The network doesn&#39;t explicitly tell that PSM is not supported as far as I know. You will need to check the output of the <a href="https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/nw_service/cereg.html">+CEREG command</a> to know if PSM is enabled or not.</p><div style="clear:both;"></div>
