As far as I know it does that automatically if you have caller ID activated on the sim card

You cannot add the number. It is supposed to be automatic, usually dependent on the network.

Hi.

That edit button is meant to edit the phone's name only.

You can't add the phone number because that phone number is read from the SIM card.

If the SIM card doesn't contain the phone number, it will be displayed as Unknown, just like in the screenshot you attached.
