My  idea   or  vision/version   of a  15.6 inches "360 degrees foldable"   5G  Cellular Laptop(so that we don't have to rely on a 5G smartphone)[ 1 2 3 4 5 ] _  Basically , it is a  5G  Laptop but It is not like the 5G Laptop that is sold in the market today  in January 2025 , which have no phone functionality like a   5G smartphone. Today , there are   software/apps  that can help us to make phone calls directly from our 5G Laptop but we got to have a 5G smartphone and a 5G Laptop in order to do that . That means having to buy a 5G smartphone and having to buy a 5G Laptop in order to do that. But if we have  a  5G  Cellular  Laptop  that I envisioned  that can make telephone calls and   answer/reply   phone calls directly on them , without the need of a 5G smartphone , without having to rely on a 5G smartphone, without the need to  buy/purchase  a 5G smartphone ,  without the help of a 5G smartphone , it would be great.  The 5G Cellular Laptop , that I envisioned , is thin and light and slim and sleek ,   " 360 degrees foldable "  or      "detachable" , can  "auto-rotate"  in LANDSCAPE MODE or  PORTRAIT MODE , and have a       " touchscreen " , and have a  15.6 inches screen size  .   As for me , I would still prefer a 5G Cellular Laptop that is     "360 degrees foldable"  because a   "360 degrees foldable"  5G  Cellular Laptop  can be converted into a 5G  Cellular Tablet swiftly (without detaching the screen like this  or  this )  and can be operated in various mode as shown here and  here  .  The 5G Cellular Laptop that i envisioned must have a built-in  DVD-RW  Player [ 1 2 ] , preferably  INTEL-based    SoC/processor/microprocessor  running  INTEL-based  Windows 10 Operating System 1 (not ARM-based      processor/SoC     running  ARM-based Windows 10 Operating System), with built-in 5G modem [ 1 2  ]  and has  a   5G    SIM /  nano SIM   Card  Slot   or  eSIM , that 5G Cellular Laptop must have a phone dialer and when we subscribe to a  Cellular Data Plan [ 1 ]  from an Internet Service Provider  that come with a phone number or a personal phone number , we can dial a phone number on the 5G Cellular Laptop 15.6 inches  Touchscreen  just like what we do on a 5G smartphone , so much so that we can use that 5G Cellular  Laptop to make phone calls to someone or to anyone or to a  landline telephone  using   his/her   phone number  and we can use that  5G  Cellular Laptop  to   answer phone calls  from someone or  from  anyone or from a   landline telephone , directly on that 5G Cellular Laptop ,  just like a  5G smartphone .  No 5G smartphone needed because we do nt have to rely on a 5G smartphone for phone functionality .  Furthermore , the 5G SIM Card of  a 5G Cellular Laptop(regardless of the Operating System being used , regardless whether it is INTEL-based or  ARM-based) , that i envisioned , must be interchangeable and can be swapped back and forth with another  5G Cellular Laptop or with another 5G smartphone or with another 5G tablet(phone/telephone  calling Tablet) ,  or with a 5G USB  Dongle/Stick , meaning , a 5G SIM Card from  a  5G Cellular Laptop when  inserted into a traditional 5G Laptop (a 5G Laptop with  no    phone/telephone   functionality) or a 5G smartphone or a 5G tablet(phone/telephone   calling Tablet) , that 5G SIM Card can be use to make phone calls and reply phone calls on that traditional 5G Laptop (a 5G Laptop with no  phone/telephone    functionality) , on that 5G smartphone , and on that 5G tablet(phone/telephone calling Tablet) and  simultaneously surf the Internet at breakneck speed with our 5G smartphone and our 5G tablet using the 5G network.  There is no need to subscribe to 3 different Cellular Data Plan in order to have 3 different 5G SIM Card , one 5G SIM Card for the 5G Cellular Laptop , another 5G SIM Card for the 5G smartphone , and another 5G SIM Card for the 5G tablet. We just subscribe to one  Unlimited Cellular Data Plan with 5G and with one  5G SIM Card and with one Phone Number , we can use it for our 5G  Cellular Laptop and our 5G smartphone and our 5G tablet .  Sometimes we do not want to make a VoIP  call using a Mobile App like WhatsApp , Skype , Zoom , etc., etc., on our 5G Cellular Laptop , we have a phone number from someone  and we just  want to dial that phone  number on our  5G Laptop 15.6 inches Touchscreen ,  just like we do on a  5G smartphone .  With   a   5G Cellular    Laptop which I envisioned   ,  we should be able to use our 5G Cellular  Laptop  as a full featured   phone/Smartphone ,  just like a  5G  smartphone.  Since that kind of  5G Cellular  Laptop  is   "360 degrees foldable " , that  5G Cellular  Laptop can  serve as  a  Laptop , it can serve as a  Tablet and above all or BEST OF ALL , it can serve as  a   5G  Smartphone .  Meaning , we can make phone calls and answer phone calls directly on that  5G Cellular  Laptop , just like a  5G  smartphone , either in  LAPTOP MODE or  in  TABLET MODE or in  TENT MODE or in  STAND MODE .  In my opinion , as of today January 2025 ,  with the advent of 5G , IoT , nanotechnology , neural networks and AI , implementing  a  voice/telephone-calling feature (just like a  5G smarttphone) in a Laptop and calling it  a  5G Cellular Laptop , is not  an extra fancy feature anymore   and it should be standard in all 5G Cellular Laptops sold in the market today  , regardless of the Operating System being used , regardless whether it is INTEL-based or  ARM-based , regardless of screen size , regardless whether it is  "360 degrees foldable"   or           "detachable".
