The issue for me was watchdog configured to monitor wlan0 interface. So when I turned on the PI without connecting it to wifi I have received following logs in "journalctl -f":
watchdog[781]: device wlan0 did not receive anything since last check
watchdog[781]: Retry timed-out at 61 seconds for wlan0
watchdog[781]: shutting down the system because of error 101 = 'Network is unreachable'
And because of that ppp0 did not have time to boot and initiate connection to cellular data provider.
After changing it from interface = wlan0 to interface = ppp0 Everything work flawlessly.
Thanks
