Viber only works with WIFI not over 3G/LTE network
Hello, I have an Iphone 7, and I install Viber to chat with some friends, I usually only use Whatsapp, but this looked ok. Now that I have it on my phone, I can only chat while I am connected to a Wifi connection. While I am out of WIFI, using my data plan, which is very big, it doesnt work. I am from Guatemala and my provider is TIGO.
Can someone help me and tell me what is wrong? I have deleted the app various times and reinstalled it, and is the same issue.
iPhone 7, iOS 10.2.1
