Please see&nbsp;<a title="Credential storage management %CMNG" href="https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/mob_termination_ctrl_status/cmng.html?cp=2_1_3_25">%CMNG</a>/<a title="Set command" href="https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/mob_termination_ctrl_status/cmng_set.html?cp=2_1_3_25_0">Set command</a>.<br />You could use AT+CFUN=4 to stop the modem, or not start it in the first place (although in some samples it is started during boot-up, before the application).</p> <p>-Amanda H.</p><div style="clear:both;"></div>
