Meta charges per conversation on the WhatsApp Business API
When you connect your CRM to WhatsApp via the official WhatsApp Business API — which is required for bulk campaigns, shared team inbox and approved templates — Meta (Facebook) charges a fee per conversation. These charges are separate from whatever the CRM platform charges. Indian businesses sending thousands of messages per month often find this is a significant cost.
This is not specific to 3Sigma — it applies to AiSensy, Wati, Interakt and every platform that uses the official WhatsApp Business API. It's a Meta charge, not a platform charge, and it applies because WhatsApp is a paid messaging channel at scale.
What this means for Indian SMBs: "free WhatsApp CRM" is only genuinely free if the CRM plan itself is free and you're not paying Meta per conversation. Here's how 3Sigma threads that needle.
Two ways to connect WhatsApp in 3Sigma
Not all WhatsApp connections are the same. 3Sigma offers two different WhatsApp integrations with different cost and capability profiles.
WhatsApp Coexistence
Use your existing WhatsApp Business number
- Connect your existing WhatsApp Business App number — no new number needed
- Contacts and chat history sync into 3Sigma on setup
- Keep using the WhatsApp app on your phone at the same time
- Team can see and reply from the shared inbox in 3Sigma
Best for: teams that already have a WhatsApp Business number and want to bring it into a CRM without migrating to a new number.
WhatsApp Business API (WABA)
Official API — full broadcast and template access
- Verified business profile, green-tick eligible
- Approved message templates for campaigns
- Bulk broadcasts to large opted-in lists
- Shared team inbox with assignment and filters
- Meta charges per conversation (separate from 3Sigma fee)
Best for: teams sending bulk campaigns, needing a green-tick number, or wanting a dedicated CRM inbox separate from a personal WhatsApp.
3Sigma helps with API setup for both options. See the WhatsApp Business integration page for more detail.
Start free with the core mobile CRM
Amit Kaul from Chandigarh runs a team of 4 selling insurance. He downloaded 3Sigma and started managing his leads, making calls and setting follow-ups the same day — before ever connecting WhatsApp API. The SIM-based dialer, the pipeline, the follow-ups — the core CRM, on his phone, from day one. Check the pricing page for exact plan inclusions.
Lead management
Capture, organize and track leads — custom fields, statuses, labels, filters, search, bulk actions and a per-lead timeline.
SIM-based auto-dialer
Dial your lead list back-to-back on your own SIM. Every call auto-logged — duration, outcome, notes, no manual entry.
Follow-up management
Reminders, tasks and follow-up presets so no lead goes cold — set a follow-up from the after-call popup in one tap.
Mobile-first pipeline
Kanban or list view, drag deals across stages, see deal value — the full pipeline on Android and iOS.
The 3Sigma mobile CRM is available on Android (full feature set) and iOS (Ultimate plan).
What typically needs a paid plan
WhatsApp API features and advanced team tools generally sit on higher plans. The exact split is on the pricing page — here's the general picture:
WhatsApp shared team inbox
The shared inbox where your whole team sees and replies to WhatsApp messages requires the WhatsApp Business API or Coexistence setup.
Bulk WhatsApp broadcasts
Sending campaigns to your contact list via the WhatsApp API also involves Meta's per-conversation charges, on top of your 3Sigma plan.
AI bot (Gemini / OpenAI)
The AI bot that auto-replies to leads on WhatsApp using your knowledge base is an advanced feature.
Advanced team features
Multi-user assignment, role-based permissions, multi-branch, caller leaderboard, advanced reporting and live tracking are advanced team capabilities.
Pricing note: Plans start at affordable rates per user per quarter or per year. See the pricing page for current plan details and to compare what's in each tier.
How to start with a free WhatsApp CRM in India
The most practical way to get started without upfront cost — and without being surprised by Meta's conversation charges — is to start with the mobile CRM and add WhatsApp when you're ready.
Download the 3Sigma app and start the free plan
Set up your lead pipeline, import existing leads (Excel/CSV or Google Contacts), and start calling. The auto-dialer, follow-ups and pipeline are available from day one.
Connect WhatsApp Coexistence (your existing number)
If you already have a WhatsApp Business App number, connect it via Coexistence. Your chat history and contacts sync in. Your team can see and reply from the shared inbox. This is a good first step before committing to full API.
Upgrade to WhatsApp API when you need bulk campaigns
When your team is ready to send bulk campaigns, use approved templates or run multi-day drip sequences — that's when you upgrade to a paid plan and set up the WhatsApp Business API with 3Sigma's help.
Core CRM vs advanced features
The core mobile CRM is where most teams start. WhatsApp API and advanced team features sit on higher plans — see the pricing page for exactly what each plan includes.

FAQs — Free WhatsApp CRM India
Is there a free WhatsApp CRM for Indian businesses?
Yes — you can start with 3Sigma's core mobile CRM for free. It lets you manage leads, make calls, set follow-ups and use the pipeline. WhatsApp API features (shared inbox, bulk broadcasts) and advanced team tools depend on your plan, and Meta also charges separately per conversation when you use the WhatsApp Business API. See the pricing page for exact plan inclusions.
Why isn't WhatsApp Business API free?
Meta, which owns WhatsApp, charges a per-conversation fee for the WhatsApp Business API. Charges vary by conversation type (service, marketing, utility, authentication) and by country. These are Meta charges independent of whatever CRM or platform you use. Indian businesses were often surprised by these costs when they first moved to API-based WhatsApp CRMs.
What is WhatsApp Coexistence and how is it different from the WhatsApp API?
WhatsApp Coexistence (available in 3Sigma via Meta's Embedded Signup) lets you connect your existing WhatsApp Business App number to the CRM. You keep using the WhatsApp app on your phone at the same time, and your contacts and chat history sync into 3Sigma. The WhatsApp Business API is a separate integration that gives you a dedicated number, approved templates and bulk broadcasting capability. Coexistence is how most businesses start, because it requires no new number and no WhatsApp app migration.
What does the core mobile CRM include?
The core mobile CRM you can start with for free covers the essentials — lead management, pipeline, calling, follow-up management, notes and tasks. WhatsApp API features and advanced team features depend on your plan. See the pricing page for exact, current plan details.
Do I need to pay Meta to use 3Sigma's WhatsApp features?
If you connect via the WhatsApp Business API, Meta charges per conversation (the rate depends on conversation type). If you connect via WhatsApp Coexistence (your existing WhatsApp Business App number), that's a different integration. Check the pricing page and ask the 3Sigma team about the right option for your setup.
Can I use a WhatsApp CRM for free without the WhatsApp API?
Yes. You can start with 3Sigma's core mobile CRM for lead management, pipeline and calling without connecting the WhatsApp API at all. Many small teams start with just the mobile CRM and add WhatsApp integration later as their team grows. Check the pricing page for what each plan includes.
