How to get user location based on sim mobile network in android in c # "?

I want the user's current location (latitude and longitude) to always be used only based on Sim-based, and not using other networks (for example, Wi-Fi, mobile data, GPS and other networks, and even they are all in the " On "in mobile). Not necessarily exact location, but even approximate location.

Is it possible to get it? If any of you can explain and include the code; I have searched on google but didn't get the right answer.
