Get mobile phone operator from android CallLog

is it possible to get the name of the mobile phone operator from the android CallLog? E.g. in Germany phone numbers have xxxx - xxxxxxx form.

Normally the first 4 numbers of the 开发者_StackOverflowphone number are an identifier for the mobile phone operator. But in Germany you can switch the operator, porting your mobile phone number to your new operator. So the xxxx itself is no longer a hint what operator is behind a phone number or a call.

Is it possible to get such information from the CallLog or any other log of the android phone?

No. Provider detection and routing is done at the backend - the phone just receives the phone number in the "incoming call" event.
