If you would like to use an eSIM on your device, you will need to check if your device is compatible.
The guide below, shows you how to check if your device is unlocked on Samsung.
1. Go into Settings.
2. Click on "Connections".
3. Go into "Mobile Networks" > "Network Operators".
4. Deselect "Select Automatically".
5. If your device is unlocked, then a list of Networks will pop up in the form of a list as shown below.
If you do not see the list, then your device may be locked to a specific network. You will need to contact your mobile carrier to get your device unlocked. If your device was recently unlocked, you may have to wait for the eSIM support to become available as your carrier might disable it for a period of time for security reasons.
