I recently bought an S20 Ultra from AT&T and travel out of the country a lot. Since the phone is financed, AT&T requires that you have the phone at least 60 days and also paid off before they will unlock it. I searched Google and found this website and immediately investigated the reviews to see if it was legit. After a few hours of research, I decided to give it a try and tbh, I did not think it would work considering how new the phone is and that I am a brand new AT&T customer. Well to my surprise, less than 48 hours later, I received an email with the unlock code. Again, I thought it was not going to work but gave it a try. I changed the SIM in the phone to a SIM from Mexico and entered the code when I was prompted...it worked! I now have a carrier-unlocked phone.
Pros and Cons:
Bottom Line: Yes, I would recommend this to a friend
