Nokia 6010 | Phone/Device Issues and Features | Consumer forum

I put my 7-11 sim into my Nokia 6010 that I had from Rogers. For some reason it will not show the time unless the phone is in standby mode. This is a real pain because if I want to see the time at night I have to hit a button to make the phone light up, but then it comes out of standby and the time disappears. It won't display the date, either. I'm sure I have the correct settings selected in the menu. Any suggestions?
Thanks
