<h2><a href="#carrier-functionality">Carrier functionality</a></h2>
<p>GrapheneOS aims to work with all carriers that are officially supported by Google
on the stock operating system on Pixel devices. Wi-Fi Calling, VoLTE, Visual Voicemail,
MMS, SMS, Calling and 5G (SA and NSA) all are supported, however some functionality may
not be usable due to Google not supporting carriers on the stock OS officially or
due to GrapheneOS not shipping proprietary apps required in order for this
functionality to work on some carriers. GrapheneOS extracts CarrierConfigs, APNs,
modem configurations, Visual Voicemail configurations and MMS configurations from the
stock operating system to ensure users get easy carrier support that "just works".</p>
<p>Please note that in some regions, LTE is referred to as 4G.</p>
<p>Generally Visual Voicemail, SMS, MMS, Calls and VoLTE will work fine on GrapheneOS
with officially supported carriers by Google. Wi-Fi calling may vary due to a reliance
on proprietary Google apps which GrapheneOS does not ship.</p>
<p>If you are having problems sending or receiving SMS/MMS messages, we suggest that
you perform the following steps:</p>
<ul>
<li>Deregister your phone number from <a href="https://selfsolve.apple.com/deregister-imessage">Apple iMessage</a></li>
<li>Deregister your phone number from <a href="https://messages.google.com/disable-chat">Google Chat Features</a></li>
<li>Deregister your phone number from your carrier's RCS service</li>
</ul>
<p>If you continue to have problems despite following the instructions above or you
have another carrier related issue, we suggest that you perform the following steps:</p>
<ul>
<li>Some carriers require you to explicitly opt in to use services such as Wi-Fi calling.
Consult your carrier's documentation on the process for this or contact them.</li>
<li>Reset Mobile Network settings in Settings ➔ System ➔ Reset options ➔ Reset Wi-Fi,
mobile &amp; Bluetooth and then reboot the device.</li>
<li>USA users only: You may need to request your carrier to enable CDMA-less mode if
you have issues.</li>
<li>Follow your carrier's instructions for setting up APNs, this can be found in
Settings ➔ Network &amp; Internet ➔ SIMs ➔ Access Point Names</li>
<li>As a last resort you may need to ask your carrier for a replacement SIM card.</li>
</ul>
<p>GrapheneOS includes bypasses for carrier restrictions on APN editing, tethering via
USB, Ethernet, Bluetooth and Wi-Fi and the ability to disable 2G, actions which would not
have been possible on the stock operating system.</p>
