I'm having Sim Card error in my new Nokia Lumia 1020, I'm using the nano sim from the iPhone 5. When I first tried to put the sim in it was stuck, I'm not sure if it's easy to damage the sim tray in the Lumia 1020. I get the sim card error some times, but it would fix itself in a few seconds. I wondering if this is just a software issue or if it's a hardware problem. I got my phone from Best Buy so I don't want to return it if it's not necessary, I still have a week left to do that.
