[How to] Find out (lat,lon) of a device using OpenCelliD csv with MCC,MNC, LAC, Cellid

I have an offline machine where I have to calculate latitude and longitude of a device, I have MCC, MNC, LocationAreaCode and Cellid.

I did some tests on unwiredlabs api using GSM and i think its fairly accurate, I thought using the DB i’d get 1 to 1 mapping of the cells, but I can’t find my values in the csv
I downloaded the opencell id from here

I’m kind of new to this data so if someone could guide me on how to calculate Latitude of the device using mcc, mnc, lac, and cellid
