Unlocked my Samsung Galaxy S7. Received my code in about 24 hours. I had been using my phone with Red Pocket on the AT&T network. I wanted to unlock it to use with Tello on the T-Mobile network. AT&T said to contact Red Pocket, Red Pocket said to contact AT&T. I was tired of the back and forth and took a chance on Cellunlocker.net and it worked!
