How to Take a QR Code Screenshot

If you're viewing the QR code on the same device you're installing on, take a screenshot first:

  2. Press and hold the Power + Volume Down buttons simultaneously
  3. Release when you see the screenshot animation or hear the shutter sound

📱 Alternative Screenshot Methods: Some Galaxy models use Power + Home, Palm Swipe, or S Pen screen write. Check your device's screenshot settings if the button method doesn't work.

Complete QR Code Installation Process

Now that you have your QR code ready (either displayed on another device or saved as a screenshot), follow these step-by-step instructions to install your eSIMfo eSIM on your Samsung Galaxy device.

Open Device Settings

Launch your Samsung Galaxy Settings app. You can access it by swiping down from the top of your screen and tapping the ⚙️ gear icon, or by finding the Settings app in your app drawer.

Select Connections

In the Settings menu, tap Connections to access all wireless and network settings for your device.

Open SIM Manager

Tap SIM manager (or SIM card manager on some Galaxy models) to access your SIM management interface.

Select Add eSIM

In the SIM manager screen, tap Add eSIM (or Add mobile plan) to begin the eSIM installation wizard.

Choose Scan QR Code

Tap Scan QR code to activate your device's camera for QR code scanning.

💡 Camera Permission: If prompted, allow camera access for the Settings app. This is required for QR code scanning.

Scan Your QR Code

Now you have two scanning options:

Option 1: Scan from Screenshot (Recommended)

  1. Look for the Gallery icon 🖼️ or Photos icon in the bottom corner
  2. Tap the icon to open your device's photo gallery
  3. Select your QR code screenshot
  4. The system will automatically detect and scan the QR code

Option 2: Direct Camera Scan

  1. Point your Galaxy's camera at the QR code displayed on another device
  2. Hold steady and center the QR code within the scanning frame
  3. Wait for automatic detection (usually 2-3 seconds)
  4. The system will process the QR code information

Confirm and Add eSIM

After successful QR code detection:

  1. Review the eSIM details that appear on screen
  2. Tap Done to proceed
  3. Tap Add (or Install) to confirm installation
  4. Wait while your Galaxy downloads the eSIM profile

⏱️ Installation Time: The download typically takes 1-3 minutes. Keep your device connected to Wi-Fi and don't close the Settings app during this process.

Wait for Activation

Your Samsung Galaxy will now activate your eSIMfo eSIM. During activation:

  • ✓ Keep your device connected to the internet
  • ✓ Don't switch apps or lock your screen
  • ✓ Wait for the "eSIM added" confirmation message
  • ✓ Look for your carrier name or "eSIM" label in the status bar

✅ Activation Complete!

Once you see signal bars and your carrier name, your eSIMfo eSIM is successfully installed. Proceed to the next section to enable mobile data.

Connect to Mobile Data & Configure Settings

After installing your eSIMfo eSIM, you need to enable mobile data and configure network settings to start using your data plan. Follow these final configuration steps.

Check Your Plan-Specific Settings

Each eSIMfo plan may have unique connection requirements. Find your specific instructions in the app:

  • Path 1: My eSIMs → Your eSIM → View Details → How to use your eSIM → Connect to a network → How to connect
  • Path 2: My eSIMs → Your eSIM → View Installation Instructions → Page 2 of 2

Enable Mobile Data on Your eSIM

  1. Open Settings → Connections
  2. Tap Mobile data (or Mobile networks)
  3. Select your eSIMfo eSIM as the active data source
  4. Verify the toggle is turned ON (switch should be blue/green)

📱 Dual SIM Users: If you have both a physical SIM and eSIM, make sure you've selected the correct SIM for mobile data. You can choose which SIM to use for data, calls, and messages in SIM manager settings.

Enable Data Roaming (If Required)

Most international eSIMfo plans require data roaming to be enabled. Don't worry—you won't incur roaming charges with prepaid eSIM plans.

  1. Stay in Mobile data settings
  2. Find the Data roaming toggle
  3. Turn it ON (switch turns blue/green)
  4. Confirm any security warnings that appear

⚠️ Important: Check Your Plan Requirements

Always verify roaming requirements in your eSIMfo connection instructions. Some regional plans don't need roaming, while international plans typically do. With eSIMfo prepaid data, roaming is included—no surprise charges!

Update APN Settings (If Needed)

APN (Access Point Name) settings are usually configured automatically. However, if you experience connection issues, you may need to update them manually:

  1. Go to Settings → Connections → Mobile networks
  2. Select Access Point Names
  3. Tap Add (+ icon) if APN isn't auto-configured
  4. Enter the APN details from your eSIMfo connection instructions
  5. Tap Save
  6. Select the new APN as active

📋 Where to Find APN Details: Your specific APN settings are provided in the eSIMfo app under your eSIM's connection instructions (Page 2 of installation instructions). Most plans auto-configure, so only update if you have connectivity issues.

Verify Your Connection is Working

Confirm your eSIMfo eSIM is connected and working properly:

  • ✅ Signal Bars: Check for 4G/LTE/5G indicator in status bar
  • ✅ Carrier Name: Your network provider should be displayed
  • ✅ Roaming Icon: Small "R" or roaming triangle may appear (this is normal)
  • ✅ Internet Test: Open a web browser and load a page
  • ✅ App Connectivity: Test WhatsApp, email, or social media

⏱️ Connection Delay: It may take 30-90 seconds after enabling data for your connection to fully activate. If no connection after 5 minutes, restart your device and toggle airplane mode ON/OFF.

Frequently Asked Questions

Which Samsung Galaxy models support QR code eSIM installation?

QR code installation works on all eSIM-compatible Samsung Galaxy devices including Galaxy S20/S21/S22/S23/S24 series, Z Fold 2/3/4/5/6, Z Flip/3/4/5/6, and select A-series models. Your device must run Android 9.0 or later and be carrier-unlocked. Check our compatibility guide for your specific model.

Can I scan a QR code from a screenshot on the same device?

Yes! This is the recommended method for most users. Take a screenshot of your eSIMfo QR code, then during installation tap the Gallery/Photos icon in the QR scanner to select your screenshot. This method doesn't require a second device and is actually faster than direct camera scanning.

How long does QR code installation take on Samsung Galaxy?

eSIMfo QR code installation typically takes 1-2 minutes on Samsung Galaxy devices with stable internet. QR code scanning is instant, and profile download usually completes within 60-90 seconds. Network registration may take an additional 30 seconds. This is the fastest installation method available.

What should I do if my Galaxy camera won't focus on the QR code?

Try these solutions: (1) Clean your camera lens, (2) Move to a brighter location, (3) Adjust distance from QR code (try 6-12 inches), (4) Increase screen brightness of the QR code display, or (5) Use the screenshot method instead of direct scanning. If camera issues persist, use our manual installation method which doesn't require a camera.

Can I use the same QR code multiple times or on different devices?

Limited reuse: eSIMfo QR codes can typically be used multiple times during the validity period, but you can only have one active installation per eSIM plan. If you delete the eSIM from your device, you can reinstall using the same QR code. However, you cannot install the same eSIM on two devices simultaneously. Check your eSIMfo dashboard for installation limits on your specific plan.

Why ismy eSIM installed but showing no signal or "No Service"?

If your eSIM installed successfully but shows no signal, check these common issues: (1) Ensure mobile data is enabled for your eSIM, (2) Turn ON data roaming if required by your plan, (3) Verify you're in a coverage area, (4) Toggle airplane mode ON/OFF to force reconnection, (5) Restart your device, and (6) Check if APN settings need manual configuration. Find your plan-specific requirements in the eSIMfo app connection instructions.
