drivers
Drivers will automatically be installed during installation of Mobile Partner or the Vodafone Dashboard if you have a Vodafone-branded device. However if you need drivers separately for any reason, you can either find them after installation of Mobile Partner in C:\Program Files\Mobile Partner\Driver or here:

Windows Vista: http://rapidshare.com/files/154228968/Huawei_E169_Driver_Vista.zip


activate voice calling

• download and run latest firmware/dashboard update from Huawei (http://www.huawei.com/mobileweb/en/doc/list.do?type=-1&id=4381). This update will replace Mobile Partner in the flash memory of your E169 by a version, that supports voice calling by default.
• after finishing the update unplug and replug your E169 and reinstall Mobile Partner from the modem's flash memory
• now start Mobile Partner and you should see a button named "call"

If you want to keep your existing version of Mobile Partner, you can also activate voice calling by downloading this version of PluginsConfig.xml and saving it to C:\Program Files\Mobile Partner\config while overwriting the existing version.

microSD-drive
Some versions of the E169G (e.g. the one sold by O2 Germany as "O2 Surf Stick") lack microSD-support, allthough the hardware is present beneath the housing (there is no lid, so the microSD-drive inaccessible without dismantling the device). Below you see a regular E169 with accessible and working microSD-drive:



disable/revive flashdrive
The integrated flashdrive of the E169 can be disabled by executing the following AT-command:
at^u2diag=0
Unfortunately this will also disable the microSD-drive.
To revive the flashdrive and the microSD-drive execute:
at^u2diag=255


(hidden) antenna connector (present in all E169 versions)
Please be aware, that dismantling your device will void your warranty!
The E169 does have an antenna connector, which on some versions (e.g. Vodafone's) is covered by the housing and so inaccessible. Other versions (listed in the table below) have a lid for hassle-free access to the antenna connector.

versions with lid for antenna connector	versions without lid for antenna connector
Virgina E169 (AU) 3 E169 (UK) eplus/Base Internet Stick E169 (DE)	Vodafone E169 Vodafone E169V Vodafone K3520 (DE) o2 Surf Stick (DE)

However if the lid is absent a hole can be drilled into the housing. Therefore open the housing by removing the screws next to the USB-plug and firmly pressing on the edges (where the red part is below) while carefully separating the two halves of the housing. Look at the pictures below to see where the nibs are snapped!
