There is a message doing the rounds on Viber claiming to be changing the service which is free to cost you money down the road which amounts to little but nonetheless its just worth pointing out that you should ignore the message regardless.The message will then ask you to forward it onto other people in your directory. IF YOU GET THIS SHARE THIS AND WARN OTHERS.
We have contacted Viber today on Twitter to clarify the matter and since this other users have also experienced the same issue,if i remember this happened last year too at some stage and died off and now it seems its become a problem again,the time of year it is you all should be vigilent to any form of strange messages,infact i had my own email compromised last night too so take all forms security possible to reduce the risk of been caught out.
Just be sure as mentioned above we contacted Viber and they replied quickly which was good of them.
Here is the message we received today,just delete the message and ignore it..Viber is not changing its service or charging as outlined in their tweet above,there is no links in this particular message but should you get it or a message like it containing a link remove it straight away.
This would be considered an on/off issue on Viber but some may have not heard about it and some perhaps did,however its worth pointing this out so you are aware of it and can deal with it and stop it from spreading.
