Hi there i hope someone can help me. I gave my old mobile to my son. Samsung S8. He put his sim card in this phone. Since he downloaded viber this is for some reason connected to my viber on my new devise. For some reason some of my contacts (not all) they call my number on viber but is ringing on my sons phone and he answers! if they send me a viber message I get it and not my son though! We have no idea how this has happened and how to fix it!
