i have that plan with a samsung galaxy s2. i've only had it a short while and have yet to determine if the phone is defective... it seems to turn itself off at the most inconvenient times. i just haven't found the time to contact them. however, i have found that simple matters are easy to resolve with live chat. if they can't help, they give you a 'code' to call customer service. the phone service itself has been great. i had sprint i phone and the straight talk phone service is much better here where i live. my daughter lives a few counties away and she's had hers a long time and just loves it. we are both on automatic billing with a credit card. easy peasy
