SIM based calling CRM for teams that call from mobile phones

What is a SIM based calling CRM?

A SIM based calling CRM is mobile CRM software that places calls over the phone’s own SIM card and logs every call to a lead. AutoDial CRM is a SIM based calling CRM, part of its wider telecalling CRM, that calls from each employee’s own number.

AutoDial CRM keeps the phone network your team already pays for and adds the record-keeping on top. When a salesperson dials, the call leaves through the SIM inside their handset, so the customer sees an ordinary mobile number and the minutes come out of the existing mobile plan. No virtual number is rented and no internet connection carries the voice. Once the call ends, the app stores its direction and the SIM it went out on against the matching lead, and a short after-call sheet asks how it went, what to note and when to call next. On Android the app can take over as the default phone app, so calls typed by hand on the keypad are captured as well as dialer sessions; the iPhone app has every feature except the phone’s call log. Each employee’s calls then sync to a single owner account. All product details here were rechecked with AutoDial CRM’s features on 14 October 2026.

SIM based calling CRM benefits

• A number customers know

  Leads see a regular mobile number they can save and ring back later.

• Nothing to rent

  No virtual numbers, gateways or desk handsets, only the SIMs already in use.

• Calls wherever there is signal

  Field staff call from a car park or a client site, not only from office Wi-Fi.

• Correct SIM on every record

  Each call keeps the SIM it really used, so business and personal lines stay apart.

• One account for the owner

  Every handset's calls arrive in the same place, without anyone exporting a log.

SIM based calling CRM: what happens on each call

A SIM call in AutoDial CRM moves through five short stages, and only the first one needs the salesperson to do anything.

• Dial: tap a lead, run the auto dialer through a queue, or click a number in Chrome so the phone dials it. On a dual-SIM handset the SIM is picked per call, or one SIM is fixed as the business default.
• Ring: the app names an incoming number from the leads, clients and contacts you hold before trying anything else, and the full-screen call screen shows the name, current status and last remark.
• Talk: the complete lead record opens during the call, with earlier calls, chats, remarks and reminders in tabs.
• Save: two taps on the after-call sheet record the outcome, a note and the follow-up date. A few handset makers file call directions under private codes; the app learns them, so the call type on the record is right.
• Sync: calls and notes reach the account in the background, a full sync runs each time the app opens, and a sync log shows anything that needs a retry.

When the handset’s built-in recorder keeps a file, the app pulls it in by itself; see the call recording CRM page for how that works.

SIM based telecalling CRM for a whole team

For an owner, the point of a SIM based telecalling CRM is seeing calls made on many phones without asking anyone for screenshots. Assigned leads land in a pending queue that belongs to one person alone, and every employee’s calls appear in the owner’s team log. If the network cuts a dialer call before it rings, the app tries that number again up to 2 times before the lead counts as not reached.

Many staff carry one phone with a work SIM and a family SIM. The admin chooses which SIMs back up, can restrict backup to office-hours calls or to customer calls only, and can mark numbers as excluded so neither backup nor any automation touches them. The same handset also works as an auto dialer app, and owners who want the reporting side in depth can read about the call tracking app.

SIM based calling CRM vs cloud calling

SIM based calling CRM setup

1. Put AutoDial CRM on every sales phone and let it take over as the dialer during the guided setup.
2. Where a phone holds two SIMs, fix the work SIM as default or keep choosing the SIM call by call.
3. Choose which SIMs back up, and exclude family or personal numbers.
4. Bring leads in from an Excel or CSV file or a Google Sheet, and share them out so every person has a queue.
5. Make a few test calls and check that each one lands on the lead with the right SIM name.

SIM based calling CRM limits

A SIM based calling CRM gives every salesperson their own number, which is the wrong fit when customers must reach one shared company line that rings several people. AutoDial CRM has no IVR menus, no virtual numbers and no inbound routing, so a busy support desk is better served by cloud telephony. Calls depend on mobile coverage and each SIM’s tariff, including roaming. Recordings exist only when the handset itself records. Apple does not let iPhone apps read call records, which is why capturing every call automatically requires an Android phone. Rules on sales calls vary from country to country; check your own before calling a new list.

SIM based calling CRM example

An illustration, not a named customer. A real estate brokerage in Chennai, India, has 8 sales executives who each carry a company dual-SIM phone: SIM 1 is personal and SIM 2 is the office line. Before the switch, the manager learned about calls only from what people remembered at the evening meeting. She installs AutoDial CRM on all 8 phones, makes SIM 2 the default line for work and backs up only that SIM. Each morning every executive gets about 40 portal and website leads in a personal queue and calls them from SIM 2. A buyer who rings back at night is named on screen with the last remark, such as “Wants a 2BHK near OMR”. At the end of the week the manager opens the team log and sees each person’s calls without a single spreadsheet. Eight users on the yearly plan come to ₹1,752 a month, about $22.32.
