Planning to buy a cell phone, so while discussing with friends I came to know about Jitterbug cell phones. But they all were really not very much conformed about its plans and services what all they know about the cell phone is it is cheap. So I want have little more information on this jitterbug cell phone. is this cell phone roaming free across the nation? What are the call charges and approximately how much will it cost to me. Does it look cool?
