Ok, something to report.
My 3g data stopped working, it took a phone reboot to finally get it back.
Leading up to issue:
I have little to no cell service in my office, i use the phone on wife all day long.
I left the office for lunch.
Received a phone call
After the phone call (while out of the office, and in decent cell coverage), i noticed that my 3g data was not working.
I did not notice whether data was working before the call or not.
What was tried to resolve the issue:
put the phone in airplane mode for 10 seconds, and back out. - no help
set the phone from CDMA to CDMA/LTE and back again. - no help (i keep the phone in CDMA mode because i do not have LTE coverage in my area).
Rebooted phone - 3g was restored after the reboot.
