📱 Huawei E1752 on Linux

10 Aug 2015

The Huawei E1752 is an ancient USB HSDPA modem which can be still used for connecting to the internet or even sending and receiving sms messages. This post is about to get it working on Raspbian/Jessie to use it as a backup internet connection and sms-remote control my home. One would expecting it to be more difficult, but it’s very easy to install or use.

So here are the steps i done:

Do not connect your usb modem yet, first you need to install the usb-modeswitch and gsm-utils package. These are both necessary for the modem to function properly and support sms.

sudo apt-get install usb-modeswitch gsm-utils

Now edit the /etc/usb_modeswitch.conf and paste the following lines:

# Huawei E1752 #
DefaultVendor= 0x12d1
DefaultProduct= 0x1446TargetVendor= 0x12d1
TargetProduct= 0x1001
MessageEndpoint= 0x01
HuaweiMode= 1


It’s time to plug in the Huawei USB Modem and it’s going to appear under /dev/ttyUSBx

Test the modem with sending an sms:

echo "SMS message" | gsmsendsms -d /dev/ttyUSB0 -b 19200 PHONE_NUMBER

There should be no output if everything went fine and the sms is going to arrive in a few seconds.

To be continued with the internet config…
