@Sven-Brandau said in Network time: Hello, is the feature ‘network time’ (3GPP 27.007 Ch. 8.15) for NB-IOT/Cat-M1 supported in the Deutsche Telekom mobile network? The NRF9160 SIP returns an error, while requesting the time. Also after a long time of being connected. Hi Sven, sorry that it took us so long. But now we have a clear statement from our experts that the network time feature is NOT supported in our network in Germany.

Hi Tibor, Did you succeed to connect? I want to use the Boron to.

Problem solved. It denpends on the sim card

It is true that there is no time synchronization in Germany. The CCLK feature does not work on the network in Germany. The manual of the n211 says it comes back with a +CCLK measage but in practice it only gives OK when this feature does not work on the network. Best Regards

Hi, what kind of SIM are you using? I’m asking because our m2m/IoT SIMs usually come with PIN disabled. For this reason, PIN handling is not included in our HW-library. Unfortunately, the module you are using does not support any management of facility locks, other than entering the PIN when the radio is turned. To proceed you should deactivate the PIN on the SIM on a different device. You can either try a smartphone or a different module which supports the management of facility locks. The required AT-commands for this are: AT+CLCK=“SC”,2 # Query status of SIM lock +CLCK: 0 # SIM is unlocked (1 would be locked) AT+CLCK=“SC”,0,“1234” # Remove SIM lock (for PIN 1234) Best regards

The command for the US is: AT+CGDCONT=1,“IP”, “iot.nb”
