We got a secondhand Samsung S6 phone for my son to use, but it was locked with a different provider. I'm not overly knowledgeable with cell phones, so I looked up a youtube video on how to unlock a cell phone. The youtube video gave a link for Cellunlocker.net. I was a little skeptical, as there are mixed reviews, but thought we would try it anyway since the price was good. We gave the information that was needed, got a confirmation email within 30 minutes, and waited for our code to arrive by email. We ordered on a Monday morning, and had the code by Wednesday evening, put the code into the phone, and it worked! I would definitely use this service again, and would recommend it to anyone.
