<a href="#cellular-tracking">What does GrapheneOS do about cellular tracking and
silent SMS?</a>
</h2>
<p>GrapheneOS always considers the network to be hostile. Merely getting a silent SMS is
not a good indicator of being targeted by your cell carrier, police or government
because <em>anyone on the cell network can send them</em>. Cellular triangulation will
happen regardless of whether or not SMS texts are being sent or recieved by the phone,
and they don't have to even be a silent SMS; it wouldn't be much different than
recieving an unsolicited spam SMS!</p>
<p>Activating airplane mode will fully disable the cellular radio transmit and recieve
capabilities, which will prevent your phone from being reached from the cellular
network and stop your carrier (and anyone impersonating them to you) from tracking the
device via the cell network. On currently supported devices, the code for Wi-Fi and
cellular radios is separately sandboxed, and while airplane mode is on, the phone may
still be connected and used on WiFi. MAC Addresses on Wi-Fi are randomized.</p>
