What is RCS Messaging? The Smart Alteration Service of Normal Bulk SMS
You've been using normal bulk SMS for years — 160 characters, no images, no buttons, no branding. RCS is the alteration service of normal bulk SMS that you've been waiting for. Think of it as WhatsApp Business API's powerful alternative that lives directly inside your customer's Android messaging inbox. No app download needed. No opt-in friction. Just pure, rich communication.
With RCS business messaging in Kolkata, you can send:
- 📸 High-resolution images — product photos, banners, offers
- 🎥 Videos — product demos, brand stories, tutorials
- 📄 PDFs — catalogs, menus, brochures, price lists
- 📝 Long text (English/Unicode) — no 160-character limit, perfect for Bengali and English
- 🔘 Interactive buttons — "Call Now", "Visit Us", "Shop Now", "Track Order"
- 🎠 Carousels — swipeable product cards like WhatsApp catalogs
- ✅ Read receipts & typing indicators — know exactly when your message is seen
This is exactly the same feature set as the WhatsApp Business API alteration — but delivered to the native Android inbox as a template, not through a separate app. For businesses in Kolkata and West Bengal, this means unmatched visibility and engagement.
