https://devzone.nordicsemi.com/f/nordic-q-a/52868/are-nbiot-cat-m1-transmissions-permitted-on-aircraft-in-flightIs anyone aware of the status of NBIoT / CATM1 use on flights? Are they covered by the various &quot;mobile phone&quot; limitations of use? I&#39;m referring to the use of a product containing an NRF91 device. Thanks in advance.en-USTelligent Community 13Sat, 05 Oct 2019 09:58:24 GMThttps://devzone.nordicsemi.com/thread/213490?ContentTypeID=1Sat, 05 Oct 2019 09:58:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:273553c3-44aa-4963-b567-d4025a0ee4c8mhibbett<p>Thanks&nbsp;<span>H&aring;kon, appreciate that, just interested whether anyone had looked into this already.&nbsp;</span></p> <p><span></span></p> <p><span>Regards,</span></p> <p><span></span></p> <p><span>Mike.</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/213397?ContentTypeID=1Fri, 04 Oct 2019 11:36:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:164b247c-8181-4667-977b-c342a09bc801H&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>That is a question towards each individual airline carrier that you are using, and not something that we can answer.</p> <p>What I can say is that we support flight mode, by issuing AT+CFUN=4.</p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>
