The New eConnect Japan SIM App Is Here

Last week we've released the latest version (v5.0) of eConnect Japan SIM app for both iOS and Android.

This update introduces a fresh new look, an intuitive user interface, and an enhanced SIM registration process.


We've made significant changes in this release, particularly focusing on design and the SIM registration flow.

A Sleek, Intuitive Design

The new version of our app comes with a complete design overhaul / look, providing a cleaner and more user-friendly experience.

We've also incorporated our latest brand colors into this release, seamlessly aligning it with our website and web app (was long overdue...).

App screens on iPhone 14 Pro

We hope that our customers using eConnect Japan Prepaid SIM cards find this new version easy-to-use and visually-appealing, making the use of our SIM card a joy.

Improved SIM Registration Process

With this update, we've made the SIM registration process easier than ever, making sure you'll have your SIM card(s) added in no time.

There are three ways to add / register your SIM in the app.

1️⃣ Manually enter the SIM numbers

2️⃣ Scan the barcodes on the back of SIM card frame (tap the camera icon)

3️⃣ Use Add SIM button in the shipping confirmation email (*coming soon)

The SIM numbers (MSISDN and Serial Number) will be provided in the shipping confirmation email once it's shipped. You can also find them on the back of the SIM card frame, along with the barcodes.
