LG Black vs Galaxy Ace

[wfeere]

Hello,..........I currently have the Samsung Galaxy Ace. I have had troubles since new, I'm on my 6th replacement now. Each one keeps telling me, "Unregistered Sim" the only way to get the phone to work when this happens is to remove the battery and sim card and then replace them, the phone will work great for an hour, two hours, a day? My wife has the very same phone and hers works perfect,.....go figure.

Any way, I'm fed up,.........I'm looking at the LG Black.

Is this a better pone than the Galaxy Ace?

Thanks
