I read the reviews on this site, Highya, and was a little hesitant to try unlocking my TMobile Samsung Galaxy Note 3 (N900T). I know that most people who leave reviews do it because they had a poor to horrible experience or they had an amazing one, so I started looking at the low scores. A lot of the reviewers, from this and other review sites, don't leave concise reviews, make ridiculous typing errors and seem like they wouldn't be able to program the time on a microwave. That's okay; some people shouldn't be messing around with unlocking their own phones, anyway.
After looking around at other providers like this and asking T-Mobile to do it, I decided to save $20 and get a code with cellunlocker.net. I know there are a few models of my phone depending on the carrier, so I made sure I used the correct one and provided my IMEI. I was given a 1-5 hour turnaround estimate. I received confirmation of my purchase at 3:19 pm and received the email with unlock code and instructions at 6:15 pm the same day. I followed the first unlock method and was immediately successful.
Bottom Line: For "true savvy" (not "wannabe savvy") individuals, this is a great way to get an unlock code when your provider refuses to give you one or is going to charge more than it'll cost here. I believe some of the negative reviews are actual experiences, as all businesses have similar issues now and then, but this can be a quick, less-expensive option for an unlock. Here's to phone freedom!
Bottom Line: Yes, I would recommend this to a friend
