Hello readers, I bought a nokia lumia 710 and upon inserting my sim card it ask for the puk code, which I immediately requested from my network service provider unfortunately the puk code didn't work. I thought it was the chip therefore I bought a replacement sim card, much to my dismay, switching sim cards was of no avail because the puk code output the message incorrect puk..... So i'm wondering if the puk code doesnt unlock my sim what are my options?? should I disregard the phone utterly.?
