how to get other people’s lac and cell ids with just one phone without having a relationship with the operator if they know the phone number they’re using.
You can’t. The device has to communicate the scanned cell info to you. (MCC-MNC-LAC-CID)

In my case, I’m wondering the location of the tower.
Here in Brazil, the MCC is 724, the MNC depends on the Operator, which in my case is the CLARO MNC = 05.
Unfortunately I can not go to the location to know the location of the towers. I’m getting the information through the Open Signal app.
Even with all the information (MCC-MNC-LAC-CID), I can not know the exact location of the tower.
You can input MCC-MNC-LAC-CID and get a result of the approximate position of the cell from OpenCelliD. There can be instances where that particular cell isn’t present in OpenCelliD database.
