Problems with network connection

[Olga San]

I cannot connect to the radio network. Is there an AT command sequence starting from initializing the modem till attachment to the network ?

Updated AT command sequence. The following commands need to be executed as displayed here:

// Turn Off Radio (IMPORTANT)

AT+CFUN=0

// The following commands need to be executed only once

AT+QCFG=“nbsibscramble“,0

AT+CPSMS=0,“00000001”,“00000001”

// !-> Reboot and turn off Radio (AT+CFUN=0)!

AT+QCFG=“band“,0,0,80,1

AT+QCFG=“nwscanmode“,3

AT+QCFG=“nwscanseq“,030201

AT+QCFG=“iotopmode“,1

AT+QCFG=“servicedomain“,1,1

AT+QCFG=“gprsattach“,0

// Turn on Radio

AT+CFUN = 1

// APN

AT+CGDCONT=1,“IP”,“internet.nbiot.telekom.de”

AT+COPS=?

AT+COPS=1,2,“26201“,9

// Check if modem is attached

AT+CGATT?

// Check if modem is registered correctly. Expected result is : +CEREG: 0,5

AT+CEREG?

What is the CGDCONT for the US? Is any thing else different for the US?

Dear Pete,
thank you for your question. It will be answered soon.

The command for the US is:
