Read the full description
onesim is a mobile app that gives you one eSIM for every destination. Install it once and keep it: before each trip, pick a package for any of 195+ destinations and it goes onto the same eSIM, so there's no new install or QR code every time. Buying, setup, usage tracking and top-ups all happen in the app in a few taps. We built it for people who travel often and want reliable data at affordable prices, without juggling a different eSIM for every country.

Partial The app and eSIM management UI are easy to vibe-code, but a real 195-country prepaid eSIM service depends on wholesale data plan supply from carriers or aggregators, which is a business and partnership barrier rather than a coding one.
What it would actually take: The app needs an eSIM provisioning backend (GSMA RSP / SM-DP+ or a reseller API from an aggregator) plus payments, plan catalog sync and usage APIs. The hard part is licensing or reselling data across 195+ destinations, which requires commercial agreements with aggregators or MNOs and compliance with telecom regulations. Engineering effort is modest compared to that supply-side work.
