Changed my Settings -> Wireless & Networks -> Mobile Networks -> Network Mode to "WCDMA only"
Now I don't get stuck switching to the useless 2g, and my 4G restablished pretty quick if the connection is lost.
I just discovered that I can get 3MB download on 4g at my house, but the upload speed is under 100kbps. which explains the 4g flappping... I have no idea why such a difference....
Anyway, hopefully this will help when wifi goes to sleep and the 2g/4g switches hangs for minutes at a time.
YMVV...
also did a shark tcpdump and discovered that one of the apps is talking to a amazonaws ec2-204-236-220-254.compute-1.amazonaws.com for some reason...
The 4g icon seems to show for both utms and hspa+. Judging by your speeds it seems you are only getting utms(3g) which may explain your slow upload speeds.
To vibrant owners that's everyday use.

Is it normal for the phone to go straight from "4G" to "2G"? Should the phone ever show "3G" or anything of the like? I was in an area on the coverage map that said "3G" but the phone was hunting between "4G" and "2G" where "2G" will absolutely access NO DATA... Is it also normal for "2G" to be useless..
Dial *#*#4636#*#*
Then "phone settings"
Then change "wcdma preferred" to "wcdma only"

Just did that, seemed to show 0-1 bars of 4G and it was still enough to get data to load, so I guess that works.
Is there just no 3G that will ever display on this phone? I know there is a mix of HSDPA and HSPA+ in my area, but it's only ever said 4G.

Wait what? Doing that is going to make it so that you will only ever be able to use data if you are in a 4G/3G data area.
T-Mobile does not have a very big 3G coverage map, so doing this essentially makes it so that you have to stay within a known 3G area. 2G, IE EDGE will get you around 150kBps on T-Mobile which isn't really all that bad all things considered.
I would definately switch back to the Auto setting.
The problem is, even with 4 bars of 2g, the phone literally cannot browse the internet at all... almost as if I were connected to GPRS.

Yes. 4G (HSPA) doesn't really require better signal strength than 3G (UMTS) - so an area is either 3G or 4G capable depending on if T-Mobile has upgraded the tower or not.
2G (EDGE) can work on a much weaker signal so your phone will drop back to it from 4G.
Please correct me if I'm wrong
this is what i put in a similar thread:
I'm guessing the reason you won't see 3G is because Tmobile has upgraded most of their 3G network to HSPA+ so it'll show the 4G unless you actually go to a place that still has just 3G versus the HSPA+
I'm currently running eagles blood 2.3.5 custom rom and my data is wacky. Mostly my data will say 1x which is cdma technology, which I usually get decent speeds with. But now I get H appearing which is HSPA. Is there anyway to keep just the hspa. Apps like Netflix don't work on CDMA and its very annoying. So what's the deal? Is my data wacky or do I need to change my preferred network? It's currently set to WCDMA preferred.

I think you mean GSM, not CDMA.
Go to your Settings, Wireless Networks, Mobile Networks, Network Mode, and change it from GSM/WCDMA to WCDMA only. Now if you are anywhere where there is a 3G/4G signal, you will get it instead of the phone switching to a higher 2G signal automatically. However if you are in a 2G area, you will need to switch back to GSM/WCDMA.
no hes right its cdma technology, i think it might be simple, if u go into ur access point simple is probably checked off u need it to be tmobile and hit search networks even if it says error keep doing it until u get the option to choose tmobile , same thing was happening to me on fauxs rom lol i think verizon uses that too it looks like this rite....1X
Iwent into the access point settings and its checked off with T-Mobile. No dice, still switching back and forth. I also live in an aera that has hspa+. Its weird because on my old mytouch slide it was able to just use the hspa network no problem. With this switching its severely draining my battery. People said they can get 24hrs with there phone on this rom, I got 6 today. Thanks for the replies guys, I really appreciate it.
UPDATE: Wi-fi calling works fine which is confusing that I'm still getting 1x when my network settings are all set to t-mobile

So i downloaded Elixir and heres the deal:
Eaglesblood:
1X uses CDMA
E uses GSM
H uses HSPA
Stock:
2g uses GSM
4g uses HSDPA
is there anyway to fix the eaglesblood rom so it uses just the 2 like stock does?
Is there an order to the way Skyrocket works:
If LTE is available it would connect to LTE
If LTE is not available it would try to find 4G and connect to it
If 4G is not available it would search for 3G and connect to it
If 3G is not available, it would connect to "normal GSM"
Skyrocket is a LTE/4G phone, so does it mean that whenever I make phone calls I should be connected to LTE or 4G?
I had 4G showing in the top bar for 3 days but I haven't seen 4G all day today.
And I do not see LTE or 3G there either (I am not sure if there is LTE in New York).
There is just WiFi and those signal strength bars.
If it says 4g and LTE under your are in a LTE area. If it says 4g you are in a hspa+ area. If it says E you are on edge.

Oh and when you make a call it will say 4g you can't make calls with lte only 4g.

The indicators in the info bar can be misleading. If you want to know which network you are connected to, go to "settings", "about phone", "status", and look under "mobile network type".
And for people that have data connection issues from time to time, I am willing to bet that if you look under "mobile network type" while you are having the data connection problems you will see the network type changing every few seconds or so. The phone is generally in an area where there are weak data connections in all areas and it can't decide which network to grab hold of, therefore, none of them work. I think this isn't a problem with the phone, but a problem with how AT&T's towers handle connections in weak areas.

That's because you're connected to wifi. When using wifi, the network icon goes away. If you turn wifi off, you will see it again.

Scott1479,
So I still don't see 4G. However under "Mobile Network Type" it alternates between HSPA and UMTS - I understand these are 3G networks. Very interesting
There isn't voice over LTE on AT&T (or anywhere else as far as I know).
ITS at work told me today that Telstra are switching off the 2100 network tomorrow (31 Aug) and that my phone might not get data connection afterwards - has anyone else heard about this and know if it is true or not?
I find all the frequencies plus 2g, 3g hsdpa, edge nextg stuff confusing...
I've not heard this before. I, too, am fairly ignorant when it comes to mobile networks.
90% plus of my data usage is over Wi-Fi, but I'd be very miffed if I had no data connection at work done I rely on my Exchange account staying synched.
Of course, all we have to do is wait and see what happens tomorrow.

Yep, cross fingers and let's see. Reading a bit about it on whirlpool and it may be that we drop from HSDPA on 21,000 to the slower Edge on 850, hope not!
EDIT - the little signal indicator in the notification bar has changed from 'H' to 'E' for me over lunchtime... wonder if thats it. Browsing does seem a fair bit slower
E stands for Edge (2 /2.5 G) ...
Whereas., H stands for HSPDA (3/3.5G).
Try selecting WDCMA only in your Settings > Mobile Network Settings >Mobile Network mode.
This should give you only a 3G signal., if available. . Or else no network at all!
You can try switching back to GSM /WDCMA auto and be able to see the network back again.. In this mode it will select the best available option.

Thanks for the tip. If I set my phone to WCDMA Only, I get no connection., So I've left out I WCDMA Preferred.
By the way, I don't have those setting options, but I can get there by entering *#*#4636#*#* in the phone disaster and selecting Phone Information.

Weird, I use the same shortcut to get to that menu and tried wcdma only, my data signal indicator is now 3g (sometimes H).
No idea what frequency it is using but I'm getting data and presumably it must be better than E, edge. I'm in metro Melbourne btw

On CM10 (and I know you are running that ) you have a toggle called 2g/3g and in the settings you can change the network modes.
I have set them to 2g/3g only, because normally I'm in a WI-FI area and there 3g is useless.

Edit the screenshot wasn't working
I guess, the 2G/3G toggle option is the same as GSM only or WCDMA only option.
Edit : Ok, the pic in the above post just loaded... It's the same way of doing things, a bit differently though !

Of course, H is a lot better than E...
In fact, H is (just) better than 3G as well.
And as far as you are getting H/3G, leave the frequency to the network Radio Engineers to handle

Hello, this sounds interesting to me. In fact, I do not have an active 3G data plan or 4G and I am currently using 2G. However, when I set the airplane mode off and the phone starts to pick up 2G signal from cell towers, it also pick up the 3G signal too. In fact, I can see on the signal strength bar a 3G or H+ icon that are constantly changing with some up and down arrow signs that indicate that my phone might be downloading and uploading data. Can anyone explains this phenomenon? For sure, I can not access to the Internet without Wifi.

go to settings-mobile networks and there will be option for mode
if the mode selected if gsm/wcdma - then ur phone will pick up 3g signal if it's available in the area irrespective of ur plan..this means ur carrier has activated 3g services..u can deactivate by selecting mode: gsm only!(2g mode)
wcdma mode is 3g only!
hope this is helped!
If you truly can't have 3g on your plan, phones will communicate with towers due to the requirements to have a phone be able to call 911 even if it is not activated at all.

Maybe it's just scanning the available networks or something? Do you have data connection disabled at your device?
What is this thing about a 3G data plan?
A data plan is a data plan. Your speed depends on your phone hardware and what your provider had installed in your area...
At least that's how it works here in Norway, they can and do limit our download speeds after a certain amount of data is transferred as I assume they do elsewhere, but even when I pass that threshold my phone reports using 3G...

the situation is not same everywhere...
like in India and more countries, 2g and 3g services have different rates and are users can opt whether they want a 3g plan or 2g plan....although speed is more in 3g!
