AT&T refused to unlock my Lumia 640 because I had no used long enough on their network. I found your site and it was simple and cheap. sim-unlock performed exactly as advertised. I got the code, entered it and started using my new service right away. Thank you

I did attempt to acquire an unlock code for the same phone several months ago - no luck. And the money was refunded without any additional questions. So I tried again, and this time (after a month) got a code that successfully unlocked my phone.
