[AT&T Galaxy Note 3 General] SEB1109:
I have fortunately been without those issues for quite some time. I do have to keep my data connection preference set to the slower 3G speed so I have a good solid connection. If I set it to 4G/LTE, I don't get a good signal in my area. I am sure if I was closer to a 4G tower that would be different.

I'm not sure if it makes a difference, but I am currently using Tweaked ROM.

http://xdaforums.com/note-3-tmobile/development/temp-t2816437

Version 3.95 is the latest and greatest from Dwitherell. I highly recommend it if you like the Samsung features and your using a Note 3 model SM-N900T. The stock kernel is fine. If you want a really great custom kernel, lean Kernel works great with Tweaked as well. The latest versions of lean Kernel (3.11.4) were just released yesterday.

Imoseyon does an AOSP version too, just an FYI in case you wanted to try the CyanogenMod route (which also works well for me on my phone) the latest nightlies are stable enough for everyday use in my experience, just not as long for battery life.

So, I hope some (or any) of this was helpful. If you have any other questions, I would be more than happy to help if I can.

The only other thing I can think for you to check is try using the "Samsung Info" app to make sure that your firmware upgrade was complete.

https://play.google.com/store/apps/...o+app&pcampaignid=APPU_CEZYVMevIYuSyAS0toLYAw

I've read about many users who had trouble getting all of the upgrade to "stick" after a reboot.

Let me know how it goes.

I got your pm, and thought this might benefit someone else on here too. Good kuck
[AT&T Galaxy Note 3 General] gil_happy:
Hello, after reading some of the messages in this thread, I would like to know if anyone has any recommendations or suggestions prior to porting my T-Mobile Galaxy Note 3 handset over to AT&T? Basically I've been with T-Mobile for 10 years, and I'm planning to switch to AT&T. I know that I will need to pay off my Note 3 with T-Mobile before they will provide a permanent unlock for my handset so that I can move over to AT&T.

I previously rooted my handset while on T-Mobile, but after the latest firmware upgrade on their network (4.4.2 - N900TUVUENK3), I did not bother to root my phone. Any suggestions if I should root, downgrade firmware, install customer ROM, etc prior to porting over to AT&T?

Thanks in advance!
[AT&T Galaxy Note 3 General] SEB1109:
I don't believe at&t cares if your handset is rooted or not. They want to make sure it isn't stolen or blacklisted which is one reason they ask for your IMEI. When it is rooted, they won't assist with troubleshooting connection or software issues.

I would recommend waiting until after you are on at&t to flash a custom ROM. Just get set up with your account and make sure you have good service.

As far as if you should root your device or install a custom ROM, that is entirely your choice. There are quite a few excellent ones available.

Whew. Sorry about the long post, I hope you enjoy your note 3 on at&t!

Have a great day!

PS. I don't think you can downgrade your software (baseband).
[AT&T Galaxy Note 3 General] gil_happy:
Thanks for this SEB1109.... I know this question has been asked many, many times (and probably should be asked elsewhere), but any ROMs I should look into? Any recommendations?
[AT&T Galaxy Note 3 General] SEB1109:
If you like touchwiz feel, definitely TweakedN3 v3.95 (http://xdaforums.com/note-3-tmobile/development/temp-t2816437). It is rock solid and better than stock (imho).

If you want lollipop on touchwiz, the ROM I would go for is DomPop (http://xdaforums.com/note-3-tmobile/development/rom-dompop-0-1-3-stock-tw-lollipop-5-0-1-t2988660).

If you are more of an AOSP person, Temasek seems to be the "go-to" person for hlte owners (t-mobile note 3). His 4.4.2 based ROM is here (http://xdaforums.com/showthread.php?t=2687074)

If you want to go for lollipop his current project for our device is here (http://xdaforums.com/galaxy-note-3/development/hlte-spr-vzw-temaseks-unofficial-t2953375).

All of the developers of the ROMs i mentioned are extremely capable and very highly regarded. They are the equivalent of "major rock stars". The android community would not be the same without them. We owe them a huge debt of gratitude.

As you can see, there are many choices, now it is up to you. ☺

(disclaimer: I have only listed ones that I have used, that is not to say there aren't other worthy candidates for you to consider.)

Sorry for another lengthy post....

Have a great night! ?

[AT&T Galaxy Note 3 General] WTF?:
I have been a happy user of AT&T's prepaid service GoPhone using an LG E970 rooted phone with custom ROM.

I live in a strong AT&T LTE area. - band 17 is a MUST HAVE!

I plan to root a new Note 3 and install a custom ROM, like my LG E970 has

am I better off with an unlocked 900A or a 900T or some other model of Note 3 ?

like what would be the pros & cons of 900A vs. 900T - I want this usable in the most remote areas possible, which in this state will most always be AT&T, and I want it to be on LTE as much as possible and none of this getting hot/battery drain business!
[AT&T Galaxy Note 3 General] SEB1109:
If you want to root and "play" with your phone, get the 900T.
[AT&T Galaxy Note 3 General] lilphil:
Help me please!!

I've read through this thread and many others to try to find a solution to my problem. I have a sm900t stock rom, carrier unlocked that i have been using with AT&T service since december of 2013. Well as of a month ago I updated my apps as i always did per the phones notifications and my signal started to just disappear. It has gotten to the point that the signal has permanently gone as i would get the message everytime i go to place a call "Not registered on Network". So i was told by the local phone repair techs to update my phone to the lastest firmwire, which took me from 4.3 to 5.0 and still no signal at all. My Imei is still there as i don't have a null imei and if it helps when I dial *#0011# it yields:

No Service

NETWORK: UNBLOCK

IMEI Certi: PASS

Can you please help me and tell me what's going on and how i can get my phone to function again?!?!? thank you in advance!!
[AT&T Galaxy Note 3 General] allessence:
Sounds like your antenna has gone bad.
[AT&T Galaxy Note 3 General] lilphil:

[AT&T Galaxy Note 3 General] bobkoure:
Good to know.

Got any other ideas got for poor reception (15-25 dBa lower than my ATT note 2, both on StraightTalk/ATT)?

Makes the N900T pretty much useless for me.

I'm on SimKat unlocked, modem is N900TUVUENK3. Same results with preferred networks 2g/3g/LTE. in service mode / phone information, preferred network type is LTE/GSM auto (PRL), radio band is set to automatic (only other choice is EURO band).

I'd start editing PRLs, but that shouldn't matter, as it's a ST/ATT SIM and I'm connecting to ATT (not roaming). But at this point, WTH knows?

I was thinking I might flash a N800A modem as something of a last resort. So much for that. Sigh...

No sir. Going to end up with a nice looking paperweight. If you want to experiment just sell that AT&T phone and pick up a nice used T-Mo version. Many available out there.

From the bottom of my heart!

Thank you a million times over! After approximately 5 hours of research, trial, and failure to connect my daughter's new Samsung Galaxy S6 to the 4G network, I found your instructions for the Straight Talk Sim.

Hi. Noob flasher here. I'm in the Philippines using a network called SUN Cellular and I just got this old Note 3 (T Mobile) from an uncle. Any advice on how I can use the local sim? Thanks! :D
[AT&T Galaxy Note 3 General] Jayster0966:
Is the phone unlocked? If not, that would be the first step. There are many people "locally" that can unlock for you or you can use an online service. (Cellunlocker) for example. Then you can stick in your SIM card and check you APN settings for which settings work best.

[AT&T Galaxy Note 3 General] Dethus:
Noob Here

Thanks for replying so quickly! I came across Cellunlocker but I wasn't sure if they were trustworthy. I'll look them up right now. Follow up question though. If I have it unlocked and install a custom rom, will it revert back to it's original locked state? Sorry for the ignorant question. :confused:
[AT&T Galaxy Note 3 General] Jayster0966:
No, it will not. Once phone is unlocked, it will be for good. You can upgrade firmware, flash diffrent ROMs, etc..

I sent my brother-in-law my N2 & S4 to Manila for him to use and those were unlocked. He has had no issues using them with the local carriers and just had to make sure that APN settings are correct for everything to work properly.

Lately I've been getting random data disconnects accompanied by the notification "Restricted Access Changed, Data Service Is Blocked."

Would this have anything to do with running a T-Mobile phone using AT&T network? I have never had this problem up until the last week. That would be me first instinct as to the source of the issue.
[AT&T Galaxy Note 3 General] les_garten:
How long have you had this ROM?

Changed anything in the last few months?
[AT&T Galaxy Note 3 General] magnumforce2006:
Had the ROM since April. No big changes recently.
[AT&T Galaxy Note 3 General] les_garten:
Probably Network related.

I get some crap occasionally with my ATT Note5

Always throws a chill through you when it happens, but I suspect it is a Network issue.

How often does it happen and for how long?
[AT&T Galaxy Note 3 General] magnumforce2006:
Been happening about every hour or so. Usually blanks out my data for a couple minutes, or until I do an Airplane mode reset (which doesn't always fix it either).

It's not a huge issue, but weird that it just started. You're right though, if all things are equal, must be ATT doing weird ****.
[AT&T Galaxy Note 3 General] les_garten:
Have you tried shutdown >> Wait a minute >> Restart?

How long has this been going on?
[AT&T Galaxy Note 3 General] mircury:

How about this? TMobile White: http://negrielectronics.com/samsung-galaxy-note-3-32gb-lte-t-mobile-unlocked-white.html
[AT&T Galaxy Note 3 General] snovvman:
I can see the confusion re 850Mhz. Negri's site does not list 850 LTE on the T-Mo Note 3. So, in fact, the T-Mo N3 has every frequency that ATT N3 has and more?

I'm getting ready to ditch the ATT N3 and go w/ the T-Mo N3. I read many posts that it is working well. Questions before pulling the trigger: Are there going to be any implications related to modem/radio firmware or anything else that would make the ATT N3 simply work better on the ATT system?

I presume we can later flash ATT's ROM base onto the T-Mo? How about the modem/radio?

Thanks.
[AT&T Galaxy Note 3 General] mircury:
Yes, those bands were taken straight from the box the note 3 comes in. So unless they lied.....

People have been doing this for a year with the S4. If there were any negative effects we would have heard about it.

And no I would NOT flash any AT&T roms on this phone. The base rom will include stuff like the modem and recovery. You don't want that. If AT&T has their way there won't even be any custom rom's for the ATT Note 3. It will be hard enough to get root without access to a custom recovery. If by some chance in the future there is a hacked up way to flash a rom on the ATT note 3 you wouldn't want to do that to your unlocked note 3 anyway.

There are more than enough ATT users on the T-mobile note 3 to support your flashing habit.
[AT&T Galaxy Note 3 General] Limeybastard:
Got my t mobile note 3 just now.

I just joined this site and wanted to thank the persons on this thread as I today purchased a T Mobile Note 3 for use on ATT. If I had not have researched this site then I would have ended up with an ATT one, thank you.
[AT&T Galaxy Note 3 General] mdcarter67:
Negri website now says it will be available on 10-10-2013. I'm trying to contact customer support to make sure. Already called a local T-Mobile store and confirmed they will sell me one off contract for $740. I don't think i can wait any longer, might pay the additional $50 to buy today.
[AT&T Galaxy Note 3 General] wdkingery:
What is that after tax? Used to be $708 on tmobile.com

25.00
[AT&T Galaxy Note 3 General] drmacrofish:
Boo, T mobile is charging 745$ if you get it on a prepaid plan. That totally stinks. You can only get it at the 708$ price if you buy it on a regular contract. That is before taxes. I just walked out of one of their local stores. Came out to 826$ total with taxes and a prepaid plan and 10$ for the SIM card. Too much I think.

Anyone know what T mobile cancellation policy is if you get a monthly plan and then cancel that? Do you get your money back for that month. Like say I get the 50$ plan and then cancel it. Am I out the 50$???
[AT&T Galaxy Note 3 General] mircury:
I went to 2 stores today to check and the first one wouldn't sell me a note 3 unless I got service. The second one was willing to sell me one for $740 plus tax without service. So it really is hit and miss.
[AT&T Galaxy Note 3 General] drmacrofish:
Wish I had one near me that would. I went in one and called another and got no love. Negri is going to take too long now that they are not expecting them in till maybe 10/10.
[AT&T Galaxy Note 3 General] dgfriedl:
My T-mo store (Brier Creek, Raleigh, NC) required that I activate the phone on a plan even though their internal price sheet showed the price at $708 on-contract and $739 "device only." I opted for a post-paid plan so the cost was $708+10(SIM)+$48(tax)=$766. Unlocking costs $25 (still waiting on the code) so my cost today will be $791. Cost out the door at AT&T would have been $774 assuming I could get out the door without paying an activation or upgrade fee.

I plan to cancel my post-paid line as soon as I get my unlock and have the phone working on AT&T. I don't know if they will pro-rate it down to one day, but if not the billing period I was assigned starts on the 6th so I will only have to pay for three days at the most.

[Guide] T-mobile Note 3 on AT&T's Network/Root info/LTE Confirmed

Yeah that sounds like a better way to go than with the prepaid plan like the guy was trying to do with me. I was just reading the TOS for T mobile and it looks like you have 14 days to cancel service where "You remain responsible for all Charges incurred through the date of cancellation. " at least you get the device at a cheaper price. I should have done it that way. I had asked the guy about it there and he was like no that way will cost you more...

Anyone know if you cancel the service will they try to make you give the device back???
[AT&T Galaxy Note 3 General] ekerbuddyeker:
I also want to thank people here. I went out and bought the tmobile device, cellunlockered it and it's purring along nicely. I love it! Just need to root it and personalize it now and remove all the bloat.

What did u end up doing as far as the cell phone plan is concerned?
[AT&T Galaxy Note 3 General] GigDroid:
The stores by me are carrying only 16GB models that will end up costing more than the negri 32GB. WTH?
[AT&T Galaxy Note 3 General] mircury:
Was that looking at the actual device or was it the store's printed material? I'm pretty sure the N900T only comes in 32gb at this point.
[AT&T Galaxy Note 3 General] les_garten:
I don't think there is a 16gb model

Is this a test?
[AT&T Galaxy Note 3 General] Kawaisa:
There's a 16GB model but it's for other international markets such as Hong Kong
[AT&T Galaxy Note 3 General] les_garten:
Ahhhh, ok. It seems that those markets would need twice the memory not half the memory!

Thought you guys in this thread may know this as well as anybody.

I'm selling the ATT to get the TMO.

How well does the ATT phone work on other networks? I'd like to know what regions to advertise it in.
[AT&T Galaxy Note 3 General] petard:
Which one is?

SM-N900T (TMO GN3) has

WCDMA Band 2 1900 MHz (tx and rx)

WCDMA Band 4 1700/2100 MHz (tx/rx)

WCDMA Band 5 850 MHz (tx and rx)

LTE Band 2 1900 MHz (tx and rx)

LTE Band 4 1700/2100 MHz (tx/rx)

LTE Band 5 850 MHz (tx and rx)

LTE Band 17 700 MHz (tx and rx)

The AT&T version (SM-N900A) has WCDMA band 4 disabled in modem and a locked bootloader but otherwise seems identical. WCDMA band 4 isn't used on AT&T but is heavily used by T-Mobile and AT&T is a ***** so they disable it on their Note so that users can't easily take it to TMO. The GN2 could have the TMO radio and NV items flashed to enable WCDMA band 4 but the GN3 is locked so you won't be able to.

And why is LTE band 5 important? No one uses it.

[AT&T Galaxy Note 3 General] codester:
Read through this whole thread and I wanted to confirm something.

When i was on cellunlocker.net it said that I have to activate before i unlock because of the region lock. Does that mean i have to activate the phone with t-mob or can I just unlock then activate at att?

Thanks
[AT&T Galaxy Note 3 General] mircury:
No, you don't have to activate. Also, there isn't a region lock on the 900t only a carrier sim lock. Make sure you select the n900t. The first sim card I put in my phone was the AT&T one. Then I did the unlock.
[AT&T Galaxy Note 3 General] keennay:
It's been a while since I was actively involved around these forums (I was when the Galaxy S2 Skyrocket LTE was released for AT&T).

I do remember that AT&T Android updates for the Galaxy S2 took 2432934040 years to come out after the official release... how sooner would we receive updates for the T-Mobile Note 3? I plan on purchasing this version to use on my AT&T unlimited LTE plan.
[AT&T Galaxy Note 3 General] mehdi_s82:
Thanks to awesome devs on xda, I don't remember ever waiting long to use latest update after it comes out for international versions. You would have to wait for at&t only if you don't want to use any custom roms and such.

Steps to enter unlock code

Hello,

I purchased the Unlock Code from Cellunlocker.net but their instructions are not working. I've gone through all the steps. Can someone tell me the steps they used? I've been searching the forums and the web but I surprisingly can't find help on this. Its frustrating because it seems to be working for everyone else although coming from Sprint I'm new to the SIM world!

Is the correct model of the T-Mobile phone: N900T?

TIA!
[AT&T Galaxy Note 3 General] Vandam500:
Yes, that is the correct Tmobile Note 3. I also purchased an unlock code from them around minutes ago and am waiting for it to arrive. Hopefully it works without any problems.
[AT&T Galaxy Note 3 General] mircury:
Did you get a new SIM card for this? Some people were incorrectly put on the media net plan and it doesn't work. Is it still popping up a place to put the code in? Also how many times have you tried the code. Don't hard lock it.
[AT&T Galaxy Note 3 General] Cheeze[iT]:
Had some issues at first. I needed to go into network search and let it search for a bit then it picked it up. Little worry at first then afterwards it's all good so no worries
[AT&T Galaxy Note 3 General] Capt4Chris:
I used a new AT&T Straight Talk SIM.

Well, I guess it's accepting this SIM now because I can send/receive calls and texts. I just don't remember the unlock code ever being accepted...

Oh well... just need to figure out why I'm not getting any data even after updating APN settings now!
[AT&T Galaxy Note 3 General] mircury:
Straight talk uses a different APN setting. It's on their web site. Ill put it in the guide in a little bit.

edit

Straight Talk APN added to the guide.
[AT&T Galaxy Note 3 General] Capt4Chris:
Oh, I didn't know it was different. Makes sense I guess (SIM noob here). I can look it up but if you can add it, even better!
[AT&T Galaxy Note 3 General] mircury:
Try the one I added and let me know if it works.
[AT&T Galaxy Note 3 General] Vandam500:
Wanted to let everyone know that I successfully unlocked it with cellunlocker.net Everything works perfectly. I followed this guide for the APN info and able to send/receive MMS just fine.

Thanks again!
[AT&T Galaxy Note 3 General] Capt4Chris:
That worked! Thanks so much!!!

BTW, you put the video guide for adding the AT&T APN beneath the Straight Talk instructions.
[AT&T Galaxy Note 3 General] sgtcurry:
I got a new sim earlier and was kicked off of my iPhone data plan. I had them put me on the data pro plan for smart phones, I have HSPA+ working but not LTE. I think I have the APN correct can some one help me?
[AT&T Galaxy Note 3 General] mircury:
You did this right?

"Then go to the home screen menu setting, more networks, mobile networks, network mode and change to LTE/WCDMA/GSM"

Also, AT&T has different sim cards for it seems like everything. I know this because I've spent hours in there with a tablet and a noobie CSR. You might confirm with them that your sim card is LTE compatible. The older ones were not.
