Viber business messages

Fully branded messages — your logo and company name, with images, tappable buttons and carousels. Template messages go out at a special rate.

FlashCall

Verify a number with a missed call instead of an SMS. Same result, noticeably lower cost per verification.

Why us

Why clients choose us

Direct routes, no middlemen

We connect straight to Ukraine's mobile operators, with no aggregator sitting in between. That means higher delivery rates, lower latency and a better price than second-tier resellers can offer.

One API for everything

Integrate once, then run SMS, Viber, FlashCall and chatbots from the same endpoint or the same dashboard.

Data security

  • Two-factor authentication
  • Role-based access to data
  • Audit log of user actions

15 years of integrations, however complex

We know how each industry works — banking, retail, healthcare, logistics. We handle the standard scenarios such as OTP and bulk campaigns, and the non-standard ones that need an architecture designed around them.
