Prelude adds Viber as an OTP Solution

We're excited to announce the addition of Viber as our newest channel for OTP messaging, complementing our existing channels: SMS, WhatsApp, and RCS. This integration promises better conversion rates, more cost-effective routing, and reliable message delivery in regions like Eastern Europe and Asia.

What Will Change?

Improved Conversions: Direct messaging through a familiar app boosts customer engagement.

Lower Costs: You'll benefit from this cost-effective route directly, as we don't add any markup to the message fee. For example, in Ukraine, Viber costs $0.0075 compared to SMS at $0.1255.

Reduced Fraud: Messages via Viber are immune to International Revenue Share Fraud (IRSF).

How to start using Viber for your account?
