The Samsung SCH-U550 cell phone is an average cell phone best for users who just want a phone to talk on and basic texting features. I have this phone with Verizon Wireless service, and it works pretty well for me. I can browse the internet, I can talk to my kids and my husband, and I can text friends too. I don't use the camera feature much, simply because that's what I have a digital camera for! I use the plain jane ring tone because if it doesn't SOUND like a phone, I won't recognize it when it's ringing! I have it set to also vibrate when it rings, so that I can feel it in my pocket when I'm working. I would advise anyone to get a fully-fitted phone cover for it, otherwise the screens will get scratched up. It is supposedly capable of being used as an MP3 player, with a micro SD card, which does not come with the phone, and which I'm not that desperate to add. I listen to music on the radio in my car on my way to work and back, and that's pretty much it. It is also supposedly capable of Bluetooth, which I have only used one time, to connect to a friend's phone. It did connect, but it requires a little knowledge to use that feature easily. Problems I have had with it: Certain text and/or pix messages cause the phone to reboot, and I have had at least two messages that I could not read because the phone reboots. I don't know if this is a bug or what. It hasn't happened often enough to be much of a bother to me, as the two messages it did it on weren't of dire importance. When it is in my pocket, I hear it asking for a voice command. Must be a certain side button that accidently gets pushed. Sometimes it takes pictures of the inside of my pocket, which isn't much of a problem---I just delete them. The lock feature only locks the MP3 buttons on the front screen, not the side buttons. It has been known to completely freeze up, sort of like a Windows PC, and you have to take the battery out and then turn it back on to get it to work again. I've had this happen during various activities on the phone, setting alarms, viewing text messages, and attempting to access my account online with the phone. All in all, it is an average phone for the average user. If you are a user who wants better features, such as a nicer camera with a flash, or less hassle, please look at a different phone. If you just want a basic phone with basic features, go for it!
