My viber contacts are gone, How to recover viber contacts. my contacts are intact

Contact Viber support. This is not an Apple issue.

Go into the app and choose: Deactivate Account.

You will then activate the account the next time you start the app and (hopefully) initiate a sync with your contact list in your iPhone.

This worked for me when I, for some reason, lost all my Viber contacts :-).

Thank you I've been pulling my hair out with this problem. The only thing I didn't do was deactivate account, yes it worked straight away.

Thanks Sean snr
