Linux - USB Modem HUAWEI E3131 (12d1:14fe) Sending SMS

We will use Debian GNU/Linux 8.7 (jessie) and HUAWEI E3131 modem 12d1:14fe. First of all we need to install usb-modeswitch to switch from USB Storage mode to GSM modem. We also need to install smstools for sending text messages via this modem.

apt-get install usb-modeswitch smstools

To configure usb-modeswitch, open /etc/usb_modeswitch.d/12d1:14fe with your favourite editor, and paste this text:

# Huawei E3131
DefaultVendor= 0x12d1
DefaultProduct= 0x14fe
TargetVendor= 0x12d1
TargetProduct= 0x1506
MessageContent="55534243123456780000000000000011062000000100000000000000000000"

Then run:

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

Open /etc/smsd.conf, and paste this text to the end of all text, also commenting [GSM1] and all it's parameters before:

[GSM1]
device = /dev/ttyUSB0
incoming = yes
report = no
check_memory_method = 2
signal_quality_ber_ignore = yes
decode_unicode_text = yes

Start smstools:

/etc/init.d/smstools start 

Try to send sms by editing /var/spool/sms/outgoing/sms file and putting to it:

To: 8611111111
This is a text message sent by smstools!

With this config you will also be able to receive messages addressed to the telephone number of this
