"i don't do the unlock gig as an income source so i was using which ever unlock that could unlock the phone fir me. now do have times where i've got 20 to 30 phones to be unlocked. your actions have impressed me in a real big way! i haven't ever done more than two without getting bad codes. shouldn't need saying yet i will. from the ecceptional service i received today i know where i'm going for all the unlocks from now on. i may just start repairing phones, tablets and mobile wifi hot spots. FastGSM! thank you for being quick. accurate and having the codes i needed. Jackie Adams"
"I've got my galaxy note 4 code In less than one hour .I just want to thank you very muchI really appreciate your service to me."
"Brilliant. Codes were delivered in 35 minutes and worked first time. Also provided was a MCK code, which I think will help if you have input the wrong code too many times - I did not need that though, and the NCK code worked straight away. Glad I chose these guys, slightly more expensive than some ebay sellers but I wanted hassle-free and I got it."
"had a few issues with the payment system and credits as apposed to a more direct system. I sent a query e-mail and was promptly responded to and my problem resolved.."
"Amazing!!! Thank you! I tried elsewhere and paid more with a delay in response and still no luck.With these guys I had a my phone sorted within half an hour and fantastic price!! Thanks again, AWESOME!!!"
"All went well, fast service through USB, no problem whatsoever, surely recommend it!!"
"Success !! At first the codes did not work on my Samsung Galaxy S3 acquired in the UK, Wrote to FastGSM and got new instructions for unlocking, support was fast and corteus, the final receipe (hard reset + MCK code + RGCK code) did in fact unlock my phone, thanks FastGSM !!"
"Don't work for me. It apears "unable to unlock SIM service provider""
"I just unlocked my S7560MXXXX phone at FastGSM.com via usb, and it is the best price around"
"i was a bit skeptical about this but after figuring a few things out i did it really not that hard and if u do need help they will respond im very very happy with my purchase :) ty so much 15$ beats paying 20+ for someone else to do it"
"J'ai tenté FastGSM sans vraiment y croire, quitte à perdre 23,50€ pour mon Samsung Wave Y GT-S5380 qui était en mode Freeze après plusieurs tentatives infructueuses de désimlockage. Et bien je suis plus que surpris de l'efficacité et la rapidité d'éxecution. Ca a fonctionné du premier coup dès réception des Unlocks Codes.Je recommande."
"Very good service, they unlocked my Telcel samsung S4 that was just impossible to do for others. I've saved about 500 usd since i was considering to change my phone. "
"I tried another service that uses the IMEI method for $35, but it did not work. So when I found fastGSM, I first emailed them and asked if they can unlock my Japanese phone. These guys stated that they have another method available that should work. I was skeptical but decided to give it a try because I had no other choice. After a few email messages traded back and forth with the support guy, I finally did it! Thank you so much for your help."
