The only way to address GPS and cellular tracking is to avoid any device with a baseband. So in fact it is either-or in this case.

The only way to address GPS and cellular tracking is to avoid any device with a baseband. So in fact it is either-or in this case.
- jmiserez 8y agoThe upcoming Librem 5 phone has a hardware killswitch disconnecting the baseband completely. It's not a mInstream device though. Alternatively airplane mode might work too on regular phones, but personally I wouldn't trust it 100%.
- paavoova 8y agoThe problem is doing that ensures your mobile device is useless as, well, a real-time communications device. No immediate calls, no SMS, no internet and associated apps without wifi around - how many people are going to enable this? The answer is none, even for the very customers Purism wishes to attract. Because people already wishing to do so can put their phone, any phone, in a Faraday cage, but that seemingly hasn't taken off. Secondly, my concern would be the cellular network automatically flagging you for suspicious activity, especially in an area know to have good coverage. It would certainly look suspect for a device to periodically pop up, send some traffic, then disappear once again.

- imglorp 8y agoYes and it's not even malicious basebands, it's any at all. If you want to participate in the cell network in any way, even if you write your own baseband, the network will still be able to report your approximate position using UTDOA, CGI or CGI-TA, ECID, etc. The network needs to gather at least your id/plan ($) and CGI (which antenna and what power) as part of its normal process to give you service.
