This is a representative of Viber Media.
The problem you are describing could be due to being behind a firewall, or being blocked by your cellular provider.
1. What country are you located in? Which cellular network?
2. Try opening the following ports:
TCP: 5242 + 4244
UDP: 5243 + 9785

Since I do not have access to my universities WiFi settings and cannot open the ports, I was wondering if there is a way for me to bypass the firewall blockage? (for example through connecting via VPN)
Your assistance is appreciated.

This reply doesn't have all information needed to enable Viber through a firewall. This looks like destination port information only. You should specify both source and destination ports since I doubt the IT guys will accept open the entire port span for source ports? Please specify the firewall settings as:
UDP source port(s)
UDP destination port(s)
TCP source port(s)
TCP destination port(s)

We have already specified the ports.
Please see our original response in this thread.
If your network administrators refuse to enable these ports, then unfortunately there is nothing we (Viber) can do to help
