i think that if you have to have a parents signature you should be under 13 to have parents signature for a cell phone cause as long as the say it's okay and you have good subscription reports on magzines and etc. You shouldn't have to have parents signature i like the phone and my parents says it'as okay for me to have it but they don't want to sign something for their kids specially if you have a f on your report card! yeah well i have hope i proved my point on this stuff! Now you ahve heard what I think about having a parents signature!
