Frequently Asked Questions

Everything you need to know about DLT, delivery turnarounds, API integrations, and wallet billing.

Our dedicated OTP route achieves sub-2.8 second delivery across all Indian telecom circles. If a carrier encounters momentary congestion, automated fallbacks reroute the packet within 15 seconds.
For custom alphanumeric sender headers (e.g., GS-STORE), TRAI DLT registration is mandatory under Indian law. However, if you are testing or require instant setup with zero paperwork, our Non-DLT Gateway route is immediately active upon registration.
We connect directly via Meta's Official Cloud API. You can register your phone number, submit templates for approval, dispatch rich notifications with PDF invoices and CTA buttons, and receive incoming replies via webhooks.
Once approved, simply map your domain CNAME (e.g., sms.yourbrand.com) to our cloud servers. Your branded portal, custom logo, pricing controls, and client registration system will go live within 24 hours.
If an operator fails to deliver an SMS due to an invalid destination number or permanent carrier rejection, the deducted credits are automatically refunded to your wallet in real time.
