First you must know the APN means. APN or Access Point Name is the name for the settings your phone reads to set up a connection to the gateway between your carrier's cellular network and the public Internet.
To configure the settings of your 5G network, open phone settings, click "wifi and network"
Open "Mobile Network" setting
Open "Access Point Name (APN)" setting
Select 3dot on upper right and click new. Like this when you select it.
Now configure all the details and get the details here
