The carrier the device is locked to. For me I'd have to get in touch with O2 to unlock my device for example.

Wait let me think.... sim lock is carrier related in that your device only allows certain sims. Therefore your device is locked down to a carrier, unless I've completely misunderstood!

Its working for only one company sim cards. So yeah if I dont have this sim card from this company it wont work.. There is way to pay like o 4-5$ to unlock it. But wanted to ask if there is any free solution.
Otherwise I will have to pay ;(

I'm glad that you are doing well, good luck to you.

You would have to contact the carrier, who's brand is on your device for the cell network unlock code.

I need help fast, my friends

Hello my friends, I need your help
I had bought a mobile x10a from canda
i bought it from a telecommunications company at $ 240
Is a device used is not new
The problem is that the device does not accept any SIM CARD .. Only offering from the company
So .. I've bought from the company code to make the device work on any sim card at $ 35
The company is a code that puts in the phone and I'm not I who put it
Mobile version 1.6 ... So .. I want to update to 2.3.3
Can I do it without problems??? Or will I need to buy a new one to break the code
What is your opinion in this problem?? ... Please help me
I think SIM Card lock will not affect the update process. Be easy my friend.

Code has been developed by the company and I do not have a copy of it
This is the last comment I will make on this topic it is getting annoying now. The code is PERMANENT. I know that because...that is what the code is supposed to do. PERMANENT UNLOCK. It doesn't matter if you root it, update it, go back to 1.6 or go to 2.1 or go to 2.3.3. It will ALWAYS STAY UNLOCKED. Please stop asking questions over and over again. If you do not believe me than that is your problem.
thank my friend for you comment

How to remove simlock on xperia s?

Hello Guys
I have a stupid question, can someone tell me how to unlock Xperia S so that I will be able to use any sim from any network? I have a chance to buy Xperia S on Monday but it is locked to 3 network in UK and I'm currently in Tesco Mobile. Please can someone help asap. Thanks
Maybe if you flash a world generic firmware.
Next time ask in Q&A forum.

Is that it? God I thought it will be much harder because I couldn't find it anywhere how to do it. The only way to do it I found was to buy an unlock code for £44 . Sorry for posting here, next time I will write in Q&A if I will have a problem like that. Thanks for your help

I just phoned o2 as they are my network provider and they gave me the unlock code, put a different SIM card in from a different network and put in the code.
I thought they had to.

That's why I am informing you. If you ask them to unlock a phone that was sold as a contract violation, it won't do you any good.

This would be the case if the original person bought it with contract. But if he got it sim free( pay as you go), then it is legal.
To answer the original question, the only way is to phone three themselves and ask for unlocking code, I think it is 20-30 pounds
I recently bought the Xperia U for my partner that was locked to the 3 network. They will unlock it, BUT the person on the contract will have to make th call and they will supply him with the code, can take up to a week for it as it comes from Sony themselves. I think the cost was about £15 for it.

[Q] Unlocked Phone but keeps re-locking

Hey, all
I've recently aquired a Samsung Galaxy S2 GT-I9100p Which is the version with NFC which if I'm correct is an american important?
I am from the UK.
So basically I edited my nv_data.bin so that my phone would be come Network Unlocked and it keeps resetting the Network Lock.
I have tried the following apps :
Galaxy_S Unlock by Helroz
Samsung Galaxy S Unlock Tool by DaGentooBoy
[Root] Galaxy S2 SIM Unlock by Chainfire
[TOOL] Samsung Network/Sim Unlock Code Generator/Patcher (SGS1/2/3) by AdamLange
Non of these work and I can't seem to figure out why I have to delete my nv_data.bin from my phone and replace it with edited one on my SDCard then reboot and I have Network unlock for about 4-5hours then it disconnects and I have to do it again.
Can anyone possibly help me with this?
Thanks in advance to all.
EDIT --
Before anyone goes use the search buttton...
I have used the search button and I can't seem to find the answer I am looking for.

GalaxSim Unlock is now available in the Google Play Store here. It's free to download, with in-app billing to unlock, for what I believe is a fair price.

No problem mate
I am really upset that I have to keep deleting my modified nv_data.bin and replacing it to make it so my orange sim card works hehe
Thanks for the advice tho I will have to try it out if I can't find and alternate..
I would pay but I don't know how much it will cost and if it costs more than £5 I would pay I would take it to the local market
@OP, the link of the app IS for the FULL version of the APP... the one on the market is the one with the in-app billing... i just downloaded the app from the link and it worked for me(free)
Edit: The apk in the link is missing the other "Features" that the owner writes about in the post. But it does unlock for free.

Is the GTI9100 unlocked?

I have galaxy s3 with a straight talk micro sim in it (the bring your own phone sim, cost 14.00 bucks). I bought a used GTI9100M s2 and re installed the stock rom because I wanted to remove the root from it. when I install my sim for my s3 with the adapter from mini to micro, it gives me the ENTER NETWORK UNLOCK CONTROL KEY BOX. I though the GTI9100 was unlocked as it is the international version. So why is it asking for a control key?
I just want to be able to use gti9100 for a backup phone in case my s3 breaks. can I switch the sim back and fourth like this?
Thank you for any advice.
You need to unlock it. Being the international version doesn't mean it's unlocked per se.

Do I need one of those unlock codes off the internet that cost about 10 bucks?
Also, can you or someone tell me if by doing this I'm unlocking the phone or the sim card itself? I don't want to cause a problem with my sim when I put it back in my S3, thaks
You can unlock it by searching the forum. There's a thread about this resolved yesterday at q&a.
And no, it won't affect your sim card at all, it will only unlock your phone.

I want to thank you for your help first, but I'm wondering now why I bothered getting a GTI9100 international if I still have to unlock it. All I've seen people saying is, " just get an unlocked phone, that way any gsm provider's sim will work with it".

Anyone SIM unlock Sprint galaxy mega yet?

I have two of these.

Nevermind.
VirtueToVice said:
As far as I'm aware, the Sprint Mega, like many Sprint devices, are strictly CDMA. The only exception I can think of is Crapple products which can be GSM unlocked with something called a GEVEY SIM which in my experience isn't exactly reliable. Anyone can correct me if I'm wrong but I believe the SIM card in most Sprint devices only controls the 4G LTE so it's sorta GSM but not really. My suggestion would be to look into getting the phones "flashed", or reprogrammed for another carrier. Here in my locality flashing CDMA devices to nTelos is extremely popular, as they have a $45 unlimited everything plan with no real data cap. They simply do a SLIGHT throttle after around 15GB. There are several other CDMA prepaid companies across the US. The only nationwide ones I can think of are Pageplus, Selectel, and maybe Straight Talk. All offer low cost unlimited plans. Some have data caps and throttling, but pretty good bang for the buck! Should you decide to try and flash for yourself, Wireless Workshop offers a "trial" account, if you can provide any kind of company information. We use them at our store and they can flash pretty much any major handset. All said and done, look into flashing those to a prepaid carrier, as these are AWESOME phones. Good luck!

Dude don't go telling everyone about how Sprint phones are strictly cdma. Im tired of people on these forums spreading misinformation. This is not the year 2008. Back then all Sprint phones were strictly cdma. Not so today and yes the Sprint mega has gsm capability. It's even listed in the settings, but is greyed out. So the Sprint galaxy s4 is strictly cdma too? Lol go do your homework.
Sent from my SM-N900V using xda app-developers app
"as far as I'm aware"
I was simply offering what I did/did not know for sure, and some information for a way to take it to another carrier that I DO know about. For one, I've never had a fully operational Mega in my hand to see that it offered a greyed out GSM menu in the settings. My bad, dude. :good:
In fact, I'm trying to resurrect one right now. Software is totally borked.
Anyway, good luck figuring out the GSM unlock!

I successfully unlocked the Mega to work on T-Mobile as well as the Sprint Note 3, Sprint Note 2 and Sprint S5
I'm working on making a program to UICC unlock the device without having to call Sprint to get it internationally unlocked, I also have a program that will open the service menu option to reprogram the phone if you cannot reach it through dialer codes.
Quite simple once you get the whole process down.
