A  5G USB  Modem/Dongle with   phone/telephone functionality that I envisioned look something like   this or  this  or  this  and it has  a  built-in 5G modem [ 1 ]  just like any other 5G USB  Modem/Dongle  that is sold in the market today and it support various major Operating Systems, like for example Windows Operating System , Linux Operating System and  Android Operating System .    The 5G USB  Modem/Dongle with   phone/telephone functionality that I envisioned   when plugged or inserted into any traditional  PC/Desktop or any  traditional Laptop or any traditional Tablet  that do not have a 5G connection , the  5G USB  Modem with phone functionality that I envisioned ,  will automatically create  a  phone dialer , and  we can  make phone calls and reply phone calls just like a 5G smartphone using voice over 5G ,  directly on that PC/Desktop  or   directly on that Laptop   or   directly on that Tablet   and  at the same time we are able  to access Internet at 5G speed [ 1 ]  , without the need to configure the 5G USB Dongle , without the need to configure the 5G USB Stick .  The  5G USB  Modem/Dongle with   phone/telephone functionality that I envisioned  has this plug-and-play  convenience , meaning , it automatically recognize and automatically configure , regardless of the Operating being used  inside that   PC/Desktop , or Laptop or Tablet .
