The TelephonyManager.getLine1Number() works on GSM phones, but not CDMA phones. Is it possible to get the phone number of a CDMA phone through android API calls at all? thanks
I've successfully used the following on a Motorola Droid and HTC EVO 4G which are both CDMA.
TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String phoneNumber = telephonyManager.getLine1Number();
