How SIM-based Call Management Software Works

SIM call logging runs quietly on the rep's Android phone and reads native call events the moment they happen

Call happens on the rep's mobile SIM

Reps call from their normal dialer using their existing mobile number. There's no app to open first and no virtual number to dial through.

CallAnchor captures the call automatically

As soon as the call ends, CallAnchor's automatic call logging picks up the call duration, timestamp, direction, and (where enabled) the recording.

The number is matched to a CRM record

360 CallAnchor checks the number against existing leads, contacts, accounts, or deals. No match? A new record is created automatically.

Call activity syncs into CRM

The logged call, recording, disposition, and notes push into the right CRM record as an activity. No separate app, no duplicate entry.

A rep makes an outgoing call from their own mobile SIM using the native dialler, with no VoIP or virtual number involved

FAQs About SIM-Based Call Logging

What is SIM based call logging software and how is it different from VoIP call tracking?

SIM based call logging software captures call activity directly from calls made on a rep's mobile SIM, not through a virtual number or cloud dialer. The call happens on the rep's own number over the mobile network. 360 CallAnchor reads the call event the moment it ends and syncs the record to the CRM, without requiring a separate calling app or internet connection during the call.

Does SIM based call tracking software work without internet during the call?

Yes. Logging happens on the SIM network, not over data. If the rep has no internet when the call ends, the record queues on device and syncs to the CRM automatically when connectivity returns. Nothing is lost.

Is 360 CallAnchor SIM based call recording software or does recording require a separate tool?

Recording is built into 360 CallAnchor. Business call audio is captured on the device and attached to the CRM record once the disposition is saved. Recording should follow applicable consent laws and your internal company policy. Admins control which users and call types are recorded

What happens when a caller's number is not in the CRM?

360 CallAnchor checks every incoming number against existing leads, contacts, accounts, and deals in the CRM. If no match is found, a new lead record is created automatically and the call is attached to it. No manual record creation needed.

Is 360 CallAnchor SIM based call management software or does it replace the CRM entirely?

It is SIM based call management software, not a CRM replacement. 360 CallAnchor captures call activity from the rep's SIM and pushes it into the CRM your team already uses. Your CRM stays the system of record. Nothing is stored on 360 CallAnchor's servers permanently.

Does GSM call logging software work the same for field reps and desk-based teams?

Yes. Because logging happens on the SIM network rather than over the internet, field reps in low-connectivity areas generate the same complete call records as desk-based reps on Wi-Fi. Managers get one consistent dataset across the whole team, not two separate tracking behaviours to reconcile.
