UnlockCode4U.com Reviews 

I have received my code in about 15 minutes, initially it didn't work, so I contacted the unlockcode4u support team, which has been very responsive and patience in guiding me to the solution of my issue, just for the records you need to revert to your stock rom if you have changed it.

The guy in the chat answered all my questions. I received my unlock code witin 2 hours and the first attempt worked. :)))

I got my galaxy S3 unlocked in 13 hours with no problems. I would recommend them.

The code worked on the first attempt. No issues at all.

The website is very clear and gives good information under what circumstances they can and, importantly, can't help - very transparent. There are clear instructions for checking if you have an eligible handset before purchase and then step-by-step for unlocking your handset once a code is received. This is the second time I have used this website and on both occasions I received my code well within the advertised timeframe. Would recommend to anyone.

Excellent service, everything occured exactly as described and the code worked first time with no problems whatsoever. Saved me having to bin my eldest sons phone as we wanted to swap networks.

Great Service! My phone was unlocked in just a few hours and the process was very simple. Recommended. Many thanks!!!

A friend gave me a Samsung galaxy S4. He was done with his contract to t-mobile and the phone was paid for. When he asked t-mobile for the unlock code all they did was stall by saying they had to contact samsung and then they said they would expedite the code, which neither happened. I would never use t-mobile.
I wanted to thank unlockcode4u, I now have a working Samsung galaxy S4. Within a day I received the code.

It actually works and worked on the 1st try. Highly recommended.

I couldn't belive i got Unlocking Code within 7-8 minutes.
I highly recommend UnlockCode4U. com to everyone and enyone
Thank you UnlockCode4U.com Again

I was quite skeptical of this service as one would be with these "phone unlock" sites, since the internet seems to be inundated with sites like this that are clearly scam, but I decided to take the dive and purchase an unlock key for a Samsung Galaxy S4 that I received from my girlfriend's mother since my own phone broke.
And I was not disappointed. The code arrived the next day and certainly looked legit since it matched the Samsung network lock key specifications. Initially there were some complications but this seemed to do with the fact that I was messing around with custom roms thinking that flashing a new rom would remove the network lock, but once I restored the stock rom and followed the instructions on the UnlockCode4U website, it worked! I was pleasantly surprised, but at the same time, the emphasis on customer satisfaction that UnlockCode4U exhibits did continue to build confidence and trust in the service they provide.

TL;DR: A perfectly legit service, very helpful with a strong emphasis on customer satisfaction. Highly recommended for your next phone unlocking venture!

I got my code in about 8 hrs (they said up to 24 hrs)
The instructions were quite straight forward and the unlock code worked at the first attempt.
Very Happy customer!!!!!

Was very satisfied unlock worked sucessfully on the first try; had to look at all the numbers and letters 3 to 4 times to make sure it was entered properly. Instructions very clear and since this device was an android pad, following instructions exactly the prompts came up, did my things and now unlocked from the 2 t's.

Great service have used this site to unlock three phones code came back really quick.

I could't unlock the phone at the beginning, but immediately they answered my e-mail explaining the process I needed to follow and then it worked smoothly. Highly recommended!

Excellent service and a great price too

I tried several of the other Cell Phone Unlock services. They could not find my code. Finally I came across UnlockCode4U.com. Took about a week. Entered code and it worked. And it cost less then the other services.

Yep, it worked a charm :) Used the 8 digit code and it worked straight away! Niceeeeeeeeeeeee oneeeeeeeeeeeeeeeee bruvor!!

My Samsung Galaxy S3 phone was with a difference because I tried the format I got from some of the sources on line but itdid not unlock my phone.
This service was exceptionally good, and the unlock information was on point. I was able to unlock my phone and is using it now.
Thank you very much

Very good service they succeeded when other companies had failed
