Hello,
I have an old galaxy S5 I am trying to network unlock so I could get rid of it. I called Sprint to get it unlocked, and after a long time being placed on hold, I was told the phone is not unlockable. However, they provided me the unlock code. I tried putting on a different carrier sim expecting to be prompted to enter the code, but that didn't happen. I only got an invalid sim error.
What can I do?
EDIT: it is possible to unlock, see below.
It is not unlockable with some "unlock code", you have to hack the modem firmware partition and flash it to the phone.
There was an online unlock service for $35 at http : / / idoneapps . com and I've successfully unlocked 2 phones with their service but the website does not work anymore, also they do not reply to email or facebook.
If anyone knows the similar service - please share the link, I'm interested too.
I've managed to unlock the G860P for international SIM cards, check this thread: https://forum.xda-developers.com/t/confirmed-sim-unlocked-s5-sport-g860p.3128965/

Hello all
This is my first post here, but I have been reading a lot for some days now
So this is the issue
Some days ago I bought on ebay from a reputable seller the sgs2 stated as unlocked for all networks. This is a UK phone but I am located in portugal, and I use a vodafone sim card
Much to my surprise I was greeted with the O2 logo when turning it on.. oh well.. no big issue on that but...! right after entering my sim card pin code it asked for a network lock control key.!
Trying to avoid too much assle for being a newbie in android I bought an unlock code from mobileunlocked, and well, it didn´t work! says "requesting network unlock" over a fraction of a second and then right afterwards "network unlock request unsucessfull"
Ok, so I went the hard way and read all about firmware and rooting at the android development part of the forum
Was able to flash the XWKE7 / baseband XXKE4 with odin, was able to root it with intratech´s thourough instructions, no more O2 startups or logos, even installed the galaxy S2 sim unlock (it finds the same unlock code I got before, and it is probably right)
but.... the dam unlock code question does not go away, so I have no mobile network at all!
Seems it tries to communicate with O2 for the unlocking but of course I am nowhere near the UK..
So I have a fantastic up to date piece of brick in my hands!
Could someone please help, how can I get over this network unlock code ?
I am running out of options, please help!
best rgds
Buy a code from somewhere online instead. They're more reliable then the app unlock.
Samsung phones can be locked by 4 methods methods but generally the first three are what you are interested in .
1. [NCK] Network lock
2. [SCK] Subset lock
3. [SPCK] SP lock
4. [MCK]
o2 generally only lock down NCK
1 ensure you have down the correct IMEI number , when you got your network unlock code was it just the unlock code they gave you or did they supply the above too.
2. you do not need to have an O2 sim to unlock as the procedure means you need to put a different sim in to enable the codes .
3 mobileunlocked.co.uk are very good and if you contact them they will be able to help you . Send them an email .
Hope this helps but just make sure you entered the correct IMEI number *#06# from the start .
good morning
indeed they do, I bought from them. I had to enter the MCK and then the NCK
how could I know ? lolol
also thank you guys for your prompt help
turning on the little devil as I write... ta nan!
I have an 1.3 rev Samsung Focus. It was an unlocked model I got from outside. I was in the US at the time of Mango update and updated my phone with Mango from AT&T. Now I have moved out of the US and want to unlock it. AT&T doesn't have the unlock code because I didnt purchase it from them. Any Ideas on what I can do? Will a custom ROM help me with Unlock? When I check lock status, it is SIM Lock is Disabled, only Network lock is enabled.
I'm not sure what you meant by "It was an unlocked model" in the context of "out of the US and want to unlock it". Was it unlocked or locked? Anyway:
Read the wiki, (carrier) locks are in NVRAM, no relation to flashing whatsoever, so any custom ROM won't SIM unlock your phone.
Have you tried ebay? Unlock is cheap as $1 and it doesn't hurt to try (unlock via IMEI - I unlocked AT&T and Rogers Focuses). If that fails, I recommend fastgsm, I've unlocked my own AT&T Focus with them, via USB (no affiliation).

It was carrier unlocked, as in I could place any sim in the phone and it would work. After I updated it on my Zune with Mango, it was loaded with AT&T's version and hence locked to AT&T. Now AT&T doesn't have the record of the IMEI in their database and aren't able to provide me with an unlock code. They were able to provide the unlock code for my other windows phone that I purchased from AT&T. Thereby lies my predicament. Let me try the ebay version, if not I hope FastGSM works. Thanks.
I was not able to get the unlock code from ebay. But FastGSM seemed to work wonders. I used their USB unlocking tool and it worked just fine. Thanks for the tip.
Seem s TMO G5 is easy to be unlocked to use other GSM carrier.
Many unlock service website say they can unlock it by several steps.
Typically check if the H830 can be unlocked, by following these 3 steps:
1. Install T-Mobile APP from Play store.
2. Open the app and press Permanent unlock.
3. The following message should appear: Unlock Failed: This mobile device is not eligible for unlock. blablabla...
And if you get a different message you CANNOT unlock this device.
So question is coming.
Is anyone experienced in this thing? In which cases G5 will appear "Unlock Failed" message?
I guess if the phone's IMEI is clean but not use TMO network for enough long time or just even never activated on network then we can pay extra money to that kind of website to unlock the phone. If IMEI is in blacklist so the problem is not just like "this mobile device is not eligible" so simple .
Am I right?
Hi All - I recently bought a Samsung Galaxy S8 from someone else. It worked fine when I was with T-mobile but when I moved to another network and popped in a new SIM, it asked me to "Enter network unlock code". I figured it must be locked to T-mobile so I reached out to them. They said my account met all the unlock criteria and said they'll send me instructions via email. I got the email two days later saying I need to use the "Device Unlock App". However, there's no such app on phone and there's no way to install it either (its not in the Play Store). I went back to T-mobile and they said since the device wasn't purchased through T-mobile, its not be a T-mobile "branded" phone. My questions are:
1. If its not a T-mobile branded phone, why does it only work on the T-mobile network? I checked its not rooted. It doesn't have any T-mobile apps and doesn't show any splash screen with the T-mobile logo.
2. Someone said that Samsung GS8 locks to the network of the first SIM you put into an unlocked phone. Is that true?
3. T-mobile says they've "whitelisted" my IMEI, so if I can somehow get the Device Unlock app I may be able to unlock it. Any idea how I can do that? Do I need to flash the firmware and install the T-mobile version or is there another way.
Thanks!
If you need to app, you can try here: https://support.t-mobile.com/docs/DOC-14011
However, as your phone is asking for the unlock code, the app might work but not unlock your phone.
You really need to do a network check and see which network is your phone actually locked. If your phone needs unlocking code, you might need factory level codes.
I think you should visit :

I have a ATT 930A that I successfully flashed with 930U and it works great. I was thinking of making sure it was SIM unlocked in case later I wanted to sell it, so I made a request of ATT for the unlock code but when I try it it tells me the unlock was unsuccessful. Do I need to go back to 930A to make the code work?
Probably yes
I don't think so. Just put in a non AT&T SIM and it's gonna ask for an unlock code

I did but the code att gave me didn't work.
So did the phone prompt for a SIM unlock code and you typed it in, got an error? What is the error? SIM lock should not change when you flash different ROMs yo the phone.

Yes, after entering the code it says "incorrect network unlock code entered"
I had this problem with my S7. I had paid off my contract however every time I tried input my IMEI number to the AT&T unlock device website it would tell my my IMEI is invalid. i contacted AT&T customer service directly and gave them my informatio. They had to put the case in for the unlock code themselves. Reason was since i didn't finish the 2 years even though i paid off my contract it got lost in the system hope this helps
