My Motorola C139 with Net10 crashed on me. I called Net10 and they promptly sent me out a new phone, except they sent me this flip phone (V171). I liked my candy bar phone and didn't want this flip piece of junk. I was happy with Net10 service up to the point of my old phone failing, and then things quickly went downhill. Net10 would not transfer my number to the replacement phone, even though I had minutes available on the old phone.I gave my wife the V171 to use and took back from her our Cingular phone, which works awesome with no problems. She had problems all the time with the V171. She had to always type in the area codes for all numbers dialed, even the local numbers. She also had problems trying to dial a number and the phone would not dial after pressing all the numbers in the phone and hitting send. In my opinion, the V171 is completely worthless.Overall, I am a very dissatisfied customer. My recommendation is to stay away from this phone and this service. Go shop Cingular for all the great deals they have!
