Human Factors
The Pilot Flying and I had a normal push back; taxi; and take off. No deviations from training or FOM/AOM SOPs were noted by me at anytime during the flight. After turning to a heading of 190 degrees; it seemed like we were on the Tower frequency for a longer than usual time (no quick hand-off to departure). I thought I missed a radio call; and more than likely switched to departure without direction from the Tower. This was my second sequence since being released from IOE. I was displaced from ZZZ1 to ZZZ and I'm still learning how the ATC system works in ZZZ . Prior to joining [Company]; I flew out of ZZZ2.  I'm still learning ZZZ's operation. I should have asked the Pilot Flying if he thought I missed a call. This would have been an opportunity for me to learn how ATC works in ZZZ.
Airline First Officer reported lost com; NORDO; with ATC due to being unfamiliar with the local operation.
