No, it is not possible to install one eSIM on several devices simultaneously. An e-SIM (embedded SIM) is a digital SIM that is embedded in a device and can be programmed with information from a mobile network.

When you activate an e-SIM on a device, the mobile network provider registers the e-SIM’s unique identification number (EID) with the device’s manufacturer. The EID is a unique identifier that cannot be duplicated or shared across multiple devices.

Therefore, you can only use an e-SIM on one device at a time. If you want to use the same e-SIM on a different device, you would need to deactivate it on the first device and then activate it on the new device.
