I'll try and keep this breif but getting pretty frustrated with this...
I bought this handset sim free from T-Mobile UK. It was brand new and sealed. When inserting my Three(3) sim it would say "invalid sim" - which was expected as it was locked to T-Mobile. I paid a third party UK company called mobileunlocked.co.uk who have a very good reputation and lots of good reviews for an unlock code so I could use it with a Three (3) UK 3G Sim card. I received the unlock code and an un-freeze code and used both several times, resulting in "unsuccessful". Thinking it was a bad code, I paid ANOTHER unlocking company off ebay (again, reputable) and was supplied with the same codes and the same results but a slightly different method which involved entering * and # keys before the codes in the code box. This resulted in a popup saying "Network control code is blocked".
Following this, I tried the *#197328640# method to access the hidden menus as detailed in this thread http://forum.xda-developers.com/showthread.php?t=2014982 (this has been proven to work with Note II, Galaxy SIII and Galaxy SIII LTE).
I followed that guide to the letter and restarted the phone. At first, I had hope as there was no sim lock code entry box, however I waited and waited and waited and the phone did not pick up my Three (3) signal, despite it no longer saying "invalid sim".
Basically, it just shows several bars but does not pick a Three(3) signal or any date. I have tried manually selecting the network and manually entering APN settings, but I get the same result. When I try connecting manually it just says "Cannot register on network".
-I have tried using this sim card in other phones, it works OK!
-I have tried using other network sim cards (Orange, T-Mobile, EE, Vodafone) and they all work.
-I have tried using a different Three(3) sim in this phone and it still doesn't work.
I can't return it to the T-Mobile store as the warranty is invalid as I have unlocked it (or so I think!). Can anyone help? I know three(3) sims are compatible with this phone as others on this forum have stated they are using Three (3) sims in unlocked i9305s.
Any idea why my unlocking codes that were valid wouldn't work and why it said "Network control code is blocked"?
Any idea why my Three(3) micro sims won't work but other networks do despite this phone being compatible with three (3) sims?
Help!
It doesn't appear that 3 UK has any publicly available LTE network at this time, but that they are rolling one out. Perhaps it is physically available and being picked up by your phone, except 3 isn't allowing just any sim card to register on that network at this time? Try disabling LTE and attempting to connect again.

I know I won't be able to get LTE as Three (3) aren't offering LTE until Q3. I am perfectly happy just using 3G. I have tried disabling LTE and using 3G only and the same things happen.
I have tried 2 different Three (3) micro sims in it and it still won't register on the network. I know Three(3) sims work in the i9305 as others have unlocked their's and used Three (3) sims.
It's either something wrong with the unlock, something wrong with the hardware or something isn't enabled/disabled. Like I said I've tried automatically connecting and manually entering APNs and still NOTHING.
Frustrating having spent over £450 on a brand new handset which I can't return as warranty is invalidated through "unlocking" (which hasn't unlocked it fully!)

Shouldn't be a problem to be honest. Have you tried calling three to say that you're using the i9305? I love three and their unlimited data plans I plan to do this once samsung/EE unlock my phone.

Hi,
I am in the same boat, I actually got the S3 LTE from EE in December (GOT IT FOR 359).. Initially, it worked with three after unlocking via xda..*#197328640# method ..But it stopped working or it was working intermittently...
So tried rining three..they said..ohhh our network is best and our (three) sims will work only in three mobiles..
Anyway I tried all other methods..re-set..factory etc..
Finally sent the mobile to Samsung...
after 10days, I got it back...Now as soon as I insert three sim..it says invalid sim..So tried *#197328640# method again..unfortunately..i can't do that as (the last option INITIALIZE...) does not show up now..
Anyway managed to get unlock code from ebay...NO USE..it shows the same problem as yours.."network control is blocked"...
Donno what to do??? might ring samsung again tomorrow...
Have you tried speaking to T mobile about getting it unlocked????
If you find any answers..pls let me know
Thanks in advance
I'm having the same problem. Any updated on how things went with T-mobile or does anyone have a fix?
Should I cancel my order?!
I just bought the S3 LTE i9305. I purchased it as an upgrade and its arriving tomorrow. I wanted to give my sim to my mother and keep the phone to use with Three's DC-HSPA+ which will work on the S3 LTE. So can I unlock it or will it be facing the same problems as mentioned in the thread. Sorry for not helping out, ama noob and GOOD LUCK! :good:
I recently put in an unlocking request at EE. They get a samsung unlocking code directly from Samsung. So I'll give this method a go. I am getting my Sim Card in soon from three. Decided to jump the boat on to the one plan @ £25 a month. =) EE's london signal is pants. =(

I tried to get an unlock code from T-mobile, they said that Samsung wouldn't release it for another six months, since it's a new phone. Even though we've been with them for donkeys years!
Right today, I recieved my sim. I'm glad to say everything works. I'm getting around 8mbps down and 1mbps up in West London.
If yours doesnt work then it probably is a damaged sim.
Tell T-Mobile you want to speak to someone that knows what they are talking about. It takes up to 60 days for direct Samsung unlock code. You might have to pay a tenner but worth it jn my perspective. I'm glad I have unlimited data again. It feels like freedom. No Joke. o2 Used to do an unlimited tariff and I loved it. There reasoning was to improve their network but instead it made it worse. I know Three arent known for their calls but they certainly know what customers want and thats data.
PS how do I know if im getting the optimum speed?

I think you have updated the software via OTA.. you need to downgrade to I9305XXALI5_I9305EVRALI5_I9305BVALI5 (this is for people who have got phone from T-mobile). Download from Sammobile.com, flash via odin (this wont affect ur warranty as this is stock firmware and doesnt increase the binary counter).
once you are sure that you have the above software, then follow the instructions on the below in first post in the mentioned link, again no rooting involved:
http://forum.xda-developers.com/showthread.php?t=2014982
People have confirmed that after unlocking via this method if you go ahead with OTA, you will still have the phone unlocked.
I have followed the above procedure but havent updated the firware and have not used the phone yet. But its unlocked and I have tried using Three UK sim, it works,
Do let me know how it goes.

On the site, it says it's for EE, is that still ok? I know T-mobile, Orange and EE, are all pretty much the same thing now, but I just want to be sure. I wouldn't want to put something that starts putting EE logos all over on boot up etc. The one that came with the phone doesn't mention anything about T-mobile on boot up.
It won't EE is unbranded
Thanks... I've zapped it with 4.1.1, used that trick, and then allowed the 4.1.2 update + plus another update of some sort through OTA, and I'm now using O2 happily! Cheers!
Phone arrived Friday on Orange EE with 4.1.2. wouldn't accept 3uk sim.
Tried the *#...640# trick but menu options not present.
Reverted firmware down to 4.1.1. Li5 Uk EE and voila menus present.
Tried 3uk sim and works fine.
Flashed latest Wanamlite rom and still unlocked on 3uk.
Getting a reliable 15.5 Mbs down on dc HSDPA at home despite only having 1 bar signal, on three One plan unlimited for £15/mth.

Great news!
So here's what's going on.
I have an Atrix HD that is rooted and the bootloader is unlocked already.
I'm trying to sim unlock the phone to use with straight talk or tmobile.
The problem:
When I insert the tmobile sim, the phone is supposed to prompt with a request for a sim unlock code.
This phone doesn't prompt and it doesn't show signal. "emergency calls only"
I've tried this with two different roms. AOKP and Pac. Both did the same thing. I've also tried a simple mobile sim with each of these roms with no avail. By the way, I do get service with AT&T sim on all the Roms.
What am I missing here?
I see all these threads about unlocking and the biggest issue people are running into is finding the unlock codes. They are out there but they're hard to come by. My issue is that even if I magically had that code, I don't have a way to enter it!
Thank you for any help in advance.
I've searched around to find a solution or reason, but apparently this isn't common.
EDIT:
In case anyone has the same issue, flashing entirely stock software fixed this issue.
It is now prompting for the SIM network unlock PIN.
I have an AT&T 920 that I bought 2nd hand and got unlocked.
I've unlocked a half dozen WPs, all originally Canadian phones, this was my first U.S. carrier phone. I went through the same procedure, non-carrier SIM, enter code, etc. And it appeared to have worked, but I tried two different SIMs and the phone wouldn't register with the network.
OK, so maybe some more fiddling is in order..
I then went through the procedure using the NCS to re-brand the phone to Rogers RM-820.
Once the Rogers ROM was installed, I had access to the diagnostics, including checking the status of the SIM unlock. Which showed as still locked. So I entered the unlock code I had, and now the phone shows as SIM unlocked.
I've also tried a different SIM tray for a 920 with no luck.
All of the above still did not solve the problem.
The phone "sees" the available networks. (Fido, Telus, Bell) But it won't register with them.
As the phone has a cracked screen, and I have a replacement for it, and I'm going to be opening it up, is there something physical I can check on the phone while I'm in there?
Is there anything in the diagnostics I should be looking for?
Hi There,
I have been scratching my head for weeks now with no luck after searching hundreds of times for a solution and I hope I can find it here today. I purchased an Sprint HTC One M8 from Best Buy together with an unlock code. I received the phone in Africa and I was excited to try it out. However, when I put in my local carrier Sim Card I could not receive an unlock code request. I tried many fixes but I did not get anywhere.
After days of trying one fix after another, I decided to unlock the bootloader successfully, install a custom recovery (TWRP), I was also able to achieve S-OFF using sunshine's tool and write CID to 1111111. After that I tried different kinds of unlock methods like using config.dat and using the Sim Unlock Helper tool. But no luck.
I went ahead and flashed my device with the Sprint M8 GPE 5.0.1 ROM. I was successful and I noticed under settings - cellular networks I am able to see all network operators in my region. However, when I try registering with my carrier I get a "Sim Card can not connect to this network" message. I do not know why.
When I dial *#*#4636#*#* and access phone information, I selected GSM only in preferred network type. Under select network band there are only 4 options: Automatic, USA Band, Band mode 6 and Band mode 7. I selected Automatic.
I have literally tried everything I can think of as I am kind of new to this. I really hope someone can point me into the right direction in unlocking my device once and for all. I love the phone and I do not wish to sell it off. Please let me know if there is any more information that I can share. Thanks for your time!!
Hello,
Are you still having this problem?? Cause if you do I am really curious if you found a fix for it? I am experiencing the same problems. A friend of mine gave me this One M8 which has no owner anymore so i decided to fix it. I replaced the screen due to water damage and did bootloader and root succesful. I can also see my network providers but as soon as I try to register it also says "Sim card cannot connect to this network". Who has the ultimate fixxx???
Greetings,
Rob
Hi all. I have an XT1097 that I have been trying unsuccessfully to network unlock. I have tried several unlock companies an all come back with the same 2 codes however they do not work. From what I can tell there doesn't appear to be a limit on the attempts. When I turn the phone on, it asks for the unlock code, but always comes back as unsuccessful. I have confirmed the IMEI a number of times so that is not the issue. I've heard there are a number of databases that the vendors can pull from. So far I have tried Cellunlocker.net, and Quickphoneunlock.com and another local person with no luck. I'm not a stranger to unlocking, but this is the first Motorola I have tried to do. Is there something quirky about them?
Does anyone have any ideas?
Thanks
I realize this is an older thread, but it's possible someone changed the IMEI. I got an HTC One M7 from someone, it was locked to T-Mobile. I tried unlocking it, but was unsuccessful.
I realized the IMEI was different that the one on the box, so I had to jump through a lot of hoops before I could get it rooted (this particular version had issues with most of the methods, ended up having to pay for an app to root it)... once I got it rooted and had access to the system, I could then change the IMEI back to the original one and was able to use an unlock code.
