Why most travel apps still send users to third-party eSIM stores
You built a travel app. Users plan trips, book stays, track itineraries. The moment they need data abroad, they leave your app and go to Airalo or Holafly. You lose the moment of highest engagement and a meaningful revenue line.
Building eSIM connectivity in-house means telecom contracts, multi-country compliance, customer support for install failures, and a six-month integration project. Most travel apps cannot justify the build.
You need eSIM as a feature, not a project.
