Summary: I just received it a few days back. It powers up and accepts a sim card and connects to my service PureTalk. Only problem so far is that this unlocked phone comes with the ATT logo and a lot of ATT widgets that will not work and have to be deleted. So far, a few test calls have gone through w/o problem. I plan to get back here and rate 'ease of use' and 'quality' at a later time.
