A little unsure when I made my order as there are plenty of mixed reviews out there - however there was no need to worry, within 24 hours the code arrived and worked as advertised. The code took longer than the headline time advertised on the website to arrive but the instructions were clear and my HTC M8 was unlocked in minutes.

I can not say that the refund was not refunded, that was done with in ten minutes.Koodoos on the great customer service. I was on the other hand disappointed to find out just like other unlock websites, they are not able to unlock my htc 8x. I keep getting the phone is to new, they changed a IMEI, all kind of bs what it sounds like to me, but then again i do not know your system or procedures.. I did on the other hand find it strange that I got the phone from ebay seller pittsburghshop ( as for a lot of his reviews he has a habit of selling bad phones) but he tried to make me got to this website & freeunlocks.com to get the phone unlocked, me to be a dummy i did it any ways, and still no unlocked phone when it was advertised as new and unlocked. well atleast i got my cash back from you guys, but the ebay story to still to conclude its self.

I'm currently traveling across Europe for a few weeks and forgot to unlock my T-Mobile HTC One (2013 edition) before I left. Found the site through Google and was able to get my unlock code in about 25 minutes. Chose this site over others since they seemed to be focused exclusively on HTC unlock codes and because the y use PayPal.

Ordered an unlock code for my Nokia Lumia 520 which simply did not work. In fact, it had no hope of working because it wasn't even the correct number of digits! The 100% Money Back Guarantee isn't worth a dime because they don't reply to their emails; I had to get my money back from my credit card provider. If you would like to try contacting the compant by phone.

They take your money and say that they cant find it in the data base, but if you send more money, there is a 99% chance they can find it there. 

Sent 5 emails requesting help and none were answered. No way to contact them. Save your money try someone else.

I purchased a sim unlock for HTC with the express condition that there would be a full refund if they did not unlock the phone. Of course, they could not unlock the phone and now they have not processed my refund and they do not respond to my emails. I simply receive an automated response saying they are very busy...... I am sure they are busy. Attending to peoples complaints I would definitely not recommend them to anyone. Steer Clear of this company

I placed an express order paying $14.95 on March 4th, 2013 with HTCSimUnlock.com and still today March 17th haven't received anything from them. I have requested a refund twice and have also received no reply, no unlock code and no refund. There is no way to get a hold of the company. Emails to them get an automated response and you can never get any other response from them. I warning you ahead of time DON'T USE THEM!!!!

THOSE THIEVES SHOULD BE ARRESTED AND PUT BEHIND BARS FOR FRAUD! i ORDERED THE CODE FROM THEM FOR AN HTC VIVID PHONE. THEY SENT ME THE CODE WITHIN AN HOUR OR SO BUT IT DIDN'T WORK. WHEN I EMAILED THEM ABOUT THE ISSUE, THERE WAS NO REPLY. I'M ABOUT TO SUE THEM.I'LL MOVE HEAVEN AND EARTH TO GET TO THEM! NO REFUND, NO CODE!

My local phone shop tried for 2 days to unlock my Desire S and failed and worse still lost all my settings in the process! This firm provided a code in minutes and it worked first time and what's more they were cheaper. I had my phone working on a new network in about 30 minutes, order to first phone call. peterg

I ordered an unlock code for my "My Touch 3G" and when i entered the unlock code, it kept giving me an error that it's wrong. I contacted htcsimunlock customer support asking for help, but they never replied nor gave me a refund. These guys are some con artist and i highly recommend you do not use their service at all
