PING4SMS delivers OTP SMS in under 3 seconds on average across all major Indian networks — Jio, Airtel, Vi, and BSNL. We use dedicated priority routing and direct telecom operator connections through our AWS-powered infrastructure.

Priority routing means your OTP SMS goes through a dedicated high-speed channel — separate from bulk promotional traffic. This ensures your login OTPs, payment OTPs, and registration verifications reach customers instantly, even during peak traffic hours.

DLR (Delivery Receipt) is a real-time status update confirming whether an OTP was delivered to the customer's phone. PING4SMS provides DLR via dashboard and webhook callbacks to your server — so your app knows instantly if an OTP was delivered or failed.
