Here is a short video that I manage to stumble on the Internet , correct me if I am wrong , that says , "Stop reaching for this when you already using this" .  From my observation , it seems that in this video ,  a Smartphone(regardless whether it is 5G or 4G) , is not required when you are already using a Windows 11 machine , like for example a  Windows 11 Laptop.   

I am a  15.6 inches screen size advocate and by looking at the short video clip , in my opinion , the Windows 11 machine the lady is holding or carrying could be :

1. a    15.6 inches  Windows 11  "Touchscreen"  "360 degrees foldable"  Laptop 

2. a   15.6 inches  Windows 11  "detachable"  Laptop 

Anyway , in my opinion , that kind of video clip will be a good and awesome  promotional video for  a  Windows 11 machine that have  telephone/phone  functionality like a 5G smartphone , regardless whether it looks like a Laptop or it looks like a Tablet or it looks like a Smartphone , so much so that we don't have to rely on a 5G smartphone totally, we don't have to hang on a 5G smartphone totally because we can make  telephone calls and receive telephone calls directly on our Laptop or on our Tablet.  These  Windows 11 machines with  telephone/phone   functionality like a  5G smartphone , that I envisioned , look something  like  this  or  this or  this or  this .

As of today  August 2025 , I believe a device like this and Windows 11 machines like this  or  this or  this or  this , is still on the horizon!
