I have noticed that when I am connected to the fast cellular internet the sign constantly switches between 3G to H. Like every 15 secondes.
It's not that the connection is dropping it's just it is always changes from 3G to H. I am on At&T and would like to know if it happenes to someone else.
As I read, At&T suppose to have an HSDPA and since I am in big cities like Chicago and Washington DC, if there is HSDPA it should exists in these cities.
So?? anyone using AT&T + KAISER knows what I am talking about?
should be worried?
i see this behavior all the time with my Kaiser, Trinity and Treo and never worry about it... most often the i'll see the "H" symbol when i'm tethering or downloading a file from a website or i'll see the "3G" or "E" if i'm in an area of town that doesn't have a strong signal... i don't worry about this behavior unless it affects what i'm doing, e.g., lose my internet sharing connection. just my 2 cents...

Thank u for your fast reply. I know sometimes the signal changes to E or even G if there is no high speed connection around but it seems that the H and 3G just changes every 15-20 seconds in areas with high speed connection. does it also happen to you? or anybody else?

I actually consider you lucky. At work in Menlo Park, Ca. I rarely get a 3G or an H... But I spent a couple of weeks going to SF every day and there I saw behavior very much like you describe. For me it seemed to want to switch from 3G to H as I was doing some sort of access like e-mail read or a download. Though that is probably just anecdotal as I didn't really make a study of it; just something I noted.
Cheers.
i have the 3g/H switch happening constantly as well. could this connection issue have anything to do with the sms issues (issue being sms works randomly), or totally unrelated?
Yep...this happens to me too.

I'm in the Chicago-North Suburb area and I see it change all the time too. I get a lot of HSDPA connections. From my understanding, this is a good thing!
Though I'm by no means an expert on HSDPA, 3G, UMTS or any of these, it's my understanding that HSDPA will give you data bursts of up to 5 times the connection speed of 3G/UMTS.

What it means on my 8525
Hi Guys,
Don't worry, you are not having signal quality or connection issues. On my 8525 (Hermes) the switch to H from 3G simply means the phone is using the data connection at the H (HSDPA) speeds. It shows 3G when data is not being transferred.
Yup. It's sort of like a combination power/hard drive light on a computer. When the "H" lights up, data is being read and written over the high speed network. The "3G" means the high speed network is available, your just not sending or recieving at the moment. At the slower EDGE speeds, the "E" is just a power light, showing the network is available, but no indication when you are sending a receiving data over it.
Someone correct me if I'm totally wrong, but here are my thoughts:
The H would be displayed when the device is accessing HSDPA or HSUPA. The D stands for download and the U stands for upload, right? But AT&T only has HSDPA right now, and not HSUPA. So when you're in an HSDPA area and browsing the web or sending and receiving emails, when the device is receiving information (downloading), it's on HSDPA and the "H" is displayed. But then when it needs to send information (uploading), since there is no HSUPA signal it switches to 3G and the "3G" is displayed. Hence the constant switching on the display as the device sends and receives data.
Someone please give me a gold star, or tell me I have no idea what I'm talking about!

If you see the H then you are using HSDPA, if you see the 3G icon then you are using UMTS. The difference is speed and the fact that if you see the H icon it means you can use voice and data at the same time.
I can stream live TV from my Media Center using WebGuide (free) and as long as I have the H icon I can talk on the phone at the same time I'm watching TV but if it switches to 3G I loose my data connection until I hang up the phone.
Mine mostly stays on H but swithces to 3G when the HSDPA signal is lost. HSDPA isn't avalible every where that 3G UTMS is.
Also HSDPA is 3.5G and UMTS is 3G. Meaning with UMTS you can get downloads of 384 kbps to 768 kbps and with HSDPA you can get from 768 kbps to 1mbps.
This is how it is supposed to work kids...
The H only shows up when you are using HSDPA. HSDPA would kill your battery in no time if it stayed connected all the time. your phone is smart enough to only use HSDPA when it is actually sending/receiving data. Think of it as a power saving feature.
I'm in cleveland and i just see an "H" all the time... FWIW...

But it only uses HSDPA when it's RECEIVING data, not SENDING. That's what HSUPA would be for (if AT&T had it yet). Right?
High Speed DOWNLINK Packet Access
High Speed UPLINK Packet Acess

That is correct. HSUPA should be coming soon according to Engadget: HSUPA

Perfect.!! Downlink = Downloading (HSDPA).. Upload data by 3G as AT&T is not supporting Uplink = Uploading (HSUPA)... smart one..
I'm not sure it is that simple...
I live in Jacksonville an i neverget an "H" except when i used shap's rom on my 8525; however, i get speeds from 600 to 980, so is this extremely fast UMTS, or is Cingular just inconsistant with their labels?

I also live in Jacksonville and found with the Tilt that I was only seeing the
3G icon and never the H icon until I installed KaiserTweak and set the HSPA option to enabled. Now I get the H icon but only during the data connection being active (e.g., sending a URL request and receiving the page load). The icon then turns to 3G when the Tilt sits "inactive."
Also just because you don't see the H for HSDPA doesn't mean its not working unless the REGISTY has the correct setting you will not get the H icon. the place is HKLM>Drivers>RIL>EnableHSDPAIcon = 1 (sometimes default is 0 which means you won't see the H icon)
Since my last posts on this topic, I now have my Tilt!
I am confused- why would AT&T not enable the "H" icon? If you are using HSDPA (and soon HSUPA), wouldn't they want you to know it?
Maybe they are afraid it will confuse people. They just want to market "3G" and people to understand it and see that icon, whether they are on UMTS or HSDPA/HSUPA?
Hi guys!
I was wondering why I dont get the "H" icon? I only have 3G..
At settings, HSDPA is turned on..
What could it be?

it also depends on your location if HSDPA is offered. not all areas/regions are HSDPA enabled.
Yes, First of all there should be HSDPA support in your area / supported by operator.
For instance, I see 3G icon in my Kaiser, While i am connecting, the H icon appears
And then again 3G icon comes back when the connection is established!
A week ago I got a second hand Tilt. It AT&T branded but a HTC rom was flashed to it, ROM version 3.28.405.0 WWE, Radio 1.65.17.56, Pototcol 25.83.40.02H.
My issue is I see not "3G" indicator on the screen in areas where I know there's coverage (my other phone does indicate 3G coverage). So what could this mean? Is something missing??
Any info is appreciated.
Thanks!

Having already read the HTC User Manual for the TyTN II perhaps? If you get the pdf from HTCs website (or even search for it) and have a read, you'll see that in areas of 3G coverage, sometimes the device will display a 'H' which is superior to ordinary old 3G.
My issue is that I'm in an area with 3G coverage, my other cell indicates this with a "3G" icon on it's screen, but my tilt does not indicate or detects 3G coverage. There's no "3G" or "H" on my display.

Can u post screenshot of your screen? What icons do u have there(on the upper bar)?
You may want to look for something like Kaiser Tweak or something else that disables 3g.. Also you can try tapping on the signal icon at the top and make sure that all the data/3g stuff is turned on at the bottom.
Don't know how to get screenshoot. On the top of the Today screen there's, from right to left, the task manager, the battery, the signal strength (just the little antenna and the bars) and the WiFi icon.
Where in Kaiser Tweak or Advanced Configuration Tool could disable 3G?
Kaiser Tweak = under Data
Advanced config = again, under Data.
Tried it...no joy!
Went to Adv. Config. and eneble everything under data connections. Still nothing.
Does your sim support 3G?

Did you check in Advance config to see if just the icons are turned of ? I believe you can just turn the icons off ( because some people find them annoying ) but still call and connect at 3G speed. Are you lacking speed or just the icons. ?
Let me re-state
I've had this Tilt for about a week, my other cell (Samsung A737) indicates "3G" all the time while I'm at work so yes my sim is 3G. This Tilt has never indicated "3G".
I went to Adv. Config under data connections and enabled everything.
What I'm trying to figure out, is this Tilt unable to detect "3G" or is it a missing icon thing.
IF
1. you have a 3g sim
2. Kaiser Tweak and Advanced config don't have 3g disabled
3. you don't have the "nodata.cab" installed
4. 3G data is turned on in the comm manager
5. HSDPA is turned on in /settings/connections/advanced network
6. All the proper info is set for your connection "media net"
and you still don't have 3g.
I would say at the very least do a hard reset or update your ROM.
Anything I'm missing?
Ok...more data...new questions
Where in Comm Manager can turn 3G on/off?
What does Medianet settings has to do with 3G?
Thanks for your answers ChumleyEX!

Hehe, when u have wifi enabled the 3G icon changes to the wifi icon, just try to turn of wifi and see if the 3g,H,E or G icon will appear.
That's a thought Mikulec! Tomorrow at work I will try this. I'm home now & reception here is crap!

Say what?
I'm sorry ChumleyEX but that's not an answer...I dont have a data plan so MediaNet is, in my opinion, not an issue. Like I said before, that didn't keep my other (and less sophisticated cell) from detecting 3G coverage... anyway more data!!
I tried turnning off wifi to see if wifi icon becomes "3G", that doesn't work, the wifi icon gets an "X" over it & does not become "3G".
Yesterday I found out that if you try to make a video call the cell tells you if there's a 3G network available, so I tried this in my office & it answers no 3G network available.
Last night I started experimenting with flashing, I knew this cell had been flashed before by someone else, for one this is an AT&T branded Tilt but the previous owner has using it on another carrier and when I access the bootloader among the information there was "Spl 1.0 Olipro".
I flashed a couple of Hard SPLs & a couple of radios to try and it got me thinking, could the lack of "3G" be a radio or ROM issue??

It definitely could be radio rom issue, but ... I am flashoholic, that means I flash almost every rom that comes out. And on most roms that I flashed the 3G icon changes after some time to the X, but after going to the internet via gprs the 3G appears once again. I dont know why is this happining, there was a disscusion about this, but I dont know in which thread.
The funny thing is although I have the X icon, I am in 3G area and I can make video calls and use the 3G cappabilities. So I dontknow why u can not.
" I knew this cell had been flashed before by someone else, for one this is an AT&T branded Tilt but the previous owner has using it on another carrier and when I access the bootloader among the information there was "Spl 1.0 Olipro"
So it's possible that the media net info is incorrect. Also, your simple phone that has the 3G show up is just that, a simple phone. This tilt isn't so simple.
if this link works, download the file and run it.

My carrier had some little problems during the past weeks, aparently they were working on something. I sometimes, for short periods, did not have data connection or no servic at all. Now the problems are gone and a speedtest today showed that at my home, the download speed went from an average 1 Mbit to over 5 Mbit!
However, the H symbol won't go away anymore! It used to switch to 3g when not data was transferred. I assume that this will influence battery life.
Is there anything I should be worried?
From what I recall, H is faster than 3g, as long as your in a good signal area, the H will always be visable, it will only drop down to 3g if the area your in has no H signal... and if there is no 3g it will drop to a 2g signal... simples, having the H does not meen that data is being transfered!
I am aware of the different speed levels, what I experience now is that the H symbol stays all the time, whereas it used to change to 3g when idling even in areas with very good reception...

Wait, I don't get what you're saying. Let me clear it up:
Very good reception = H
Not so good reception = 3G
You want to see H (means HSDPA which is a a type of 3G data, but it's faster).

Okay, I'll try that too!
I live in an area with very good reception and therefore the phone used to switch from 3g to H whenever data was transfered and back . Now, however, it stays on H all the time and does not switch back to 3g when no traffic occurs.
It is just a change in the pattern my phone behaves so I wanted to get some info on that...
Hi, it's your phone doing what it should by seeking the best signal.
H refers to HSDPA which is based on UMTS (3G). Consider it a 'turbo' version of 3G. It's sometimes also referred to as 3G+ because it's faster then 3G but not really 4G technology. The tower in your area most likely got upgraded to HSDPA that's why you don't see the 3G icon anymore.

Not correct, he mentioned that his phone was using H on demand before, so the capability was there already.
The problem is that H mode uses more battery than 3G, which is why it normally only switches to H during data transfers instead of continously being on.
Possibly your provider made a change which forces your phone to stay in H mode. On hardcores homepage (see speedmod kernel thread) he describes a method to manually deactivate H mode if you want to play with it.
Hope that helps.

seems to be the explanation... Suddenly I have ~6 Mbit, so almost unsurprisingly there had to be a catch
as for disabling H, it would be permanently so not quite an option. I guess, I'll have to live with it but nevertheless I'll call customer support..
Hspa and 3g are actually different technologies, but can be used on the same site and freq. If you have noticed that your phone is nowdays all the time showing H ( hspa ) and not in 3g like before it means that your carrier has expanded their hspa features and capacity of the network on that area. Main difference between these two tech is of course the speed and how network resources are shared between the users. In 3g you have dedicated ones, but speed limited and in hspa you are sharing the resources between other ones under that cell area. hspa is good if you are near by the cell and there is not too many users from battery consumption point of aswell from througput point of view, 3g is better if you are on the cell edge due to dedicated resources reserved only for you. Main point is, battery consumption of your phone depends mainly how you use your phone ,what kind of applications you have and how often those are connecting/contacted by the network.
Browsing in 3g sucks!
Sent from my GT-I9000 using XDA Premium App
Is this irrelevant or am I actually getting slower speeds? It's worrying a bit that I can't access HSPA.
HD7 uses "H", just doesn't show the "H" icon. Most service provider hide the "H" icon because it confused most customer who don't know about the different connections.
EDIT: There's an App that now has an option to show the 3G+ icon, aka H. So instead of seeing H, you see 3G+. The App is Advance Config & you need an Unlocked Device to be able to side load it.
Thanks DRF for the info. This thread was helpful as I had a similar question.
