The Lumia 520 my uncle gave to me, I inserted my sim card and saw this message
'The sim card can only be used on specific networks. Contact your customer service center for the unlock code.'
My friend told me is lock and I need the specific code to unlock it. The phone details are:
Nokia Lumia 520
Imie: 358106051083932
Anyone who can have me with it please I will be grateful.
