SIM based telecalling CRM

Customers stopped answering, and the number they were ignoring was one you rented.

People answer numbers that look like people. With Telodial, the telecalling CRM, every call goes out on the SIM already in your caller phone.

No virtual numbers, no IVR to configure, no per-minute telephony bill, and no new contract. Your own number rings on the customer side, at your own tariff.

Free for 3 days, every feature, no card needed.

A call going out on the phone own SIM with lead context

What is a SIM based telecalling CRM?

A SIM based telecalling CRM places its calls through the SIM card in the phone rather than over the internet, so the customer sees an ordinary mobile number and the call costs whatever your existing plan costs. Telodial works this way by design. There is no virtual number to rent, no IVR to configure, no minute-by-minute telephony invoice and no separate contract to sign, which removes both a monthly cost and a setup project. The practical difference shows up in answer rates: an unfamiliar landline-style number reads as a call centre and gets ignored, while a normal mobile number gets picked up, and a customer can call it back later and reach the same person. The trade-off is honest: one call at a time per SIM, which suits a team of two to fifty rather than a large contact centre.

  • Your own number on the customer screen, at your own tariff
  • No virtual number, IVR, VoIP account or per-minute bill
  • Calls keep working on a weak data connection
  • Customers can call the same number back and reach the same caller
Why teams switch

What it fixes in the first week

Today

Answer rates fall on rented numbers

An unfamiliar number that looks institutional gets ignored, and every ignored call is paid-for time producing nothing.

With Telodial

The call comes from your own mobile number, so it looks like a person calling and gets answered like one.

Today

Telephony bills arrive by the minute

Per-minute charges, number rentals and a plan that has to be topped up turn a fixed cost into a variable one you cannot forecast.

With Telodial

Calls run on the SIM plan you already pay for, so your calling cost stops moving with your call volume.

Today

Setup means a project

Numbers to provision, an IVR tree to draw, a routing table, a vendor call. Weeks before the first customer is dialed.

With Telodial

Install the app, sign in, import the list and call. The phone in the pocket is the entire infrastructure.

How it works

Three steps, and no training day

  1. 1

    Keep the phone and the SIM

    No new hardware, no new number, no porting. The Android phone your caller carries and the SIM already in it are what the system runs on.

    The app on a normal Android phone
  2. 2

    Set it as the dialer

    One tap in the guided setup, so incoming calls show the customer context and the after-call sheet appears on every business call, not only the ones started from a list.

    Setting the app as the phone dialer
  3. 3

    Choose which SIM does business

    On a dual-SIM phone, pick the SIM per call or set a default business SIM, so personal and business calling stay on separate numbers and separate bills.

What callers and owners tell us

I was quoted five times this per user elsewhere, for less. I kept looking for the catch and the catch was that there is no add-on tier.
Prashant U.Proprietor, PuneAug 2026
One renewal we would otherwise have missed covered the whole year for the whole team. That is the honest arithmetic of it.
Devendra K.Insurance advisor, PuneAug 2026
Ninety calls a day was our ceiling for years. We touched a hundred and seventy in the second week, on the same list and the same people.
Farida S.Team lead, outbound sales, HyderabadJul 2026
Admission season is eight weeks of calling. Last year we tracked it in three sheets and lost count. This year one queue, one number, no arguments.

Questions

SIM based CRM: what people ask

What is the difference between SIM based calling and a cloud dialer?

A cloud dialer places calls over the internet from a rented virtual number and bills by the minute. A SIM based telecalling CRM like Telodial dials through the SIM in the phone, so the call is an ordinary mobile call on your own number and your own plan.

Why do answer rates matter more than dialing speed?

A parallel dialer that reaches nobody is slower than a single-line dialer that gets answered. In India an unfamiliar institutional-looking number is routinely ignored, so the number displayed affects conversion more than the calls-per-hour figure.

Does it work without internet?

The calling does, since these are ordinary mobile calls riding on the SIM rather than on the network. A connection is what copies records up for the dashboard to read, and whatever a caller captures while offline waits on the handset until the signal comes back.

Can I use two SIMs?

Yes. Choose the SIM for each call, or set a default business SIM so every business call goes out on the same number and the personal one stays personal.

Do I need a separate business number?

No, though many teams do give each caller a dedicated work SIM so that customers calling back reach the right person and the bill separates cleanly.

What about a large call centre with parallel dialing?

One SIM makes one call at a time, so this is the honest fit for a team of roughly two to fifty callers. Above that, a predictive setup with virtual numbers may genuinely suit you better, and we would rather say so here than after you pay.

Are there per-minute charges from Telodial?

None. You pay per user per month for the software; the calls are billed by your mobile operator on the plan you already have.

Will a SIM based CRM work for fifty callers?

Yes, with fifty phones and fifty SIMs, which is how most Indian teams of that size already work. Beyond roughly fifty seats on cold outbound, a predictive cloud setup may genuinely suit you better, and we would rather say so on this page than after you have paid.

Do I need to port my number?

No. Nothing about your numbers changes. The app uses the SIM that is already in the phone, on the plan it already has.

What if a caller uses their personal SIM by mistake?

Set a default business SIM per phone and every business call goes out on that number. On a dual-SIM handset the caller can still choose per call when they need to.

What you give up with SIM based calling, and why most small teams take that trade

Updated 6 September 2026

The case against SIM based dialing is real and worth stating: one SIM makes one call at a time. A cloud platform can open several lines per agent and connect whoever answers, which on a large floor produces measurably more conversations per hour. If you are running fifty or a hundred seats on outbound campaigns to cold lists, that arithmetic is likely to win, and a SIM based tool is the wrong shape for you.

For a team of two to fifty calling its own enquiries, the arithmetic reverses. Throughput is not the constraint; being answered is. A number that reads as a call centre is ignored by exactly the people you most want to reach, and no dialing speed compensates for a conversation that never starts. Your own mobile number is answered, can be saved by the customer, and can be called back to reach the same person, which is worth more than a second parallel line.

The cost structure differs just as sharply. Cloud calling adds number rentals and per-minute charges, so the bill grows with the work. SIM based calling runs on the plan you already pay for, which makes the software a fixed cost per caller and leaves the calling itself where it always was. That predictability, plus starting on Monday instead of after a provisioning project, is usually what decides it.
