Answered: Is it possible to call someone on Viber and it says Ringing eventhough the other person has bad connection or no data?

I use viber extensively.

When it says the message has been delivered, that what it means, delivered to the recipient. You can even set it up so that when the person reads the message it says seen.

If you call the person and does not have signal, it just says calling. But when the person is reachable, it says ringing. If the person answers and the signal is not good it tells you weak signal. If its terrible and the person tries to answers it just says reconnecting
