SimFuse

SimFuse is a travel connectivity platform that makes it easier to stay connected abroad with digital eSIM data plans. Travelers can explore plans for individual countries, regions, and multi-country trips, install an eSIM digitally, monitor data usage in real time, and top up eligible plans without reinstalling their eSIM. The free iOS and Android app also offers eSIM management in one place and an optional paid VPN service. SimFuse additionally supports AI-agent workflows through an MCP interface for discovering plans, checking coverage, and preparing checkout sessions.
