That's the right starting point, because it's where adoption is furthest along. But

A grounded look at GSMA Open Gateway and CAMARA Network APIs, what's already live in India, and what it actually means for businesses built on Bulk SMS, WhatsApp Business API, and RCS. Introduction Every few years, a new piece of telecom infrastructure shows up promising to make an entire layer of the messaging business obsolete. Sometimes that fear is justified. Often it isn't, or it's justified only for a narrow slice of the business. CAMARA — the open-source project standa

For most of the last decade, "consent" in Indian SMS marketing meant one thing: a consent template registered on the DLT portal, a customer who tapped a link or replied YES, and a record sitting somewhere in an operator's database that you could point to if anyone ever asked.

Most businesses set up OTP delivery once and never think about it again — until it breaks, gets blocked by a carrier, fails a compliance audit, or costs them thousands of customers who abandoned a checkout because a code nev

Every time a user logs into a fintech app, confirms a payment, or registers on an e-commerce platform in India, an OTP (One-Time Password) is the final gatekeeper.
