My dad has the v262 and the reception is good but not anywhere near as good as the 6255i's RF. Also, the phone has like no features and its not much more to get another 6255i. I wouldn't waste my money since I can make 90% more calls then he can with his v262 since he can never get a signal. Where I happen to live I have tested every MetroPCS phone and all phones have problems getting a signal. The 6255i is almost 5x better at getting a signal in low signal spots then ANY OTHER metropcs phone. You can also keep a signal inside malls and stores which the other phones can't.
a670 is made quite well but it doesn't even have a speakerphone! Its almost the same price as the 6255i and the a670 has NO FEATURES whatsoever!? RF on the a670 is ok but no where near as good as the 6255i.
