"We want to enable our users to protect themselves from communication with unknown contacts against the background of frequent cases of fraud through messengers," the statement said.
It is noted that the feature is not enabled by default, and the user decides whether he/she wants to completely ban calls from strangers in Viber or leave this option.
The new feature is already available in the latest version of the platform for all users with Ukrainian mobile phone numbers.
Protection against unwanted calls works on both Android and iOS devices, as well as on the desktop version of the program.
As it was reported, Ukrzaliznytsia was launching its own chatbot with the function of selling tickets in Viber and Telegram messengers.
