I have two Straight Talk phones. When everything works, it works WELL, but if there is a problem, it could potentially take days and days to have it resolved. The problem is that all of the Straight Talk representatives are in Guatemala. If you need answers to common questions such as "when does my service date end?" they have no problems answering you. But if you are having problems that they do not have a routine answer for, the language difference becomes a barrier. For the price you pay, it is definitely worth being patient with them. Here is what I strongly recommend: 1. When you first activate your phone, DO NOT register your credit card online (e.g. for automatic refill) UNTIL you have completely activated your phone and you are sure that it is working. Then go back and log in to give your credit card info. 2. If you are transferring an old phone number from a different carrier, be sure you have the correct account number (different from the cell number). This process takes a couple of days, so again, do not give credit card info until the activation is complete. Just use the air cards you buy from Walmart. I HIGHLY recommend Straight Talk. Just understand that there is a language difference and IF you need to speak with them for something "out of the ordinary" you will need plenty of patience. Just think about the money you are saving!
