What does your cell phone send to Google or Apple?

We investigated what data iOS on an iPhone shares with Apple and what data Google Android on a Pixel phone shares with Google.

We found that even when minimally configured and the phone is idle, both iOS and Google Android share data with Apple/Google on average every 4.5 minutes.

The phone’s IMEI, hardware serial number, SIM serial number and IMSI, and phone number are shared with Apple and Google.

Both iOS and Google Android transmit telemetry, even when the user explicitly opts out.

When a SIM is inserted, both iOS and Google Android send details to Apple/Google.

iOS sends the MAC addresses of nearby devices to Apple, along with their GPS location.

The solution will never come from corporations, but from humans who respect themselves:

When you download something from iTunes, you agree that Apple may collect, store, and share “precise location data, including the real-time geographic location of your computer or Apple device.”

There is no way to opt out of this data collection without giving up the ability to download apps.

It also does this when running programs.

In the modern more controlled versions of their systems, it is impossible to read a digital book without sending the localized location.
