Summary: I bought three of these - some here and one on E-Bay as the ones in Amazon kept rising in price. They work with T-Mobile and are easy to set up. But I will tell you if you kid is expecting an iPhone - this is not it. It is a good phone for texting and calling. You can even put music and videos on it. However many of the songs I placed on them would not work or play - and no the where not license protected songs.
Summary: It's not a smartphone and it doesn't cost like a smartphone. Bought it because I liked my prev gravity phone, which died of old age. This one has a bigger screen and some small keyboard changes I'm still getting used to - reason for one star downgrade. From what I've seen, it's the only option on the market that is not a smartphone, but has a keyboard that is easy to use, which is what I was looking for.
Summary: Although the phone that I purchased had previously experienced water damage (as evidenced by the pink square under the battery), the phone is working very, very well. I am really surprised at how well the phone is working. I brought the Samsung SGH T479 Gravity 3 to replace the old one that I had because it stopped working properly. I really do like the one that I recently purchased to replace the old one.
