Samsung Galaxy eSIM Installation Steps

Open Settings and tap Connections
Start from the Settings app on your Samsung Galaxy phone. On the main Settings screen, tap Connections. This is where Samsung groups Wi-Fi, Bluetooth, mobile networks and SIM manager settings.
Open SIM manager
Inside Connections, scroll if needed and tap SIM manager. This page controls your physical SIM cards, eSIMs, preferred SIMs and mobile data settings.
Tap Add eSIM
On the SIM manager screen, tap Add eSIM. Your Samsung Galaxy phone will begin the eSIM setup process and look for a way to download your eSIM profile.
Scan your eSIM QR code
Choose the option to scan a QR code, then scan the eSIM QR code provided by your eSIM provider. Make sure the QR code is clear and fully visible. If the QR code is on the same phone, open it on another device or print it first.
Turn on data roaming for your travel eSIM
After the eSIM is installed, go back to SIM manager. Select your travel eSIM for Mobile data, then turn on Data roaming for that eSIM. Most travel eSIMs need data roaming enabled to connect to partner networks abroad.

Yes, in most cases you can install your eSIM before your trip as long as your phone is connected to stable Wi-Fi. Many travelers prefer installing the eSIM before departure so they can connect quickly after landing.
However, the activation rule depends on the eSIM plan. Some plans start when the eSIM first connects to a supported local network, while some may start after installation. Always check your plan instructions before installing.

If QR code scanning does not work, your eSIM provider may also give you manual activation details, such as an SM-DP+ address and an activation code. In the eSIM setup screen, look for an option such as Enter activation code or Enter details manually.
Enter the activation details exactly as provided. A small typo may cause the eSIM setup to fail.
