Siemens A60 help turning on

I have a siemens A60 I use only when traveling internationally - thus the reason for turning on agian 6 months later. When I turn on the phone - it initially asks for me to enter my PIN number (which I do not remember). Any clues how to get around this issue so I can use the phone?

You need to try the code eventhough it is not correct. And then it will ask for PUK code. Don't worry, the code should be written on the card which was attached to your sim card when you first got it. Or else call your service provider customer service. They will ask your personal details and then give the PUK code.
