    do you have any thoughts about why they might be getting a NOSERVICE message?

    I don't know in detail, but what I am missing in the example code is an AT command "AT+COPS" to manually register at the network. I did my tests with NB-IoT capable SIM cards by Vodafone (Germany) and 1NCE. So maybe it is the missing step to register at the network.

    I just updated my MQTT via NB-IoT example a few days ago, you can see the sequence of AT commands there. Check it out at
