Learning to use this phone was a snap.It didn't come with a SIM card, but if you have an existing phone, made in the last couple years, you really don't need a new one.All I had to do was stick my SIM card into the phone, charge it up and I was good to go.My favorite feature so far is that it has Chess on it.Pros:Polyphonic speaker (means you can download and use pretty much any ring tone you want)Free Chess Game built inEasy one touch silent mode.Games (all are Java):BubbleSmile - rotate groups of 3 bubbles to form diagonals of the same colorFun2Link - Pipe Game (link one pipe to another to reach the goalMobileChessUltimate Golf ChallengeCons:Takes a bit long to come out of key lock mode.Ring volume is a bit lower than I would like, but you can get ring tones that are louderWhen I set the alert to be "Vibration+Melody" it worked for about a week and then stopped playing the melody, it would only vibrate, so I set it back to Melody only, though I could have done something wrong (but I have no clue what that might be).
