Show my number when I make phone calls

Hi! I need help to make my number visible when I call other people. I can’t find the right installation, does anybody know how to do this? It now says “hidden number” (in Swedish) when I call someone. Thanks!

From the “Phone” app tap the settings button (lower left, next to the “home button”) and then the “Settings” option from the ensuing menu.

You find yourself in the “Call Settings” menu and from there choose “Voice Call” and then “Additional Settings”.

Finally go to “Caller ID” and you’ll be able to choose whether you want to always hide or always show your number, or just use the network’s default.
