i was thinking on a refill car phone that u refill with 100$ and u can call for when money is out you go to 24/7 and buy a new card avaiable with 100$200$and 500$
and the Other kind of phone the phone you will pay like 100 for very paytime and every call is little cheaper and the amount you call for will be add to paytime(we sAy u call for 400 and then when paytime comes you have to pay 500
and the Phone book shoud be deleted and replaced with a notepad where you can save number's(so u have to rp to get the number's)
