How to Scan a QR Code to Activate Your eSIM — iOS & Android Guide
Share
You just bought your AloOui eSIM and received your QR code by email. Now what? Activating your eSIM takes less than 5 minutes — no store visit, no SIM card, no waiting. Just scan, tap, and you’re connected.
What Is eSIM QR Code Activation?

An eSIM (Embedded SIM) is a digital SIM built into your phone. Instead of inserting a plastic card, you activate a mobile plan by scanning a QR code — your device downloads the carrier profile automatically.
Why QR code activation?
- ⚡ Speed — your plan is active in minutes, not days
- 🔒 Security — no manual typing, all settings auto-configured
- ✈️ Travel-friendly — activate before you board, connected the moment you land
- 📱 Dual SIM — keep your home number active while using your travel eSIM
How to Activate eSIM on iPhone (iOS)
Works on iPhone XS and newer. Make sure your iPhone is unlocked and connected to Wi-Fi before starting.
- Go to Settings > Cellular > Add Cellular Plan
- Scan the QR code from your AloOui confirmation email
- Confirm the plan and label it (e.g. “Travel” or “AloOui”)
- Enable the new line and restart if prompted
Tips for smooth iOS activation:
- Keep Wi-Fi on throughout the setup
- Maximize screen brightness if scanning from another device or printed page
- If the QR won’t scan, clean your camera lens and ensure the code isn’t blurry or folded
- If activation stalls, toggle Airplane Mode on/off or restart your iPhone
How to Activate eSIM on Android

Works on Samsung Galaxy S20+, Google Pixel 3+, and most modern Android phones. Steps may vary slightly by brand.
- Open Settings > Connections > SIM Manager (or Network & Internet > SIMs on Pixel)
- Tap Add Mobile Plan > Scan QR Code
- Point your camera at the QR code until your device detects it
- Follow the prompts to download and enable the eSIM
Tips for Android activation:
- Stay connected to Wi-Fi during installation
- Some models require a reboot after adding the eSIM
- QR not scanning? Clean the lens and check the code hasn’t expired
- No signal after activation? Toggle mobile data off and on, or restart
- Most providers (including AloOui) offer a manual activation code as a backup
Troubleshooting: Common eSIM Activation Issues
Even with simple QR activation, issues can arise. Here’s how to fix the most common ones:
- QR code won’t scan — increase screen brightness, print the QR on white paper, or clean your camera lens
- eSIM shows “No Service” — restart your device, ensure Wi-Fi was on during activation, and check your plan is active
- QR code already used — QR codes are single-use; contact AloOui support to get a new one issued instantly
- Activation stalled — toggle Airplane Mode on/off, or try again after a full restart
- Phone not compatible — check that your device is unlocked and eSIM-compatible before purchasing
