Reading device phone number throws NULLPointerException

Question

I am trying to read the phone number of the device using the following code. When phone number is not available I read the subcriber id. It works in some phones and throws N

Answer 1

In order to get the phone number from the device , first you have to set your own phone number on the device, just go through :

Settings -> About Phone -> Status -> My phone Number

When you call this code:

MyPhoneNumber = tMgr.getLine1Number();

It's the stored number is actually returning.
