I had some trouble with mine and they had me do an update, much like the update I had to do when I was with Verizon. Verizon's update was
*228 - I can't remember, since I only did it once but I want to say that Straight talk update was *2281. Don't take my word for it, call their tech support in the morning - like 7am. and ask how to update your phone. I think it's *2281 though. you'll want to do it with option 1 and after that finishes you'll want to do it all over again and choose option 2. It really does work, just not sure about the number to dial
I switched to Straighttalk three months ago. I have had trouble with my Samsung phone shutting off by itself. After several calls they did agree to replace the phone. Only problem is they won't send a phone until they get mine. They say it takes about a week. How am I supposed to go without a phone for a week? The other problem is I can't transfer all the contacts to the new phone if I don't have them both.
I did a little research before switching and didn't find a lot of information about Straighttalk. If anyone is wondering, the customer service is no good! It sounds like the customer service is based in a foreign country.
