Can not open PDP Context --> Always AT+QIACT Error

IoT Modules LTE Standard Module

Hello, I’m new to this area, I use the Quctel EG91-E

I tried to open a TCP connection according to the instructions,
but always get an error with AT+QIACT.

Who can help me? I think it’s probably just missing a instruction/setting.

here is my sequence of commands:

AT+CPIN?
+CPIN: READY
OK

AT+COPS?
+COPS: 1,2,“26201”,0
OK

AT+CREG?
+CREG: 0,5
OK

AT+CGREG?
+CGREG: 0,5
OK

AT+QICSGP=1,1,“internet.telekom.de”,“t-mobile”,“tm”,3
OK

AT+QICSGP=1
+QICSGP: 1,“internet.telekom.de”,“t-mobile”,“tm”,3
OK

AT+CSQ
+CSQ: 22,99
OK

AT+QIACT=1
ERROR

Thanks for the help in advance

Hi kernst,

I’m a little bit confused about your log.
It states that you are connected to DTAG (26201) and CGREG states, that you are in roaming (0,5).
In case you are roaming you might not use the Telekom APN at all.
Try to use the APN from your roaming SIM card.

In addition, the used APN - are you sure it has the .de at the end? You might try ‘internet.telekom’ only.

I did set it up like this:
at+cops?
+COPS: 0,2,“26201”,0
OK
at+cgreg?
+CGREG: 0,5
OK
AT+QICSGP=1,1,“soracom.io”
OK
AT+QIACT=1
OK
AT+QIACT?
+QIACT: 1,1,1,“10.206.150.238”
OK
