Short answer
A SIM-based calling CRM is software that lets telecallers call through their lead lists from the SIM cards in their own mobile phones, with each lead's details on screen and the result of every call saved to that lead. RMDialer works this way on Android, ringing one number at a time and holding the next ring until the outcome and callback date are in. In India a seat is ₹159 a month on yearly billing, or $29 per user per year, or $12 per user for 3 months, outside India.
Key takeaways
What changes for a telecalling team the week its calls start from the lead list on the phone instead of a keypad and a spreadsheet.
Press Start once and each number rings in turn, so a telecaller stops copying digits from a sheet into the keypad and starts talking sooner.
The next number waits until the caller picks what happened, which is why the list at 6 pm still says who is interested and who never answered.
Enquiries are rung from a normal mobile on the caller’s SIM, not from an unknown landline series that many people now refuse to answer.
New leads from a sheet or a web form are shared out to the callers in turn, so an enquiry gets its first call while the person still remembers filling the form.
The calling happens on the phone in the caller’s hand, which suits small offices, work from home and callers who move between desks.
Calls made, calls connected and talk time per telecaller are counted as they happen, so the morning target and the evening total use the same numbers.
From the first list in the morning to the total in the evening, the steps a telecaller goes through and the ones the CRM takes off their hands.
9:30
Filter the leads that need a call: new enquiries, follow-ups due today, or everyone left at "call later" last week.
9:40
Choose the SIM and the pause between calls, press Start, and the first enquiry rings with its source and remark on screen.
9:41
When the call ends, pick the outcome and the next date. Only then does the following number ring, after the pause you set.
11:00
Leads that did not pick up return for another ring later in the session, up to three tries, without the caller hunting for them.
2:30
Callbacks promised for the afternoon go off on time, with the last remark, so the caller opens with what was agreed.
6:00
Calls, connected calls and talk time are already counted for the day, and the leader sees them without asking for a report.
The pace of that session, and why the phone never rings two leads at once, is set out on the SIM based power dialer page. What each call writes into the lead once the conversation is over is the subject of the SIM-based call management CRM.
A calling CRM is only as fast as the moment a new lead reaches someone who can call it. Leads from a sheet or a form are spread across the team as they arrive.
Connect the sheet your ad forms fill, choose round robin or a chosen group of callers, and each new row becomes a lead in somebody's queue within minutes, tagged with its product and source. The first call goes out while the enquiry is still warm, which matters more than any script. How the sharing rules work in detail, including what happens when a caller is on leave, is covered on lead distribution CRM.
Every calling setup can reach a customer. They differ in what the telecaller has to do before each call, and in what the customer sees ringing.
| For each call | Desk phone and a CRM tab | Cloud dialer in the browser | Mobile and a printed list | SIM-based calling CRM |
|---|---|---|---|---|
| Where the number is dialled | Typed into the desk phone | Clicked in the browser, on a headset | Typed into the mobile | Rung by the CRM on the mobile |
| Work to start one call | Read, type, check the digits | One click, if the browser behaves | Find the row, type ten digits | None: the next lead rings itself |
| What the lead sees ringing | An office landline | A rented virtual number | The caller’s mobile number | The caller’s mobile number |
| When the outcome is written | Later, in the tab, if at all | In the console after the call | In pen, if the caller bothers | Before the next call can ring |
| Calling where the internet is weak | Fine for the call, the tab struggles | Calls break up or drop | Fine | Fine: calls use the voice network |
| What a new caller needs on day one | A desk, a phone and a login | A laptop, a headset and a line | A phone and the sheet | An Android phone and a login |

Real businesses, real numbers: how owners and sales teams across India and 12+ countries use RMDialer every day.
“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.”
“Forty counsellors, all on RMDialer as their telecaller app. Assigned queues, sessions from their own SIMs, and a live team dashboard with calls, connected and talk time per counsellor. The employee-wise call logs report replaced two Excel sheets and one full-time MIS person. Rollout took a week.”
“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.”
“Telecaller software that my counsellors actually open, because it is the phone app itself. Demo bookings from the website land in the queue, get dialled the same hour, and the WhatsApp with the course link goes out after each call. Four stars: the Excel import wanted the number column named exactly, so my first upload took two tries.”
“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.”
“Team of 9 salesmen on their own SIMs, no VoIP, no per-minute bills. RMDialer telecalling CRM shows me who called which customer, talk time and the remark, employee wise. Arabic interface for two of my staff was a bonus. Support on WhatsApp replied within minutes.”

A tea cafe brand in Indore selling outlet and kiosk franchises across Madhya Pradesh, with three telecallers and one franchise manager.
The brand runs Meta lead forms for would-be franchise owners: a shopkeeper in Ujjain, a retired bank officer in Bhopal, a student family wanting a kiosk near a college. The forms fed a Google Sheet, and three telecallers split the rows by hand each morning, rang them from the office landline and noted results in a column that grew longer than anyone read. Many investors never picked up a landline number they did not know.
Now the sheet is connected, and new rows are shared out to the three callers in turn as they arrive. Each caller starts the session on their own business SIM, and every enquiry rings from a mobile number the investor can save. After a call the outcome and the next date go in before the next number rings: brochure sent, site visit Saturday, royalty question for the manager. A WhatsApp message with the franchise brochure goes out after answered calls on its own.
The franchise manager reads the day's calls and the site visits booked on the office computer, and steps in only on the leads marked for him. Enquiries that came in overnight are rung before eleven the next morning, and the ones that never answered come back for another try in the afternoon instead of being forgotten in the sheet.
Calling from mobile SIMs suits most teams that call their own enquiries. Four kinds of calling are better served by something else.
If you are still comparing products rather than setups, the list of SIM-based calling CRM options sets them side by side. Calling from a desk computer is possible too: the click to call Chrome extension rings a number clicked in the browser from your phone. For the incoming side of the same phone, the ringing screen and the call history a shop or salesperson uses all day, see the SIM-based calling app.
Written with a hyphen or without it, SIM-based calling CRM and SIM based calling CRM are one search, and "SIM calling CRM" is the short form some people type. Calling it software points at the team leader's browser, where lists are shared and totals are read; calling it an app points at the telecaller's phone, where the list actually rings. Both are part of the same tool.
You will also see it called sim based calling crm, sim based calling crm software, sim based calling crm app and sim calling crm. They describe the same thing, so whichever phrase brought you here, this is the page for it.
Filter leads by status and how long ago they were last contacted, then start auto-dial on exactly that group.
Each call rings from your SIM with the enquiry, its stage and the last remark visible while it connects.
Pick what happened and when to ring again; the reminder is set and the list moves to the next number.
Telecallers working enquiry lists are best served by RMDialer as their SIM-based calling CRM. It rings the list from each caller's own SIM, puts the lead on screen during the ring, and will not move on until the result and the next callback are saved. Pricing is ₹159 per seat monthly, billed yearly in India ($29 per user per year, or $12 per user for 3 months, outside India), for Android phones plus a browser view for the team leader.
Yes. RMDialer is a SIM-based calling CRM: telecallers call their assigned leads one after another from their own mobile SIMs, the lead’s details show during each call, and every outcome is saved to that lead. Team leaders follow the calling in the same app or in a browser, and no virtual number or headset line is involved.
A dialer app places calls. A calling CRM places calls from a list of leads and keeps what came of each one: the stage, the remark, the next date and who called. A dialer leaves you with a call history; a calling CRM leaves you with a pipeline you can work tomorrow.
Yes. Pick a list, a status or the follow-ups due today and press Start, and the numbers ring one after another on your SIM. You only talk and save the result. The list can come from an Excel or CSV file, a connected Google Sheet or leads assigned by your manager.
You set it, and an admin can lock it for the whole team. The gap gives time to save the outcome before the next number rings. A lead can also be counted as called only after the call lasts 5, 10 or 30 seconds, so a cut call does not tick it off.
Yes. Every call goes out on the SIM you choose, so the lead sees your usual mobile number, the one they can save and ring back. Nothing is masked or rented, which is also why people answer more readily than they do for unknown landline series.
The call is marked as not answered and the lead stays in the list. A call-again rule can bring it back for up to three more rings, after the list or after a set time, and leads that never connect are collected separately so they can be tried another day.
Yes. Leads arriving from a Google Sheet, a website form or an API connection can be assigned in turn to the callers on the account, round robin, or only to the people you select. Each telecaller then finds new enquiries in their own queue, ready to call.
Yes. A WhatsApp message can go after a call, with a different text for missed, outgoing and incoming calls, either through the WhatsApp Business API or by opening WhatsApp with the message ready to send. Quiet hours and a per-number cooldown stop the same person being messaged twice.
Yes. Calls made, calls connected and talk time for every telecaller are visible in the team call log on the phone and in the Web CRM, updated as the day goes on. A ranking board shows who is ahead, which is often enough to keep a calling target on track.
Any Android phone on version 8 or newer, with the app set as the phone dialer so it can ring the list and show leads during calls. iPhones can use the app for leads, stages and reminders, but Apple requires a tap for every call, so hands-free list calling is an Android feature.
Yes. On a dual-SIM phone you choose the SIM once, and every call in the session goes out on it. That keeps business calling on the business number while the other slot stays personal, and each call is labelled with the SIM it used.
The calls run on each telecaller's own voice plan, so there are no per-minute charges. RMDialer is ₹159 per user per month on the yearly plan in India, with lower team rates from ten users ($29 per user per year, or $12 per user for 3 months, outside India), and all features can be tried free for 3 days.
Yes, with the Chrome extension. Click a number on a web page, in the Web CRM or on WhatsApp Web, and the call rings out from your phone on its SIM. The conversation happens on the phone, and the call is saved to the lead like any other.
Calling people who enquired with your business, one at a time from your own mobile, is an ordinary phone call; the CRM only removes the typing. Promotional calls to numbers on the do-not-disturb register, recorded-message calls and silent calls are what Indian rules restrict. This is general information, not legal advice.
The business dialer is free forever with no account and no expiry: the keypad, contacts, caller ID, the call log and your call analytics, plus free WhatsApp sends every day. A plan adds the customer record after every call, follow-up reminders, list auto dialing, your team and WhatsApp automation.
Free WhatsApp sends every day with a free account: 15 a day for your first 15 days, then 3 a day. The dialer itself needs no login at all.
