Note 3 Rubbish Signal... wrong modem? help needed - Galaxy Note 3 Q&A, Help & Troubleshooting

Hi, I bought my note 3 in UAE and I am using it in the UK. I am on Vodafone. I always get rubbish signal in my house. It is on "emergency calls only" nearly all the time. Also the LTE/4G has NEVER worked since I got it on launch (Sep). Whenever I turn the 4G on the H+ sign never comes up. Some people may argue that Vodafone is a rubbish network. I agree too but I think I may need to flash a different modem? My model is a SM-9005. Do I need to flash a different modem to get the 4G to work? Thanks

You can actually try a different ROM or maybe a custom ROM? At the same time, reception might just be poor in your house. So you might need to make do with regular 3G or EDGE. I no for a fact that in my friend's house i ALWAYS have to switch to 2G because 3G reception is never available, I have SM-N900 tho.

what if i flash a different rom/modem?
I just checked and vodafone operates 4G/LTE at 800MHz. On the samsung uae website it says that the note 3 supports 800MHz 4G/LTE

ROM's won't make a difference as it's the hardware on the device itself.

I also noticed the note 3 doesnt have a superb signal reception... For example in my house my moms s3 and dads s4 have full bars where i on my note have one bar less than they do. Little dissapointed

Check phone status in settings and compare it with the S3 and S4 - you'll see it's just the bar's that show different the dBm's are what counts. You'll see it'll be identical to the S3/4

The device itself has the bands. But you cannot access them by changing the modem. The N9005 supports many many bands but different MPN Codes on each device limit it to specific countries.
It's all a legal thing. Radio frequencies are controlled, unless the UAE version supports the exact same frequency that your UK carrier runs on it won't work. Upgrade to kitkat and test it.

[Q] *** N9005 on ATT LTE / Rogers LTE ***

Hello,
Has anyone actually tried an N9005 on ATT LTE or Rogers LTE?
Lot's of speculation and indeed online the specs say it should not work. Hopefully there is an ATT or Rogers modem to flash soon.
Thanks,
Kevin

What speculation? It is missing the required bands to work on AT&T.
The hardware has support for it - so its a software restriction. But you're right it has been confirmed that the N9005 stock doesn't work on AT&T / Verizon.
Note II received AWS bands by a modified QCP file. Some people say its just a modem flash.
Yeah I'm wondering the same thing my unlocked n9005 works on Rogers lte but I was hoping there was a modem I could flash since coverage isn't great and I heard it's because of software reasons
Sent from my SM-N9005 using Tapatalk
I am using an n9005 and it works on LTE just fine. Maybe the coverage area is good where I normally use it.
The n9005 will work on Rogers LTE where there is some 2600mhz coverage.

I'm waiting for something to happen on this front as well... I've had my n9005 for about 2 months on at&t and have been settling for hspa+ but it's *really* slow. if anybody has any ideas as to how to get LTE working on the n9005 i'd really like to hear about it.

I've attempted to flash the modems from N900W8 firmwares without success.
Still looking for a way to enable 4G LTE with Telus on the n9005.

You would at least need the AWS band on your device to start thinking that enabling LTE for Telus is feasible...
Your device does not even have this band on 3G...

Both the n9005 and n900w8 have the same hardware. It's just primarily based on software at this point.

Ah okay, gotchaa.
Finally got some LTE action in TX
Hello, I have an sm-n9005 on AT&T (go phone). Been living with HSPA since getting this phone in early April. I'm on vacation in Texas visiting relatives and on the way from Dallas to Houston I actually got 4G in two locations briefly while driving. Oddly, both of these locations were not in Houston or Dallas where one would expect them to be, rather in smaller towns. I don't care what anyone here says about modems, firmwares, etc. They HAVE the capability to serve LTE to these phones but won't. The bottom line is deregulation is killing the consumer while these clowns pretend each one has "the best" or "the most reliable" LTE service.

[Q] Bought the SM-N900 for use in the US, did I mess up?

Basically Ive had the phone for over a month now and the connection issues have been constant. The carrier I use is Straight Talk. I got a new SIM card. Ive tried every APN setting it seems. And I cannot get any help. Did I plainly just mess up and by the wrong version of the phone I needed?

Should have gone for 9005.
When It is on GSM only mode I only get EDGE speed, and when I switch to either WCDMA/GSM or WDCMA only mode, I do get H+ but its not reliable and I frequently end up in emergency calls only mode and am frequently resending messages. What model should I get for the best results with Straight Talk does anyone know?

You need the N900A (AT&T) or the N900T (T-Mobile). GSM Mode means 2.5G (EDGE) only. WCDMA Mode means H+ (3G) only.
You can also try the N9005 if you're into tinkering and whatnot.
Your current phone most likely does not support the recommended 'fast' bands that are on US Carriers.

Do you know which one would be the best one to get? I'm into rooting and flashing Roms, so based on that Im guessing the N9005, but arent there different carrier models of that phone as well /: basically I dont want to make the same mistake

N9005 is most used internationally so more devs support this device. But the N900T also works too.
Not the N900A if you care about ROMs.

Okay then I'll pass on the N900A. Are there specific carrier branded N9005s? or are they all the same and unlocked. Sorry for all the questions. Also I barely figured out how to "thank" you >.<-

Yeah there are, and there are specific models of N9005 too with a different partition structure (Hong Kong 16GB)
You're going to have to find an N9005 not from Hong Kong just in case, even though they also sell the international 32gb version as well, and that is already unlocked SIM wise and region wise.
Also, if you come from the states, make sure the bands are supported by your phone. People have bought the n9005 from America to find the LTE bands don't work in Europe..

[Q] Galaxy Note4 smn910c - Status bar not showing 4G LTE

Hi,
I am using Galaxy Note4 smn910c with carrier Simple Mobile. Status bar never shows $G LTE rather it only shows 4G.
My phone is LTE capable. ANy idea why is it not showing LTE on status bar. I have tried with t-mbile sim also and same thing happends. No LTE.
Please suggest.
Any one ? Please suggest.
910C is not LTE for USA, no ?
its for asia / korea.
It is lte calable as per the specification. It supports most of the lte bands.

Buddy, LTE and 4G is the same! 4th generation mobile network. If you've rooted your phone it's easy, just install gravity box and switch to LTE icon, done. It's just the icon, if it shows 4G your're connected to a LTE network!
Comprehensive list of ROMs for N910C?
Does anyone know of a site or thread that lists all of the available ROMs for the SM-N910C? The Phone INFO Samsung app shows it has a UAE ROM, but the default language on first boot is UK English. I'm having the same weird issues with the connectivity icon, and it would be nice to try some different regional firmwares.

what firmware should I download for vietnam?

Hi all,
I just got a snapdragon SM-N910F and flashed some custom roms onto it but the reception has been really bad so I want to flash back to stock and see if the region/csc, etc. makes a difference. However, when I flashed custom, I didn't jot down what region/csc it originally was. so I downloaded an app and it says the phone was made in Vietnam. so if someone can tell me which firmware I need for Vietnam, that would be great.
thank you in advance.
The firmwares are interchangeable, you can use any firmware made for N910F model. Also the phone is made in Vietnam, doesn't mean you need a Vietnamese ROM to run on it.

ok thank you. then I guess this phone just has bad reception. I've tried several stock and custom roms and all had very bad reception as I have only 0 to 1 bar of signal. whereas my Note 3 SM-N9005 always has 4 to 5 bars.

Nope, reception is fine on my end, as good as Note 3, if not better, and the call quality is immaculate, that's the best part.
And on XDA hit the THANKS metre, saying thanks doesn't mean much here :laugh:

what carrier are you using this with? I have t-mobile, but of course it depends where I am from the towers, etc. too; however, with my Note 3 and t-mobile I always get 4 to 5 bars.

I am in India mate, using Vodafone India. Four bars is like always for me, and other time 5 bars, obviously not when I go through a subway or anything, but most times its more than fine.

Cellular strength and throughput

We know how much you like to stream, ahem, "videos", and so cellular data is mega-important. Rate this thread to express how you think the Samsung Galaxy S10's LTE performs. A higher rating indicates that it's fantastic: throughput is excellent and signal strength is top-notch.
Then, drop a comment if you have anything to add.
Not as good as my Moro Z Play for picking up signal in. At work most of the times I get 1 or if I'm lucky 2 bars.
The S10 (Exynos) cannot hold on to a 4G data, while the Moto Z can
Tried two different networks (O2 and Vodafone), same result
Even iPhones (seen lots of people with 7/7+) have no trouble
Keep interrupting phone calls whenever the signal is not good (worse than an S7)
4G will randomly stop working even does it displays 4G+ wit full bars.
I'd have to restart te phone to solve the problem
4G/LTE on S10+ Exynos working better than Note9 Exynos on US T-mobile. No issues so far.
Working great. Good speed results on AT&T 5GE

Thanks for the reply. Yeah I'm at -120ish so basically no service whereas my s7 was closer to -90. I'm also using the TPA CSC and assumed that was the problem but maybe not. I'm tempted to flash an unlocked US firmware.

I think BTU UK unlocked should be a good start. Factory reset may also help. I'd also try different SIM card to see if that bad signal issue is limited to the SIM or T-mobile
You should also check if you live in area that has band 71 primary coverage as that is not supported on this model

I haven't tried a factory reset but T-Mobile did give me a new sim to see if that'd fix it. I checked me local coverage and I have all the bands for my area so I'll try a factory reset and maybe different firmware. BTU didn't show up on sammobile btw, but I may try the "unknown" one.
I think Exynos has multi CSC firmware and the active CSC gets decided on which SIM you put in after factory reset. But since you're on T-MOBILE USA it'll default to original CSC

Same here with Snapdragon S10 in Hong Kong.
I have s10e and after the security update of 1st April I am facing issue with the network. It's like when the network setting are on lte/3g/2g , then only 4g is working with no network for calling, it shows not registered on network. If i change it to 3g/2g then there is no 4g signal, but calling is possible. It was not there before the update.
I am using Airtel (in India)
for best signal, you need Mi9 (the flagship of the year), have both so yeah, Samsung shows very few bars in the same locations.
