https://devzone.nordicsemi.com/f/nordic-q-a/73340/nrf9160-registration-power-on-budgetHi, I noticed that if you send AT+CFUN=1 then AT+CFUN=4 more than 30 times in an hour the modem stops registering until the hour passes? Is this by design? Kind regards, Thomasen-USTelligent Community 13Mon, 29 Mar 2021 10:29:42 GMThttps://devzone.nordicsemi.com/thread/302341?ContentTypeID=1Mon, 29 Mar 2021 10:29:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0f6a8a38-d6e4-485e-9a72-186b20515323Carl Richard<p>Hi, Thomas!<br /><br /><span>The GSMA has specified a Radio Policy Manager (RPM) feature to protect the network from excessive signaling. In the case of connection requests(which will be initiated by CFUN=4 and CFUN=1) the default value is 30, which is also implemented in our modem firmware. Exceeding this limit will lead to a 1 hour ban from connecting to the network.
