In Kolkata, a message in Bengali is often the one that gets read. MetaReach lets businesses send promotional, service and OTP SMS in Bengali or English from one account, from ₹0.12 per SMS + GST at volume, with free DLT setup support.
By Ravi Kant - Founder & CEO, MetaReach Marketing
Bulk SMS in Kolkata costs ₹0.40 per SMS at 5,000 messages, falling to ₹0.12 from 1 lakh, plus GST, the same as the rest of India. Bengali SMS uses the same rates, but one segment holds 70 characters, not 160. You need DLT registration, and MetaReach supports it free.
From Burrabazar wholesalers to Salt Lake IT firms and EM Bypass hospitals, businesses can use the same platform for festival offers and time-critical alerts. MetaReach serves 500+ businesses across India, including clients in Kolkata, in business since 2016 (10+ years), and has delivered 500 crore+ SMS. Messages reach Jio, Airtel, Vi and BSNL numbers, and most OTPs are delivered within 5 seconds on priority routes. See our bulk SMS service for the full platform.
Pricing is the same in Kolkata as everywhere else in India. You pay by volume, with no setup fee and no monthly minimum. See the full bulk SMS price guide.
| Monthly volume | Price per SMS (+ GST) | Example |
|---|---|---|
| 5,000 – 9,999 | ₹0.40 | 5,000 SMS = ₹2,000 |
| 10,000 – 19,999 | ₹0.30 | 10,000 SMS = ₹3,000 |
| 20,000 – 49,999 | ₹0.20 | 25,000 SMS = ₹5,000 |
| 50,000 – 99,999 | ₹0.15 | 50,000 SMS = ₹7,500 |
| 1,00,000 – 5,00,000 | ₹0.12 | 1,00,000 SMS = ₹12,000 |
| Below 5,000 or above 5,00,000 | Custom quote | Talk to sales |
Prices exclude 18% GST. The same rate applies to promotional, service and OTP SMS. One SMS segment is 160 English characters, or 70 characters in Bengali, Hindi and other Unicode languages. Longer messages are billed as multiple segments.
MetaReach supports your DLT entity, header and template set-up free. The operator's one-time entity registration fee, commonly ₹5,900 including GST, is paid directly on the DLT portal.
Bengali messages use Unicode, so one SMS holds 70 characters instead of 160. Longer messages are split into segments of about 67 characters, so a 120-character Bengali offer is billed as two SMS.
| When | Occasion | What businesses send |
|---|---|---|
| Mid-April | Poila Baisakh (Bengali New Year) | New-year offers, halkhata invitations to trade customers |
| Sept – Oct | Durga Puja | Festive offers, pandal-hopping deals, delivery updates |
| Oct – Nov | Kali Puja, Diwali, Bhai Phonta | Sweets, gifts and jewellery offers |
| Nov – Feb | Wedding season | Jewellery, clothing and caterer offers |
| Dec – Jan | Christmas, Park Street season, New Year | Restaurant and event promotions |
Festival dates move each year. Register your offer templates two to three weeks early, because operator approval can take a few days in peak season.

Transactional templates on DLT are reserved for banks; most other businesses register alerts under service categories.
India's commercial SMS rules changed several times between 2024 and 2026. When approved messages suddenly stop delivering, one of the changes below is often the cause. MetaReach checks each of them during onboarding at no extra charge.
These rules are national. A business in Kolkata follows the same DLT process as one in Delhi or Mumbai, and we complete it with you over a call and screen-share. See DLT registration support.
Three real campaigns run through MetaReach's bulk SMS platform by Kolkata businesses.
A boutique and saree store in Gariahat ran its Durga Puja offer campaign through MetaReach — 50,000 messages sent inside two hours, with the Bengali SMS option driving noticeably stronger response from local customers.
A diagnostic centre in Salt Lake switched to Bengali appointment reminder SMS and saw no-show rates drop by more than a third — the Bengali message felt more personal to patients than the English original.
A New Town project launch campaign sent 8,000 messages the same day, generating 180 enquiry calls — with a parallel OBD voice campaign adding another 60 callbacks.
From businesses running real campaigns across Kolkata.
"MetaReach handled our Durga Puja SMS campaign perfectly — 50,000 messages in two hours, with delivery reports for every one. The Bengali SMS option was a big hit with our local customers. We'll definitely use it again for Kali Puja."
"Our patients kept missing appointments — a common problem. After switching to MetaReach's Bengali appointment reminder SMS, no-show rates dropped by 35%. The Bengali message feels more personal to our patients than English."
"MetaReach ran our project launch SMS campaign for our New Town project — 8,000 messages, same day. We got 180 enquiry calls the same evening, and the OBD campaign they ran alongside added another 60 callbacks."

What Kolkata businesses ask before they decide.
From ₹0.40 per SMS at 5,000 messages down to ₹0.12 from 1 lakh, plus GST, for promotional, service and OTP messages alike. Volumes below 5,000 or above 5 lakh get a custom quote.
Yes, at the same per-SMS rate. A Bengali SMS fits 70 characters per segment, so a longer message counts as two or more SMS. The template must be registered in Bengali on DLT.
Register offer templates two to three weeks before Mahalaya. Operators get busy close to the festival, and approvals can take longer.
Yes. Businesses sending commercial SMS anywhere in India must register their entity, header and templates on a DLT platform. MetaReach supports this free; the operator portal fee, commonly ₹5,900 including GST, is paid separately. Timing depends on your documents and operator approvals.
Messages reach Jio, Airtel, Vi and BSNL numbers. Actual delivery depends on the number, network and message category, so check your delivery reports.
