WHY THIS CAPABILITY MATTERS
Engineered for Measurable Business Impact.
When time-sensitive alerts, OTPs, appointment reminders, or seasonal offers must reach thousands of customers immediately, carrier-grade SMS and RCS deliver unmatched reach.
One Roof Ads provides dual messaging power: universal Bulk SMS that reaches every mobile phone even without internet connectivity, and Rich Communication Services (RCS) that upgrade native messaging inboxes with verified sender logos, interactive product carousels, one-tap action buttons, and read receipts.
All Bulk SMS and RCS services operate in strict compliance with TRAI DLT regulations (in India), DND filtering rules, and carrier guidelines. RCS rich-media features depend on recipient device and carrier RCS capability, with standard SMS fallback options.
