Mobile Broadband
Purpose
The Mobile Broadband API is used to implement connectivity to cellular networks. Applications should not communicate with such mobile broadband devices directly. Instead, they must use the Mobile Broadband API.
Developer audience
The Mobile Broadband API is designed for C++ developers.
There's also an interface for .NET developers using C#.
The Mobile Broadband API can be used by third-party applications that need to control and manage mobile broadband interfaces.
Run-time requirements
Mobile Broadband support begins with Windows 7.
