silent SMS?</a>

<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 received by the phone,
and they don't have to even be a silent SMS; it wouldn't be much different than
receiving an unsolicited spam SMS!</p>
<p>GrapheneOS always considers the network to be hostile and does not implement weak

of the core tenets of GrapheneOS is being honest with users and avoiding scams/frills
based around marketing rather than real world privacy/security threat models.</p>

<p>Even if interception of the connection or some other man-in-the-middle attack along
the network is not currently occurring, the network is still untrustworthy and
information should not be sent unencrypted. Legacy calls and texts should be avoided
as they're not secure and trust the carrier / network along with having weak security
against other parties. Trying to detect some forms of interception rather than dealing
with the root of the problem (unencrypted communications / data transfer) would be
foolish and doomed to failure.</p>
<p>Receiving 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> including yourself. Cellular triangulation will happen regardless of whether
or not SMS texts are being sent or received by the phone. Even if an SMS did serve a
useful purpose for tracking, a silent SMS would be little different than receiving
unsolicited spam. In fact, sending spam would be stealthier since it wouldn't trigger
alerts for silent SMS but rather would be ignored with the rest of the spam. Regardless,
sending texts or other data is not required or particularly useful to track devices
connected to a network for an adversary with the appropriate access.</p>
