I was looking to get an old S5 unlocked to use as a spare phone and gave NetPal a try after looking at a few options on Google. My phone was locked to EE, I filled in the online form, paid with PayPal and waited for the results. The site quoted 3 to 24hrs for an EE unlock but my order took a lot longer. I emailed to ask about the delay, and was answered quickly as to the reason. All in all mine took about 5 working days but when I received the code it worked first time. But for the unexpected delay, this would have earned 5 stars as ultimately the code worked. I would use NetPal again should the need arise once more.
