The mobile data icon missing on the notification bar is not a bug or something wrong with your phone. It has been intentionally removed from the notification bar of some devices by there manufactures resulting in the mobile data icon disappear from the notification bar (Don't know the exact reason for that). This situation is common on a lot of recently released phones especially Samsung phones such as S6, S7, S8, S9, Note 5, Note 6, Note 7, etc.
