Well, it depends what you want. If you like to text, then get it.
If you are a geek, like the reviewer guy from above, then the Galaxy series phone are alright.
I honestly don't like contracts so I don't have T-Mobile, AT&T or Verizon.
I have Cricket Wireless and I have unlimeted calling worldwide, Texts (worldwide), local calling, unlimeted Data plan, all for 55 monthly and no contracts.
