getLine1Number() usually returns a value off of the SIM card. Sometimes
this is the correct phone number. Sometimes it is an invalid value.
Sometimes it is the wrong phone number -- on my personal phone, it
returns the phone's original number, before an existing mobile number
was ported over.

I am not aware of another option, however. Even on the Settings screen,
my personal phone reports the wrong number, so I have no evidence that
there is a better solution hidden somewhere inside Android.

Sorry!
