If you dial *#*#4636#*#* do you get the testing menu? If so, go into Phone Information and check you are set to LTE/GSM auto or similar.

Sorry to bump old thread but I do not get any testing by dialing *#*#4636#*#*. I am on official stock kitkat.

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!
Model No: GT-I9505
Android version: 4.4.2
Firmware: I9505XXUGNE8(official stock)
AP: I9505XXUGNE8
CP: I9505VFGGNE8
CSC: I9505VFGGNE2
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.

N900 is your model, DDU is region code and ENG1 is version.
However DDU is not a CSC code, it is just a region code for a baseband, if I'm correct.
I guess your CSC should be INS or INU.
To obtain the correct firmware for your device, use Phone INFO ★Samsung★ app > Menu > 'Firmware Browser'.
Wiht that app you can also know your CSC code.

1. Install Kies 3 and conect your phone to the pc.
2. Take a look your CSC (pic attached)
3. Go to Sammobile.com and download the correct firmware (with correct CSC) for your device.

Hello Joku1981 !!
Thanks for the reply ... My device belongs to the UAE region and I am in a different one and the device don't have a firmware for the region i am in ... but I got it working through "Service Mode" *#0011# ... I changed the preferred network mode to GWL ... Though doing this doesn't make the option to be visible in More Networks --> Network Mode .. but I am getting the 4G/LTE reception on my device ...
Hey you or anyone else have any idea on how to make the LTE/WCDMA/GSM option visible in the Network Mode ... That will be awesome ... Thanks.
You guys rock ..

The final and correct firmware for you is this: ONE. This will give u LTE/WCDMA/GSM option visible in the Network Mode. Flash this firmware 2 times if you have problems with wifi or sound. Tell me how it works. Good luck

This is probably going to fix it, but just to mention that I was on the correct CSC and I still had to do a factory reset for LTE to become available (go figure).

My device already has the firmware you mentioned ... but no LTE/WCDMA/GSM option visible ... So I had to use *#0011# to select the preferred network mode to GWL through the service menu ..

USSD Codes not Working Anymore

I have my S7 Edge for a month now , everything used to work fine (located in Pakistan)
Two days back I flashed a new Stock Rom from UK to check country restricted apps (there were not much though) and I noticed on that ROM USSD codes were not working and neither do my sensors.
Now I reverted back to stock rom of my region, now the sensors are fine, but USSD codes are still not working. I tried the 2 ROM available for my region thrice, but still the same issue.
Please suggest what should I do?
Note: I didn't root my phone (because don't want to void my warranty since I paid extra $150 for that) nor do there's any network restriction on USSD.

You need to change your CSC to any other region or country.
The UK CSC no longer allows using the USSD codes.
I had the same problem using USSD so I just changed to a different CSC.
Once I changed to a different CSC the USSD codes worked perfectly.

When don't you stop thinking that all people ROOT their phones?
"TWRP flashable CSC's": so you phone has to be rooted! Not everyone wants their phones to root, and there are people who won't want the KNOX-flag triggered!

After giving it a lot of thought you're right, perhaps that's the first thing I should ask,
maybe the reason I did not think of asking is because I come from a rooted family...
But sooner or later doesn't everyone root their phones? LOL

The root method does NOT trip knox! Stop spreading your nonsense lol! It is done with the Samsung official engineering bootloader. Again, WARRANTY VOID: 0x0 :good::good:
I have been flashing/testing different carrier's firmware and have rooted the phone pictured below 3 or 4 times now and, as you can see, it's golden. Currently it is G935U but originally it was from Sprint.

hi,
i have the same problem on my galaxy s7 SM-G930 F
NONE of the ussd/mmi codes work!
when i type the code nothing happens
i instaled the PhoneINFO app and in the CSC Code card the Original CSC Code field is empty
but all other fields are filled:
Product code:
sm2g930fzsadhr
original csc code:
firmwares csc code:
DHR
Active csc code:
DHR
Availabile csc codes:
CRO, DHR
CSC Country:

how can i fix my s7 so CSC Codes can work again!

How to fix invalid MMI code on samsung galaxy s7
I have the same problem on my galaxy s7 SM-G930F.
When I check Divert if Unavailable (62) using *#62# I get the error
"Connection problem or invalid MMI code."...
It turns out that the G930F (BNIB sealed) I bought was a grey import and even though the hardware G930F is international, the firmware loaded is for the UK and the Phone INFO app shows the CSC to be "BTU" (see CSC codes) . And so even though the phone is unlocked, it does not function 100% in the Australian mobile network.
To fix this I had to flash the AU firmware for the CSC code XSA found at
SM-G930F — Galaxy S7 firmware
using ODIN.
After this the CSC is updated to XSA and all USSD codes work perfectly!
No rooting required!
A bonus for having the correct CSC/firmware for my S7 is that VoLTE now works with the carrier!

Just Google SIM unlock galaxy s8 there's tons of sites out there. Prices vary from one site to the next. Once you've got your code enter this in dialer app #7465625*638*# you'll get this screen. Doing it this way you won't need another SIM card to unlock your phone just input your code and hit okay

Hiya did this on my S8 yesterday and works -
1. Download Shortcut Master from app store (Light version works, but it's a great app, support the dev if you can)
2. Open the app and go to the menu (three dot's top right) and select app explorer
3. Scroll down to IMS Settings and select it.
4. Scroll down to ImsSettingsLauncherActivity (last item on my list) select it and hit launch.
5. Select IMS Service Switch and under that turn on everything on that screen. (For me most things (especially RCS items) were disabled by default, but when I looked at a friends S8+ settings they were all on so I tried that and all works now.)
6. Make video calls!

Unfortunately, i have Bad news of this VoLTE enable instruction.
From latest G955F Oreo (Android 8.0) update, (G950FXXU1CRAP)
Samsung blocked ImsSetting activity like below screenshot. It need to additional system or Super user permission.
I don't understand why Samsung block this activity. Its very useful UI activity for us.
We should find another method for enable Volte related function.
