Always says activation failed. It's a new phone! I want to transfer viber from my old phone which is already almost unusable. All other apps work well in this new phone. Viber is the only one not letting me register. I tried with another older phone, I get the otp and viber doesn't complain about activation there. What is going on? Update: Any number I input from Bangladesh is giving that activation failure error. Viber, please fix this ASAP!
