My account is deactivate, but i don't know why my account is temporary deactivate. I send email to customers support but thay naver answer me. I make a order for samsung galaxy s4 asia network unlock code. 2days already pass. Still not yet send me any email. Do not trust fastGSM .

fastGSM? I'll say slowGSM or worstCustServiceGSM. I buyed a unlock by usb ($15) for a galaxy s3 i9300. I did all steps and the program says unlocked successfully. Good, I trusted what the program said, it's a machine not a human, so because at the moment I didn't have another sim card to test I leave it like that. Then because I was happy I unlock a HTC HD7 via IMEI ($7.49). That one was tested and worked. Then I finally change from carrier and when I put the new sim It asked me for a unlock code. What!? I contacted them Jan 27, and they responded 29 asking for a logfile, then I give them the same day what they asked and then they responded Jan 30
"Hello,
Your ticket has been escalated to a higher level of support. The support
staff is currently working to resolve this issue. Please be advised
that it may take some time."
WHAT? more time? I asked them an estimated time, and then they stop answering.
I opened a case with Paypal and then download an app from GooglePlay (UnlockUnit) and paid them $25 for unlock IMEI. It worked!
Today Feb 3 they wrote:
"it seems like hard locked unit. I can not help. Refund done."
Yeah... right. So finally after a week I have my money back.
Conclusion, they are not scam but one of the worst customer service I did have to work with.
