[iMore Question]

I am using viber in iPhone while I did blocked a contact number but still that same number calling me in viber.

Hello there, and good morning.

While I'm not familiar with Viber, I do use Google Voice. If I block a number on my iPhone, that same number can still call my GV number unless I block it there too. Do you have that number blocked on your iPhone and in Viber?

I'm not familiar with Viber, but it sounds like you need their customer support; https://support.viber.com/
