You can't make it "SIM-free", it's gonna need a SIM if you want to use the device on a mobile network.
Unlocking allows using the device on other networks with other SIMs, it does not allow a device to work on a network without a SIM.

I think You didn`t understand me. I don`t want to use phone without SIM. I just want to unlock phone from one mobal carrier, so I could use another.
We say in Serbia that the phone is SIM free if it is not locked on a network. Specifically in my case, this phone is locked for MTS mobile, but I want to use VIP mobile.
I tried SGS2 sim unlock by Chainfire and did not work.

Unlock methods vary from one device to another, it can even be different on the same device with a different firmware build number/android version.
If it were me, I would just do a Google search for:
"How to SIM unlock (your model number)"
You might have to use your stock firmware build number to get more specific information. If that doesn't find anything, there probably isn't a known unlock method for your device, if there were, someone would have posted it somewhere. Other than that, you can try asking your mobile carrier to provide you with the unlock information/service.

The app GalaxSim unlock by spocky works. I did buy it from playstore. I don't know any free solution and most ask for quite some money (much more then this app anyway)

Unlock For Use In Spain

Hello, I am currently in Spain for 6 weeks for work. I contacted T-Mobile for an unlock code for my phone prior to leaving. I got a sim card today, popped it in and booted up, but my unlock code doesn't work. Does flashing roms have any effect on the unlock code working or not? Any help would be greatly appreciated. Its not easy being here without a phone.

What's happening exactly after you boot?
Because I'm also trying to use a Vibrant in Europe and I don't even get to an unlock code... it just boots as if no SIM is in, and doesn't do anything with it (it shows it's in there, but I can't choose operators, join networks etc.).

The SIM you have probably has different bands than what the phone can support. Check GSM Arena for what bands the Vibrant supports. If you are sure its supported, it's probably that the phone can't read the SIM. If it can read it, it will ask for an unlock code.
@ OP: ROM flashing does NOT affect whether a phone is locked or unlocked. The code you were given is wrong then. It could be possible that you wrote it wrong since they spell it over the phone usually. I would contact T-Mobile AGAIN and be a bit upset over getting the wrong code.
Alternatively you can use an app called Galaxy S Unlocker to unlock the phone. But try calling T-Mobile first. It's faster and easier.

What does then (exc. from finding an unlock code)?
Cause I'm stuck, GSM Arena says it's a Quad-Band phone and supports the European frequencies.
Once unlocked, nothing should affect the phone's unlocked status.
I beleive carriers and manufacturers can lock it again but I'm not sure of the procedure. For your issue, GET the correct unlock code and you are good to go.
I was going in circles with T-Mobile. Ended up buying sgs unlock off the market and was unlocked in less than a minute. The T-Mobile support staff are useless.

[Q] unlockable from network?

Hi all
I am thinking of getting rid of my Galaxy SIi to get one of these. One of the ones I have seen to buy is locked to T mobile so I was wondering if it is possible to unlock these phones as I am on vodagone. If so is it a fairly easy procedure?
Thanks
Impossible at the moment. XPS is a mighty fine device so try swapping w/ some1 or something similar
Impossible? I'm chatting with my phone operator (Telenor) about operatorunlock-code. And as far as I know, the operator-code will make the phone accessible for other operators.
But the issue I got right now is there is no place to enter this long operator-code
I mean: impossible to unlock by yourself if operator doesn't allow unlocking or bills it insanely, and you don't have the money/don't want to pay such amount.

Put in a different operator's sim card and restart the phone.
It'll automatically ask you for the code

I didn't happen to have a microsim from another carrier so I decided to cut one up. For my first attempt I did a pretty damn good job since my phone recgonzied it!
Got prompted to enter an Unlock code.

try this !!
My problem is that when I use a SIM from another carrier and boot my phone up, I do NOT get this: “SIM network unlock PIN” message. My phone only says "SIM card is locked" and want me to type in PIN.

Seems your SIM card is locked. I remember old phones gave you an option to add a pin code onto the sim card itself. There was a warning that if you forget it you're screwed. Try getting a new SIM from the carrier

Where to get free unlock codes or to go bring it into a location to get unlocked

Does anyone know where I can get free unlock codes for my AT&T Jetstream tablet?
Does anyone know of a location to bring my AT&T Jetstream tablet into in the NYC & NNJ areato get it unlocked. Please help.
what do you want to unlock? SIM, bootloader, ???
If you plan to travel and need to change the SIM, call AT&T customer service they will give you the SIM unlock code.
If you want to unlock the bootloader and change the Kernel and/or ROM go to htcdev.com and unlock.
I did it in eBay for $3 (SIM-unlock)

I need to borrow a Sim card from someone so I can unlock the Sim. I was told that will prompt me to enter a code to unlock it. Will ANY Sim work? Even if it is a Nextel Sim card?

Any sim will work-inserting it will prompt you for a code. But to get the code, you need to get the unlock code from either AT&T or use online sim unlock sites.
Regarding the borrow part, you can just use your regular mobile's sim to unlock it. However I think there was a thread that had something about some changes with the data and stuff with AT&T happening on removing the sim. Read it up and make sure to get AT&T's help once you change your sim back to their's after whatever use you intend to do.

What do you mean aboutbchanges with the data? If I will be using another carrier then what do I care about AT& T's data changes?

I thought you might be going back to AT&T. Hence. Any case if you plan on shifting permanently, just go ahead.

What I would be hoping for now that I have gotten my HTC Jetstream Tablet SIM Unlocked, is that CLEAR comes out with SIM Cards. CLEAR has Modems, Hotspots, and USB Hotspots. They should come out with SIM Cards now since there are a LOT more devices that can use them for just the reason of why people get the Mobile Hotspots.

Changing carrier and phone not working with new SIM

I have been using ATT service on this i777, now going to China and will be using their carrier for a long time. I learnt I have to go to either China Mobile or China Unicom if I'm to stick with this device. However both carrier's SIMs resulted in "SIM card not provisioned" notice and it's not working.
I am wondering if calling ATT helps, or I need a SIM unlock code, or I have to install a custom ROM to somehow bypass the SIM check? Or even more? I love this phone so I don't want to buy a new one here in China.
Any help is greatly appreciated!!

Your phone needs to be sim unlocked. If it is not unlocked already, then by far the easiest route is to call AT&T to get the unlock code.
oh I'm sorry, I think I already unlocked it (spent a few bucks and got the code on a website)
I put in China Mobile's SIM and entered the code in the prompt box. Do I still need an unlock code from ATT ?

Thanks for the reply. I replied you above but didn't quote.
If the phone is already sim unlocked, then you don't need to unlock it again.
I've never gone through the unlock process, or traveled over seas, so I'm not the best person to answer your questions. I think "not provisioned' indicates that the sim is not activated, or that the phone is not set up for the network, or something like that. You may need to input the correct apn for the network. Maybe you could go to the carrier's store and find someone who could help you?
Maybe someone with experience will jump in and help.

Sim network unlock PIN

Hi everyone,
Everytime I open the phone I'm asked to enter a Sim network unlock PIN.
At first I talked with my carrier, which tried to give me few PINs to unlock the network lock, but none of them worked.
After reading a while on the internet (and also as it says on the box) I suspected that this is about the Region Lock samsung implemented in it's new devices.
I bought my device in Europe (and well, I don't live in Europe).
I talked with the shop I bought the device from just to make sure the device is not sim locked, and they claim that they indeed sell only sim free devices, so I turned to Samsung.
After talking with Samsung in the country I bought the device, I was given an unlock PIN, but unfortunately, it doesn't work.
Do you have any idea what could it possibly be?
Maybe I tried too many times wrong PINs and the network is locked now? Don't know already....
P.S.
All the phone features works fine (if I go out of the screen with the PIN request), except for mobile internet and calls of course.
Images attached below.
They claim wrong that my friend is sim locked & you will need to find out what carrier its locked to, that carrier will have specific codes.
At least that is my understanding.

Thanks, but based on what info are you so sure?
I talked with the shop again and they INSIST their devices are sim free.
I need to have some kind of proof to argue that.
And also, I'd like to hear more opinions please...
BUMP - any ideas please?
Have the shop were you bought it from replace the phone or you can call the carrier that the phone is lock to and request the unlock code. It should be very easy to determine that by firmware build number (For example: G925P is Sprint)

Just confirmed it's a G925F... so it's not sim locked, as the shop stated.
This phone is simlocked to a network. You need to find out what network it is locked to then get a unlock code.
Once you enter an unlock code it will be unlocked to all network....

Ebay is a cheap place to get unlock code but you NEED to know the original network

Why can't it be? that is a model number for UK handset but it doesn't mean anything else. All UK and europe (also middle east) models are G925F , some are network locked and some are not.
Accept it and do something about it. Ask for refund or ask the seller to get you unlock code.

Ok thanks. Thought all G925F are sim unlocked and cannot be locked...
Is there a way to tell the network it's locked to? (because I know what the shop is going to say: "no, its not unlocked so we dont know the network...")
Not sure, try GalaxSim Unlock from the play store. It might tell you

Doesnt seem to support S6.
Regional Lock
Your phone is regionally locked., which means you should unlock it with a Europian SIM card before using in an other country.

What you need to do is check with the shop where the phone came from? Which country the phone was bought. Once you know that you can try different sims (they are freely available from providers or ask your friends). The unlock code is a combination of Phone IMEI number and the network so you need that information.
Let me know how you get on...
