Mobile application
Nimra Mobile
A full phone line in your pocket — calls, SMS, and an eSIM built into a native mobile app. No physical SIM required.
Summary
Where the browser extension puts a phone line in Chrome, the mobile app puts one in your pocket. Native Flutter build: calls, SMS, eSIM provisioning, and contacts — all without a physical SIM. One number, any device.

What Was Built
Overview
The mobile app is a different product entirely. eSIM provisioning means users get a real number without a carrier or a SIM card. Calls and SMS run natively on device. Built in Flutter — one codebase, iOS and Android.

iOS + Android
Problem
eSIM provisioning on mobile is a different beast from WebRTC in a browser — carrier-level integrations, device profiles, and platform-specific APIs across iOS and Android.
Approach
Flutter handles the cross-platform layer. The eSIM flow abstracts the provisioning complexity behind a clean activation screen. Supabase ties the mobile app and the browser extension to one account and one number.
Outcome
In active development. Both surfaces — browser and mobile — share the same backend and phone number, making Nimra a genuinely cross-platform communication tool.
