Pro tips by country
Bulgaria: Install it when a Bulgarian contact uses it, but ask which channel they prefer. Activate it before travel while your main number can receive a code.
Greece: Install it only when a Greek contact specifically uses Viber. Keep phone, SMS and email fallbacks for urgent coordination.
Myanmar: Share your Viber number when coordinating with local contacts. Many won't have WhatsApp.
Serbia: Most Serbians use Viber instead of SMS. Always try Viber first when contacting locals.
Ukraine: Join public Viber communities for cities you're visiting. Locals post real-time shelter locations and curfew updates.
