Title says it all ( I think ), if I look under the 'Settings - Status - Phone number' on my Samsung Galaxy S mobile phone, it says 'unknown'.

What does that mean ? Do I have to enter the number some where ? And if so, do I need it, or why should I do that ?

This is just showing whether your phone number is saved to the phone number description property on your SIM card. Some networks always program this in for you, many don't. Some phones let you write to this property, some don't, some read it, some don't.

It has nothing to do with what actual phone number is attached to that SIM card by the phone company.

It is possible to put your phone number in there, and is easier than you might think:

Go into Contacts -> [Menu] -> More -> Settings -> Own numbers -> [Menu] -> Create and type your phone number into the Number field, now Save.

Then switch your phone off and on again, and it should show the correct number (or whatever number you entered) in the status now.

unfortunately, this doesn't appear to work on the galaxy s2 –  yincrash May 24 '13 at 16:40
There is no "Own numbers" anywhere in the Contacts app, at least not on a stock Galaxy S4 Mini. –  romkyns Oct 5 '13 at 13:42

well there is no path as suggested above, there is no ''own numbers'' option in any of the contacts settings. It seems completely locked out. I am searching for a phone that will allow me to write this to the SIM card.

Technology that causes grief and trouble has failed.

@Ads what phone have you got? My answer was specific to the Samsung Galaxy S series running Samsung's TouchWiz interface and customizations, it almost certainly works differently on other phones, if you have a different phone please ask a new question specific to your phone and someone who owns one of those may be able to help you. –  GAThrawn Jan 4 '11 at 15:23

Some Android phones don't support such advanced features as "setting own phone number". In this case try set it on a different phone, preferable a dumb phone.

There is also a problem with some 2.2-Froyo code for the Galaxy S that can cause this to happen, even if your number was shown under 2.1. (This is the case for me).
