Read the Manual

This is about as basic as a cell phone tip as it comes. When you purchase a new cell phone, take a few minutes and browse the manual, no matter how comfortable you are with cell phones.

Just about every cell phone is different. Configuration features can be buried underneath many levels of menus. Your cell phone customer service representative may not know, or forget to tell you, about all your cell phone's features. 

Reading your cell phone manual may save you money. Some cell phones will not actually say "Roaming" or "Roaming Mode" when you leave your network; instead, they just may show a small icon on the screen. Knowing what this icon means can save you from making a very costly phone call.

Only by browsing your cell phone manual can you truly learn the capabilities your cell phone has to offer.
