Free WhatsApp CRM in India: What's Actually Free, and What It Costs You
"Free WhatsApp CRM" sounds simple — but free tools come with limits, and Meta charges per conversation on the WhatsApp API. Here's what's genuinely free, what free tools usually cost you in lost leads, and what 3Sigma costs after its 7-day free trial.

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 itself is free and you're not paying Meta per conversation — and even then, free versions usually come with limits. Here's what is actually free, and where 3Sigma fits.
What is actually free — and what "free" usually costs you
Three kinds of "free" show up when you search. None of them is a full WhatsApp CRM for a sales team, and 3Sigma does not have a free plan.
Free
The WhatsApp Business App
Meta's free app for one-to-one chats: business profile, quick replies, away messages, labels and a product catalogue. It is a messaging app, not a CRM.
Free for 7 days
3Sigma's 7-day free trial
Try the product with your own leads and team. No credit card needed. After the trial you choose Premium+ or Ultimate.
Free, with limits
Free tiers of other CRMs
Some CRMs offer a limited free tier. These usually cap what you can do, such as users, leads or features, and the WhatsApp API still costs extra.
What "free" usually costs you
- Lost leads: Without a pipeline, follow-up reminders and call logs, leads sit in personal chats and phone contacts. A lead that waits days for a reply often buys from someone else.
- Limits that show up later: Free tiers commonly cap users, leads or features, so you hit the wall just when your team starts to grow.
- WhatsApp stays manual: The free WhatsApp Business App works on a few linked devices and has no lead assignment, no pipeline and no team reports.
- The Meta bill does not go away: Whatever CRM you pick, Meta's per-conversation charges apply when you use the WhatsApp Business API.
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.
Try the core mobile CRM free for 7 days
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. That is what the trial is for: test it with your own leads before you pay. 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 needs the Ultimate plan or a paid add-on
Premium+ covers the core CRM. WhatsApp API features sit on Ultimate, and a few extras are paid add-ons. 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 is part of the Ultimate plan, with the WhatsApp Business API or a Coexistence setup.
Bulk WhatsApp broadcasts
Sending campaigns to your contact list via the WhatsApp API is part of Ultimate, and Meta's per-conversation charges apply on top of your 3Sigma plan.
AI bot
The AI bot that auto-replies to leads on WhatsApp using your knowledge base is part of Ultimate and uses prepaid AI credits.
Live Tracking, Attendance and setup help
Live Tracking and Attendance are paid per-user add-ons. Assisted WhatsApp API onboarding (₹2,000 one-time), custom branding and domain (₹3,000 per year) and done-for-you CRM setup (₹10,000 one-time) are optional extras.
What 3Sigma costs after the trial: Premium+ is ₹1,200 per user per quarter or ₹2,400 per user per year. Ultimate is ₹1,800 per user per quarter or ₹3,600 per user per year. Meta's WhatsApp conversation charges are billed by Meta separately. See the pricing page for current plan details and to compare what's in each plan.
How to try a WhatsApp CRM in India without paying upfront
The most practical way to get started without upfront cost — and without being surprised by Meta's conversation charges — is to use the 7-day free trial, start with the mobile CRM and add WhatsApp when you're ready.
Download the 3Sigma app and start the 7-day free trial
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. No credit card needed.
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.
Choose your plan when the trial ends
Premium+ covers the core CRM. When your team is ready to send bulk campaigns, use approved templates or run multi-day drip sequences, choose Ultimate and set up the WhatsApp Business API with 3Sigma's help (assisted API onboarding is an optional ₹2,000 one-time add-on).
Free tools vs 3Sigma (paid)
Free tools are fine for getting started. Here is what changes when a team runs sales on WhatsApp and calls. The middle column describes typical free options in general, not one specific product.

| Meta WhatsApp conversation charges | Apply on any WhatsApp API setup | Billed by Meta separately; 3Sigma adds no per-message fee |
| What it costs | Free upfront; the cost is limits and lost leads | Premium+ ₹2,400 or Ultimate ₹3,600 per user per year (₹1,200 or ₹1,800 per user per quarter) |

FAQs — Free WhatsApp CRM India
Is there a free WhatsApp CRM for Indian businesses?
There are free tools, but they come with limits. The WhatsApp Business App is free for one-to-one chats, and some CRMs have limited free tiers. 3Sigma does not have a free plan. It has a 7-day free trial with no credit card needed, and after the trial you choose Premium+ (₹1,200 per user per quarter or ₹2,400 per user per year) or Ultimate (₹1,800 per user per quarter or ₹3,600 per user per year). Meta also charges separately per conversation when you use the WhatsApp Business API.
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 is actually free with 3Sigma?
The 7-day free trial, with no credit card needed. There is no free plan. After the trial you choose Premium+ or Ultimate. Premium+ covers unlimited leads, auto-sync from 20+ lead sources, lead form and bulk import, calling and call logs, follow-up reminders and tasks, pipelines, and dashboard and reports. Ultimate adds the WhatsApp Business API and shared team inbox, email and WhatsApp campaigns, WhatsApp sequences and advanced automations, AI WhatsApp bots (which use prepaid AI credits), orders, invoices and quotations, sales targets, iOS app access and a 4-8 hour support SLA.
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), and Meta bills that separately from your 3Sigma plan. 3Sigma adds no per-message fee. 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?
Free options exist, such as the WhatsApp Business App on its own, but it is a messaging app, not a CRM: no pipeline, no follow-up reminders and no call logs. With 3Sigma you can use the 7-day free trial for lead management, pipeline and calling without connecting the WhatsApp API at all, and Premium+ covers those without the API. Many small teams start without the API and add it later as their team grows.
What does 3Sigma cost after the trial?
Premium+ is ₹1,200 per user per quarter or ₹2,400 per user per year. Ultimate is ₹1,800 per user per quarter or ₹3,600 per user per year. Optional add-ons: Live Tracking and Attendance (per-user), assisted WhatsApp API onboarding (₹2,000 one-time), custom branding and domain (₹3,000 per year) and done-for-you CRM setup (₹10,000 one-time). Meta's conversation charges are billed by Meta separately.
