https://devzone.nordicsemi.com/f/nordic-q-a/61097/nrf9160-dk-does-not-provide-the-iccid-integrated-circuit-card-idHow can I read the ICCID (Integrated Circuit Card ID) of the SIM-card? Normally (with competitive modems) I get the CCID by AT+CCID. The nRF9160 reponds with +CME: 0 (see below) 2020-05-06T14:32:25.264Z DEBUG modem &gt;&gt; AT+COPS?\x0D\x0A 2020-05-06T14en-USTelligent Community 13Thu, 07 May 2020 06:45:41 GMThttps://devzone.nordicsemi.com/thread/248619?ContentTypeID=1Thu, 07 May 2020 06:45:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bc06e418-fdc0-475b-8d47-a1ad11060d5aH&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> [quote user=""]2020-05-06T14:34:25.955Z DEBUG modem &gt;&gt; AT+CCID\x0D\x0A<br />2020-05-06T14:34:25.967Z DEBUG modem &lt;&lt; <span style="background-color:#ffffff;color:#ff0000;">+CME: 0</span>\x0D\x0A\x00[/quote] <p>Could you try this AT command instead?&nbsp;<a href="https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/general/xiccid_set.html?cp=2_1_2_8_0">https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/general/xiccid_set.html?cp=2_1_2_8_0</a></p> <p>AT+CCID isn&#39;t a listed command in our AT commands reference.</p> <p>&nbsp;</p> <p>However; It should not stop responding afterwards.
