I did some research and statistically every one in this thread (beside me) uses a mobile device with apple or google OS giving away their privacy freely
both iOS and Google Android share
data with Apple/Google on average every 4.5 min s. The phone
IMEI, hardware serial number, SIM serial number and IMSI,
handset phone number etc are shared with Apple and Google.
Both iOS and Google Android transmit telemetry, despite the
user explicitly opting out of this. When a SIM is inserted both
iOS and Google Android send details to Apple/Google. iOS sends
the MAC addresses of nearby devices , e.g. other handsets and
the home gateway, to Apple together with their GPS location .
Users have no opt out from this and currently there are few, if
any, realistic options for preventing this data sharing.
