Should Greek businesses use Viber or WhatsApp in 2026?
For Greek residents, Viber is typically the primary messenger (industry reports cite ~90% smartphone penetration). Use Rakuten Viber commercial bots + Business Messages for local CRM, retail promos, booking reminders, and support. For tourists and many international guests, add WhatsApp via a Cloud API BSP such as Ominiflow. Same CRM, channel preference by contact country/language.

Greek consumers live on Viber. Infobip and similar country messenger charts routinely list Greece among the markets where Viber penetration approaches 90% of smartphone owners — alongside Bulgaria, Serbia, and Belarus. Hotels, ferries, pharmacies, banks, and D2C brands that only chat on Instagram DMs leave money on the table.
