How to Install and Activate eSIM on iPhone – Step Guide 2025

Open Settings on Your iPhone

Navigate to Settings on your iPhone and tap on "Cellular" or "Mobile Data".
Select "Add eSIM" and then choose "Use QR Code".
Scan the eSIM QR code from the printed code or another device displaying the code.

Note: For iPhones running iOS 17.4 or later, you can long-press a QR code received via email or on a webpage and select "Add eSIM" directly.

Tap "Continue"

Tap "Continue" and wait up to 10 minutes for the eSIM to activate.
Once activated, tap "Done".

Label Your eSIM on iPhone

You can rename your eSIM for easier identification.
Tap the > icon and select a preset label or enter "Simbye" in the Custom Label field.
After labeling, tap "Done" and then "Continue".

Set Your Default Line

Set the Default Line to "Primary" and tap "Continue".
Ensure iMessage & FaceTime are also set to "Primary" and tap "Continue".
For Mobile Data, select the previously chosen eSIM label.

Important: Keep "Allow Mobile Data Switching" turned off to avoid extra roaming charges.
It’s best to activate your eSIM only at your destination to prevent any data usage before your trip.

Activate Your eSIM

After installation, go back to Settings.
Navigate to "Mobile Service".
Select your eSIM from the list.
Turn the line "On".
Set "Data Roaming" to "Online".

Important: Perform this step only when you have arrived at your destination country to ensure optimal connectivity and avoid unnecessary roaming charges.
