Huawei EC325

Preamble

I purchased a Huawei EC325 in Din Daeng market for 10 baht. This is what should come in the box:

Drivers

I plugged the device in the my PC. However, Windows 7 would not install all of the drivers:

HuaweiFailedInstall

This left Device Manager looking like this:

The Huawei support site did not appear to offer the drivers. Other searches only showed spurious driver.com type links. After further searching, I found the page, Huawei EC325 Data Card Drivers for Windows 7 64-Bit, which had the driver, https://app.box.com/shared/cs0xernjnq. When unzipped the contents are as follows:

DriversHuawei

However, these drivers did not seem to be recognised by the Device Manager, possibly because I have a 32-bit version of Windows 7 and the drivers are 64 bit.

Likewise, Download drivers for your phone’s USB data cable. Free! offered similar, but not the same, the same drivers:

These are the drivers (ewusbmdm.sys) for Huawei EC321 and EC325. They come from the “Huawei Mobile Connect” package.
There is no setup file for them. Please extract them to your hard drive and select them when you are prompted for the location of the driver.

I had a bit more success with these drivers, and the driver was successfully installed for the first and second unknown device:

Manuals

Equally difficult to locate was a PDF of the manual, again, only links to dodgy manualslib.com type sites were readily available. Eventually I ended up getting the manual from the manualslib.com site, Huawei EC325 User Manual. I have included it here also:

USER GUIDE – EC325

There is also an installation manual, Huawei EC-325 Installation Manual:

INSTALLATION – EC325

These instructions, Create a Dial-Up Networking connection on Windows 7,which are linked to from the first link above, proved useful to set up the dial-up network.

EC325 Manager GUI

However, the Huawei Mobile Connect package still proved to be elusive. This dubious looking site purports to be offering the software, but it seems to be unlocking software: Download USB Modems Software Files – EC325

More dodgy looking download sites, which I have not tried:

The software also appears to be known as Mobile Partner. Searching for that, found this site, which seems a bit more reliable, Mobile Partner DashBoard for Huawei USB Modem, and has multiple versions for both Mac (v.15) and Windows (v.16 and v.21). I downloaded the OS X version and the pkg installer seems genuine.

This is as far as I have got so far…
