An eSIM allows you to connect to the internet using a cellular data connection without the need for a physical SIM card. To use an eSIM on your laptop, you will need a PC running Windows 11 and a PC that has an eSIM capability. Check if your PC has an eSIM by going to Settings > Network & internet > Cellular. If your PC has an eSIM, you can add an eSIM profile to connect to the internet using cellular data.
