I need help on info. regarding "pay as u go" phones......i want the cheapest one, as I am "rationing" on my choice of cell phone use. As well, it'll be my first time buying such a phone, as I normally go on contracts. Anyways, I also have another question: say I use the phone for 2 months and after that there're no more minutes left......how long can I not use the phone for it to be deactivated?
