It seems that this phenomenon is not uncommon in the United States. There is no system identification service, so naturally there is no cellular mobile network option. My V version of iPhone5 is not that serious. It will take a long time to display the signal grid, but you can make a phone call or send a text message when it is displayed, and it will appear in ten minutes. Is yours locked or unlocked?
