I'm currently on IPv4 as of now, but I do see that I could change to 4/6. Maybe I'll give it a shot.Good to know my phone can make the switch though I doubt I'll ever be in a tmo area.
Internet Protocol IPv4 is running out of numbers so enter the replacement IPv6. It will be a long time to switch and both will be in use. In the vzw apn they are listed together: IPv4,IPv6
