Do you know if you can help me how to do it, I really apriciate.
- FastGSM - 2013-05-21T15:19:41
Hello, hardlocked phones are not supported, sorry. You can see that in our detailed instructions. If it's not possible to enter the unlock code, it's not possible to unlock the phone, unfortunately.
- Alan - 2013-08-04T23:31:55
You should try using the *#0011# number... google it, if its from telcel mexico then it should be the I9500 so you can do it by this method

can this unlock sph-l720?
- FastGSM - 2013-05-30T09:14:22
Hi, USB unlock is not possible. Maybe via unlocking codes but you have to be sure it's a GSM phone and it asks for "SIM Network Unlock PIN" when you insert a non accepted SIM card. Otherwise it would not be possible to enter the unlock code, even if you get it.
- Anthony - 2013-06-01T08:29:38

Can you guys unlock blacklisted phones?
- FastGSM - 2013-06-09T11:58:00
Hi, blacklisted phones are not supported. Even if you could unlock such phone, it will most probably not work.
- Renato - 2013-06-25T23:26:11
Don't listen to this. If you bought a blacklisted phone from the US from t-mobile or at&t that use sim card and you are planning on using it in another country the unlock will work. But won't work on any US service provider.

- JYEP - 2013-06-09T15:30:07
In order to do this unlock do I need to have the new sim card already?
- JYEP - 2013-06-09T15:50:39
What im saying is that, im about to get the phone, still just waiting for this issue of unlocking to be adressed first. But I plan on using it on carier for a couple of months before I need it unlocked. I wont get the new simcard until I need to use the phone already, Im asking do I need the new sim card/what do I need to do, to get the phone to ask me for the unlock code?

Can you unlock the sprint SPHL720BKK with this method?
- FastGSM - 2013-06-14T07:17:17
Hi, I'm afraid it's not possible, that's most probably a CDMA model. Samsung Galaxy S4 can be unlocked only if you see "SIM Network Unlock PIN" message on your screen when you power on the phone with a different network SIM card.

i was able to get "enter control key" popup upon running a command in terminal emulator.
- FastGSM - 2013-07-31T06:48:19
Hi, well the service unlocks "SIM Network Unlock PIN" or "Enter Network Lock Control Key" message when you insert a different network SIM card. If that's the case, you can use the "Samsung Unlock via IMEI - USA Carriers" service. Otherwise I'm afraid the unlocking is not possible.
- Yoshi777 - 2013-08-03T01:36:07

i have a samsung SPH-L720 ( usa sprint ) will this unlock work for me
- FastGSM - 2013-08-22T07:47:53
Hi, Sprint models cannot be unlocked, sorry. You can see on this page what unlocking is for: it removes SIM Network Unlock PIN or Enter Network Lock Control Key message. CDMA phones don't show such screen and cannot be unlocked.
- joyce - 2013-08-22T05:24:26
i have a samsung galaxy s4 from t-mobile usa and they have sent me the unlock code already. but after inserting 4 sim cards from other carrier, restarting or even doing "restore factory setting" still my phone is not asking me for the unlock code. could you help me unlock my phone?
- FastGSM - 2013-08-22T07:49:54
Hi, if your phone is not asking for an unlock code, then it's not network locked, sorry. If it doesn't work, there's some other kind of problem.
- Abraham - 2013-08-24T19:45:55

Yes I can. . Dont tell me no cause like I say I have 1 s3 connected to t mobile, this is not my first Verizon phone unlock. . I can show you. If you say no ok... then but I have my s3 whit t mmobile
- FastGSM - 2013-08-27T14:37:21
Hi, as you can read on this page, this service removes "SIM Network Unlock PIN" or "Enter Network Lock Control Key" message. If you see such message in your phone, then it can be unlocked. But I'm quite sure you don't get this message on Verizon model.
- Eli - 2013-08-27T02:46:47
I wouldn't trust this site. Apparently they don't understand that the Sprint (USA version at least) does in fact have a SIM card slot.
- FastGSM - 2013-08-27T14:33:04
Yes, even CDMA phones can have a SIM card slot but only for roaming purposes (if it's not a dual mode phone). Anyway, the description of our service says clearly that this service removes "SIM Network Unlock PIN" or "Enter Network Lock Control Key" message and you won't get the if you use a different network SIM card in Sprint phone. If you would, such phone would be possible to unlock.
- Elizabeth De Guerrero - 2013-08-27T20:06:37

- FastGSM - 2013-09-05T07:06:17
Hello, if the phone is unlocked, then your problem is no longer related to unlocking. Maybe you just need to change the network settings in your phone to automatic. Your phone’s hardware may also not be compatible with the network type of your new provider, or your phone may be blacklisted, or there may be a problem with the SIM card or the network coverage in your area.

- FastGSM - 2013-09-17T06:42:47
Hi, please read carefully description of our services on this page. With the "Network code" service, you will receive just the AT&T network code, with the "Unlock Code" service, you will receive all available codes for your phone from the Samsung factory database.

Hi, unfortunately MF3 baseband is not currently supported. It would be possible to unlock the phone via unlocking codes, but it depends on what country it's locked to. Please read details about the IMEI service on this page.

I even not sure if my phone is real or fake specially I bought it online and two of the IMEI numbers I found are not supported by Samsung Canada where I live.
I appreciate to tell me which IMEI number is the correct one and how can I tell if my phone is real or fake if possible .

Hi, you probably purchased service by USB and you are trying to submit your IMEI in My Account, which is a different service. To use the USB service, you have to use our software. If there's a problem, it's best to send an email to email@example.com
