We have net10 phones.
NET10 | Prepaid Cell Phone. You can buy the phones through their website, but you can also find them at discount stores like Kmart and Walmart. When you buy the phone, you usually get 300 minutes with the price. We buy 300-minute cards/2-months for $31.80 (with tax), and I program reminders into my e-mail so a window pops up to remind me to renew. They have lesser cards you can buy on line at the website, but you can also find cards at Weis/Mr. Z's and other stores. Our phones came with nice features: Camera, text messaging, some international calling available (depends on the country and uses more minutes for those obviously), calculator, voice mail, etc. If you let the time expire, you have to do something extra to get it going again; I can't remember what it is. Minutes do stack, so we use mine for all our long distance calling plus to carry in my purse for traveling.
