Hi My new Galaxy note 2 dont want connect to mobile network after one day use. I did some settings to solve the problem: 1. sim menu application/Roaming Services/Select Mode/Manual/National 2 .Settings/More settings/Mobile network/Network operators/my operator after i choosing operator name, it show "Registering on my_operator" and holding few minutes. after that it show error message "Unable to connect. Try later" I switched sim card with another carrier, but it's the same thing. what the problem?
