Why does my mobile provider only show in the topbar on the lock screen? How can I get it to show on the topbar when unlocked?
Also in the drop down menu with the icons for some often used settings I see "no sim card", what is this for? I thought maybe as I can't see the provider in the topbar that there was a problem with the sim card, but I without wifi I was able to call someone.
When I look at the sim "settings->sim cards" there is a telephone number on my sim card, but it is not mine (the card was new to replace my old one). Is it ok to update this number?
