I am trying to get rayhunter, but I am confused about a few things. What kind of hardware may be used? The Orbic RC400L advertises itself as being for Verizon network only, which I am not going to use. Does the rayhunter software allow it to work on arbitrary networks?
Furthermore, I don't see a good way to acquire such a device. They aren't sold locally as far as I can tell. On amazon they are available, though expensive. However, that would mean losing any form of privacy. I don't need it to be completely anonymous—someone looking at the location could probably see home and work easily enough—but better than amazon would be much preferred.
Are there any alternate devices that are known to work well in Canada? I will be keeping the device powered off most of the time anyways, (so as to hide my location) but it must be reliable when I need it.
EDIT: eSIM support is a plus, but not required
To the extent that you still need to use standard apps, consider disabling your advertising ID. EFF has a guide to this at https://www.eff.org/deeplinks/2022/05/how-disable-ad-id-tracking-ios-and-android-and-why-you-should-do-it-now
This won't stop google of course. You should probably also install a firewall, like other people here have suggested. And keep in mind, disabling features entirely is different from not using them. For example, if location services is turned off, then even google maps doesn't know your location (in theory anyway), whereas if it is merely unused then google will still check periodically.
