I'm looking for a prepaid cell phone, a cheap one. I don't want to get a monthly bill because there are going to be periods of the year where I'm not going to use my cell phone. I don't talk a lot, but I don't talk a little. The last phone I had, I used an average of 600 minutes a month. What's a good deal and what are the details of the plan? I also want to know do prepaid phones use SIM cards? if they do can you put the card in another phone and have it work?
