I've Boughten an unlocked Galaxy Note 3 SM-9005 on ebay. To use for straight talk in the United States. The first sim card i had in it was a normal sized sim card that i had cut (instead of micro) And after fiddling this sim card had worked from 4-5 days. Then i started to get the error message "No service" and "Not registered on Network" I had figured the sim was probably the reason to why i was not being allowed to call or message. So i bought another brand new micro sim card. And then put that in (Again with straight talk) and i am still unable to call or message. I have checked my imei number and it is the same as the one on the back of the phone. I have tried to re-register on the network within the settings on the phone. With no luck whatsoever. I have noticed that the CSC is not correct for the united states. And in hopes of fixing it i rooted and installed a custom rom. (IMEI is still the same)
If someone could please help...I am Stumped[/FONT]

Given the details that you have provided so far the most likely scenarios that I see are:
1) there is a mechanical problem on the SIM contact
2) the seller was on some form of a contract and has reported the phone stolen, so the IMEI is now blocked on some or all carriers.
DO NOT MINGLE WITH THE FIRMWARE at this point (and also disable any automatic updates of the firmware).
Also if you want further technical info (and not just guesswork) you should post the output from *#1234#

It really does depend on the issues xclub has brought up.
If it was me, I'd rule out SIM issue (the card itself) due to having a replacement, although it could be an issue with the SIM Tray.
And if it is used, then yes it is possible that it has been blocked by the original owner.
EDIT : Do you guys in the US have an IMEI checker for blocked IMEI's etc? in Europe we do it's called CHECK MEND.. Might be worth having a look or alternatively give your network a ring, they'll know for sure.

Ok so you have the same firmware as me, I am using BTU which is UK (I am UK) - So your CSC does indeed need changed to match you for US use - -- Firstly does your network support the available frequency required? (do you have LTE?) - If so you can change you CSC to your required region But another factor --- are you aware of region lock? has it been disabled that you know of? - this could cause some issues if it hasn't been deactivated - I'm not sure when changing CSC/firmware if it reactivates region locking or not
EDIT: I think only T-Mobile supports the N9005 in the US ( I could be wrong) --- Need a US user to chime in here I think to be 100% sure!!
Going with an Unknown carrier on CSC/FW- May not solve it

Don't see why not, plenty of people are buying them and plenty selling them.
majority of users have no idea what Knox is tbh, it's ultimately up to you if you disclose this to them or not.

That looks like EU version. Since somewhere else you mentioned that you rooted then the next thing to try is Region Lock Away:
http://forum.xda-developers.com/showthread.php?t=2470551
since the phone might now be "hit" by the EU region lock (an even simpler test would be to insert an EU SIM just to see if it registers on some network for roaming). If RegionLockAway fixes things you can then see what version of firmware you want in order to get LTE from your carrier.
If you want to sell the phone - being rooted might even be a plus, but having Knox 0x1 is certainly a major minus.
I did get region unlock and it did not work. And when i try to install the unknown firmware i am unable to flash it with odin i get all sorts of errors (I tried two of the unknowns) BTW thanks for the help
Please help, I flashed it to Android 5.0 and I did root for it and used region unlock app and still I face the same issue, please help me

Does your provider offer 4G? How old is your SIM? Is the firmware suited for the country you're in?

After reserching about it, I have read that that CSC is not per provider but group of provider.
So i should find a parallel rom that would work shuld I ?

The problem is that each CSC and firmware version has a different list of 4G activated providers that are not directly related to the region they are in.
Which means that a device can have 4G activated for 50 providers, just not the one your SIM belongs to. As such, if you insert the SIM, the 4G toggle is disabled.
Each provider has to individually pass on the fact that they have 4G to Samsung. Even then it's not activated for each CSC.
For instance, DBT (Germany) may have 4G enabled for all of Germany, as well as T-Mobile NL, Orange FR and a handful of UK networks. At the same time and on the same firmware version, 4G in the PHN rom (Netherlands) may not support any 4G network in Germany.
I've even had it happen where my Note 3 runs on DBT, and I had 4G on T-Mobile NL... Whilst none of the TNL (Branded) firmware had 4G enabled for their own network yet. (They didn't find it nearly as funny as I did when I brought that up at HQ...)
You either need to find a firmware which supports 4G for your provider, swap providers or you need to root.
If you're rooted: use a root-enabled file manager > open /data/property/persist.radio.lteon file in an editor > set it to true > save, exit and reboot.
LTE / 4G
Mine is P905M - LTE Brazil
I have no option to set only lte/4g... i just have:
LTE/WCDMA/EDGE - Auto
WCDMA/EDGE - Auto
WCDMA - ONLY

My question is: Have a way to set: LTE - ONLY ?

If you are rooted, download and install Xposed framework. Then download and install Intelli3g (from the Xposed downloads or Play Store). Activate the module and reboot. Then enter the app and activate fast mode toggle. Then select in the fast mode menu "LTE only". That's it.

If you input that code in the dialer (correctly) it should take you to a screen called "Testing". If it doesn't then there is something wrong with your phone. This works on pretty much all phones.
@GDReaper: The Galaxy S4 does not recognize that particular version of the USSD code. It can be run however through the Phone Info app.
@khsh97: Please post the following information:
1. Model Number
2. Android Version, found by going to Settings > More > About device.
3. Firmware Version (AP, CP, CSC), found by dialing *#1234# in the dialer or by installing Phone Info from the Play Store and running it.
4. Service Provider
5. Country
6. Is the phone rooted? (Yes/No)
7. Is a custom ROM installed? (Yes/No, and the name of the ROM)
Before using GDReaper's suggested method, post the information requested, so that we can eliminate other possibilities for why you don't have a LTE option.

I ran the code before posting and it worked on my S4. However, am running the gpe rom. Maybe that's why it actually worked
That is probable, as I'm running a rooted and debloated Touchwiz and it didn't work. But as mentioned, the Phone Info app is another way to get there.
Sorry for late reply!

My phone is rooted with towelroot however the option was missing before root as well.
BTW, I don't have LTE sim, does that matter?
If that matter then how can I check without LTE sim?
And yeah, the code *#*#4636#*#* is not working in my galaxy s4.
I am going to check out phone info app.
If you don't have a LTE SIM, you won't have LTE as an option. Upgrade your SIM to a LTE version and you should then be able to select LTE.

Ok, thank you...!!!
By the way, why the code is not working on official touchwiz roms?
Ask Samsung that question, but don't expect an answer. There could be a multitude of reasons why Samsung disabled it, but unless they pony up a response we'll never know.
Lol, Nice answer!!! Anyway phone info app can do it so why we should argue with samsung for disabling that code.
I think you must have firmware based on your country to have LTE. Now I'm downloading 4.4.2 for my country and I'll keep you posted
@velizarcho123: And you'd be wrong. LTE depends on two things: having a LTE-compatible SIM and having the proper frequencies in the radio chip to pick up LTE service. Assuming the device is neither region nor SIM locked, the moment you put in a LTE SIM Android will load the APN for the carrier into Settings. LTE should then work immediately. If it doesn't, the APN can be modified in most devices so it does work.
That said, if possible, using the firmware from your home region is the smartest idea, as Samsung does modify the firmware a bit, usually by removing languages other than those spoken in the region.

All firmwares have LTE, I does a trick - rooted my phone and modified a system file that enables LTE in the network menu. This is stupid Samsung restriction.

Reread my post. You were able to modify the firmware, but that modification would not have worked if the SIM wasn't capable of LTE and the radio chip didn't support the frequencies used.
EDIT: Just to clarify, Samsung modifying firmware to remove the option to use LTE does not mean the firmware doesn't support LTE. Clearly it has to support LTE if your modification worked. This means that firmware is eliminated as a variable, leaving the two remaining variables as the SIM and the radio chip.

Are you sure that US unlocked model on T-Mobile isn't getting "4x4 MIMO & 256 QAM"? In the specs on Samsung website it shows: VHT80 MU-MIMO,1024-QAM, don't know if it is any different.

How to verify that SM-G950U1 do or does not support 4x4 MIMO & 256 QAM on T-Mobile? I might flash my unlocked unit to T-Mobile only if I know for sure that my device doesn't support it.

I'm not sure if it does yet but I would assume so since you are flashing the T-Mobile firmware .. I have tried many different methods of finding out if it does via the device but I think you need root. I tried multiple applications from the play store and used multiple phone codes to open every menu available. I got to the ServiceMode to change bands by using *#2263 / I got to ServiceMode with Debug that gives information about the current Band that you are on and how many MHZ you are running at. It also gives you some additional info: RSRP RSRQ SNR. Unless somebody else has a way to figure this out without root I'm not sure. Also Ill add a list of the current cities with 4x4 MIMO below. I did verify that all HD Voice, Wifi Calling, Video Calls, & Volte work .... Verified by downloading Shortcut Master Lite https://play.google.com/store/apps/details?id=org.vndnguyen.shortcutmaster.lite&hl=en ( Under App Explorer / System Apps / IME Settings / ImsSettingsLauncherActivity / Launch ). I am happy with the TMobile Version .. It has T-Mobile App installed and Lookout but there is ways to disable those and remove them without root. I haven't removed them but i read it is possible ... Doesn't use much RAM. If you need anything else let me know!

So from your 1st link, I do see that my city is there (WA), but second link, didn't have it.
I have done flashing via Odin many times on my previous Galaxy phones, so I feel comfortable, but I am kind of debating...if I really need to flash and if I will benefit from this.
I will ask you few questions and it may help me make a decision:
1) Have you measured download speed using Speed Test before flashing T-Mobile firmware? If yes, any difference?
2) I hear that my phone calls are clear and pretty positive that HD Voice is there, even though there is no icon.
3) VoLTE, Band 12 and WiFi Calling are supported and work well. Never had a reception issue or call drops, at least not yet.
4) As for RCS support, do you see it often when you text other users?
5) Video calling - your phone should have it, have you used it?
6) How is battery life compared to an unlocked software that you had before?
From the list above, I would flash to T-Mobile if: #1, 4 and 6 are working properly to make user experience better. I do know that RCS even on T-Mobile is limited to phones that support it, for example Glalaxy S6, 7 and 8 and possibly Note 5. Also some LG phones I believe had it as well.
In other words, what did you gain when you went for T-Mobile firmware?
Before I forget, you used Odin and added needed files such as BL, AP, CSC(you probably didn't you HOME file, just CSC) and also USERDATA TMB file - I am correct?
Any updates on whether or not the Unlocked USA S8 supports 4x4 MIMO & 256 QAM on T-Mobile? I've flashed the T-Mobile firmware on my unlocked phone and haven't noticed any speed decreases or increases. Any new way to verify that s 4x4 MIMO & 256 QAM is actually active with the unlocked firmware? I believe it is doing 3x CA though...

I am trying to find that info for sometime... I have seen somewhere that there is/was an app in play store which was similar to LTE Discovery, but it did show more info on 4x or QAM, I don't really remember. That time I didn't need this info, so I didn't really pay attention. I found this site that has some info: http://www.howardforums.com/showthread.php/1888849-How-to-tell-if-using-4x4-mimo
Hello,
Yes, I've read and read again and searched as much as possible, but strangely enough changing CSC is not widely covered as root, for example, and I still have some questions.
So, as the subject says, it is a Latin America variant with dual sim and Panama (TPA) firmware. I can't specifically say why, but I feel like I want to change that. Perhaps faster updates; maybe ability to use functions that currently I can't (Samsung Pay?!), etc.
I am in the U.S. with main sim from TMO and second SIM from Israel. Current Service Provider shows
TPA/TPA,ILO/TPA
In Phone Info app I see the following:
Active CSC is TPA
Firmware's CSC is XEF.
1. What is the difference between the two (Active and Firmware)?
Note that I did not do anything out of the ordinary: activated the phone new out of the box, it downloaded some updates (before I put my SIM in, if that matters), and that's about it. So why would a Panama phone have French CSC and how come I don't see XEF anywhere in the phone info itself (only in this app)?
2. Is there a 'better' CSC to have compared to others, in terms of frequency/priority of updated, available services, etc? Phone Info shows a list of available CSC's to chose from (see below). As far as I can tell, the only two things that don't work for me are TMO Video calling and Samsung Pay. Will different CSC enables these services for me?
3. Are there any downsides to changing my TPA CSC to a different one?
I am sure I'll have more questions and I appreciate any assistance.

The Phone INFO App doesn't always reflect the actual firmware. Try Settings, About Phone, Software Information, Service provider SW ver.
Samsung Pay can work on the Exynos European variants but I haven't seen it working on any Latin American variants.
You definitely won't be able to use T-Mobile Video Calling on your firmware. Your only hope on changing the CSC is rooting the device however you'll trip Knox and lose your Secure Folder. It's an "Iffy" option and I wouldn't recommend it. You might want to review this thread for additional info, good luck!

Thank you @varcor.
Rotting is definitely out of the question, I don't have any interest in doing that.
What defines the phone as European vs. Latin, when both phones can accept (technically) any OXM multi CSC f/w? Is it the CSC itself (the last 3 characters after the sim info)?
BTW - INFO app shows the same details as About Phone (in my case).

It's for software compatibility for the most part, the hardware is identical with a possible exception in cameras. The CSC's will be different as well and they do affect software configuration. If you read the last few pages of the link I've shared you'll see some members claim they're having success changing their Active, SIM 1 and SIM 2 CSC's using Samkey, which doesn't require root. Remember the 4th CSC (Sales Code) can't be changed regardless. How well Samkey works on individual devices likely depends on the device, it's associated firmware and Service Provider. Not an interest to me as I mentioned since my device aligns and incorporates calling features based on the Active SIM for the regions I've visited. I have T-Mobile as my carrier which works with Telcel (Mexico). I'm surprised I don't need Telcel SIM for calling features, T-Mobile has eliminated that need as I get Wif Calling and VoLTE on Telcel's network.
