How to get location using SIM in Windows 8 App in C#?

Hi,

I want to know how to get the location from SIM card in Windows 8 Store App in C#. I know Geolocation Geoposition gets the location from GPS and Wifi hotspots, but if I need to get the location from SIM service provider, how do I do it?

Please help!

Thanks in advance.
