Flashing the firmware of this device doesn't change the USB Mass Storage memory used for the operator's software, therefore connection settings (such as APN) will be retained.Updating the modem's Dashboard does not remove or affect the network-lock (that may be in effect with modems purchased subsidized from a service provider) that prevents you from using the modem with any service provider.However updating the modem's firmware may remove this network-unlock or even the opposite, turn a network-unlock free modem into an unlocked one.Launched on 21 June 2006, the device is used for wireless Internet access using 3.5G, 3G, or 2G mobile telephony networks.It supports UMTS (including HSDPA), EDGE, GPRS and GSM.Wikipedia is a registered trademark of the Wikimedia Foundation, Inc., a non-profit organization.

Recommended: For updating all Huawei drivers, use Driver Assist.

There is also a way to do this, open the modem, remove the small internal antenna, and solder a UMTS-antenna cable onto the board.

The warranty will be invalidated, but it can be a cheap and functional way to connect an external antenna.

It is possible to remove the operator branding by flashing the device with Huawei's Mobile Partner software.

Huawei does not publicly release firmware updates for its devices, only Dashboard updates.
