About this app

KEY FEATURES

Scan to open your device's eSIM setup
Just scan the QR code from your purchase email. No typing
activation codes, no jumping between apps — your phone's "Add eSIM"
screen opens for you.

18 illustrated setup guides
Step-by-step guides for iPhone and Android (multiple
manufacturers), plus common troubleshooting and error-message references — all written for non-technical users.

Available in 5 languages
Japanese, English, Simplified Chinese, Traditional Chinese, and
Korean. Choose your language at first launch or switch anytime.
Built for travelers and international users.

Built-in chat support
Stuck on a step? The in-app assistant answers your questions
instantly.

Fallback for older devices
On devices where auto-launch isn't available, the app shows a
manual setup screen with copy-ready codes.

PLEASE NOTE
This app does NOT sell or issue eSIM plans. It is a
setup-assistance tool for users who have already received a QR code or activation code (typically by email after purchasing an eSIM from another service).

REQUIREMENTS
- An eSIM-capable smartphone (iPhone XR / XS or newer, or a recent Android device)
- A QR code or activation code from your eSIM provider
