I myself do not care to play the straight talk game. Google it, tons of issues. Right now I have PP and have had for 3 years. Love it! I am not a huge talker. I can get by with their $80 pin which gives me 2000 minutes for use over 1 year. If I run out I just buy another pin and add it. I am never doing a monthly plan again.
My niece was about to move to ST too but I now have her on PP.
