getLine1Number return null but not always

Question

I use the TelephonyManager to get the phone number, in the SDK all works perfectly, on some devices like my hero with 1.5 it returns null, on the tattoo with 1.6 it works but on some other tattoos it returns null.
Is there any other way to get the phone number?

Are you using the same SIM card in your phones? Maybe try to swap them and see if this is a device problem or a SIM card problem as mernen suggests. — Janusz, Mar 15 '10 at 08:30

As far as I know, the phone number returned is whatever is stored on the SIM card's MSISDN, which isn't filled by some operators. (Worse still, according to some reports, the number might actually be incorrect!)

Unfortunately, I don't know of any other method, either.

I searched a lot for this problem and didn't find any solution. There is a solution of reading SMS or sending SMS from some server.

The solution is to put the SIM card in a dumb phone (or any Blackberry pre-2009) and the MSISDN will be set. I think with Blackberries you can manually set them.

Try dial ##000000 with the radio off and edit the first line in the menu that shows up on the Blackberry.
