A SIM-based call management CRM ties each call on your team's own SIMs to the lead it was about. RMDialer does it on Android: the call ends, the stage moves, the next follow-up is booked.

Short answer
A SIM-based call management CRM is software that connects the ordinary mobile calls on a team's own SIMs to the customer records they belong to, so every call moves a lead forward instead of living only in a phone's call history. RMDialer is one for Android: the call is filed under the lead, the stage and the next follow-up are set before the next call, and it costs ₹159 per user per month on the yearly plan in India, or $29 per user per year, or $12 per user for 3 months, outside India.
Key takeaways
Six things a team that sells on its own mobiles stops losing once every call writes into the lead it was about.
The status and the follow-up date are asked for while the conversation is still fresh, so a lead never sits at "spoke, will see" for a month.
Open any customer and the calls, notes, status changes and reminders are in one line of time, with who made each call.
Calls leave from the salesperson’s own SIM, so a purchase officer who saved that number picks up instead of ignoring a strange one.
An enquiry that rang while someone was busy appears as a callback with the lead attached, rather than a red dot that slides off the screen.
How many leads moved forward today, which ones are overdue and who called whom is on the office browser without a meeting.
There is no virtual number, no exchange and no per-minute meter. The phones and voice plans the team already pays for are the whole telephony.
A conversation on a salesperson's mobile used to end with nothing written anywhere. Here is everything a single call now leaves behind, in the order it happens.
The number is matched to the customer before anyone touches the screen. Incoming or outgoing, answered or missed, the call is filed under that person and not in a loose list of digits.
Two taps after hanging up set where the deal now stands: demo booked, quotation sent, negotiation, won or lost. Your own pipeline names, in your own order, with the change dated.
A typed or spoken remark keeps what was said: the model they asked about, the rate they were quoted, the person who signs the order. It shows up on screen the next time that number rings.
Pick tomorrow, next week or an exact time, and the reminder rings like an alarm on the salesperson’s phone, even when it is locked. Overdue follow-ups carry into today until somebody closes them.
When someone is on leave or a territory is reshuffled, the manager moves the lead to another caller. The new owner inherits every call and remark, and the transfer itself is kept on record.
Calls, connected calls, talk time and status changes roll up per person and per day. Leads that were called many times and never connected are gathered as lost leads for a second attempt.
Open one customer and read the whole relationship: where they came from, their stage, every remark and follow-up, and the calls made from each salesperson's SIM.
This is the view a sales head uses before a review call with a big customer. The source shows which campaign brought the enquiry, the stage shows how far it has gone, and the journey shows every touch in order, including the remark a junior made three weeks ago that nobody passed on. A manager can transfer the lead from the same page, and the call buttons ring out from the phone. The calls behind this record are counted team-wide on the SIM based call management system, and the customer file itself is described on the SIM based CRM page.
Not a feature list. The question that decides whether a sales record is still true after a month of calls is who writes into it, and how soon after the call.

Real businesses, real numbers: how owners and sales teams across India and 12+ countries use RMDialer every day.
“Pickup calls, rate enquiries and account follow-ups from one phone. Missed calls during dispatch hours become call-backs instead of lost customers, and the monthly account customers get their reminder. Kannada interface. Call log backup to the account means a new phone starts where the old one stopped.”
“For a clinic the win is call management: every missed call at the front desk becomes a call-back reminder, and the patient's last visit remark shows when they ring again. Appointment reminders go on WhatsApp automatically. Our no-shows dropped noticeably in two months.”
“Quote-and-chase business. Every enquiry gets a quote remark and a call-back reminder, and the ones we lost show up in the lost leads list for a discount call next month. Auto WhatsApp sends the quote PDF after the call. Would like a Telugu voice note feature, otherwise very good call management app.”
“Rebooking is our revenue. Every client who visits gets a reminder call 4 weeks later, set from the after-call screen in two taps, and the festive offer goes as a WhatsApp broadcast to the call log. My receptionist learned the app in an hour. The backup meant nothing was lost when her phone broke.”
“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.”
“Most CRM tools here are built for a desk. Our brokers sell from their phones, so a telecalling CRM inside the dialer made sense. Leads from Facebook ads land in the app, the auto dialer calls them, and the tripping schedule rings each broker. Tagalog interface, own Globe SIM, no VoIP number for clients to distrust.”

A medical and biomedical equipment dealer in Vijayawada, five sales executives on the road and a service desk in town.
The dealer sells patient monitors, ventilators and operation theatre lights to nursing homes and district hospitals across the Krishna and Guntur belt, and runs annual maintenance contracts on what it has installed. Almost every deal starts and ends on a phone call: a purchase officer asking for a revised quotation, a hospital administrator chasing a demo unit, a tender clerk confirming a date. Those calls happened on the executives' own mobiles, and the only record was whatever each person chose to tell the office on Saturday.
The cost showed up in the AMC renewals and the tenders. A nursing home in Machilipatnam had called twice about a quotation, once while the executive was driving and once to a colleague who did not know the history. By the time anyone rang back, the order had gone to another dealer. Nobody had been careless; the call simply had no place to land.
After the change, each executive's calls file themselves under the hospital they belong to. A call cannot be closed without a stage, so "demo fixed for Thursday" becomes a reminder that rings on Thursday morning, and the service engineer who takes over an AMC lead sees every quotation discussed before him. The owner reviews overdue follow-ups on the office computer each evening instead of phoning five people, and missed calls from purchase officers are returned the same day because they sit on the lead, not in someone's pocket.
Four kinds of business that should buy something else, said plainly so nobody pays for the wrong setup.
If your work is mostly outbound, a telecaller working through an enquiry list hour after hour, the calling side is covered on the SIM-based calling CRM page. For the same idea without the SIM angle, call management CRM explains the category, and employee call tracking goes deeper on the per-person numbers a manager watches.
Some people write it with a hyphen, SIM-based, and some without, SIM based; a few drop the word "based" and search for a SIM call management CRM. "Software" is the office view, where an owner reads stages and overdue follow-ups; "app" is the salesperson's view, where the call is made and the lead is updated. They name one tool, and this page describes both halves of it.
You will also see it called sim based call management crm, sim based call management crm software, sim based call management crm app and sim call management crm. They describe the same thing, so whichever phrase brought you here, this is the page for it.
The call ends and the status sheet is already open: choose where the deal stands now, and the lead’s stage changes with today’s date on it.
Choose when to ring again and the reminder is saved on that lead, set to ring at the time you picked.
Each salesperson’s calls, connected calls and talk time sit in the team call log, so the evening review is reading, not asking.
For a small business that sells on the phone, RMDialer is the best SIM-based call management CRM: a call on any salesperson's SIM lands on its lead, and the stage and next follow-up are asked for while the conversation is fresh. Teams keep the Android handsets they have, the owner gets a Web CRM, and a seat costs ₹159 a month on yearly billing in India ($29 per user per year, or $12 per user for 3 months, outside India).
Yes, RMDialer is a SIM-based call management CRM. Installed as the phone app on Android, it files each incoming, outgoing and missed call against the customer it came from and keeps that customer’s stage, remark and next reminder current. Owners open the same records in a browser; the calls themselves remain ordinary SIM calls from your own numbers.
A call log app shows that a call happened. A call management CRM also records what it meant: the customer it belonged to, where the deal moved, what was promised and when to ring again. The log answers "did we call?", the CRM answers "what happens next with this customer?".
The call itself is filed against the lead automatically, with its time, length and the SIM it used. The outcome takes two taps on the sheet that opens when the call ends, and a remark is optional, typed or spoken. Nothing has to be copied from the phone into a computer afterwards.
Yes. A missed call is matched to the lead and shown as a callback, with one tap to call back on the SIM of your choice or to send a WhatsApp message. It stays visible until somebody returns it, which is how enquiries that rang during a busy hour stop disappearing.
Yes. Create the stages your sales really go through, rename them, give each a colour and drag them into order. A stage that leads still sit in cannot be deleted by mistake, and every change of stage is kept in the lead’s history with its date.
Yes, once RMDialer is the phone app. An incoming call shows the lead’s name, current stage and last remark on the ringing screen, so the salesperson answers knowing it is the purchase officer who asked for a revised quotation, not an unknown number.
Connect a Google Sheet or a REST API that your ad forms or website already fill, and new rows arrive as leads on a schedule, tagged with their source. Excel, CSV and JSON files can be imported on the phone too, and duplicate numbers are dropped on the way in.
Yes. A lead can be transferred to anyone on the team, one at a time or in bulk, and the history travels with it: every past call, remark and reminder. The transfer is recorded, so it is always clear who handled the customer and when the change happened.
Call recording is supported, and our team sets it up with you during training, because what a handset allows differs by brand. The recordings the phone makes are matched to the right call and appear on that lead, so a manager can hear the conversation behind a stage change.
No. The calls run on the mobile voice network, so they work wherever there is signal. Stage changes, remarks and reminders are saved on the phone first and sent to the account when data returns, so a day in a basement store room still ends with every call on its lead.
Yes. Numbers marked as excluded are never uploaded and never receive automatic messages, and on a dual-SIM phone you choose which SIM’s calls are backed up. A salesperson’s family calls stay on the phone and out of the company’s records.
The calls cost what your voice plan already charges, usually nothing extra. 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). Every feature can be tried free for 3 days, and there is no per-minute charge because no line is rented.
Yes. Leads export to a CSV file that follows whatever filter is on screen, so you can take out one stage, one source or one salesperson’s leads. The data stays yours, and the same records remain available in the Web CRM.
Partly. The iPhone app handles leads, stages, remarks, reminders and WhatsApp, but Apple keeps the phone’s call history closed to every app, so iPhone calls are not filed against leads by themselves. Teams that rely on automatic call records use Android phones for calling.
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.
