The main reason why SMS receiving is slow, because of using our public promotional SenderID. Use our SenderID to test SMS delivery and integration. Delivery speed is slow intentionally.
Each user must register/buy their own Private SenderID to ensure faster delivery and avoid delays especially for OTP messages and Virgin numbers.
Using our public promotional SenderID in production environment has many down sides:
1. Promotional senderid delay 120 seconds or more
2. NO delivery to Virgin numbers
3. NO delivery to blocked numbers (DND list)
