turn it on
Look for it.
No
No, because voice mail only works when you have your phone switched on. Voicemail is in your phone so if it is turned off how can it work?
When it is first turned on from being off for awhile.
To charge a cell phone you will need either an outlet plug-in or car charger compatible with your particular model. The best way to fully charge a cell phone is to turn it off completely while charging. At the butt of the cell phone there should be a thin slot to plug your cell phone charger into. Plug the other end of the charger into your wall or car's cigarette lighter.
if you take your cell pone to school you should have it turned off all day especially if it has bluetooth
