What is your carrier APN? wireless.twilio.com
Does your carrier need username and password? [Y/n] n
What is your device communication PORT? (ttyS0/ttyUSB3/etc.) ttyS0
Do you want to activate auto connect/reconnect service at R.Pi boot up? [Y/n] n

Could you please check if the module is powered up? If not press the POWER KEY for about 2 sec.

When powered up you can see the STATUS LED on and NETLIGHT LED blinking.

Oh, thanks.
That seemed to have gotten me a bit further, but now it gets stuck here:

First, remove following lines from /etc/chatscripts/chat-connect

OK AT+QCFG=“band”,F,400A0E189F,A0E189F,1

OK AT+QCFG=“nwscanseq”,02,1

OK AT+QCFG=“nwscanmode”,3,1

OK AT+QCFG=“iotopmode”,0,1

Then try sudo pon again.

I encounter the same issue. Event the following lines is removed, it doesn’t help. Any idea?

OK AT+QCFG=“band”,F,400A0E189F,A0E189F,1
OK AT+QCFG=“nwscanseq”,02,1
OK AT+QCFG=“nwscanmode”,3,1
