...and nobody at AT&T can tell me why. In fact, when I showed them the phone with the H and 3 bars at the Device Service Center, they claimed they'd never seen such a thing.
The backstory is this: I've had good service at my home for a dozen years. I've always gotten solid E reception. About a month ago, 3G reception started to creep into the picture, although at a very low signal strength. It bounced between E and 3G every few moments and I started getting lots of dropped calls, no dialing, missed calls, etc. where that never happened before. I did some research here at xda and decided to drop Airplane Mode from my settings and add a 3G on-off switch using Advanced Config. After some futzing around, that worked pretty good but now whenever I try to switch to 3G, I get HSDPA. Go figure? Not that I'm complaining, because it's pretty darn fast.
But what the heck...only one Device Service Center in a city this size (San Antonio) and they've never seen a phone showing HSDPA? None of this really means anything, I'm just looking for explanations/comments.

Then why do my bars read H, not 3G? Actually, based on some online research, HSDPA appears to be a superset of 3G...a.k.a. 3.5G. At any rate, the "tech wizards" at the DSC had never heard of it.
I've got a Touch Pro running on T-Mobile network. Their 3G seems to be a different
frequency than the TP can receive. If I turned on HSDPA and then wander into an AT&T 3G zone and my TP picks up their 3G network, will it overpower my T-Mobile Edge and put me into roaming?
The H is the same as 3G like the other guy had said. Plus if you went into Advance Config. to change the setting then that will replace the 3g with the H. Which is not a big deal. All the phones in Europe use the H symbol in the US we get that damn 3G. Personally I like the H ova the 3G. H=High speed
So really and truly you have nothing to worry about. Should be happy you have the H showing up than the 3G to me H is a lil faster on some phones!!!!!!
att hides their hspa icon under the 3g icon. so you never know the difference between hspa 3.5g or umts 3g. if you flashed a new rom, updated your phone canvas, changed some icons, enabled it, or who knows, chances are you are back to the standard way the rest of the world has it, with the h icon.

I have had a Hermes / Vario 2 on Tmobile for a few years, and moved to a touch pro in the last month.
Prevously I used to see a G symbol and a 3G symbol about 60% and 40% of the time respectively. I had spoken to TM and my account was HSDPA enabled even back then.
Now I see a G or an H about 80%/20%. I am on W&W and have been assured that HSDPA is enabled. I never see 3G.
Incidentally, i get about 30 kbits/s on G and 380 on H.
Has 3G been completely superseeded by H even though the coverage seems not to be as good?
Yes. Simple answer.
HSDPA cooks 3G.
Clue:
Wikipidia: HSDPA or UMTS
T-Mobile UK's 3G network is now 100% HSDPA. so yeah, you shouldn't see the 3G symbol unless you are on a call, and every other time, it should be the H.

With the raph if you have HSUPA (upstream) enabled then the network will always be in HSPA mode. It should switch back and forth between 3G and H only if you are only using HSDPA (downstream) since the raph would behave just as the hermes would when using the data connection.
Not entirely sure on that, cos i don't have HSUPA enabled and i only ever see the 3G icon when i am downloading and on a call, so that both can continue.
My Athena worked in exactly the same way. H all the time while in 3G coverage, but dropped down to 3G when downloading and on a call so that both could continue.
Of course, I'm no network engineer so i could be wrong with the technical bits, but this is certainly how i have experienced T-Mobile wherever i have been down here on the south coast.
And t-mobile certainly did say a while ago that they were updating their entire 3G network to HSDPA back in late 2006/early 2007!!
My office has an 850 abnd ATT mini cell installed in our server room. The tower was installed because we were getting bad blackberry coverage which are all Edge models. I happen to sit directly outside of the server room and am about 15 feet from the mini cell tower. My Fuze is insistent on using the 850 2G connection instead of getting a 3G signal. I am in downtown Chicago which has fairly decent 3G coverage. I am on the 50th floor of the ATT building but I can't get ATT 3G service! I can go down to lower floors and I have no problem getting 3G. I can only assume my phone is being told "hey, I have a killer 2G signal, lets use that!"
I am able to disable 3G by using com manager. Does something similar exist for disabling 2G? Is there something I can do when I am at work to not use the 850 band? Unfortunately, moving is not an option.
You can enable the 'band select' part of the phone options, and lock it to WCDMA
As I recall, the registry entry to do so is:
Code:
[HKEY_LOCAL_MACHINE\SOFTWARE\OEM\PhoneSetting]
"ShowUMTSBandPage"=dword:00000001
Att uses cdma?
I do believe Da_G just had a bad mental picture of the screen he's talking about.. The page in question is not page you'd tend to visit frequently
Top drop down: Auto, GSM, WCDMA
Bottom drop down: Band selection
I don't The exact options for whats in "Band selection" but it lets you force the phone to use only certain frequencies... The only problem I see is, I do believe AT&T uses the same frequencies for 2g and 3g... or at least depending on what area you're in, 3G might be on 850, or it might be on 1900.. so you travel a bit and your 'force 3g' doesn't work anymore... i'm too tired right now to figure out if your phone would still work in such a situation... I think so >.>
I already had the band select reg key applied. I changed the phone options from auto to WCDMA.
I am seeing an H instead of E but I am not seeing HSPDA speeds. It "feels" like I am on a 2G connection. One speed tst did show 483kbut/sec but I am use to seeing 1200-1500 when I have true 3G.
I know ATT uses different bands in Chicago for 2G and 3G. If they start using 850 for 3G like BG reported then my problem will dgo away.
I just want to stream Cubs games from my MEdiaCenter while im at work... is that so much to ask? Need at least 768 to get a decent picture.
Sounds like you need to enable the Advanced Network tool, and turn on HSUPA

Your typical "GSM" carrier uses Wideband CDMA (W-CDMA) technology for 3G.
The correct answer is NO att does not use cdma. lol
What kind of answer was that anyway? "typical?" hahahha
(ok work time! this 5e isnt gonna install itself
hi
just used bandswitch and change to UMTS then do a solf reset
and u will have 3g. it work for me.
this is the link i have for u.
sry my english is no to good but i try
u need to run without the touch flow
so u can see the program

I got a Jiayu G3 knowing it would be a gamble concerning whether or not it supported 3G on the AT&T network, which operates 3G on 850mhz and 1900mhz.
Naturally, I lost the gamble and was stuck with EDGE, or so I thought. I was driving around today, just 1-2 miles away from my home when I looked down at my phone and noticed the H over my cell signal. I ran a speed test and sure enough it confirmed HSPA due to the 4mb down and 1mb up speed. I even go to network provider search menu and it shows both AT&T 2G and 3G selections. Then as I went back home I noticed it was back to EDGE again. Now I have an old Samsung dumb phone that shows what band you are on in a developer menu, and I confirmed both 850mhz and 1900mhz bands have decent signals in my house, yet my Jiayu can't connect to it.
Can anyone help, this has really confused me.....

I think you missed the part that I actually get 3G in some areas, and it's definitely not on 2100MHz. It's 850 or 1900MHz.
Is there a way to see and change the LTE BAND that my phone is on? Rogers support aws, 2600, 700. So I was wondering if I could manually change between them. The S5 has that option in the hidden menu, so I'm hoping I could do the same on this one.
Thanks.
The phone choose the band himself, if he don't find bands authorized by your phone company, he can't use them.

*#*#46363#*#* > Phone information > Set Preferred Network Type > 'LTE/GSM auto (PRL)'
That's as far as you can get in telling it what network to operate on. It won't let you select specific bands (at least not stock). Mine was set to 'TD-SCDMA, GSM and LTE' out of the box (international version) and since I don't plan to use my phone in China anytime soon, it didn't make sense for the phone to waste resources searching for a TD-SCDMA (China's homebrew 4G) signal. Haven't noticed much improvement to my LTE signal though, still the weakest radio I've seen in a 'flagship' in a while.
Thanks.
I am also on Rogers.
Does that mean when I am on the phone, it will revert to EDGE instead of 3g by using the LTE-edge setting?
I have major issues with reception on this phone.
LTE Works Fine but the 3G/H+ signal is awful, absolute disaster on this phone. It is extremely, extremely weak. And I lose coverage often and over 50% of the times my calls go straight to voicemail because Rogers uses 2g/3g for calling. The phone can't drop back to 2G or 3G in time to receive calls when on LTE
Rly frustrating. Have tried playing with all the settings.
Same issue

I'm having issues with 3G H+ too. Dont know its CM issue or not coz I had nice H+ signals on Color OS...
Can't even use internet data. most of the time network drops after using internet for a bit.. Network just suddenly gone and after that it comes back with no internet. Internet comes back online after a while...
Really worried.. and annoyed coz can't seem to find any solve for this. Even Mahdi rom had this issue..
Yesterday I received an email from my carrier (Pure Talk USA, using ATT towers) telling me that it's time to buy a new phone. They're (presumably ATT) sunsetting 2G service, rendering my phone unusable. I know the "4G" in the name is probably meaningless, but is the Relay really that old? Has anyone else received notifications like this?
We've never had data service in the US. We were in England a few weeks ago, on a travel SIM which did have data. I found it almost unusably slow, and saw "G" and "E" by the signal bars.
Is it really time?
EDIT - After a little searching, I find that the Relay does both GSM (2G) and UTMS (3G). I had a setting limiting it to GSM, which is the right thing to do to save power, though once I had data in London I should have opened it up to either, in order to get decent speeds. I have only ever used it with GSM in the US, which might be why they think it needs to be replaced. This afternoon I switched to the "either" setting, and I'll need to write to my carrier about this. They sell data also, so I may want to pick that up for a month, and see how well it works with UTMS enabled. It was certainly close to worthless with just GSM.
I've also seen some reference to the phone doing HSPA+, with is either 4G or partial 4G, or at least better than 3G, but that doesn't show on the Cyanogenmod page.
https://wiki.cyanogenmod.org/w/Apexqtmo_Info
https://en.wikipedia.org/wiki/AT&T_Mobility#Radio_frequency_summary
The relay is a 3g phone, but it also supports 2g networks as a fallback. Pure Talk probably just broadcasted that message across the 2g network, and any phone that could receive it, did.
I got an email back from their support, and it's basically as you say. Some time later I plan to disable GSM and make sure I can still talk over 3G.
More information here...
As mentioned previously I had limited the phone to GSM - 2G. The menus in the phone were a bit confusing, because it gave the option of GSM-only, WCDMA-only, GSM/WCDMA-auto, or GSM/WCDMA-preferred. When I first bought SIMs and service for the phone, I looked at WCDMA and said, "That's a Verizon thing, irrelevant for my GSM phone," and set it to GSM-only. In reality that labeling is misleading, because it's not WCDMA, it's UTMS/HSPA - 2G or 3G+. When the phone calls itself "4G" it's not LTE, it's HSPA+, which is better than 3G, but not as good as LTE. So it's a bit disingenuous. However I did test it, and though I don't have data service, when I turn data on, even with no registered APN, it tells me I have HSPA+ service available. ("H+" on the status bar)
I just wish I'd known this before going to England, where I had a travel SIM with data service, tried it, and thought it unusably slow. I was getting "G" or "E" on the status bar, which I have now learned is essentially dialup or a bit faster.
