How to get Service Provider, not the Network Name

I have an Application (Operator Widget) which Displays the Name of the Network you are currently Connected to.

The Problem is that some Providers either share their Network with others (eg. T-Mobile UK uses 3's Network in some areas) or don't have an own Ne开发者_Python百科twork and use the one of another Provider (eg. "bob" uses the Network of "A1").

The Problem is that the getNetworkOperatorName() always returns the Name of the Wireless Network (so T-Mobile Users will see 3 as their network...) which confuses Users. Android itself on the Other hand shows the Service Providers name, what is the Function to do this?

Did you try getSimOperatorName()
