Summary: I had this phone while I was living in the US and I ran it off of the T-Mobile Network and Simple mobile and it worked flawlessly. Here in Uganda Africa I have used it with the MTN and Airtel Networks without a hitch although Orange has better internet at better prices. My wife has one and I am replacing the one that I had which got damaged on a mission trip when I got caught in a severe lightning storm.
Summary: I only used this phone for a full year (I say that only because I usually upgrade every year despite how good or bad the phone is) and it was a great device when I used it (I still have it). For starters, there aren't too many portrait slider phones out there, so right from the jump you'll be unique and stand out in the crowd. The Display seems to be curved a bit, but it is rather large and the colors look so vibrant and pretty on it.
