We would suggest that you try:
(1.) Settings > Network & internet > SIM card> Disable and enable the SIM card
(2.) Settings> Network & internet > Mobile network > Preferred network type> choose "2G/3G/4G" again.
(3.) Power off your phone > reinsert sim card > turn on the phone
(4.) Turn on airplane mode > wait for 3 seconds > then turn it off.
(5.) Try using another sim card by a different operator
(6.) Try resetting the network settings: Settings > System > Reset options > Reset WiFi, mobile & Bluetooth)
(7.) Please make sure to update to the latest firmware version WW-16.0615.1910.112.
