sudah terdeteksi sebagai modem
tinggal konfigurasi lewat network manager, wvdial atau pppconfig
3. Supaya tidak eject manual masukan ke rules
sudo gedit /etc/udev/rules.d/78-qualcomm.rules
Copy paste baris berikut dan simpan
ATTRS{idVendor}=="05c6", ATTRS{idProduct}=="1000", RUN+="/usr/bin/eject %k"
sudo udevadm control --reload-rules
Semoga berguna
