          Hi!

          Great tutorial!

          I use Raspbian Stretch Lite and I can not get the S103-G to work with these instructions. The command cu -l / dev / ttyAMA0 crashes when I try to AT command. Ifconfig does not give ppp0.

          What have I missed?

            Hi
            have you disable the BT on Pi3

            /boot/config.txt addline

            dtoverlay=pi3-disable-bt

            and on /boot/cmdline.txt remove

            serial console than its looks like

            dwc_otg.lpm_enable=0 console=tty1 root=PARTUUID=e13fdf55-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait

            Regards

                  Now i have tried with Rasbian Jessie Lite.....no success :disappointed:

                  Do you use Jessie Lite or full?

                    @Vesa-Kauppinen I think you have missed one or more step of the turorial. I suggest you to retry the tutorial and check if an instruction fails. Do you have switch on the GPRS module?

                      @roberts_lando Hi, I've done all the steps to configure the internet connection but when I type "ifconfig" it doesn't show me the ppp0 interface. Could you please help me?

                      when I type the command "cat /var/log/syslog" It show me this messages:

                        The issue was by the incorrect comm speed with the modem. I modified the guide provided by @roberts_lando to use the proper baudrate of 9600 instead of 115200.
