Actually, the Huawei Connection Manager software comes bundled with the Huawei mobile Internet keys and not with the mobile phones. All major Huawei cellulars should come packaged with Mobile Partner. However, in order to install Huawei Connection Manager to your computer, you need to insert the mobile Internet key in a working USB port and to open the Huawei drive from My Computer/Computer. After that, double-click Connection Manager, select Setup and follow the on-screen instructions. If you have problems, I recommend you contact Huawei Support Team using
+1 888-548-2934 phone numbers.
Also, you need to know that using Google search engine, you can find a link to download the Huawei Connection Manager software. It is free of charge and it can't be acquired from the official web page because it should come bundled with Huawei devices.
