Frequently asked questions
Is Callana cheaper than Viber Out for international calls?
Rates vary by destination, but Callana is competitive with Viber Out across most popular corridors. The key difference is that Callana is entirely browser-based with no app download required, while Viber Out requires the Viber mobile app. Both offer pay-as-you-go pricing without mandatory subscriptions.
Can I use Callana without downloading an app?

Does Callana support caller ID like Viber Out?
Yes, Callana supports caller ID on outbound calls. Viber Out does not display your caller ID to the person you are calling, which means your calls may show up as an unknown number. With Callana, recipients can see who is calling, making it more likely they will answer.
