Just bought one, Still trying to learn how to use all features, bought it unlocked, put usim card in, and after a while got inavtive Usim message, took card out and put back into Nokia 3220 classic, works perfectly, Will post more when I have worked out the LG KC910.

I tried the USIM again today, and it works. The phone is getting easier to use, the instruction booklet is not set out well, hard to find what you need to know when you are trying to do something, it is better to just play, and you soon learn easy ways to do things, Iam impressed with this phone, I have played with the IPhone, this isn't quite as easy to use, but is still good. I think it was a worthwhile purchase, works well.

Getting better with use, much happier with phone now.
