We LOVE Net10. Minutes are NEVER mroe than 10 cents each. You can get 750 minutes for $25 per month. They don't roll over is the only drawback. As long as he uses more than 250 per month it is an awesoem deal. Unlimited is $50 per month. Texts are 1/2 min to get and to receive. Internet usage is charged in units per minute, though I don't know what as I don't go online.
husband has their touch phone (LG800G - sells for $50, no contract) and loves it (I HATE it but I hate touch phones altogether). Jess has the LG500G - sells for $29.99 and loves it. I have the LG 900G (39.99)and it is the best phone I have ever had. Very easy to use, good battery life, good quality pics for a phone, etc.... All of these are mp3 players too, you just put the songs/whatever on a microsd card. They also all use a microUSB cable for data and battery charging, which is great in the car. I actually have the miniUSB cable and use an adaptor with the phones to charge, etc.... Makes it very easy and the adaptor was $1 from ebay.
CVS will have the lg900G (my phone, regular $40) for $19.99 in their Black Friday ad. I think it even starts on Thanksgiving - and that is half off. These phones are very useful and we haven't had any problems loading apps of any kind. With the 750 minute plan for each of the phones it is still way less than HALF of teh family plan we had, esp once the taxes, fees, etc... were put on.
