⚠️ Before you start: Make sure you’re on stable Wi-Fi. eSIM installation requires an internet connection to download the profile — it cannot be done offline.

🍎 Installing on iPhone (iOS 12.1+)

Open Settings

Go to Settings → Cellular (or Mobile Data, depending on your iOS version).

Tap "Add eSIM" or "Add Data Plan"

You'll see this option at the top, below your primary SIM.

Scan the QR code

Point your camera at the QR code you received by email. iPhone detects it automatically.

Confirm the eSIM download

Tap "Add Data Plan". The profile downloads in 10–30 seconds.

Name your eSIM

Give it a name like "BleSIM Japan" so you can find it easily.

Set your data line

In Settings → Cellular → Cellular Data, select your BleSIM eSIM as the default data line.

💡 iPhone tip: If you don’t see “Add eSIM”, go to Settings → General → About and look for “EID number”. If it’s missing, your iPhone doesn’t support eSIM.

🤖 Installing on Android (Samsung, Pixel, others)

Open Settings → Network

Path varies by brand: Settings → Connections → SIM Manager (Samsung) or Settings → Network → SIM (Pixel/others).

Tap "Add SIM" or "Download eSIM"

The label varies by manufacturer — look for anything related to adding a new SIM.

Scan the QR code

The camera opens automatically. Point it at your BleSIM QR code.

Confirm the download

Tap Activate or Download. The profile installs in 15–60 seconds.

Set the data line

In Settings → Connections → Data Usage, select your BleSIM eSIM for mobile data.

After installation: 3 important steps

Turn off roaming on your primary SIM — to avoid unexpected charges abroad.
Set BleSIM as your data line — your main number stays active for calls and SMS.
Test the connection — open a browser and load a page. If it works, you’re all set!

Frequently Asked Questions

My QR code isn't working — what should I do?

An eSIM QR code can only be scanned once. If the scan fails, make sure you're on stable Wi-Fi and try again. If the code has already been consumed, contact BleSIM support — a new QR code will be generated at no cost.

Can I install the eSIM before I arrive at my destination?

Yes — and it's recommended! You can scan the QR code at home. The eSIM downloads immediately but only consumes data once activated and used at your destination.

How do I know if my eSIM is activated?

In Settings → Cellular (iOS) or Settings → SIM (Android), your eSIM should appear with a signal indicator. If you're at your destination, you'll see the local carrier name displayed.

Do I need to remove my main SIM?

No. In dual SIM mode, both lines coexist. Just turn off roaming on your primary SIM to avoid accidental charges. Calls and SMS still go through your regular number.
