Huawei E1750 3G Modem

The E1750 is a UPA (7.2Mbps Downlink and 2Mbps Uplink) modem with Plug'n'Play functionality - The Connection Manager is auto installed when the modem is connected to the computer for the first time. The E1750 supports all major operating systems including Windows Vista and Mac OSX.

The Huawei E1750 modem is found immediately by the GSM Modem Gateway in Diafaan SMS Server. The modem uses two virtual serial ports, in my case COM3 and COM9, either one can be used by Diafaan SMS Server. If you want to use Mobile Connection Manager together with Diafaan SMS Server (not advisable!) it is only possible to use the first COM port since the other one will be in use by the Mobile Connection Manager software.
