This question has been asked and answered on SO a number of times. The phone number is (possibly) stored on the SIM-card and you can get it with TelephonyManager.getLine1Number() however, it is not reliable. Some SIM cards don't have the phone number on them (in which case you will get null ) and if the user changes his phone number without swapping his SIM card then you will get his old phone number.
