"I have purchased the Galaxy Note 3 N9005 LTE in Europe and activated it with an European SIM.
Unfortunately, as opposed to Samsung's claims, it was locked to non-European SIMs (I used an Israel SIM card).
I have purchased the Unlock service from FastGSM but unfortunately they couldn't find the proper Unlock Code. Consequently', they immediately and without hesitation refunded the purchase price.
Few days later, on their initiative I have got a notice that a new service for European GN3 is available.
I have re-purchased the service and bingo, it worked and my GN3 is now Region and SIM Lock free!
The happy end is a result of at least 10 emails that were exchanged between me and Tomas from FastGSM who patiently answered all my questions.
A service at its best. "

"I just want to say that I always use this service in future because of my awesome experience unlock related issues as well as I refer all of my friend towards this software..... I"

"For LG c660H Good and fast unlocking service.

"Unlock code was obtained quickly. I am very pleased. Thank you!"

"I bought a Samsung Note 3 from AT&T and purchased this unlock code from FastGSM. It worked like a charm !! I tested it with a Vodafone Sim card that I purchased last year in New Zealand and I was able to make a call from it. I think this means it will work when I travel overseas with a foreign Sim card. Thank you so much for emancipating me from the shackles of the evil American phone carrier !!

I upgraded to the Note 3 from the Samsung Galaxy 3. AT&T said they can help me unlock my S3 because I have finished my contract but they gave me an unlock code that DOES NOT work. I called them 5 times and each time I was directed to a different customer specialist and opened a new case to "investigate" why the code did not work for me. Guess what happened ? They email me back with the SAME code that DOES NOT work 5 fxxxing time !! Can you believe how incompetent those suckers at AT&T are? Thank you FastGSM!!"

"Very good explanation about the products. Very fast and effective support. fair prices."

"I must say I'm very satisfied with their services! I had a lot of trouble trying to unlock my Xperia SO-01B by DoCoMo, but their customer service was so good that they helped me solve all of the issues quickly and efficiently. I'd recommend their services to anyone in need of unlocking phones in a cheaper and faster way!"

"i have unlock more than 10 phones for me an my family and never have a problem with the codes or the methods that fast gsm provide
i also like, that they have video instructions and every detail that you need to follow to receive want you want. i recommend totally the fast gsm service."

"Hi GUYS,

"Unlocked my AT&T Galaxy S4 with ease.
Tried the free method online, which didn't work.
Then tried buying a code on ebay, they refunded my money cause they couldn't find a code.

Had given up, but I heard a few success stores on XDA about fastgsm, I didn't want to try ordering a code again so I tried the usb method and it worked perfectly and quickly.

It was much easier than I expected too, directions where flawless."

"I tried a lot of sellers and nobody can not unlock my galaxy s4 sgh-i337m from claro pr and fastgsm.com could unlock in just 5 minutes. They are the best. Se los recomiendo a todos los que tienen claro pr. "
