I'd like to ask a question about the icon on the top left.
I've read on a WP8 board that's a locked sim icon, but why my phone locks the simcard ? The only way I found to unlock the card is: 1- go to parameters -> phone -> switch from automatic network selection to manual and back again (the phone ask me to insert the pin and here I go) 2- turn of/on the device
Someone can tell me for what reason this happens ?
I own a Lumia 820 with the last update available.
