prepaid cell phones

I have been looking for some prepaid cell phones. I was thinking that maybe this would be a great birthday gift for my sister since she really don’t have one and I know that she needs it. When she starts driving she was so worried and so nervous because she got lost and she didn’t have a phone to use so that she can contact her husband. Good thing my nephew was with her and he keeps telling her to calm down cause everything is ok. Can you imagine that? A 4 year old boy is the one who told his mother to calm down cause everything is just fine lol! But anyway back to phone. I found one already that I like. Maybe my sister will appreciate it if im going to give her a phone on her birthday.
