Plenty of laptops have the SIM slot, as it is part of the case, but not the WWAN card or antenna. All you need to do is to remove the back cover to know for certain if you have a WWAN card and antenna. It likely needs just a single Phillips #1 head screwdriver, plus something to pry the edges of the cover such as spudger or guitar pick. If your laptop does not have the antenna, your easiest solution would be an external USB WWAN adapter.
Hello! I own a Dell Latitude 7390 which has a built in SIM card slot. I have a sim card inside it at the moment and I don't see the Cellular option anywhere. What do I do?
