Hi,
I have been trying to get the ppp-out1 interface (KNOT RouterOS 7.7), configured and running with an NB-IoT sim from Vodacom in South Africa.
The error I get is +CME ERROR: 3, meaning: Operation not allowed. The error is when running the command AT+COPS=? (This does take several minutes to come back with the error)
I have done a few tests together with the sim provider - The KNOT seems to be having an issue registering to Vodacom. The APN setting is correct.
Can you kindly please advise what else can be done as urgently need to get the NB-IoT connection working.
Here are other AT command outputs.

Re: Narrow Band not connecting on Mikrotik KNOT
Hi,
After further investigation - I decided to do a Reset Configuration. The NB-IoT connects to the Provider. One step forward.
However, the ppp-out1 reacts strangely: It seems the ppp-out1 is not fully connecting. In the log the ppp-out1 goes from : waiting for packets -> initializing -> terminating... - could not acquire serial port -> disconnected -> connecting...
Still investigating this issue.

Re: Narrow Band not connecting on Mikrotik KNOT
Did you ever get this working? I am also trying to get AT&T NB-IOT sim working with a BG77 modem in a KNOT...
I'm running into a similar issue encountering "+CME ERROR: 30" when attempting to set the PDP context (AT+CGACT) or when trying to when setting the operator manually (AT+COPS).
Also I am unsure why I keep getting "setting APN Failed" in the log...
