so am 18 and i got an att cell phone i have a family plan, we pay around 168 a month for 3 phones and 1000 rollover Unlimited nights & weekends my mom and dad have a motorola razor no internet no messaging. i have a blackberry i have Unlimited internet and messaging. i recently started working but in a fast food so i don't make much, but i decided to pay my part of the phone and my parents said i had to pay 90 a month ?? i don't understand why so much is this right? i checked and am getting charged 50 for Unlimited internet and messaging but i dont think i should be paying 90.. my mom says i do because her phone does not have anything. is this right? what should i be paying? is it better if i get out of the plan and get my own phone bill with att?
