I just launched a travel eSIM store: HaiHui. International roaming is ridiculously expensive, so I built a simpler solution. Travelers can buy instant eSIM data in 190+ countries. No physical SIM cards. No airport kiosks. No contracts. Buy → install → connect in seconds. Now I’m also launching the HaiHui mobile app for iOS & Android, so travelers can buy and activate eSIMs directly from their phone. Still early, but the goal is simple: Make getting internet anywhere in the world fast and effortless. Building in public. #startup #buildinpublic #traveltech #esim #indiehackers #saas
