An App for Field Sales Teams That Sell by Phone and WhatsApp

By · Chief Executive Officer, Wappblaster

In short: For field reps who sell by phone and WhatsApp, the highest-value tooling is not GPS tracking: it is assigned leads with history, follow-up reminders that ring, WhatsApp that sends itself after calls, and records that save offline. RMDialer does exactly that scope, and does not do beat planning or live location tracking.

A rep spends the day visiting dealers, calling ahead, quoting on WhatsApp, and promising to “send the details tonight”. By the third visit, the morning’s promises are gone. The problem is not discipline. It is that the record of each conversation lives in the rep’s head, and heads overflow.

Most software marketed to “field sales” attacks a different problem: live GPS tracking, geo-fenced attendance, beat planning, route optimisation. If you need to verify where reps physically are, that is a real category - Field Force Automation - and you should buy it. RMDialer is a calling and follow-up app, not a location tracker, and this post will not pretend otherwise.

What RMDialer does for a field team is narrower and, for phone-and-WhatsApp selling, usually more valuable: it makes each rep’s phone remember everything the rep cannot.

What actually breaks for a travelling rep

  • The follow-up promised at 11 am is forgotten by 4 pm. In RMDialer, that promise is saved in two taps when the call ends and rings later like an alarm, with the whole history attached.
  • “Send me the price list” gets sent at midnight, or never. Auto WhatsApp sends the details the moment the call ends, while the dealer is still looking at their phone.
  • The office cannot see what happened on the road. Every call a rep makes or receives is logged with its status and remark under their name, so the owner sees calls, outcomes and due follow-ups per rep, without anyone filing a day report.
  • Patchy network eats data entry. Statuses and remarks save on the phone offline and sync when signal returns, so a day in a low-network industrial area does not leave holes.
  • A new rep inherits nothing. With assigned leads, a transferred lead carries its entire history - every call, remark and promise - so the customer never repeats themselves.

One honest GPS note: a lead record can store a GPS location field, useful for remembering where a dealer’s shop actually is. That is a field on a record, not live tracking of your rep, and we would rather say so plainly than let you buy the wrong product.

The realistic tool split for field teams

  • You need proof of presence, routes and attendance → buy a Field Force Automation tool (Happisales, TrackOlap and similar are the category).
  • Your reps sell by calls and WhatsApp, and the leak is memory and follow-up → a dialer that is also the CRM fixes the leak at its source: the phone itself.
  • You have both problems → the two products coexist without conflict; one owns location, the other owns the customer record.

At ₹159/user/month on yearly (every feature included), the second tool costs less than the fuel a rep burns in a day, and it is the one that stops sold-but-never-followed-up from being your most expensive lead status.

Questions

Questions people ask about this

What app should a field sales team use for follow-ups?

For reps who sell by phone and WhatsApp, the highest-value tooling is not GPS tracking. It is assigned leads with history, follow-up reminders that ring, WhatsApp that sends itself after calls, and records that save offline when the network is poor.

Is GPS tracking useful for a field sales team?

It answers where someone was, which is rarely the question that decides revenue. What was said, what was promised and what is due next matters more, and those come from the call record rather than the map.

How to send a WhatsApp message automatically after a call?

Use a dialer with auto WhatsApp: set a message once per call type (missed, incoming, outgoing) and per lead status, and the app sends it the moment the call ends, personalised with the customer's name. From the user's own number it opens WhatsApp with the message ready; through the WhatsApp Business API it sends with zero taps.

Do I need the WhatsApp Business API to send automatic messages?

Not for one-to-one follow-ups: a dialer can open WhatsApp on your own number with the message prepared after each call. You need the official API for fully hands-free sending, bulk campaigns to hundreds of numbers with delivered and read reports, and message templates. RMDialer works both ways and connects to the API from Meta or any provider.

How to send bulk WhatsApp messages without getting banned?

Send to people who know you and have opted in, personalise with the name, keep to a few hundred a day from a normal number with gaps between messages, and stop sending to anyone who does not reply or asks you to stop. For larger volumes use the official WhatsApp Business API with approved templates, which cannot be banned for volume and gives delivery reports.

Does bulk WhatsApp from my own number work without an API?

Yes, one message at a time from your phone: the app prepares each message with the name filled in and hands it to WhatsApp, and you tap send. It is safe for lists of a few hundred known contacts. For thousands of numbers, or for reports of delivered, read and replied, the WhatsApp Business API route is the right one.

How do I remind clients about renewals automatically?

Record each paying client once with the product, package, amount paid, amount due and expiry date. The app then rings the right person before expiry (for example 30, 7 and 1 days before) and can send a WhatsApp reminder automatically at each step, so renewals stop depending on a diary.

What is a telecalling CRM?

A telecalling CRM is customer software built around phone calls: the lead list, the dialer, the call outcome and the follow-up live in one place. The mobile kind, such as RMDialer, replaces the Android phone app on each rep's handset so every call automatically becomes a record with a status, a remark and the next follow-up, and the manager sees the whole team on a web dashboard.

What is the difference between telecalling software and a CRM?

Telecalling software is built to make and track calls (dialing lists, call logs, per-caller reports). A CRM is built to hold customer records and pipeline stages. Most Indian sales teams need both at once, which is why a telecalling CRM combines them: the call itself creates and updates the customer record, so nobody types into a separate system after the call.

What is a CRM dialer?

A CRM dialer is a single app where the dialer and the customer record are the same thing: the call screen shows the lead, and ending the call updates it. It differs from a CRM with "dialer integration", which is two products joined by a sync. RMDialer is a CRM dialer for Android that runs on the user's own SIM.

How long does it take to set up a telecalling app for a team?

About an hour for a small team. Each person installs the app from the Play Store, signs in with the team account and sets it as the default phone app. The owner adds users on the Web CRM, imports the first lead list from Excel and assigns it. Most teams make their first auto-dialled calls the same day.

Do I need a virtual number to run a calling team?

No. A virtual number is only needed when calls must be routed through a cloud platform, for example for an inbound IVR. An outbound sales team can run entirely on business SIMs in the reps' phones, with the app logging every call and the owner reading the reports. Customers also answer known mobile numbers more readily than unfamiliar virtual ones.

How do I assign leads to telecallers automatically?

Import or connect the lead source once, then turn on round-robin assignment: each new lead goes to the next active employee in rotation, their phone pings, and the lead appears in their assigned queue with the auto dialer ready. Managers can reassign or transfer a lead any time and the transfer history stays on the record.

Why do telecallers stop using the CRM?

Because a separate CRM means typing after every call, and on a busy day the typing is the first thing dropped. The fix is a CRM that lives inside the dialer: the call creates the record, the outcome is two taps on the after-call screen, and the follow-up is set in the same motion. When updating the CRM costs nothing extra, it stays updated.

Can a telecalling CRM work for a team working from home?

Yes. Each rep installs the app on their own Android phone with the business SIM, and every call they make from home is logged and synced exactly as it would be in the office. The owner sees calls, talk time and outcomes per person on the Web CRM, and leads are assigned remotely, so a distributed team runs like a single desk.

  • “Telecaller app for Android that my staff actually use. Enquiry list is assigned to each telecaller, the auto dialer calls it from their own SIM, and test ride bookings come to me live. Punjabi interface for the girls at the desk. Price is honest, everything included, no per-user surprises.”
    Harpreet Singh Owner · Two-wheeler showroom Ludhiana
  • “We needed an auto dialer app that works on our own MTN and Airtel lines, not a call centre subscription in dollars. RMDialer runs on the phones my agents already have, dials the enquiry list, and the WhatsApp follow-up goes out after every call. Works even when the network drops and syncs later.”
    Grace Okafor Managing director · Travel agency Lagos, Nigeria
  • “We looked for telecalling software for a nine-person loan team and every quote came with cloud seats and per-minute bills. RMDialer telecalling software runs on the callers' own Jio SIMs: the lead list dials itself, the remark goes on the number, and I get dials, connects and talk time per caller every evening. Cost is one flat price per user.”
    Kavita Iyer Operations head · Loan DSA Chennai
  • “Earlier I was dialling 80 to 100 portal leads a day by hand from Excel. With RMDialer auto dialer app I import the sheet, press start and it calls one by one from my own Jio SIM. Between calls I mark Interested or Site visit in two taps and the follow-up rings me on time. Closed 3 flats last month from leads I would have forgotten.”
    Rakesh Choudhary Real estate consultant · Property advisory Jaipur
  • “We tried two telecalling CRM software before this and my counsellors stopped filling them within a week. RMDialer is the phone app itself, so every admission enquiry gets logged whether they like it or not. The auto WhatsApp after call sends the fee structure by itself. I see all 4 counsellors' calls on the web CRM every evening.”
    Priya Nair Owner · Coaching institute Kochi
