[Q] SHV-E300S LTE woes

Hi all
I'm new to LTE and the korean S4 is actually my first ever LTE capable phone I've ever owned.
At first, it was already puzzling that "Automatic" network selection in the SKT hidden menu excludes LTE.
Then to find out that picking "LTE ALL" meant that I could get online at LTE speeds BUT not make and receive calls?
So I did a bit of homework and learned about LTE IMS and LTE CSFB and sort of realised partly what my problem is.
Currently my network does not support IMS so picking "LTE All/only" means I'd have no voice call capabilities at all because it's unable to to use CSFB, because 3G is not connected.
But my real question is, can this be fixed? i.e. with a custom ROM? custom-made hidden menu.apk? phone.apk? or with some direct access ussd code even? (my understanding is- skt hidden menu replaces service mode *#0011#)
I also tried messing around with build.prop and added in "ro.telephony.default_network=8"
and that did squat.
can someone please help?

I have the Korean 320L and have tried everything to get 4G working but to no avail. Used Vodafone and EE sims with various Roms. Would be grateful if someone could advise.

Did you manage to get it to work yet?
I'm considering the d802 but I don't know if this would work with 4g in the UK either, why are we so behind with 4g

Guys have you tried putting in the test code in and changing the bands to lte that's what I did with my hong kong version and it's all good.
Go to Phone, just enter following command,
*#*#4636#*#* (no need to press Green Dial Button after this).
2) Once you enter last *, Testing menu will appear. From that menu,select "Phone Information"
3) Scoll down little and you will see "Set Preferred network type". There is dropdown at this location which shows all the networks.
Just note,This is testing menu. It will show all the options like CDMA/WCDMA, GSM, LTE etc. It does not mean that all the networks are supported.
Just insert LTE sim and change option of preferred network from above list to LTE only and check if that works.

The Verizon version come SIM unlocked but you can't get LTE with any Non-Verizon SIM card. Could the other versions have something similar that's preventing you from getting LTE with another SIM card?

Loss of signal, no WCDMA/LTE, only weak 2G GSM signal - what is wrong?

Hello,
I have a huge problem with my Galaxy S5 SM-G900F. I bought it abroad and when I used it for the first time in my country I saw, that there is a problem with 4G/WCDMA connection. When I put my sim card to the phone and set all the preferences in mobile connection menu to "Auto" there is no possibility to call or to recieve calls (even if i saw signal strength meter showing some marks). I can only recieve and making call when I set "only 2G" option and manually select my network. But signal is also very poor.
What I have checked yet:
1. Other sim also doesn't work good.
2. After *#06# i saw my IMEI and it is the same under the battery and on the box (doesn't start from "00") so i think that it is not missed (efs folder).
3. Change firmware with KIES and ODIN for the other version - no changes. Also flash some other "modem" files with Odin with no success in better signal.
4. When im on the free air the signal strength is even at maximum level, but immidiately after going to my house - there is no signal. I saw also, that when im in the city i can connect with 2G network (only), but when im on a village there is no signal at all (even 2G...)
Do you have any ideas what can be wrong? Is this hardware failure? Maybe something with antenna? What should I do before going to gsm service center? Maybe i should change kernel and try some of the custom roms?
Thank you for your help.
regards
Mario

Maybe there is a region lock? Does the Imei start with 35xxxxxx? Does the S5 support the local 4G bands of your provider? Maybe ask your provider for a new simcard. Correct APN settings applied?

My IMEI starts with "35....". Samsung S5 should be able to connect with WCDMA/4G LTE bands in my country. My sim card was changed about 3 months ago, so it is good - i have checked it in nexus 5 and everything works very well. All APN settings are applied.
How can i check if the phone has region lock? The phone is from UK and now I live in Poland.

You can check on the box. If is has region lock, there will be a warning message printed on the box.
Is there any warning message in the notification bar?
And please check as below:
While the phone is receiving LTE/WCDMA signal, open the Dialer, enter *#0011# --> capture screenshot (1).
Then press Menu > Back entry (not Back key) > Menu > Key Input > Q0 > wait for some seconds... > MAIN MENU > DEBUG SCREEN > NAS INFORMATION > MM INFORMATION --> capture screenshot (2). And then Menu > Back entry MM REJECT CAUSE --> capture screenshot (3).
And post these 3 screenshots.

I was able to connect to wcdma signal (I think) for some minutes. I give you all screenshots.

Is your network Polkomtel?
The error cause is: No suitable cells in location area - This cause is sent to the phone if it requests location updating in a location area where the subscriber, by its subscription, is not allowed to operate, but when it should find another allowed location area in the same network.
So may need to give this information to your network operator and ask them to fix.

So it is not the phone problem? It is my network operator error?
My network is Play P4, but this provider has no transmitters for his own in Poland (or has very few). He is able to use all of transmitters in Poland through the roaming (so teoretically i can connect with Polkomtel, T-Mobile and orange transmitters)

Hi, este you able to fix your problem, ir so can you Please tell me how?

N900S GPRS EDGE Problem

Hi guys,
I just bought a Note 3 (N900S SK Telecom) from Korea which will be used by me in India. I have observed that I get a G icon when i am in 2G mode which should be generally as E (EDGE). The speeds in G are drastically low when compared to E and i get about 2 KB/Sec browsing speed which is absolutely horrendous. Now when i have 3G Reception, i get a maximum of 3 mbps whereas i used to get 7.2 mbps constant in my Note 2. I also get a 3G icon in the top instead of H or H+.
Is there any possible to way to get EDGE and H or H+ speeds in my N900S ?? WIll changing of modems or flashing any other ROM will help?

Anybody knows how to sort out this problem?

Do you use the same SIM and in the same location as when you used your Note 2?
I don't think it's the problem with modem. Most likely it is the problem of the mobile network.
Please follow these steps and show the screenshot: open Dialer, enter *#0011#, Menu, Back menu item, Menu, Key Input, enter Q0 and wait for some seconds...
Then select DEBUG SCREEN > NAS INFORMATION > GMM REJECT CAUSE. Capture screenshot and post it here.
And also check the FIRMWARE INFO section in the Phone INFO ★Samsung★ app.

Here you go. I use Local Network of India and it is not a network issue as my other phones gives a EDGE network support

So if that phone has an unlocked bootloader and all those, why not just flash a different ROM? The latest Hong Kong one for example? Damn that screenshot has hard coded Korean language written!
Damn ignore my comment, didn't notice the model number is N900S!

Looks like all info are normal. Should be a network issue. Or please check your APN settings and make sure all parameters are correct?

I've used Korean S2, S3 and all had same problems. Korean S2 was able to convert to International S2 and that gave me EDGE Connection whereas there was no work around for S3 and now Note 3. Can this phone be installed with some other modem which will give me EDGE?
will n9005 roms be compatible?

AFAIK there are several custom roms for N900S. You can google it.

After sim unlock

This thread is for those who feel brave enough to venture into this settings menu. No, that isnt a challenge, its a warning. Even if you follow these instructions down to the letter, I am not responsible for anything you do to your phone. THIS MENU CONTAINS STUFF THAT CAN HARD BRICK YOUR PHONE!!!!
That being said, heres the reason for this thread. Some of us have ventured into the sim unlocking of our devices for a myriad of reasons. Some of us are planning on using the device on a network that uses LTE bands that Sprint doesnt. That being the case, there are some LTE bands that are disabled by sprint but the phone is still physically capable of connecting to. In order to enable all LTE bands that the phone is physically capable of, you can do the following.
from the dialer, dial
*#0011#
hit the upper right menu button, select key input, and type a capital Q, then ok. then menu again, key input type in 4 zeros "0000" and hit ok. Menu again and hit the back selection, menu again and hit the back selection. It can take up to 30 seconds for it to give you the next menu and you may need to repeat that process, but once the menu is up, make the following selections.
UE SETTING & INFO
SETTING
PROTOCOL
NAS
NETWORK CONTROL
BAND SELECTION
LTE BAND PREFERENCE
LTE ALL
if the LTE band youre trying to use isnt in the list above "LTE ALL", then the phone isnt physically capable of that LTE band, and if you absolutely NEED that missing band, youre going to be best served by getting a different phone made for a carrier that uses said band as its not possible to add LTE bands that the phones physical radios arent capable of connecting to.
