If we are accustomed to making phone calls and receiving phone calls  on our Smartphone , on our Tablet , and miss it very much when we pick up our Laptop , so , making a phone call by dialing a phone number on the 15.6 inches Touchscreen of our 5G Laptop and receiving a phone call directly on our 5G Laptop   should be very exhilarating . It is a pretty great feature because we do not have to carry a Smartphone or purchase a Smartphone [ 1 ] .   With the advent of IoT and 5G , as of today , April 2022 , just having a standard/traditional Laptop or a 5G Laptop with no phone functionality like a 5G  smartphone, is not always the best solution . Implanting a data radio and a SIM/eSIM inside a Laptop or connecting a Laptop to a 5G USB Dongle so that these Laptops have  phone functionality just like a 5G Smartphone is the best option . The possibility of all    5G/4G LTE   Laptops (fitted with SIM/nanoSIM/eSIM) and  5G/4G LTE   PCs (fitted with SIM/nanoSIM/eSIM) and  4G LTE/5G  Tablets (fitted with SIM/nanoSIM/eSIM) getting a built-in cellular connectivity that can do voice calls just like a Smartphone , should be welcoming , should be applauded. This is to maximize the full potential of 4G LTE and 5G on a Laptop . The sooner this kind of cellular Laptop arrive on our shores , and the  more people start using it , the sooner we can start to get a price reduction on this kind of machine , on this kind of Cellular Laptop .
