Hello everyone
I have network problem on my Galaxy S4, I bought phone in South Korea he worked fine. Then I back home in Uzbekistan and found network problem. Phone doesn't allow local operators sim card. I tried most of methods to sim unlock, but still doesn't work.
Service menu (*#0011#) is hidden
IMEI (*#06#) not available I can't backup
I can't activate root
Update firmware not helped
Someone knows any effective methods to unlock sim?
Regards!

Hi!
I bought an Note 3 N9005 and I noticed that the imei the phone displays it's different than the one on the back and on the box.
I have to select the network manually and it only works on EDGE when I'm on the web.
Could it b3 that the phone was sim locked and during the unlocking the imei was changed?
If so, what can I do?

Hi,
I have a brand new Galaxy S4 i9505 that was purchased from the EE network in the UK and is currently locked to EE - I would like to get it unlocked
Android version 4.4.2
Baseband version I9505XXUFNC4
Kernel version 3.4.0-481100
I have purchased unlock codes (sim, region and 'defreeze') from a reputable eBay seller but these are unfortunately not enabling me to unlock the phone from the EE network - I want to be able to use it with the Vodafone Ghana network in Ghana, West Africa
> When I use the unlock method that starts with dialling *#0011#, I am unable to access the UMTS menu;
> The method using code *#197328640# is not working with this handset;
> The method using code *2767*3855# is not working with this handset;
> The method using code *7465625*638*# is not working with this handset;
The retailer of my unlock codes advised me to check that my Samsung software is up-to-date but I've checked and it's already running the latest OS - via Kies I was unable to access any more recent updates.
I would be very grateful if someone could please advise how I can get the handset unlocked and whether it looks like I will need to Root it?
Cheers,
pbt04
Use this post and thread as a starting point.
You probably need to flash an old modem.

Hi, first of all, this phone has been flashed to XtreStoLite ROM, which is based on a G900F firmware. Prior to this, the phone has been unlocked by the shop that the phone was bought. S5 G900L is a Korean model and is meant for the LG U+ network. The phone was able to pick up LTE signal in my country (Brunei).
The phone is unable to pick up LTE signals despite on the Network Mode option, there is an option to select LTE/WCDMA/GSM mode. Is there a code that I can use on the phone dialer so that I can activate LTE?
What I meant is something similar to this: http://forum.xda-developers.com/lg-g3/general/mod-root-activate-lte-g3-t2819387
I have tried to dial ##3282# but it does not do anything. I think it's only for the Sprint S5.
The same goes for:
To tell what Band on: ----
1. ##debug#
2. enter passcode 777468
3. go to LTE engineering menu

As for my next question:
When I flashed a stock G900L firmware from SamMobile, it won't read my SIM card, and it seems that I have to use a LG U+ SIM card from Korea first. How do I make the phone able to read my SIM card from Brunei?
Bump.

- As for secret code ##3282#: First, the secret code format of Samsung is *#xxxx#, not ##xxxx#. Second, to see ALL AVAILABLE secret codes in your device, install Phone INFO ★Samsung★ app > Menu > 'Secret Codes'. That way you will know the code 3282 does exist or not.
- Regarding LTE signal, may be your phone does not have LTE bands that your network currently supports. To check for what LTE bands your phone has, enter *#2263# and select LTE Band Preference to see a list of supporting bands.
- If the required bands are missing, you may want to add it to your phone? Try this thread if any luck.

AT&T phones are network locked. Not region locked. I used my S4 (with roaming on) in UK, Canada, Penama, Korea, Thailand where AT&T local network is available. To use local network or other network, your phone need to be network (sim) unlocked.

I am an AT&T user for 20 years and AT&T always deny to give me the network unlock code. They do provide the network unlock code for the iphone users if they the phone was already paid off (after 2 years contract).
When I asked the network unlock code for my previous AT&T phones, (nokia, LG, HTC) AT&T told me to use the AT&T roaming network and they put me on the worldwide roaming program.
When I tried to unlock my S4 i337, AT&T asked me to go to a link for the unlock instruction but S4 was not listed in there. AT& T told me that if the phone is not listed they could not provide the unlock code.
I end up using cellunlocker.net for all my phones network unlocking. It cost about US$ 30.00 .
You can try to request unlock code from AT&T first at www.att.com. Explain to them about your situation. They might help you. If they denied, just use the paid service like I did.
If AT&T doesn't provide a free unlock code, try ebay.

The free method seems to work on very old bootloaders and modems.
Hi .
I have bought a S8 locked to US Cellular on eBay, clean , not blacklisted and when I try a SIM card from my operator does not ask for unlock pin code and remains without registering on my network.
Does anyone know any website or any method to unlock It?
Many thanks in advance.

Does it have a unlock app in apps drawer or in settings. It may be unlocked. If ure sim works. WhT carrier you on.
Thanks for your answer.
I live in Portugal and I tried 2 different SIM cards. The phone shows in upper left screen the message "SIM blocked". I searched for an unlock app too but I can't find any like in T-Mobile phones I bought in the past.
US Cellular is a CDMA network provider whereas in Portugal you probably have only GSM networks.
I think you should look into this and investigate this issues as well.
Another info: I flashed with Odin with the latest USC official Rom from sammobile. Can be this the cause?
This is 950U version and therefore has the GSM frequencies as well.
Even if it was only cdma it would prompt to insert the network unlock code....
Any help?
WHen I put a sim card it appears a forbidden sign on the top, where I should see the network signal...
