About this listen
OTP delivery isn’t always reliable across African telecom networks. Messages can be delayed, filtered, or missed entirely, leading to failed verifications and user drop-offs.
In this episode, we explore how Voice OTP solves these challenges by delivering verification codes through automated calls instead of SMS. By using telecom voice routes, businesses can ensure faster delivery, higher answer rates, and more consistent verification outcomes.
We also break down when to use Voice OTP, how it works alongside SMS as a fallback layer, and why it’s becoming essential for fintech, e-commerce, and high-growth platforms.
Africala provides Voice OTP services across Africa, helping businesses improve authentication reliability through optimized voice infrastructure and real-time delivery.
