Have you tried switching it to HSDPA ? instead of LTE ? as sounds like your in a dead spot i.e 4G is spotty coverage where you are!

Why cant you exchange the Note 9 ? Samsung offer 2 year warranty with there smartphones ? Ring samsung and tell them Note 8 works fine Note 9 i have no signal ? Have you tried resetting your phone ? and have you tried toggling HSDPA to LTE ? Does make any difference ?
Here the link you need https://www.samsung.com/br/info/contactus/

Sorry, I could not express myself. In the store there is no longer blue, so I said I could not change, I've reset all the settings, I've restored everything that was possible, the oscillation and alternation of the continuous network.

They will have blue Note 9 in stock, if they dont leave it with them,use your Note 8 until they have blue Note 9 in stock the hype is over Samsung have plenty of stock now! Also make video to show them your Note 8 works fine but your Note 9 doesn't. That will give them no reason not to exchange the Galaxy Note 9 for you...

Sounds like you need to add or replace APNs.

The International GALAXY NOTE N7000 DOES NOT SUPPORT T-MOBILE`s 3G bands. Just EDGE, Thats all you will get and nothing more. Only the AT&T Version can work with T-Mobile`s 3G speeds

Yea:/ It sucks they dont just make all the bands in them haha. With the AT&T note you get the BEST of both worlds haha
And one more question - is that issue related only with T-Mobile 3G? Will other providers 3G networks work with that GNote?

Did anyone get LTE to work with T-Mobile so far?

Hello. I've just talked with T-Mobile over one hour trying to make the phone connect to LTE. I've read multiple threads and things about it with very disheartening mixed results. I'm about to pack it and unfortunately send it back to them unless some knight in shining armor can really show me what is going wrong here.
I've tested in multiple ways the speed, the symbol doesn't switch from 4G and the speed barely reaches 10 mb.
Any luck?

I just tested both Nexus 5 that we have in the house and although they seem to connect to LTE, they also have low speed, so I suppose it is a network problem from the company. Let me know in case anyone has anything about it being a consistent problem on the OnePlus 3T though. Thanks.

You probably got the wrong version. Everybody who can't get LTE eventually figures out they got the Chinese or European version NOT the united States version.

Where can I find the definition for US, EU and Chinese versions?
Settings/about phone/ model. You want it to say A3000. Guessing yours does not

If you didn't order from OnePlus.net directly then you got the wrong version. Hopefully you didn't get Craigslist'd

Mmm, I've tested on the other phones again. All of them display LTE, none of them are getting top speeds like they usually do and the model seems to be correct. OnePlus 3T still display as 4G and has the same speed in the same network. Might be a T-Mobile problem.

Yeah, it seems like it. To be honest, I rarely check for LTE connection since I spend most of my days in a big zone with Wi-Fi everywhere. It's usually by train and all and since I don't use Netflix and all it might be a common problem and I never realized (but my old phone very rarely switched from LTE to 4G).
I'll call them about it.
Upgrade to OOS 4.1 see if it helps
Im having speed issues with Tmobile and the op3. My s7e and zuk z2 get 20-40mbps download, the op3 gets less than 1, but 9 mbps upload.
All connected on band 4, something is up...
Update OOS. apparently there were issues with T-Mobile and Carrier aggragation going on early in the phone's life. otherwise I have zero issues. That may solve your problem.
I purchased a midnight black and have been using it for about a week now, I flashed Freedom OS and havent had any LTE issues on T-Mobile
I'm on T-Mobile, model A3000, and mine is displaying the LTE logo and getting great speeds (40mb/s +). Is there anything I can check in my settings that would help you troubleshoot?
I'm with T-Mobile and I have no problems with my OnePlus 3T.
Sent from my ONEPLUS A3000 using XDA-Developers Legacy app
Like others have said, update your OxygenOS first, there have been carrier improvements since the version you're on. My 3T has had zero issues w/ T-Mobile. I get VoLTE and VoWiFi w/ no issues, along with respective LTE speeds.

Hi,
I have an international note 5 N920C the problem is when i use mobile data the phone only shows H+ and no 4G

I dont know about the internati note 5 but good rule of thumb I always tell people, Is to make sure there device is compatible with there carrier. Sometimes lacking one frequency in the radio makes all the diffrence in the world.

Hi,
More or less I have the same problem.
My carrier (in The Netherlands) provides me 4G but the Phone gives met only E or H+ Cellular Data.
After some testing I found out the Phone gives me 4G when I move to a new Antenna area of the Provider. But only when I manually set to 2G/3G/4G (automatic). When I move the Phone to a new Antenna it goed back to E or H+.
It looks like a software issue that does not hold the 2G/3G/4G (automatic) switch.
Untill so far no solution.
Factory reset, wipe cache, safe mode.....no solution.
hi did you just update your phone to latest ver? i had n9208 after i update it it cant connect to 4g anymore while my other phone can connect easily problem didnt exist at lolipop firmware
I have the same problem with my note 5 only 3G and H+ no more 4G Lte , i try with others carriers sims and is the same result , wipe , and reinstall and nothing please help us any body have the same problem?
Thanks

SM-N950F Slow Network Speeds On AT&T

Hey there fellas! I recently purchased an international Galaxy Note 8 to use on AT&T here in the U.S. Everything appears to work fine except the speed of my network. Normally in this area I would be getting LTE speeds around 30-40 up and down. With the Note 8 is displays H+ (which I understand to be LTE, but I may be wrong) and I get around 5-7 down and often less than 1mbps up. Some have suggested setting the preferred network time to LTE/UMTS auto (PRL) which was already selected on my device. Is there anything else I can do to get the proper speeds? Thanks!

On all of my international versions H+ was 3G and 4G was LTE. Depending on the area with 4G I would get 20 - 50 megs down on AT&T. On my 950U1 my settings under #*#*4636*#*# I have TD-SCDMA/CDMA/UMTS selected by default and mine shows LTE and depending on the area up to 100 megs down.
H+ is 3G, or 3.5G for some carriers

Ah, that would explain why my speeds are so slow. Thank you for clearing that up. I attempted to select TD-SCDMA/CDMA/UMTS as my preferred network mode but for whatever reason it will not apply. When I reopen that settings menu it goes back to whatever option was selected prior to that. Do you think it could have something to do with the selected APN? I have ATT Phone as my current APN, but at the store they were trying to use ATT Nextgenphone, which didn't work.

I would do all I could to get the Nextgenphone APN working. It is what I used on all my international phones.
Took the Note 8 into the AT&T store today and swapped out the sim card without any luck. As usual they couldn't provide any help beyond that. I also I can't select TD-SCDMA/CDMA/UMTS as my preferred network type for some reason. I contacted the person I bought the phone from and they claimed they used it on Verizon's LTE network without an issue. Very strange.

Would you mind sharing what your CSC on your Note 8 is? I might end up flashing whatever firmware your phone is using, as mine is currently running a firmware for French phones. Not sure if thats the issue, but its possible.

When your look for the firmware look for 950U1 for AT&T. I would look around for a thread on flashing other regions first just to be safe.

I may be totally off here, but wouldn't that be an issue as the AT&T variant uses a Snapdragon SoC, while my device uses Exynos? Another concern for me would the ability to root as well, which is one of the reasons I decided not to buy an AT&T branded phone. Thanks for your help so far man, I appreciate it!

You are right. There is no AT&T firmware for your phone. Unless they changed something with the Note8 you should still be able to get 4G. I did with my international Note4, Note5, and Xperia Z5 Premium models. My son is using the Note5 with an Exynos processor and gets 4G speeds comparable to LTE speeds in the area.
Had this problem as well way back when I first got my 950F.
There are solutions. But you would need one of 2 things.
1. Get At&t to add your IMEI# TO their database so that they can provision your phone correctly.
2. Get another At&t branded phone's IMEI# that is LTE COMPATIBLE. and call them to provision you phone with that #.
My phone is getting full LTE speeds and VOLTE.
But I had them put in the IMEI# of my older Note 5!( which my wife is currently using)...
Hope this helps.

Thanks for the reply. I called ATT and gave them your suggestion and they claimed that it would not work. They said provisioning my new phone with an IMEI of a different phone would be temporary up to 2-3 weeks. Have you encountered this issue? I'm assuming not, so I'm curious as to how long you've had this fixed. Thanks again man

I'v been using my N8 since it came out with my old N5 imei#
As I said be4 basically 4g LTE. &VoLTE Works.
Wifi calling etc.. no.
AND my wife is using the N5 so basically we have two phones on same account with same imei#!

no internet with calling?

i was ready to get rid of my note 4 for the 9 but now im told that i cant be on the internet at the same time im on a call.. sprint said they are working on it, , but they said the same thing three years go with the note 4. Just wondering if you note 9 users are holding out hope or just accepting that itll always be like this. thanks
AFAIK, it should work on WiFi still. Mobile data not working while on a call is an issue I've had with every mobile phone I've owned, I don't think this is a Note specific issue. If that's enough to stop you upgrading from a Note 4 to a Note 9, stick with the Note 4 lol.

I'm in the UK and have had this on multiple carriers.
I have the Note 9 and have never had this issue on that phone, but on my works A5 I had the issue. The fix should be -
Settings - Connections - Mobile Networks - Network Mode and then ensure 4G (possibly LTE) / 3G / 2G (auto connect) is selected.
This solved my issue. Hope it helps
