T_mobile has been running TV ads daily stating they are the only company that currently has a nation wide 5G network.
I have no reason not to believe them.
The deception is in the word ‘network’.
That is the same for ALL G’s: 1,2,3,4,and 5.
It’s when the signal flies thru the air from the towers to the phones/receivers that is only slightly implemented at this time.
