This ones throwing me for a loop 
Turbo has been brilliant aside from one tiny issue that i'm only now realizing...
Upon Receiving an incoming call my phone rings & vibrates - but will not display any alert on the screen (or lock screen) that there is an incoming call. If I unlock the phone as it's ringing the normal home screen is displayed and after a ring or two I receive the below "Mobile Data not available" prompt. Pressing ok results in the phone going back to the homescreen with once again, no further dialog to answer/ignore/mute the call (nothing in the notification bar either). Eventually the call will make it to voicemail as i can't answer it, and i get a prompt missed call notification.
Items i've checked so far:
disabled apps - re-enabled to make sure nothing got zapped that's interfering
Mobile data is enabled under settings
OTA Update was applied & Phone works fine otherwise, solid 4G service in populated area......
Thoughts/ideas?
TIA!
Note the missed call notification icon is displayed from a previous call when i was trouble shooting:
