How to prevent my personal calls from getting synched with TeleCRM

Work sim: All calls are tracked
Personal sim: Only call to and from existing leads are tracked. I.e. any call to unknown leads are not tracked!
Blocked sim: No calls are tracked

It’s very simple you just have to put your personal sim card in blocked mode

In the TeleCRM app go to side nav > Call tracking > Sim card manager

Now select your personal sim and put it on blocked mode
