Signal/band change - AT&T Galaxy Note 3 Q&A, Help & Troubleshooting

So I'm at work for 12 hours tonight sitting here thinking something must be able to be done about my poor signal at work. Once again I dive into the service menu and start going through the network types one by one checking signal strength, asu, and tower info. When I switched to lte/cdma I get full signal lte. I'm pretty sure this is coming off of a Verizon tower about 1/4 mile from me which is awesome however I'm wondering if any of you have done this on previous phones with AT&T? have you been hit with roaming charges? Any negative effects? Comments in general?
Notice in the picture the tower info is different, my imei has changed, my phone number is gone. However it says that I am not roaming and gsm is in service.
All phone features calls, internet, and text work without a hiccup.

Moble Data Disconnects

Recently I've notice my mobile data will disconnect sporadically. I'm not sure if it related to the phone or service. Is there a way to tell?
BTW, I'm in the Los Angeles area.
I've been having this problem too. I haven't been able to find a fix yet.
Have you tried updating PRL and Profile?

I had the same problem when sprint was doing NV deployment in my area!
My problem went away after sprint was done in my area!

Do you have sleep mode on or data connection checked in your power saver menu?

I've noticed the same here in VA. It'll drop for a few seconds then come back.
I still have a connection, but I am noticing 3G/4G flickers in northern Virginia. Hopefully our markets go live soon (officially, anywhoo).
I've updated the prl and profile and have had sprint reprovision data twice. I'm not using battery saver or anything either. The only thing that seems to keep data stable is if I set mobile data to 'CDMA only'.
LTE phone in a non LTE area has caused me grief. Could this be the problem for you also?
I've been having the same issue. However it didn't start till after I unlocked my bootloader and flashed a new ROM. I think it may just be bad timing but I've called Sprint to see if they are doing any work and I've been told no. (For what that's worth)
I also have a GS 3 & 4 and neither of them are having the issue.

I'm thinking that is the cause of this issue. About 60% of San Francisco has LTE now and I'm thinking the phone just has trouble staying to one tower or another. Still it's a frustrating issue.I didn't have any of these problems on my iphone 5 before or after switching back and forth.

4g issues on Optus network

This is an ongoing gripe of mine. I'm wondering if it's just me or if other people have this problem. When I'm on 4g it intermittently turns off data for a few seconds. The 4g icon goes away and comes back a few seconds later interrupting my connection. Only happens on 4g. If I set the mobile network to just 2g or 3g I don't have this problem. I've tried lots of different modems. So I'm wondering if it's an Optus thing or an issue with my phone? ?

probably poor coverage of 4G network
Why 4G when 3G is enough for watching video etc etc?
And it drain more battery also

I'm literally right next to a big city. Its not a coverage thing. If I have a 4g phone why not use it. I get about 24 hours of battery life from it so that's not an issue

Significantly reduced signal strenght 4.3 or Sprint's bad timing?

I updated to 4.3 just now and my lte signal dropped to 1 to 2 bars, from a constant full bars. I noticed the performance is equal, meaning it may be just a difference in the sensitivity of the antenna's display of good signal however, it drops from lte a lot and stays in 3g. Has anyone verified the changes in the new modem? Any other bugs I should be aware on the 4.3 update? Also, Dashclock widget doesn't work on htc's widget lock screen.
Looks like before the bars were for voice and now they represent data. That's the way it is in AOSP.

I imagined since there were no changes in performance per se. I just wish I could restrict my one to lte only. Either 4g or no data.

I work relatively close to a 4G LTE tower before updated it showed full 4G with fast speeds, now it shows little to no 4G and would switch to 3G. I tried to Factory Data Reset with PRL and Profile Update and still shows the same, and I'm running all stock no root, and I'm pretty sure it's not the tower.

This is correct. You can verify this by connecting to wifi and then disabling mobile data. Your bars will instantly change.
I like this change. Now I can see that it is not possible to have more than 1 bar of 4G pretty much anywhere in my area. No wonder the speeds are so average and I almost never get 4G, the Sprint towers are all so far off the main roads that by the time the signal gets there it's weak. You can get full bars... if you drive up to the Sprint call center in Bristol, TN.
Before this change it was a lot harder to tell whether you were getting good 4G or 3G reception.
Edit: I just want to say that the reception itself is largely unchanged. When the phone goes from 4G to 3G, nothing will make it go back to 4G except toggling the data off and on.
Just to throw this in the mix. I live in an area that never had 4g but after this update I have it now. My signal strength also shows the one bar but coming from 3g only my connection now is 4g and has increased significantly. Maybe this new radio has a factor that extends the overall 4g coverage? I guess it could be just timing and 4g was opened up in my area but like I said I now have it after this update.

Poor signal reception on AT&T with AT&T Note 3

Switched to Note 3 from Lumia 920 (phone upgrade, had my SIM replaced as well). Now on all places where I previously had stable LTE signal my Note has couple bars of HSPA or from time to time HSPA+. I still can catch LTE signal from time to time but not in the area I live (and had stable LTE for a year on Lumia).
What may be the reason? Is it a phone problem or just Nokia modem has better sensitivity?
Don't want to initiate replacement procedure, the phone seems perfect in all other aspects...
I've also been disappointed with the reception vs the S4. I'm also having trouble installing apps from the play store >.< even on wifi.
I have bad reception also
I am thinking of returning, I have had to switch to airplane mode twice in the past hour to get it to reconnect to LTE. It sometimes drops out all together when accessing the play store. I am in Baton Rouge, and didn't have any issues on my iphone 5.

That's crazy, I'm in Baton Rouge too.Just got my Note 3 from the Best Buy Mobile on Bluebonnet. Maybe its borked because of the impending hurricane doom.
Yes, switching airplane mode on and off helps to establish LTE link everywhere... But it switches back to HSPA in 20-30 min and never return back by itself. Definitely software bug
I'm getting much better signal than I ever got with my 920 or S3. I'm in Houston FWIW.

I'm from just south of Baton Rouge, reception has either been great or next to none for me. I can manually put the note 3 on lte but the speed at that point is slower than the 4g. Sadly my s4 active was nearly the same way...

Yeah, maybe the storm is causing issues ,I'm going to give it a few days.
In the same room, my wife's iphone has 4 bars and this one has 2

I'm east of Baton Rouge, in Hammond, and I've seen the same thing! lose LTE and sticks to HSPDA! Airplane mod does fix it as well. I hope it's the storm, but I don't thinks so!
For you guys with a Google play issue...
If you connect to a VPN like privateinternetaccess.com (also avaliable on the play store) and select a country other than the US it will more than likely work.

I'm in the Sugar Land/Missouri City area. That's strange because my house is a dead zone. I'd get 1 bar on my S3 and 920. I get 2-3 with my Note.

I live in SF Bay area and this definitely not storm, it's some software/modem firmware fault. It seems not trying to switch to LTE once kicked to HSPA. If I do airplane mode switch on a place I have good LTE signal it would jump to LTE and keep connected for a long time until I move and it loses it. After that it jumps down to HSPA and not trying to return back on LTE even if I go back to same place where it had full bars of LTE before
Well good to know it isn't just Southeast Louisiana. Also, just plain nuts to me that we're all posting in the same thread miles apart, go figure.
I haven't had time to switch my Sim back to my S4 to do some testing. But I feel like my speeds are definitely suffering.
Post your speed tests for comparison. BTW one of my favorite features about the s pen are the easy screen captures and edits.
Maybe it's just an APN issue? Has anyone tried playing with that? I tried a few from rootzwiki but don't really know what I'm doing in the APN neighborhood.

For what it's worth, FL is having issues as well. Play store has been wonky and the reception has been less than stellar. With all these reports I'm willing to bet it's something on their end.
I am going to try and swap it out at the local store tomorrow even though I ordered it online. I should be able to according to the terms. I am willing to give it another shot, although at work today I had absolutely zero signal just a circle with a line through it. I normally get at least phone and text functionality at work.
All your phones are perfectly fine - they just need a firmware update or two.
I've seen mine even drop off to edge just sitting here at my desk.

Swift kick in the throttle

So just got my note 3 Tuesday and am now experiencing blazing fast 0.45 mbps avg speed tests. I've tried searching for solutions, including the *# combinations that some people have luck with in the dialer, and none work for me to try and switch the signal. I don't mind settling for hspa only if need be as it's not long until the cycle restarts, but some repeatable solution would be fantastic. It is not rooted, but I do not object if there is no other solution at all. Any ideas, input, or suggestions would be greatly appreciated. Thanks in advance

I can't edit, but forgot to mention that it is dropping LTE signal everywhere I was fine on a note 1 and 2, and sitting right next to a gs4 with a good LTE signal, it would continually be on "4g". A restart or airplane mode on and off quickly will get it back on LTE but only temporarily. Is this typical behavior of a throttled phone, or could I potentially have a defective piece of junk?

The note 3 seems to not like lte in my area either, I don't think it's a hardware issue since it traded my first one back in and the new one does the same thing

Mine was doing the same thing. I did a hard reset (or 2] and it's running great. Locks onto LE and I'm getting 30mbps +. You will lose all your data though. ?

Make sure all your APN settings are correct and that your network mode is on LTE/WCDMA/GSM.
Thanks for the replies. I don't mind resetting the phone, just want to make sure it isn't a physical defect that needs me to return the phone. The lte here is normally very solid, I had no trouble on note 1 or 2 really.
How do I check the APN settings and see the lte/wcdma/gsm menu. When I searched I only found dialer codes that didn't work no matter how or how many times I tried them. None seemed to be specific to note 3. Google searches as well as using the xda app don't return anything, but maybe I am not searching correctly?

Never saw any notifications here, thanks for all the replies.
I tried the gsm lte settings and it never worked no matter how I tried. Restarts combined with changing the settings with that #* method and no such luck. Will I have to root to find a solution?
I never had been throttled before last month. Now I just got it again as I tipped 5gb.
I have 10 days left too on the billing cycle. That is gonna suck as it just got me again today.

I thought I was imagining things, but I think my N3 doesn't seem to lock on to LTE signals as good as my other phones.

That can't be a one off. This phone is on "4g" a number of times I see other phones on LTE. I'm not sure how next generations get worse as it is weaker than my note 2 was, but you are not alone for sure.
