Case study: OTP delivery for an online store
Problem
Checkout OTPs arrived late or failed on some networks, so customers abandoned carts. The previous route was not a dedicated Sri Lankan operator path.
What changed
The store kept generating OTPs in its own app and switched SEND_SINGLE to VeloBotix with a registered Sender ID. WooCommerce order SMS stayed on the same account as transactional traffic.
Result (customer-reported)
The merchant reported OTP delivery moving from about 89% to about 99% after the switch. That figure is their measurement, not a lab benchmark. Your results depend on lists, templates and networks.
