Verifying the phone number

Question

In my application first thing the user should do is the registration. For that i need the phone no. So the user will give their 10 digit number. Now i need to verfy the user inputed the same number which holds by the phone. How to do that ? i tried .getLine1Number() but it is returing nothing.

After pressing the register button i am calling a url which will send a verification code to the phone number was inputed by the user. Till that i am showing a alert dialog. After receiving the message only i am dismissing the dialoge box.

So the problem happens when the user give a valid number which may not their number.

PS: I need to get the response through message only.

getLine1Number function doesnt work on some GSM service providers. Instead of it you can use the serial number of the sim, it is also a unique one. — Sahil Mahajan Mj, Nov 07 '12 at 11:42

Only few service providers provide phone number via getLine1Number() method. Instead you can get a unique number for each sim using getSimSerialNumber() method.

Did you set permissions in Manifest READ_PHONE_STATE ?
Method still can return null

Returns the phone number string for line 1, for example, the MSISDN for a GSM phone. Return null if it is unavailable.
