Trying to educate myself with your help
so the IMEI can be transmitted via the gps chip if there isn’t a Sim or no data credit ?
As soon as a phone is powered on it pings the nearest base station (phone mast) which in turn does a ping to all the HLRs (home location registers) of which there are only small numbers spread around the providers. Your HLR is totally unrelated to where you are located. Once you are identified, by your IMEI number, at any HLR, you will be connected to SIM card providers service - or ignored. But your presence will still be recorded.
