Thanks for the reply.
The AT commands from the manual part IV do not work for the 7000E. The AT+CIPSTART at the bottom of my post is my best guess for the replacement. This is used in the Adafruit Fona Arduino library in a similar way (but for an older Simcom device).
From the last post of Remco it looks like he has the same problem. We can attach to the network but cannot send data. Is there a way to find out why the connect fails and the whole IP subsystem is deactivated (e.g. find out from logging on your side)?
BTW, many of the AT commands from the manual part II do not work for the 7000E. It looks like this was tested on a ublox. Can you please add to the manual on which devices these commands were tested. The AT commandset has many vendor specific extensions. New users may not be aware of this. The posts of “DutchDev” and “Marcel Duijnisveld” contain the commands that give you an IP address on the 7000E.

I have a SIM7000E board. I setup a NB-IOT connection and received an IP adress.
To come at this stage, I entered the commands as explained in the posts of “DutchDev” and “Marcel Duijnisveld”.
The final checks look like this:

AT+COPS?
+COPS: 1,2,“20416”,9
OK

AT+CGPADDR
+CGPADDR: 1,10.128.0.xxx
OK

But I cannot setup a UDP connection, it deactivates the connection, Did anyone come any further and managed to send data to the T-Mobile Device Registration UI? I am also a bit puzzled by the API credentials that I received in the portal. The “Getting Started” is not using them.

AT+CIPSTART=“UDP”,“172.27.131.100”,7000
OK
STATE: PDP DEACT
CONNECT FAIL
