and transportation passes. BAYCON publishes consumer mobile apps rather than a public developer API surface.
