Same location, issue when on 4G, but none on LTE? - T-Mobile Samsung Galaxy Note 3

When my T-Mobile Note 3 is connected to LTE, I have very stable connection, regardless of the speed.
But when it switched to 4G, there is zero our unstable connection, even when I have full bars.
I have the default APN. Anything i need to change? Tested throughout Nevada and California.

Monitoring this closely, the connection is lost or unstable as soon as it switched to 4G from LTE OR when there's is no connection.
Example:
1. On LTE, good internet connection, full bar
2. Auto switch to 4G. Still full bar. No internet or unstable
Example:
1. Coming out from subway, had zero bar before
2. Connected to 4G, no data
3. Connected to LTE. Have data

switch 2G/3G manually?

Hi..
Anybody knows how to switch manually to use 2G or 3G only?
Because sometimes when I am on the 3G coverage area, the phone still use the EDGE data connection rather than the 3G/HSDPA data connection. It really annoy me because the speed is slow if I use the EDGE connection.
In my old nokia, it allows me to use the 2G/3G connection only, so I wonder if desire can also do that.
Settings/wireless & networks/mobile networks/network mode. The auto is however set up quite well. The reason you keep finding edge, is that the edge signal might be stronger that the 3G. 3G will always be the preferred option for the phone, but keep in mind that a strong signal on edge will beat a poor signal on 3G where download speed is concerned. Therefor your phone tends to pick the fastest/strongest signal in your area.

Distinguishing between 3G and 2G connectivity

I am using a flashed Epic 4G on the Page Plus network. Whenever I have a data connection, the 3G icon appears on my phone. Does this 3G icon refer to true 3G (i.e. EVDO), or does it include 2G speeds (i.e. 1xRTT) as well?
Are there any indicators out there that can distinguish between 2G and 3G data connectivity?
On the stock framework for Epic they use the 3G icon for 1x and 3G connections. Many custom ROMs/themes have a proper 1x icon in them. Also, you can download Network Info II from the market and it'll show what mode you are in under "Net Type:" about halfway down the screen.

[Q] Data network issue

Hi there;
I have recently owned a t989 Galaxy s2. Everything is OK except one thing that is data network. In my country(Turkey), there is no 4g network infrastructure yet so 3g is used currently. When I get the edge signal(it is on the status bar) it works as intended but when it turns to 4g signal (4g sign on the status bar), I am having trouble trying to connect to web. In the specs, it says it supports e/3g/4g but I have never encountered a 3g signal(3g sign on the status bar).
Is it obviously a radio related issue or something bad lying behind the ROM?
Note : Curently sitting near the PC and it is 4g that I see on the status bar and I am unable to establish a connection :S
Currently used Rom/Radio : Bullet v6 Android 4.0.4 / default radio comes with it(tried others as well)
Thanks in advance
Our phone does not have true 4g capabilities. it does have 3.5g. So if you say your area has 3g... then technically it should be able to use "4g".
I have yet to encounter the 3g signal symbol on my phone so i can't help you there... didn't even know we had that symbol lol.
Having "4g" symbol does not necessarily means you have fast data speed. It really depends on your area. My phone would say 4g but in reality.. it has no data or very slow data transfer speed. so don't trust that symbol. You should also check if your AREA supports the 3g network yet.

[Q] Note 2 not auto switching to 4G?

Hi guys, I'm plenty familiar with the Note II having had mine since October release. I'm having an issue where I will be in a solid 4G coverage area (at my home) and my phone will stay in 2G mode.
There is a problem with either the tower or the phone, I'm leaning toward tower because my wife has my old Sensation 4G which is also staying on 2G. Have any of you encountered/noticed that your phone stays in 2G even though you are in a 4G coverage area? For me either on the Sensation or Note II, I just pick WCDMA, 4G pops in and works great. The only problem is that I have to remember to put it back on auto when I leave the area. I looked up and attempted the cell codes for making the phone prefer 4G, but without success there. Also my phone picks up 4G automatically when I'm at work, so again leaning toward tower (but how and why the tower can control this I have no idea).
I also noticed some threads claiming wifi calling would detect wireless networks nearby and disable 4G. I'm leaning towards BS on that because 1. my wi-fi is almost always turned off (true unlimited 4G plan), and 2. when I disable wifi calling all together it still exhibits the same behavior.
I'm running out of ideas - any help is appreciated!

In settings>more settings>mobile networks>network mode:
You should ALWAYS be set to GSM/WCDMA (Auto mode)
This will automatically get you the best data signal available at your location. If you only get 2G in some locations, that's normal. You can try calling TMO support and have them check your address to see if you SHOULD have 4G at that location. If you really want to try to see what is going on, install an app called Open Signal Maps form the Play store. Among other useful things, it will geolocate the towers you are connected to complete with distance and mapped street address.
Where I live I only ever get 2 or 3 bars of 2G data. I use the TMO wifi calling app for all my calls and texting. This is only way I can get reliable service at home.

Thanks for replying vouty. When I switch from auto mode to WCDMA I have 4 full bars. That's the funny part. Speedtest is giving me around 12Mbps down 3 up on average (I live right by the tower - like .5 mile), so there is for sure something strange happening. If I keep wifi on it really isn't an issue, but I prefer to not mess with wifi and just keep it in 4G while at home, but as frustrating as this problem is, the phone refuses to switch from 2G on it's own. Once I toggle from AUTO to WCDMA, and then back to auto - it will stay on 4G. It's almost as if I am waking it up and causing the phone to re-detect the signal.

Cool app, very useful, appears I am on 3g at home. Turning off wifi to see if it changes to edge while using data.

3g signal issue

So here is my grudge as of now with the gnex. When I go from roaming to 3g or airplane to 3g, it takes an unbelievably long time to actually GET the 3g signal. It will show me that I have 3 or 4 bars of service but does not show me the little 3g icon. I am currently running Sourcery 3.2 as my rom and have my mobile network set to CDMA only. Is this a common issue or do I have a possible shotty gnex?
