"One of the best mobile providers I have used in years! Would definitely recommend it since their reception is fairly good in all areas and customer support is very caring and friendly!"
"Great service, efficient communication, very trustworthy company."
"They provide a good service despite that their webpage looks scammy. These guys are legit."
"My SM-V100T (mobile hotspot) that I ordered from Amazon.com was locked to T-Mobile. I doubted this website since it had the most rip-off kind of look. Since my choices were limited to none, I tried it anyway. IT WORKED. Can't believe I'm saying this, but it worked. The way it works:
1. First you open an account for free.
2. You need to choose the kind of service (unlock device\unlock sim)
3. Then you need to choose where it was bought from.
4. You pay accordingly (you can pay by paypal which is awesome)
5. The website adds not the service, but the amount of money that you paid for the service.
6. In your account page, in "use services" tab, you have to make sure you choose the right one (via the price you paid and the description). Then you click on "use chosen service".
7. Afterwards you just have to wait. The website said it would take up to 3 days; I waited about 7 hours tops... AND IT WORKED!

"I was having trouble at first, I was doing everything the guide said to do and nothing was happening note 3 wasn't being detected. Finally I e-mailed customer support and they ask if I had stock ROM if not then they can help me get stock firmware. Yes my note 3 was rooted with custom recovery. I have backup of my stock ROM so I flashed it back to stock. Then I tried the USB unlock again and it worked the first time. It only took seconds to unlock. I rooted the note 3 again and installed TWRP custom recovery. Phone is working like a charm with no problem"
"AT&T provided Unlock code did not work for my Samsung S6 edge (model SM-G925A). but Fastgsm unlock via USB client application worked like magic. Just follow instructions."
"I had a great communication with FastGSM who did the best to help me unlocking my Samsung Player 5."
"Hi there, just wanted to say thanks for a fantastic service.. i was a bit skeptical as other sites charged almost 3x the price, your instructions were excellent and worked first time! my S5 was locked to chile, and asked me for the unlock pin, and now its gone / sim gets a signal. Super happy -ill recommend u to anyone!!
thanks again!"
"I have to be honest I was very very wary of using this site as I had read the bad reviews and I thought well if it is a scam then it's my own fault as I read the reviews and didn't listen.
In all fairness it is a genuine website and unlocked my Samsung S5 (G900-F) which was on EE to 02 in under 10 mins (Using the USB method) all you need is a basic knowledge of a mobile and computers to do it and it was cheap it cost $14.99 which is around about £10.37 GBP unlike the shop on my local high street who wanted £25.00 to unlock this mobile.
Also don't waste your time on those survey things they don't work spend the £10.00 and get it unlocked professionally, Virus free and fast.
I would highly recommend www.fastgsm.com to anyone who wants a reliable service
Thanks so much GSM you've made me very happy on Christmas Day."
"I bought a SIM unlock via usb data cable for my Sony Xperia X10i phone for 5 USD. The procedure was a piece of cake. Now I'm happy with my "free" phone."
"Bought their unlock by USB service, didn't work at all on my phone and now they won't reply to my emails or calls to their offices in Hong Kong."
"
Great service. Had to temporarily use an old Samsung S5570 and not being up on these things I thought I’d try unlocking it this way and followed Youtube clip and paid approx £10 to unlock - very easy using USB. Would recommend - thank you."
"Needed a network unlock code for my Samsung Galaxy phone to change provider so downloaded and used Fastgsm software, within 5 minutes from start to finish the phone was unlocked. Software is very easy to use, only other requirement is a usb cable to link phone to laptop or pc."
"Hello,
I payed for Samsung Unlock by USB on fastgsm - then i followed all the steps and i unlocked my Samsung S5 - SM G900F on my computer. All is good - worked just fine, very quick, no issues.
Thank's fastgsm.com.

"I gotta admit I was skeptical of this website because when you click on people's profiles, you will see that most people have only 1 review (FastGSM).
Later I went on YouTube and saw people posting their unlock process, so I told myself this could be legit because they went on the website and did all the steps.
In fact, it is legit. People come here to post their reviews because after you unlock your phone, the websites sends you an email saying "We value your feedback. Share a success story to help us improve your experience and qualify for a service refund - one customer selected each month." which links you to this website.
Honestly, the price is right and it works. I unlocked my phone from here.
Good luck!"
