## Description

OneSIM is a dedicated management app that allows users to log in with an account issued by a partner dealer to easily view their data plans, usage details, and eSIM/SIM status. Without any sign-up or payment process, users can securely check their existing SIM information and submit requests for plan changes or data top-ups directly through the app.

Plan Overview
View detailed information about your purchased data plan, including validity period, available data, and remaining balance—all in one place.

Real-Time Data Usage

Plan Change & Data Top-Up Requests
