Simzzy

An eSIM store that provisions itself.

Overview

A fully automated eSIM vending platform, integrated with an eSIM provider API for live plan data and order placement, and with a payment gateway for checkout. The platform provisions and delivers the eSIM without anyone touching the order, and gives the operator an admin panel over the business behind it.
