No. It is not possible to install one eSIM on several devices simultaneously.
When you activate an eSIM on a device the mobile network provider will register the eSIMs unique identification number (EID) with the device manufacturer. The EID is a unique identifier that cannot be duplicated or shared across multiple devices.
Therefore, you can only use an eSIM on one device at a time. If you want to use the same eSIM on a different device, you would need to uninstall the eSIM from the original device and install it onto the new device.
