Mobile data stops working - Galaxy Note 3 Q&A, Help & Troubleshooting

Hi. I have the N-9005 LTE version and randomly my data stops working. I can only see the up green arrow but no activity on the down orange arrow. There are no outages with my provider and data works fine on my tablet. In fact, rebooting the Note 3 gets the mobile data working again but it would stop working after a few hours or whenever. Anybody knows something about this? I don't want to do a factory reset again. I've already done this once when my calls had stopped working. I have a 3GB plan and yes my bills are all paid. I checked my APN as well and it's fine. It works when it does but randomly stops working. Any help appreciated.

This will not fix things but will help in diagnosing stuff:
*#1234# then check if there is any newer firmware for your N9005.

No, that looks like a good version, at this point you might need to look into other threads that talk about LTE signal (not only here but possibly in all the other Note3 forums and maybe even in S4 forums). Or hope that somebody that had the same problem stumbles upon this thread and posts more details.
Possibly also some info on the problem could be related to your carrier?

[Q] Not registered on Network Please help

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

SM-N900 Modem/ CSC Country question

I had purchased an unlocked sm-n900 because I figured it might be what would work best with my carrier ( Straight Talk) here in the US. Ive had it for a little less than a month now and have had constant connection issues. Today I saw a thread http://forum.xda-developers.com/showthread.php?t=2475714 In here it is mentioned that
Choosing right modem can make a huge difference as it affects reception, data speed, stability, battery life etc.

So I figured I should investigate flashing a new modem and maybe thatll help my situation. The thing is while looking at my phones info I found out the CSC country is Argentina. Does this matter at all? Is this leading to the problems with my phone or is this from the ROM i flashed (CriskeloRom Note III V05) Im just fed up with the constant connection problems and the constant having my phone go into emergency only mode. Where do I go from here? Do I need to flash a different modem, or an entirely different rom? I dont even know if I can flash any of those modems /: Heres some more info I have Latest firmware info

1. Make a backup of your data and factory reset your device (Settings - User and backup - Backup and reset - Factory data reset - Reset device - Delete all). Take a look if you have wifi. Go to next step if not.
2. Reflash this firmware through ODIN. Dial *#1234# when the process finish and tell me what appears (It will be better if you can add one screenshot)
I am very sorry. .. I just checked it again.. it actually appears as u say. .here I am attaching a screen shot....

Signal unstable one bar or no coverage

Hi guys,
It's been a while since I've been having weak or no signal (one bar or maximum two everywhere all the time), the funny thing is showing the coverage bars even when there's no sim !
Below are attachments of informations for device. Thanks in advance.

The firmware that you are using is a leak and the baseband is of android 4.4.2. It's normal that your phone is a lil bit crazy. Install this APP and add some screenshots for avoid problems and I will tell ya what firmware you have to flash via ODIN.
A device always shows coverage bars without a SIM. It's the Emergency Network. 112, 999, 911 or whatever your local equivalent is, you don't need a SIM to call the Emergency number.
Switch to GSM only mode. Sometimes in areas where coverage is weak LTE/Automatic mode doesn't work well.

Your IMEI is your phone's equivalent of a social security number, NEVER share it with the public.

You will have to flash one android Lollipop Firmware coz your bootloader is updated. Your CSC (country code) is BTU (UK) but doesn't have android 5.0 still. I recommend you flash this firmware for example via ODIN. Good luck and tell me how it worked for ya. Remember dial *#1234# when the flashing process finish and have to appear:

[Q] Weak Signal, Unstable reception, dropped calles

Hi All, nice to meet you all here. I came from Malaysia and i facing some problem with my N9005 - Samsung Note 3 LTE and hopefully can get some helps from here. It was actually a second hand phone but with perfect exterior condition, with Samsung warranty seal to prove that never been repair before or a recon phone. Below are the problem that i realize within this few days
1. Phone have signal, but sometime unable to call in or call out, especially on low battery status (50%-30%)
2. During a phone call, receiving party always unable to hear me, sometime they will hear some strange sound and dropped call, but from my side I can hear them very clearly
3. Always changing network mode. For example 4G to HSPA+ to HSPA to EDGE to No Service
4. When phone was inside a indoor room, very poor signal & unstable, internet speed also very slow or even unable to connect. But when I walk out from the room its become better
Remark:
1. Using Lollipop 5.0
2. Have changed a brand new Sim Card
3. Have tried to move my sim card to other phone, work perfectly
4. Have tried to use other sim card, but same problem remain

I don't need IMEI atm. Well the problem here is that the person who owned the device before you, flashed a Philippines (Globe) firmware on your device. You have weak signal, weird sound, etc for that reason.
Your phone is original unlocked of Malaysia (XME) but still without Lollipop firmware. You can check it: HERE.
* SOLUTION: All zones close yours (Philippines, Thailand, etc) still without Lollipop update. You will void your warranty if you downgrade your device to android 4.4.2. Here we go:
1. I recommend you flash the Slovakia (TMS) firmware via ODIN then coz it has the Lollipop update (like in pic attached). This won't void your warranty either.
2. Dial *#1234# when the process of flash finish and have to appear this. Reflash the same firmware if not:
AP: N9005XXUGBOD6
CP: ?
CSC: N9005TMSGBOE1
3. Wait latest firmware updates of Malaysia (XME) and flash them via ODIN for receive future OTA updates too.
Hi Joku1981, thanks so much for your reply. Since the phone was actually out of warranty period, so i tried to flash back with Malaysia (XME) version of 4.4.2 kitkat (PDA: N9005XXUGNI4, CSC: N9005OLBGNL1).
But unfortunately, the result still the same. Am i missed any important step?

leutzu, i has been tried to flash a few times with new firmware but it's still remain the same problem. I have also sent it to Samsung dealer for checking and they said probably on hardware problem. So end up to save up my time and cost, i decided to bought a new Note4 SM-N910C.
I end up sending it to Samsung, and they replaced motherboard, battery, and updated the soft.
Now it's working fine
