Guess few of you would have searched for the way to use your SIM Card slot in Dell XPS or any other laptop devices(Check the manual for the slot to insert the SIM).
Having SIM Card slot is not enough to use the SIM Card for connecting to internet, you should check the availability of the WWAN(Wireless Wide Area Network) hardware in the device. Attached the snap of a Dell XPS15 showing the place where you can find the slot to install the device.
If the device is already install, you can use the SIM card slot right away after installing the necessary drivers.
