How to Use WhatsApp Business Calling on the Wati Mobile App

Most sales reps will tell you the same thing. Their best leads call back at the worst times. 

Between meetings, during lunch, or on the way to a client site. 

The WhatsApp Business call comes in, nobody picks up, and a perfectly warm conversation goes cold. Getting WhatsApp Calling on Business on the phone your sales rep already has in their pocket solves this entirely.

Wati’s mobile app now supports WhatsApp Business Calling on iOS and Android. Your sales rep can make and receive calls, see the full chat thread before picking up, manage call permissions, and follow up on missed calls from wherever they are. 

Everything syncs between mobile and web in real time, so your team inbox stays clean no matter who picks up or where.

If you have already enabled WhatsApp Business Calling on Wati and want to extend it to your team’s phones, this guide has everything you need.

Why are the Best Sales Teams Moving WhatsApp Business Calling to Mobile?

For sales teams doing field visits, founders handling high-value conversations, and support leads covering extended hours, the desk is rarely where the important calls happen. 

Having WhatsApp Business Calling only on the web app means coverage depends entirely on someone being in front of a screen, which, for most customer-facing teams its difficult to sit in front of the screen for a long time

WhatsApp Business Calling on mobile keeps up with that reality in three ways.

• Full chat context on every call: When a call comes in, the sales rep sees the complete chat thread on the same screen. Every prior message, every context clue, everything they need before saying a single word.

• Web and mobile stay in sync continuously: A call taken on mobile shows up in the web dashboard instantly. Permissions granted on the web are visible on mobile. Missed calls flagged on mobile get picked up by the team on the web. The two surfaces behave like one system.
• Call availability travels with the agent: Agents can toggle availability, check which customers have active call permission, and manage their call queue from the mobile app. No laptop needed, no dashboard to check later.

For teams where agents are rarely at a desk, that continuity is what makes WhatsApp Business Calling genuinely operational rather than just occasionally useful.

What Do You Need Before Setting Up WhatsApp Business Calling on Mobile?

Good news: the checklist is short.

1. Wati mobile app version 3.43.1 or later

This is the minimum version that supports WhatsApp Business Calling on iOS and Android. Check your current version in the App Store or Google Play before anything else. If you are behind, a quick update is all it takes.

2. WhatsApp Business Calling is enabled on your WhatsApp Business API web account

Mobile calling runs off your existing web setup. If calling is already live on your Wati account, you are ready to go. If you have not set it up yet, start with the WhatsApp Business Calling setup guide and come back here once that is done. 

The whole web configuration is easy and takes minimal time. 

Once both boxes are checked, setting up your team’s phones takes under two minutes per device. 

How Do You Set Up WhatsApp Business Calling on iOS and Android?

Two minutes per device. Here is exactly what you need to do.

On iOS:

1. Open the Wati mobile app
2. Allow notification permissions when prompted
3. Select Always Allow

That single permission setting is what determines whether an incoming WhatsApp Business Call appears on your agent’s screen or rings silently into nothing. 

Most missed call issues on iOS trace back to this one step being skipped.

On Android:

1. Open the Wati mobile app
2. Tap Calls in the bottom navigation menu
3. Tap Open Settings when prompted

4. Enable full-screen notification permissions

Once done, incoming WhatsApp Business Calls appear as a full-screen takeover on the device, just like a standard phone call. 

Agents who already use WhatsApp personally will find it immediately familiar.

What Can Your Sales Rep Actually Do From the Mobile Call Tab?

Setup is done. Here is what your team can do from the moment they open the Calls tab on their phone.

1. Follow up on missed calls immediately

Tap Missed in the call log, and every unanswered inbound call is right there. 

Your agent can call back, send a message, or check the full chat thread without switching to another app or waiting to get back to a desktop. 

For sales teams, this is the difference between recovering a lead and losing one.

2. Call customers who have already opted in

The Request Accepted filter surfaces every contact with active call permission.

For a sales rep between meetings, this is the priority list to work through. No manual permission checking, no risk of calling someone who has not opted in, no compliance headaches.

3. Send permission requests on the go

If a contact has not yet granted permission, the sales rep can send the consent template directly from the mobile app. 

When the customer accepts, they appear in the Request Accepted view automatically, ready to call. 

The whole flow happens without touching the web app once.

4. See the full chat thread before picking up

When an inbound call comes in, the agent sees the complete conversation history on the same screen. 

Everything the customer has said, asked, or been told is right there before the agent says a single word.

WhatsApp Business Calling Not Working on Mobile? Here Is How to Fix It

Most mobile calling issues trace back to one of a handful of causes. Here is a quick reference to identify and fix the most common ones.

Which Teams Get the Most Out of WhatsApp Business Calling on Mobile?

Mobile calling on Wati works for any team. However, three types of teams feel the difference most immediately. 

1. Field Sales Teams in Real Estate, Lending, and Edtech

These are agents who spend most of their day away from a desk. Property consultants at site visits, loan officers at client offices, and edtech counselors between campus visits. For these teams, a lead that calls in during the day used to mean a missed opportunity. 

With WhatsApp Business Calling on mobile, the agent picks up with full chat context already on screen, handles the conversation on the spot, and the call logs automatically in the team inbox.

2. Teams Trying to Extend Coverage Without Adding Headcount

Praja, one of India’s pioneering hyperlocal social and news platforms with over 2+ million downloads, moved from agents dialing on personal phones with zero visibility to a structured WhatsApp Business Calling operation on Wati. 

For the first time, the team could track call-level conversion metrics and measure performance across agents on the go. WhatsApp now drives 20,000 of its 100,000 daily active users back to the app. Read the full Praja case study. 

3. Founders and Team Leads Handling High-Value Conversations

In many growing businesses, the person handling the most important calls is the founder or a senior lead. They are almost never sitting at a desktop when those calls come in. 

Mobile calling means the verified business name still appears on the customer’s screen, every call still logs to the shared inbox, and the customer’s experience doesn’t change.
