Tmobile Note 4 on At&t losing lte - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

So I put my SIM in from my g3 (which was T-Mobile and getting great lte) and phone was working fine then for some reason reverts to 4g and no lte. Check my account online and my phones imei shows up as an old blackberry which downgrades my plan automatically.
I can stick SIM back in old phone get lte, switch again and it reverts. Called and customer service can't seem to help. Anyone else with T-Mobile note on att having issues ?

I have been having a different issue. Every couple of days, I would loose all T network connection as the APN "ATT Phone" would become unselected for a as of yet undetermined reason. If I select it, everything works just fine (include LTE) till it unselects itself a day or two later. I cannot determine the cause.
If I look on my account it shown some "dumb" phone whereas I used to have a Note 2. I do get LTE. I use these APN setting, which seem to show up as default when I press the reset on the APN menu:
Name ATT Phone
APN phone
Proxy Not set
Port Not set
Username Not set
Password Not set
Server Not set
MMSC http://mmsc.mobile.att.net

See if these are the setting your SIM selects. If not, you can try unselecting "ATT Phone", change it and select it after saving. But perhaps you need a new SIM which T should be happy to give (or maybe it is a couple of $) you if you visit a store and say you lost your phone and the sim.

Thanks for the input. Yes I have tried deleting apn settings and adding the ones like you listed. It didn't help. Get 4g but no lte. Went to att they pretty much just said too bad it's not our problem cause it's a T-Mobile phone.

So far no issues running it in Manhattan for a couple weeks - I can't tell the difference between this, my OnePlus One, and my old AT&T Note 3 - all using the same AT&T SIM.
I did get some slow data speeds while in Williamsburg last weekend, but my wife's AT&T iPhone 6 had the same issues so I don't think it was a phone issue.

Oh okay. I don't know why mine is having this issue. Have used several T-Mobile phones on att without issue

Sorry to say it appears the Note 4 is polled or "phones home" and immediately shows it's non-approved IMEI. When I change the SIM from my T-Mobile Note 4 to my ATT Note 2 the MyATT page almost instantly changes from BlackBerry7100 to "Smartphone". Not sure what to do because it'll surely cost my LTE speed.

I've been using a T-Mobile Note 4 on AT&T since the week it launched without these problems. I have a feeling I'm jinxing myself or that it's only a matter of time before it does happen. What's weird to me is that on the AT&T page it shows I still have my old LG G3.
Are you guys using custom ROMS or Kernels or anything? I have pretty much rooted from day one and froze a bunch of stuff and immediately got rid of the Carrier IQ.

Well let me chime in. I never got lte on the note 4 until I got tired of slower speeds haha. I had an iPhone so I went to at$t to get another sim card but brought my s3 so they wouldn't know of the note 4. Problem I think was putting it straight into the note 4 and not settle into the s3 first and get all required info. So I was without LTE for a while until I decided to try again for it. So I called at$t and told them I was not getting LTE on my phone 5s so they changed the imei # to the one for the 5s. Still didn't get any lte so I went to an at$t store when they said to pick up a new sim. I used the iPhone probably for about an hour and got LTE. So from that point I put the nano sim into the note 4 and now I've been getting lte for over two weeks and great signal coverage. On my account it says I'm using a dumb phone but when I go into upgrade options it says I'm on an iPhone 5s.

HTC One 64GB Developer Edition signal strength

I just received a Developer Edition 64GB HTC One. I also have in my possession the AT&T Store model. I was receiving 2 to 3 bars signal strength at home with the AT&T version, but when I started using the Developer model, I was receiving one bar.
Also noticed with the developer edition, I was moving between HSPA+ and LTE frequently and even lost signal when I went inside a store. Is there anything I can do to fix this? Is anyone having the same problem?
I don't want to return the Developer edition but signal strength is important to me and I may have to, if it comes down to it.
Bump
I am by no means the most knowledgeable person here but I was for many years an employee of at&t and in that role was part of group of people that tested pre-release devices as well as upgrades to those devices post release...
So with that I know that at&t is known to manipulate signal meters on the OS of devices as part of their "network optimization". So what that would mean is that the signal strength measurement of a device with non-at&t OS might show that -95dBm is one bar, the same device with the at&t branded OS would show two or three bars. Leading the consumer to think that they have better coverage than they do.
I am not suggesting this is for certain the case but you can probably find a reliable signal strength tool for free in the play store and load it on both and compare the actual dBm measurement and you may find that they are close to the same and that the signal meter is not as accurate.

Edit: I downloaded Network Signal Info by Kaibits Software and it seems to have a lot of useful info.

Ive never worked for AT&T but this is very true. As someone who always has the latest phones (me) its very apparent when you go to CM or any other non carrier ROM that you notice how they manipulate the signal meter.
The real answer here is that there is no difference in reception, only in signal bar representation. I believe the developer edition has a bug because the range represented isn't quite correct, it bottoms out at -113 dBm while 10 MHz LTE like on ATT should bottom out at -125 dBm.
Same situation but signal is in fact lower.
I actually found this posting searching for this exact problem. I have the ATT and the Developer edition. I noticed the bar difference but as everyone has been alluding to, I just wrote it off as how signal displayed as being wrong. However, when I turned the WiFi off and was trying to use the mobile media only, it was so slow to non existent in LTE but it changed to non LTE and did have some throughput but as you experienced it kept changing around. Again, the ATT version had great throughput and speed and stayed solidly on LTE. I am sorry I do not have the solution as I am also trying to find out what is going on and as you, I do not want to return the unlocked phone. Hope we find the solution soon.

Did ATT have different APN on the One? They have changed APN many time before. I have the dev edition with a LTE sim(one come from an ATT LTE phone), can some one post the APN from a ATT One?
Thanks,

I have both the ATT and Dev editions. The apn settings that the dev auto populates are the same as the ATT apn settings. I did go to speedtest.net on both phones (using LTE in Virginia Beach). Although the ATT One did have one test with DL speed of @21 mpbs, subsequent tests were @ 5mpbs, which were the same as the Dev One.

FYI: I also ran Network Signal Info app which showed both devices picking up same signal (-85dbm), but each had different number of bars (ATT One had 4, Dev One had 2)
I have the same problem in Massachusetts. I have both phones At&t and dev. The dev can barely keep an LTE signal. The At&t is fine. Any thoughts on how to extract the radio from the At&t model and flash it on the dev model?

hmm, that's what I have. I am in NYC this week and the LTE IS pretty fast. 16mb d/l
Sent from my HTC One using xda app-developers app
No need for an app. Go to Settings > About > Network. Compare the dBm there. I am getting great LTE on my unlocked edition. Got 37 Mbps down, 18 up when I tested yesterday.
-105dBm
8.33 up
6.57 down
inside my house with ATT LTE
I work in a large office building and my previous phones had a very difficult time holding an AT&T signal.
The worse for me was the Nexus 4. Up until yesterday, I was using the Samsung S3 and it did quite a bit better.
The HTC One is doing a FANTASTIC job for me. Much better reception and 2 or 3 dBm better than the S3.
So far, no complaints.
This is making me feel a bit uneasy... I hope I don't have any problems with mine! Glad to know people are aware of it, I guess...

The signal strength is the same on both devices I have (ATT and Dev). The only difference is the way it's presented or each device's interpretation of a "good signal".
Some people were saying they have the AT&T and Developer edition and the Developer one actually dropped connections where the AT&T one held strong and was very fast. That is what scares me.
I want to make sure people are not getting caught up with signal levels in dB. I have personally spent a good amount of time testing both phones. There is several times that the DEv unit was not operating in LTE frequencies and the At&t unit was working perfectly. So I called HTC to complain. I would like everyone else to complain to HTC. They are blowing this off. There needs to be as many complaints to get this escalated. Please do not dispair about complaining to HTC thinking your phone is OK.
I had both phones for a day and, while I didn't compare signal strength (only one sim), I haven't noticed my Developer edition having any issues with signal since I took my AT&T model back.
Speeds are right where they should be and I have had no dropped calls. Maybe it's a placebo effect.
I have to say, though, even if I knew for a fact that the AT&T model consistently got better reception, I would still choose the Developer edition for the lack of bloatware, wireless tether, and factory unlocked bootloader.
We're bound to get a firmware update eventually that includes a new radio. I'm sure it will get better. Assuming that it's worse, I seriously doubt that it's hardware.

Stop spreading your lies, Walternate, or we'll take out a chunk of your brain!
My developer edition is pulling down 43.6 down and 12.8 up inside the house on AT&T LTE. Current signal strength is -81 RSRP and -7 RSRQ.
I had a problem with the Dev edition not working properly with my AT&T SIM card yesterday when the phone arrived. All the phone functions worked fine, but Data did not work at all. It gave me a message that the APN was configured wrong. (Even though it was the stock AT&T settings.)
I stopped at my local AT&T Corp store this afternoon while I was out and they swapped me into a new LTE SIM Card for free. They also checked my IMEI and I believe they added it to my account info. A quick reboot and things were working fine and flying along. Apparently some of the SIM Cards are set up for the HSPA + "4g" network and do not have something authorized for the LTE. Both my old SIM Card and the new LTE card looked exactly the same as well, so there doesn't seem to be an easy way to tell if you have the LTE Enabled card. (Obviously if you were using it with an LTE phone before you know.) I was using a Nexus 4 prior to getting my One so HSPA+ was all I had available before.

You didn't need to give AT&T your IMEI. In fact, I try to avoid this with unlocked phones. You did, however, need an LTE Sim card to get the full benefit. You could have used your old card, but you would have had to enter a different APN manually and then you would only get HSPA speeds, which would be a shame.

AT&T APN Settings for LTE

Anyone else on AT&T unable to get LTE? The APN settings that auto-downloaded are correct according to AT&T's documentation, but I'm only getting H+.
Your GPRS could be disconnected. I'd you use app advanced signal status you can look at settings Beyer to see if your set up correctly
MasterBrick SCH-I545 Galaxy S4, XdA mobile app...
I had to use my girlfriends IMEI for her Nexus 5 for it to pick up LTE. Before that, I was only getting H+. Try to get an IMEI of another ATT LTE Android phone and it should do the trick!
Can't get LTE to work
I need some help. I have the new, unlocked, Sony Xperia Z3 Compact and I can't get on the AT&T LTE network as well. Here are the steps I have taken:
The Setup
I have a Samsung Galaxy S4 that is on the LTE network with no problem
My AT&T account had a Lumia 820 device tied to my account (and old device of mine) and it worked fine for LTE on all of my future pones, including my S4
I purchased an unlocked D5803 Z3c from Handtec
My Activate Attempt
Went to the AT&T store to pick up a new nano sim card
I gave my new (Sony) IMEI number to the AT&T rep (stupid move, clearly) and they loaded it under my account
With the new sim, my Z3c could place calls and send/receive text messages
Data would not work
My Resolution Steps
I looked up APN settings online and tried several different variations
The HSPA+ Cingular APN settings worked, but left me without LTE service
I could not get the mobile.att.net APN and LTE settings to work
Reading Android Central and XDA, I discovered that others had this issue as well
Using forum advice, I called AT&T
The AT&T rep did confirm that my Sony IMEI number was registering as a "2G" phone, which is why I did not get LTE access
I put one of my extra LTE device IMEI numbers on my account
My phone still won't connect to the LTE network
I notice that even though they registered an LTE phone (and they confirmed it came up LTE), my AT&T account page shows an old flip phone silhouette
The rep noted that there was nothing else they can do...so I basically have to deal with it
I'm posting on XDA to leverage the wisdom of this crowd
I remain confident that this will get resolved, yet frustrated at the same time
I'm at a loss and wonder if I have to activate this nano sim in another supporting device or the like. Thoughts?
Thanks in advance for your help.
No clue, but AT&T tech support confirmed that my IMEI is registered and my previous two devices were all LTE devices. I have no idea what's going on either.

Are you having the same issue? Do you see the cartoon sketch of a flip phone in your account as well?
What you have to do is give them the imei of an LTE capable phone. It absolutely does not matter that you will not actually be using that phone.
If you already have an LTE phone, just switch your SIM to your z3 when it arrives. It is absolutely unnecessary to call AT&T with your new IMEI. Anything AT&T tells you to the contrary is flat out wrong.
Issue resolved!
Bottom line...do not give these clowns your Xperia IMEI number.
When they entered the IMEI number it flipped my data plan from a grandfathered unlimited plan to a pay-per-use plan with no LTE (why they couldn't figures this out last night, it beats me). He was talking about my wife's plan and her unlimited data. I then noted "mine is unlimited too" and then said it wasn't. You can only imagine how things went from there.
The unrecognized IMEI number automatically switched me off of my plan.
They have me on a temporary 3GB plan, as the support rep couldn't get me back on the unlimited plan. They have to send the change to their back office team and it will take a week to get it back.
My phone now has the 4G icon versus H+.

Nope, it actually still shows my previous LTE-capable phone.
I actually also initially had this issue ; I was sitting in the AT&T &T store on the phone with tech support until the sales rep realized my phone wasn't showing up in the system as an LTE device. He input a bogus LTE IMEI for me, after which I restarted my phone. It's been working for me since then
Whelp, I guess I'll go to the AT&T store again later, then.
So everything that is claiming to have LTE ----> Do you have a 4G icon on your phone or LTE? I am in US, went to ATT store ---they entered an imei of a Samsung Galaxy S5 and now it shows 4G. If you go into mobile networks preferred network mode it says 4G preferred/wcdma/gsm. I am assuming this is just due to the UK software version not being the same as US...

IMEI problem rectified, they reverted it to my previous phone's IMEI. Now displaying 4G. Sweeeeeetness.
It's just silly that AT&Ts LTE is tied to the IMEI in their system and not simply having an LTE capable phone.
I ported a line to use with my Z3c and gave them the IMEI of an AT&T HTC One so that LTE would work, but they would only send me a micro sim because according to the IMEI that's the sim I need. Tried to tell them I need a nano sim but the gal on the phone said she couldn't send one, I'd have to go to a store pick one up.
If you are going from an LTE phone that uses a nano SIM card to the Sony Xperia Z3 compact, it is not necessary to contact AT&T. You will need to manually add the APN settings on your Sony Xperia Z3 compact. Here is the path to get to the APN settings..
Settings > More > Mobile networks > Access Point Names > press + to add a new APN
Enter in the following settings listed below

Save the changes you made, select the APN you just created and reboot the phone. Everything should be working from there.
Here is where I got the information from: http://www.att.com/esupport/article.jsp?sid=KB424489&cv=820&_requestid=838329#fbid=ecLfo9YLvXa
So I do have the 4g icon in my status bar. Does this mean that LTE is working fine?
The only reason I am asking is because on the MY ATT page I do only see the silhouette of a flip phone.
Edit: My phone automatically downloaded internet and MMS settings when I first booted it up. Is this what others are doing?

Yes, you are getting LTE on your phone
LTE = 4G in Europe
4G = H+ in Europe
3G
etc
If you do a speed test, you will see that you are getting LTE speeds on your phone
Problem here too. I just went in to get a nano sim. The guy hooked up my number from a note 2. Does not show data. He said I needed to put in my IMEI number from the box. I didn't from recommendations on here. The problem is that I didnt have a rebutle sp? Because I really don't know how it works. He said if my note 2 was lte, it should work. I don't know what the heck to do

AT&T and LTE?

Anyone using LTE on the Nexus 6 with AT&T? Mine from Motorola came today. I'm just getting HSPA though. When I try to select preferred network LTE, the button is filled but the text doesn't say lte. Previous phone was the 6 Plus. Any help? Talked to AT&T and they added the phone but no worky!

I have the same issue, except I was not able to even select LTE before calling the tech support.
The tech support has confirmed my data plan and APN setting are correct.
Can it be like the tech support said it might be the sim card? Or my APN setting is actually incorrect?
Anyone has solution for this issue?
If someone with LTE can post his/her APN setting, I'd be really thankful.

Thanks a lot! It does allow me to use LTE.
I found out my phone switched to LTE couple minutes after I post the reply.
I had another APN setting, and it also works with the setting you provided.
So the key here is to talk to a knowledgeable tech support, and confirm your plan, IMEI, and APN setting is correct on his/her end.
The tech support mentioned my device displayed on his end was not Nexus 6, so I provided him with my IMEI, and that is probably why I was able to select LTE for my prefer network.
I'm on AT&T with an AT&T preordered 32GB. I've got my grandfathered unlimited LTE (according to the tech support chat dude) and the IMEI matches his database. I'm still only getting on average 1-3Mbps down and .02-1Mbps up.
I've double checked APN settings, tried the old "phone" APN settings, spoke with chat who advised me to try a new SIM or exchange the phone, reboots and all. I'm pretty much in DC, so coverage should be a non-issue. I've got full bars and the indicator shows "LTE". I'm at a loss and was wondering if anyone on here had any bright ideas?
I have AT&T, but purchased my unit at T-Mobile. I switched sim cards out the box, and had LTE with no issues.
Have no problems with mine (and yes, mine is a freshly rooted AT&T model Nex6--yes, you can oem unlock and root it just fine).
Of course, I also live in one of those parts of the country where the Deathstar Telco tends to have the best coverage so there's that; I'd be shocked if I DIDN'T get LTE around here
(Which is rather more than I can say for Sprint around here, but that's neither here nor there)

[Q] Straight Tall APN issue with SM-910T

So I recently got a T-Mobile Samsung Galaxy Note 4. As we know, it's unlocked 100% without any special root methods or entering in codes into the dial pad. With that being said, I popped in an LTE Straight Talk SIM card, transferred my old number to the new SIM and configured the APN and for a long while it was working fine with no issues. Then out of the blue, I had no data. It absolutely quit without warning. I go to check the APN settings I had previously and they were gone. I had redone everything and saved the settings. However, when I go back out a menu, no Straight Talk APN. I did the same thing again....and once again no APN settings. Just the default T-Mobile LTE APN.
So I'm at a loss. It was working fine previously and now I cannot set APN settings. I have reset the phone more than once (reluctantly). Any thoughts? Any help would be appreciated since I'm paying those bastards $45 and some change a month for service I cannot get. Also as a note, I can receive and send text messages with no problem. Calling number results in "you are not registered on a network," but I know the fix for that.

Try setting the APN with this app https://play.google.com/store/apps/details?id=com.tracfone.straighttalk.stdatasettings
Sounds like your phone got black listed. Did you buy it from Tmobile? If you bought it from some one else it was either a stolen phone or the previous own stopped paying for it.

I had bought the phone from a local gas station owner (who had 2 other T-Mobile phones with him). It was working while he showed me the phone (he had gotten several text message and Facebook updates). He then reset it. I bought a Straight Talk SIM kit and went to work. I had working data until the next day. I had played around with some more internal settings, like updating the touch sensitivity and more. Everything was working until I refreshed the Wi-Fi antennae. Don't think that would have anything to do with the 4G/LTE radios or regular antennas. Overall, it was working, so I don't see how it could just magically stop.

If he bought the phone on a lease from T-MOBILE and never fully paid it off T-Mobile would black list it. Or if he sold you a lost\stolen phone.
You can contact T-Mobile or check the IMEI on one of those checker sights to see if it has been blacklisted.

You can check to see if you're blacklisted by visiting the T-Mobile website and using their IMEI checker. If you're blacklisted you would not be able to place calls. I will attach sample AT&T APN that works for me. I'm on Cricket and not StraightTalk but it may work for you.
For all who helped out on this post, THANK YOU! I figured what my issue was. SIM card is fine and the data settings work as long I don't configure the MCC & MNC settings. Changing the MNC from 260 to 410 is what caused my saved APN to disappear. Not sure why that happens, but if any of you have an idea of why, direct me to the thread that explains this or if you know, quote this reply. And another thing, I am able to send texts and make calls, but due to the location I was in, texts sent at half the speed of smell and making a call was impossible due the phone claiming I was "not on a registered network" even though ST is a network (duh). I have no service issues on my Note 3 N900A when I that. Anyone think it could be because AT&T's device antennas differ from that of a T-Mobile Note 4? Personally, I don't think they would since they are both GSM and operate on the same bands (I would think), even though the Note 4 has "newer" technology. Not really worried about data, texts or calls since I have Wi-Fi in said location.
Again, thanks to those that helped me out. And, again, if anyone has any ideas to the information said above, by all means give your say or direct me to where there is substantial info.

[Q] T-Mobile N6 on Verizon - LTE not working

Hey guys,
I bought a Nexus 6 two months ago while I was on T-Mobile. I got fed up with T-Mobile service (constantly dropping calls, not receiving all text messages, etc) and decided to switch to Verizon. I took my phone to Verizon last night, they scanned it and gave me a nano SIM. I was surprised how easy it was, given the headaches others have seemed to endure trying to get a Verizon SIM. Everything seemed to work on Verizon's end, according to the person who helped me.
The problem is, I can't get LTE to work with voice/text. If I go to Settings -> More -> Cellular Networks -> Preferred Network Type, I have 3 options to choose from: Global, LTE/CDMA, LTE/GSM/UMTS. If I select LTE/GSM/UMTS, I get LTE data, but I can't send/receive calls or texts. If I select Global or LTE/CDMA, I can send/receive calls and texts but I only get 3g data. If I go to Phone Info (*#*#4636#*#*) and set network type to LTE Only, the same thing happens...LTE data only, but no calls/texts.
This is about the limit of my ability to troubleshoot problems. What am I missing?
Thanks in advance for any help you can provide!
Did you properly configure the APN settings for Verizon? Your problem may be with that. Do a Google search for Verizon APN settings for Nexus 6...your answer may lie there.
most people have to factory reset their phones when going from another carrier to verizon, to get lte to work properly.

There were about 50 APNs when I checked. I deleted all of them and created a new one based on the following:
Name: Verizon
APN: vzwinternet
MMSC: mms.vtext.com/servlets/mms (with http, but won't let me post when typed out)
MMS port: 80
APN type: default,supl,mms
Everything else was left default. Restarted my phone. I am still only getting 3g on Global and LTE/CDMA, still can't make calls with LTE/GSM/UMTS.

I did a factory data reset this morning.
There are at least 5 - and as much as 10 - APN setting setups for Verizon. You may have to try them all. I put a Verizon Sim in my N6 and they all showed up in the list of APNs. When you deleted them you may have deleted the one most compatible with the N6. You may have to reset, put back in the Verizon Sim, and hope they all repopulate the APN section. If not, you'll have to search for them all and try each setup.
I can reset the default APNs and they will all show up again...without having to factory reset.
Do I need to reset the phone without the Verizon SIM inserted? I left the SIM inside when I reset this morning. I only ask because you mentioned resetting the phone and then re-inserting the Verizon SIM.
Thanks for your help.
I generally remove Sims and SD cards (not applicable here) when doing a reset as my line of precaution. Since you are able to restore the default APNs, do so, and try each one till you get the proper one.
Tmobile has their own software version/radio pushed out to Nexus 6's. You can try loading the Verizon software version/radio and see if it works.

I found the problem. When the Verizon rep installed the sim, she immediately dialed *228. After googling LTE problems, I've found out that *228 on a LTE phone is a very bad thing. I got a new SIM and everything is now working.
Thanks again!
