Answer 1

I have searched and tried and finally this worked for me

Solution 1: - /etc/mode_switch.config and turn on the following flag:

DisableSwitching=1

• Go to following folder and create the 12d1:14fe file

  $ cd /etc/usb_modeswitch.d/ $ sudo tar -xzvf /usr/share/usb_modeswitch/configPack.tar.gz 12d1:14fe

• Edit 12d1:14fe file and add following lines and save it

  DefaultVendor=0x12d1 DefaultProduct=0x14fe

  TargetVendor=0x12d1 TargetProduct=0x1506

  MessageContent="55534243123456780000000000000011062000000100000000000000000000"

If you remove the USB dongle and reconnect it. You have to run following command to bring it back in modem mode

sudo usb_modeswitch -c /etc/usb_modeswitch.d/12d1\:14fe

---

To auto detect the USB dongle as modem when it is connected then set following rule

sudo touch /etc/udev/rules.d/huawei_e3331.rules

Then create add following rules to file and save it

ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="14fe", RUN+="/usr/sbin/usb_modeswitch -v 0x12d1 -p 0x14fe -V 0x12d1 -P 0x1506 -M '55534243123456780000000000000011062000000100000000000000000000'"

Answer 2

First of all, make sure that your mobile card has 3G permission, that is, 186 mobile phone number, and other 2G mobile phone numbers can also have 3G permission;

Anyway, it is the Unicom card of Waupaca brand;

Second, isn't there a PC Suite in the software of connecting the mobile phone to the computer? In the middle of the software installation, you will be asked if you want to install the driver, which must be confirmed. After that, if you uninstall the software, you can version it, but you can't uninstall the driver;

Connect the phone cable to the USB port of the computer. There will be an Android adapter in the computer manager, which means the driver is installed;

When the mobile phone is connected to the computer, it can't turn on the U-disk mode;

Run daily up for Android on the computer... Just click Connect right
