Cannot connect to network using NB-IoT shield with Arduino Leonardo board

Hi,

I already review all of similar issues about my question and then try to use their suggestion. But, I still cannot connect to network and correct signal.

  1. Fetch the arduino source code from http://support.sodaq.com/sodaq-one/at/
  2. Flash the source code to Arduino Leonardo board
  3. Open the Serial Monitor in Sketch
  4. Set up the baud rate as 9600 and Enable the Both NL & CR option
  5. Send some AT commands to board.

The detail procedure is as below:
AT+NCONFIG?
+NCONFIG:AUTOCONNECT,TRUE
+NCONFIG:CR_0354_0338_SCRAMBLING,FALSE
+NCONFIG:CR_0859_SI_AVOID,FALSE

AT+CEREG=2
OK

AT+CSCON=1
OK

AT+CGDCONT=1,”IP”,”xxx”
OK

AT+NBAND=28
OK

AT+CSCON?
+CSCON:1,0

+CEREG:2,2,0000,0,7
OK

AT+CSQ
+CSQ:99,99
OK

Does anyone could be solved this issue?
Thanks,
