My vision of a   5G Linux Cellular Laptop is a a 5G Laptop running Linux Operating System ( e.g. Ubuntu Touch ) which have an embedded 5G modem chipset ( like for example the Fibocom FM350-GL chipset )  and has a  5G SIM Card Slot that can accomodate a  5G SIM card  and when we subscribe to a Cellular Data  Plan  which comes with a  telephone number or a personal phone number ,  we should be able to  make telephone calls and receive telephone calls directly from our 5G Linux Laptop just like a 5G smartphone .   Phone calls can be taken directly from our  Linux  5G laptop , just like a 5G smartphone . No tethering [ 1 2 ] required . No  Microsoft Phone Link software required . No 5G smartphone required .  

Your Laptop is your Smartphone !   

Your  Linux  5G  Laptop is your  Linux  5G  Smartphone !
