For businesses in DR Congo, One-Time Passwords (OTPs) are mission-critical. A delayed verification code means a failed registration or an abandoned transaction. DR Congo is one of Africa's largest markets with over 50 million subscribers across four operators.

Why OTP Delivery Speed Matters

OTP codes are time-sensitive — usually valid for 3–5 minutes. Poor delivery leads to abandoned sign-ups, failed logins and more "code not received" support tickets. eSMS Africa's direct routes deliver OTPs in seconds with 99%+ success rates.
