This phone is terrible. I really only use it for talking and texting, and it can't even do the most basic functions. Texting is a nightmare on this phone. The T9 feature is useless, and often chooses random combinations of letters instead of words. You cannot use punctuation with the 1 button because it will freeze the phone, and even though I have gotten used to using the menu for any kind of punctuation use, if you try to delete punctuation, or pretty much half the time you delete anything in a text message, the phone freezes and deletes the message.
Talk is comparable to other sprint phones; problems with service in areas that other providers have no problem with, like in most large buildings and even just random areas with no explanation. I'm not sure if this is to do with the phone itself or sprint service.
Battery life is poor, will sometimes last a full 2 days, but will also sometimes turn off without warning and leave you stranded if you don't have the charger with you. I have taken to keeping the charger with me just in case, very annoying.
The one good thing about the phone is the simple design. It's not trying to be a crazy smart phone, but it doesn't make me feel like it was made in the 90s. If only the functioning was similar.
