Hello guys. I buyed a Nokia n900 from someone and it worked well for a month!! But now it started showing me the icon of the Sim with the Red slash I read about this problem in the internet, in your forum, tried all the things that i've read, but none of those worked Also, not to forget to mention, I am from Kosovo, but I study in Macedonia and when this problem appeared, i put some paper between the battery and the sim card slot and put into the slot the number from Macedonia (T-Mobile). It worked well 1 day, 2 days, 3 days.. but when I've put the number from Kosovo, the problem appears again. Then I put again the Macedonian number, it worked again very well. I came from Macedonia, and went to change the Sim Card, to take a new one. They gave me a new Sim Card, but now, it shows me the problem with my two numbers, even with the Macedonian number What should I do?? Has someone found the solution for this damn Problem ??? Can someone please help me ?
