I was nervous due to lots of negative reviews and was so especially when I didn't get anything after 48 hours. Then I thought it was a really scam and sent an email that requests a refund. Few hours later I got a bunch of codes and one of them was the network unlock code which I needed for my case. I tried that code and it really worked. Now I am thinking that the most of negative reviews claiming this company is a scam came from competitors. Who else will lie here? I will use this company again future and I will recommend this company to my friends and family.
