Is there a way to force HSDPA? I have it enabled (using advance config) & rarely does it connect to it, uses Edge majority of the time.
if the place you are present have poor hsdpa support it
roam to other network types
would you rather have it loose connection ?
+1 on what Rudegar sad, also its BTS who decide for you when HSDPA should kick in. If you are in area you will recieve.
So theres no way to force the connection?
I had three bars earlier when connection & worked awsome, now Im on edge & fights to get 10kbps down. Ive noticed this in the cities Im in often like Roanoke,VA, Atlanta, Montgomery,AL, Virginia Beach, Detroit.

It's just like if you have a 56 kbps modem - remember those antiques from only 10 years ago - there's no way to force a higher connection speed without unreliability and connection drops coming into the equation. Maybe it's time to trial another network (perhaps with a pay as you go sim) and see how their offerings compare.
Where in Va Beach? I live in Va Beach and get HSDPA pretty much everywhere i go.

Like I stated above its the base station who opens up for you when you download or stream. You are not in HSDPA constantly as it does not enable until you do the above.

]I think that'll be very network provider dependent because where I live its always HSDPA irrespective of whether a data connection is present. Depending where I travel to, I have had cases where the connection drops to 3G but then as soon as I initiate a data connection it jumps up to H and I've had further cases where it's E or G and a data connection makes no difference.

Fast packet scheduling
The HS-DSCH downlink channel is shared between users using channel-dependent scheduling to make the best use of available radio conditions. Each user device periodically transmits an indication of the downlink signal quality, as often as 500 times per second. Using this information from all devices, the base station decides which users will be sent data on the next 2 ms frame and how much data should be sent for each user. More data can be sent to users which report high downlink signal quality.
The amount of the channelisation code tree, and thus network bandwidth, allocated to HSDPA users is determined by the network. The allocation is "semi-static" in that it can be modified while the network is operating, but not on a frame-by-frame basis. This allocation represents a trade-off between bandwidth allocated for HSDPA users, versus that for voice and non-HSDPA data users. The allocation is in units of channelisation codes for Spreading Factor 16, of which 16 exist and up to 15 can be allocated to HSDPA. When the base station decides which users will receive data on the next frame, it also decides which channelisation codes will be used for each user. This information is sent to the user devices over one or more HSDPA "scheduling channels"; these channels are not part of the HSDPA allocation previously mentioned, but are allocated separately. Thus, for a given 2 ms frame, data may be sent to a number of users simultaneously, using different channelisation codes. The maximum number of users to receive data on a given 2 ms frame is determined by the number of allocated channelisation codes. By contrast, in CDMA2000 1xEV-DO, data is sent to only one user at a time.

I was actually looking at that page a few days ago with regards to speeds but it doesn't change the fact that in some locations my phone shows the H icon when there isn't even a hint of a data connection present and no voice call taking place at the time either. Under such circumstances, it could have quite easily dropped back to a 3G icon until HSDPA is needed but it nearly always doesn't. The only place I've found it does work like this, interestingly enough, is when I'm going past the O2 UK HQ beside Slough train station where it will drop back to 3 G unless a data connection is in place.
When I was using Vodafone UK, this did not happen in the same loacation (never tested for this near their HQ out at Newbury) but again I experienced many cases where the H icon was shown on the phone but not needed. Thats why I've mentioned it's network dependant. I take your point that the specs dictate it should work otherwise but in my case thats not played out to be how it's gone.
If you want I can make your icon show a Q or Z for that matter, 3G as ONE a connection is a misleading term as it describes many technologies. Normal HSDPA suppose to show H when used and 3G idling. Remember the 6.1 ROM`s who displayed H all the time HSDPA or not? If you read up on wiki you will understand what I sad about HSDPA in earlier post. You cant draw conclusions based on what icon your phone is showing as the HSDPA technology will work as it always has.
So as long you do not stream/call of use for HSDPA you will not stay in it. So if you going to force it to stay in HSDPA you need to constant stream, an idle HSDPA connection swich over to 3g and back once called upon. So correct me if I am wrong here ... And I preferred documented. The only thing that is provider dependent here are if they support it and the coverage of it. The technology which I was talking about has nothing to do whit just that.

Why would my phone lie to me like that given (in the same locations) it reliably and correctly detects that it is in 3G and then when a data connection is initiated bumps up to H. There is no doubt to me that it is reliably detecting the connection type as it does this every time I travel through Slough on the train if I initiate a data connection. Similarly it seems as if the H, 3G, G and even E, do correctly display under the right circumstances. Again, I've no dobt about the HSDPA specs and how it should work, I'm just saying in reality with my HTC Official ROM'd phone (both using my current setup and previously WM 6.1), it's behaved that way in practice.
I think the OP wants the same sort of performance and indications from his phone that I'm getting from mine and I know no way to 'force' an HSDPA connection and get appropriate speeds if the network infrastructure and signal strenth aren't up to the task. On the other hand there maybe another network that operates much better in a given area which will provide whats required and there's little cost in doing some 'trialling' of competing networks in the areas involved.

There's no need to bring out the 'listen mate' with multiple questionmarks on the end. I do listen where I think something is clear and correct. If I think there's more to an issue, I chime in. In response to your link to that wikipedia page which outlines how it should work (in an ideal world), I'm telling you that some networks do not appear to implement things according to the official specs so it won't necessarily behave that way. My examples based from usage/observations in many different locations around the UK prove that point and as I mentioned that was also the case when I was with Vodafone here so that's all, no more, no less and no intention to offend.

I think it's best for the OP to make that determination whether my comments are relevant as we both replied in order to try and help that person out. You with some might say the 'official' line and me with the 'in practice' line. In the end we agree the answer as to what can be done to force HSDPA is the same ie nothing. I added the possibility that if better performance is saught, a network change may provide this.

Unfortunately bad news everyone. For some ungodly reason the Diamond is only showing G! Not even Edge! From what HTC is telling me they are only supporting 3G on the 2xxx Mhz band? That makes no sense whatsoever! I am willing to try things if anyone has a suggestion but so far not good! Which is weird because I previously reviewed the original Triband TYTN and that at least did get 3G on and off but always had Edge.
http://mobilitytoday.com/articles/htc_diamond_first_look.html
I don't know why you're not getting edge, thats a an extension of GPRS which works over GSM.
As for 3G/UMTS, it never said it suported anything but 900/2100. There's nothing you can do, HTC already said that there wasnt enough space in the phone for the extra antenna's required to support more frequencies.
isnt edge on 1900 ?
yup it is! I would be willing to look into the registry to see if there is a tweak? Any of you have an idea?
no idea my guess would be try forcing 1900 ?
beyond that i wouldnt know
try different area ?
Edge in the US in most areas is 850Mhz, which is the reason I held off on my purchase of the Diamond.
hmmm
interesting but i had bought a original touch in india and that works in most places that i go in the states and i recieve edge

so dave did u get an hsdpa signal?
and im sorry u in jersey or nyc?
i forgot
sorry but is there a reg edit where he could force the device to look for 850?
just to see if its hidden..then we can find out if they really left out the radio or not...i really wanted to pick one up ...but if it doesnt have 850 its a no go for me...bummer

Mine does show the 850Mhz band but thats not the problem the problem is that this phone ONLY supports 3G at the 900 and 2100mhz band.
The UI is very laggy so far. I am going to use it via Wifi and see if that improves the UI. BUT another weird thing is that I just popped my Tmobile sim in and now get Edge?

For those who are interested I just posted my first day video feel free in checking it out..
At the begining of your video you say that while a GPRS connection is up your calls go to voicemail? Thats not normal behaviour:
Class A devices, which some new devices are, can make/receive calls without dropping the GPRS connection. Just to be clear, data can still be sent/received over GPRS while you're talkiing.
Class B devices, which all other devices are (except the first few GPRS devices made), can handle GSM and GPRS at the same time, but will drop the GPRS connection while a call comes in, or you make a call. They then resume the GPRS connection after the GSM channel is not in use.
Class C devices, can only handle GSM or GPRS one at a time, and you have to manually switch which mode you want. Only the first few devices ever made or Modem terminals are Class C.
Are you absolutly sure about that behaviour because its not a defined class for GPRS.
PS. best quality video so far. With that great lighting you can see exactly how the 'diamond' is on the back. I think the fact its brand new and super clean also helps
Also it seems significantly faster than the coolsmartphone review.. I guess the extra RAM makes a huge difference.
Has a date been tossed around yet for a possible US friendly version launch? Or is this just another one of those cool phones we won't get to use over here?
I am in the USA .. no phone with only GPRS or Edge can take a phone call while in a data connection.. Only 3G can do this in the USA..
Thank you very much for your kind comments about my video.. We try very hard to deliver a good review. I will continue posting more videos as I continue to use the Diamond.. So far for me this phone in the USA is a dudd..

well i hate to say it but you should have read up on the specs before you bought it, the phone itself isnt a dud. The DIAM200 will work on 3G 850Mhz in the states and will be released in a few weeks
This thread is only for users that are UK T-Mobile customers that have only basic Web N Walk. In fact it might only apply to customers that have moved over to Web N Walk on or after January 2008
I have noticed that my download speeds seem to be teetering at the lower end of 3G, slightly better than GPRS, but no way near HSDPA speeds. The test is located at the following site, if you are unable to use Opera try Pocket Internet Explorer.
www.dslreports.com/mspeed
I have repeated this test at various points throughout the day and with various signal strengths and have never been able to download faster than 190kbit/sec.
I have been speaking to T-Mobile regarding this issue and they state that HSDPA is only available to Web N Walk Plus customers and not the basic Web N Walk customers. However, colleagues of mine are on the basic Web N Walk and are able to download at HSDPA speeds.
T-Mobile are unable to provide written proof stating that HSDPA is unavailable on basic Web N Walk, the terms and conditions do not state this, and the 1GB fair use policy should ensure no one abuses the additional speed.
Furthermore, the MDA Compact IV is sold as a HSDPA enabled phone. I therefore conclude that either I have been miss-sold my contract / phone or T-Mobile have incorrectly disabled HSDPA.
What I would like to do is see if others using the MDA Compact IV are in the same situation, so could you go and do the above test if you are a UK T-Mobile customer on basic Web N Walk and report back on what speed you get.
My HSDPA connection is patchy at best, in that the coverage is poor (as is T Mobile in general). However I have just tried the speed test and I got 1157 mb for a 1 MB file. Doesn't really seem representative of my usual speed experience though.

Are you on the basic Web N Walk tarif and when did you move over to it?
Whoever told you this about HSDPA at certain tariffs on T-Mobile is talking tripe I'm afraid. HSDPA is standard on T-Mobile 3G across the UK now, as is HSUPA UK wide and in London area faster HSDPA.
I'm sure you know that the figures are published at best and you will rarely hit what they publish.
In my area I get a four bar signal but at best I get just over 1mb connection with it usually being around the 300-600 mark. Uploads however have seriously improved since the network upgrade a few weeks ago.
I'm on £7.50 w'n'w and the most i get is 300kbps which is the same as when i turn off hsdpa and just use 3g - still 300kbps.
What the hells going on?

Right this is FACT and it IS on terms and conditions, I read them.
The reason I aborted my pre-order of MDA Compact IV was (amongst others) the fact that the standard web n'walk IS 3G speed only at up to 384kbps.
When I found out I flipped and cancelled and rang Orange retentions and got such a blinding deal I stayed with Orange ! Orange = HSDPA any package.
T-Mobile customers in the UK who have been on web n walk basic for ages may be under old agreement when it was HSDPA. You have to be on wnw PLUS now to get HSDPA for new customers.
dont get it, whats the deal? Why not pay another 5 or so quid and have HSDPA?
Afterall, why do you need HSDPA if your just browsing on your phone???? The only real reason you need HSDPA is if your using your phone as a modem which basic package doesn't allow you to do anyway.
This just makes sense.... so, whats the problem? Its not like its 10's of pounds of diference, its the price of 2 pints in a pub?
HSDPA is useful for web browsing simply because the pages load up up so much quicker.
I use mine to do a bit of browsing on the train after leaving work, and the difference when the coverage drops off to standard GPRS along the journey is very noticeable.
To say that you don't need hsdpa for browsing is like saying we could all make do with 56k modems for browsing at home. Yeah sure we could. but it would be painfully slow.
I am on T-mob, but have the HTC version. When I first got it there was no hsdpa on my account. when the phone detected a hsdpa signal, I could not connect at all, so I phoned 150 and asked the guy to make sure that hsdpa was enabled for my account. He said it should be but he would check. When he checked the system it wasn't set up, but he enabled it there and then, and it was available pretty much straight away
I am on flext 20 + w 'n' w basic
I'll try the dslreports thing tomorrow, but pages do load up much quicker when I have a H signal indicated
GPRS is commonly known as 2.5g
3g is "3g"
HSDPA is commonly known as 3.5g
Speed limits for each
btw: i'm fairly sure the phone supports HSUPA with a quick registry setting. Remember also that HSDPA is a BURST technology, not a sustained/constant technology.
Just because you dont have a "H" in your bar, doesn't mean your getting slow speeds - 3g IS quick enough for webbrowsing. You get normal 3g connection on Web'n'Walk basic.
So my question still stands, why do you NEED 3.5G HSDPA speeds for webbrowsing when 3G (Normal) IS way fast enough? If I was T-mobile I would use the same method for discouraging people using the phone as a modem when they are not supposed to - mind you 3g is still waaaaay fast enough for most stuff.
The fact you couldn't connect when your phone shows a H in the bar is odd... glad you got that sorted out.

I was on the basic package, I have not requested to move up neither have I been told that I have been moved up. The potential difference here is that I was on web n walk before Jan this year.
Good luck in trying to sort this out. i've decided to go (back) to Vodafone at the end of my contract in Nov because T mobile network coverage is so shocking.
did a few speed tests on mine this morning:
on the train
GPRS - 37 kbps
HSDPA - 498 - 1514 kbps
at my desk
HSDPA - 778 - 1231 kbps
was on web n walk basic for two years before upgrading to the diamond
and your trying to tell us 37k/s isn't fast enough to render webpages? If your experiencing slow webpages with this speed, its not your link at fault.
edit: at its at least 3x faster than you could dream of on a 56k modem!
Everyone who has responded so far has been on the Web N Walk package before Jan 2008. I would like to hear from someone who has only recently moved over to Web N Walk.
@ Monty Burns
1. There are better was to ensure that Web N Walk basic customers do not use their phone as a modem, such as a fair use policy, which they have. Why restrict how fast someone gets to that 1GB limit!
2. Yes back in the day 56K seemed fast, but you got to understand that the bar is constantly moving, back them most pages where static HTML, these days we have java, video streaming, audio streaming, not to mention bandwidth intensive apps such as Google maps.
I do notice the difference between what is effectively 3G speeds and WiFi. It’s frustrating and T-Mobile should see common sense and allow everyone to use HSDPA, it doesn’t cost them any extra to do so.
@ ns73
Please point me in the direction of the terms and conditions you read, as I cannot find this anywhere!
yes your correct, the bar is higher but .. why do you need 3.5g to do it? 3g is way fast enough and will happily fill up your phone very quickly!
I suspect there is some form of limitation to HSDPA connection/s which is why, if i was t-mobile, i would limit it to those paying for the full package. As your only supposed to be browsing, you just don't need 3.5 when 3 is still massive overkill.
I remember few years ago when HSDPA just came out I rung up T-mobile and they had to tick the box for HSDPA enabled. I believe you can also do this yourself by logging into the T-mobile website and managing your account
You don't get HSDPA with standard WNW, and while it may not have been stated when you connected, it was also not stated that you WOULD get HSDPA. If you connected to WNW over a year or so ago you may have slipped the net, and still have access at the higher speed.
As far as "ticking a box" is concerned, I don't believe this option is still present on their' systems, and even when it was it was simply for legacy purposes and you should have never have had it ticked in the first place.
The £5 isn't much extra to get the HSDPA, I don't mind paying it.

Exactly. Cough up and get the larger packet (about 2 beers a month!!!? If you can't spare that, you have more serious concerns), live with no HSDPA (why do you need it anyway when your not allowed to use it as a modem) or go to another telcom.
well i've just taken out my compact IV on tmobile, flext 30 with W+W my signal at home is shocking, but at work connects over HSDPA and returns between 992 and 1324 so far, just with standard and new line taken out on tuesday
@ Monty,
I have to disagree, while you may feel that 3G does fill your screen quickly enough, I find it slow and tedious. Everyone is going to have their own opinion on what they consider to be acceptable. I do not consider my current browsing experience to be acceptable.
There is a limitation to the number of connections per cell station. The cell station has algorithms built in to automatically share the data between HSDPA, 3G, GPRS, and GSM. However, this ratio is adjusted every few milliseconds on the fly and would only be a factor if a large number of people are downloading at the same time.
@ lx_t,
This option is no longer available on the T-Mobile website.
@ OK!
Your right WNW basic does not state that it includes HSDPA, but neither does any of the other WNW tariffs, so in that case as its not explicitly stated one way or the other, it is implicitly implied. Furthermore the MDA Compact IV is sold as a HSPDA phone, it does not state that this is subject to being on a particular WNW tariff.

Thats not the link. you cannot notice the diference between 3g and 3.5g on a web browser on your phone... unless the web page has tens of links to some seriously high megapixel pictures of course but then, the phone would cave in anyway.
Check out the link i posted above for the speeds. 3g is like using a ferrari to race a push bike when it comes to speeds needed for web pages. HSDPA is designed for "modem" use and heavy downloading and for web browsing is like using a Veyron.... if you think 3g isn't good enough, your never going to be happy with web browsing on a phone.
I've spent more than £5 pounds worth of my time trying to explain this and thats all it would cost you a month to get a little more priority on the t-mobile network and a higher fup. Why are you so cheap? Why should you get maximum speeds on cheapest package? its FIVE pounds.
Now, where's the nearest wall, i think it might be less painfull head butting it than this thread ....
I recently installed the eOS 4.888.FiRe ROM on my Tilt and it has been working nicely. I noticed some additional settings that weren't available to me when I was using the stock HTC ROM. What is "HSDPA" and "AGPS"? And will it cost me to leave these turned on? I notice when I turn on HSDPA, I see a an "H" icon at the top rather than the usual "3G" icon.

What is "HSDPA" and "AGPS"? And will it cost me to leave these turned on? I notice when I turn on HSDPA, I see a an "H" icon at the top rather than the usual "3G" icon.

what is google???
anyways simple answer:
hsdpa is a form of data connection which is faster than 3g.
agps stands for assisted gps. it is same as normal gps except that agps uses a server to cut down on the time to requires to get ur location using gps.
both won't cost u anything extra but ur carrier does need to support them for u to be able to use.
Thank you. I just wanted to know if they both won't cost me anything extra. You never know these days with Cellphone companies. I turned on both HSDPA and AGPS. So far my calls have been going through just fine and my navigation software continues to function normally.
How do I know if my carrier (AT&T) supports HSDPA and AGPS? I hate having to call customer service to ask so I'd rather ask here.

I used KaiserTweak to set my phone to HSDPA. I am an AT&T user. It's worked fine. No additional charges. I don't use AGPS so I can't respond to that part of your question.

Thanks for your response. I just use it for voice calls anyway. Do you see any improvements? Or is it specifically if you subscribe to a data plan? And do you also see an "H" icon at the top rather than a "3G" icon?

HSDPA has to do with you data connection, so unless you have a data plan you really won’t see the benefit.

HSDPA doesn't cost anything to activate, but if you are on a restrictive tariff it is a lot easier to run up over usage charges.
In the UK you need to usually be paying at least £30 a month to have the unlimited mobile broadband and e-mail. I would personally check your contract before you let the HSDPA run loose.

As mentioned multiple times, neither HSDPA or AGPS will cost you anything. You will know if you are in an area that has HSDPA because of the H icon. If it goes back to 3G then ATT does not have HSDPA in that area. If it goes to E then you are back on Edge. As also was mentioned, neither of these have any impact on your phone calls. HDSPA = Data and AGPS = using the cell towers or the internet to help you lock on your GPS location quicker.
And yes, if you had used google to search for this you would have probably got a better explanation in a less amount of time.
Hi all,
I've got the following problem with my XDA Diamond (O2 Germany).
- To establish a connection, first the 3G connection is enabled. After the 3G connection is up, it switches to HSDPA ("H" icon).
- Now everything works fine, no latencies and fine transfer speed.
- After a certain idle time (surfing...), the H disappears again and is exchanged by the 3G.
- When I try to download data again, it switches back to "H".
=> Then, huge latencies occur (up to 1 min. before data are received), the connection speed slows down dramatically or no more data is received at all.
I first thought of issues with my ROM (Bepe 0.99) or my RadioROM (.05). But after flashing to Aztor V7 and RadioROM .08, I'm afraid I have hardware troubles as the problem persists.
Now my questions: Did anybody here have the same problem? If yes, could you fix it? If yes, how? ;-)
Would be nice if you could help me. It would be really annoying to RMA the device...
Thanks for your help in advance!
Regards,
eypostel
That could be because you device disconnected from the net (thus it switched from H to 3G), and it take time for it to reconnect to the net.
Thanks for your hint, but I think this behaviour is not normal...
Even the connection cold start (establishing 3G connection, then switch to HSDPA) is faster and before, the connection was working fine:
When in 3G mode the connection was required, the icon changed to "H" within one second, and the data transfer started immediately.
Now, it takes about ~30 s before the first life sign, and then data reception is not even guaranteed.

eypostel

Thx prodigy7, this topic exactly describes my problem...
I have a question regarding this HSDPA idle bug. Turning off HSDPA should bring relief, but my MDA Compact IV does not have the HSDPA-switch. Can anybody have a look in their registry which values are changed when HSDPA is switched off on an XDA or HTC device?
It is easy, simply save a copy of the registry with PHM RegEditor before and after the change. Then compare both files with a file comparison editor (PSPad or TotalCommander for desktop PCs does the job).
This is so ridiculous... I have bought a HSDPA-device (Touch Pro) because I wanted to use HSDPA a lot... and it doesn't work at all... this was my first and last HTC device... I have invested 600€ for a piece of crap.
The Diamond does HSDPA just great, however your service provider must support it. In the UK T-Mobile supports it on their Web 'n' walk Plus and Max services. If you have normal web 'n' walk you can see the H and connect using HSDPA but its throttled.
Nothing to do with the device, just the service provider. It also depends on coverage. For example, when at home I get a H with 2 bars. When driving to work I loose that and get 3G and then eventually just G. Because my provider doesnt have HSDPA coverage where I work.
To turn HSDPA on and off easily use a cooked rom, i use Duttys. Very close to the original and tweaked just a little.
Did you read the german thread linked above? I guess not because what you wrote is wrong.
It is correct that the problem only exists if you use htc devices in the O2-HSDPA-Network. But: the problem only exists with HTC-devices in the O2-network. I am able to use any other (non-HTC) phone that supports HSDPA with the same sim-card successfully in the O2-network. And I am also able to surf using HSDPA with my HSPDA-Surfstick in the O2-HSDPA-Network. This means: the problem is not the network, it is the device (=HTC).

If it was that simple then none of us would be able to use HSDPA on our TD, but most of us can. I can use it on my TD on Orange in the UK and other networks including O2 when I am roaming in Europe and, for that matter South Africa (not sure about Germany). So the problems probably lies with the interaction between them, rather than solely the "fault" of one or other.
Seriously, sometimes people can be a bit absurd. 3G & HSDPA are standardized communication protocols. This means that there can be little (no?) device-to-device OR network-to-network variation with regards to the integral working of 3G. The context and application might vary and impact performance, though. For instance if a device is not supplying enough power to its 3G chip, signal acquisition might be slow and strength weak.

I highly doubt the existence of a bug limited to a single network and device brand. By the way the Qualcom chipsets (which incl. the 'radio chip') are not specific to HTC and many companies (incl. Kyocera, Motorola, Sharp, Sanyo, LG and Samsung) feature them. The specific Diamond Qualcomm chipset (MSM720xA) also features in the G1, Xperia, Motorola Atilla & Alexander, LG Incite and MANY others.

I seriously doubt that. To prove this, you would need to test EVERY single 3G phone that has ever existed with the network. Which is, quite frankly, impossible.
Like I mentioned earlier (ct. 1st paragraph) context and application might influence performance. Maybe you're just not in an area with sufficient coverage, maybe your specific device has a design flaw or malfunction. Whatever the problem is, I'm pretty damn sure that it's not "HTC-devices don't work on O2".
I use the german o2 internet pack L and I have the same problem. Seems to be an o2 issue.

That is a much more feasible scenario. Any other O2 users have this problem?
I totally agree with H3x. You say the problem is only HTC devices on O2 so therefore its a device problem. but surely as the problem only exists on O2 its an O2 problem? Every other network in the world seems to be fine. Did you test any other devices with your SIM and network or are you just reading whats on the internet and taking it as true. As we all know, the interwebs is never wrong.
But, your obviously not happy with your diamond so throw it away, go and buy a nokia.

Seems like the HTC-homies in this forum are not willing to read what I wrote before and keep asking the same stuff again and again. I mean, I wrote in the previous linked post all details that you are asking again here...
I'm outta here and will keep at the german forums where people are not constantly trying to convince me that I am stupid...

You're right of course. The bug mentioned here is not limited to a single brand nor a single network. But it seems to be limited to specific Qualcomm chipsets. According to numerous reports in German user boards all (?) devices using MSM7501A (HTC Touch Diamond, Touch Pro), MSM7200A (SE Xperia X1) and MSM7201A (HTC Touch HD) have trouble reconnecting from HSDPA-idle in German O2 network. Doing some research on the web I found similar reports from Swiss Orange users.
From my experience as a German O2 user: An idle HSDPA connection switches back from "H" to "3G" after 25 seconds. If you then send a new request, e.g. tapping a link in your browser, the connection indicator of your device changes to "H" again, but most of the time the connection hang up. You have to manually disconnect and reconnect... Switching off HSDPA/HSUPA gives you a stable 3G connect, however limited to basic 3G speed. Another workaround is to frequently ping around, a 10 to 15 second intervall does the job. With pushmail or some IM messenger active it may work, too.
That's my experience with the SE Xperia. And it's definitely not a local network issue nor temporary - I'm using a Palm Treo pro, too, without any problems at all. AFAIK the Palm also is a HTC device running on a Qualcomm chipset, the MSM7201 without an "A".

I was having issues with poor latency/delays and slow connection speeds with TMobile. I called them and they said even though prepaid 4G doesn't have data roaming, if you have data roaming turned off on your phone, it won't get full 4G speeds. I didn't believe them but decided to try it. My speed went from 3mbps to 13mbps! I then had a friend (on an HTC One S) do the same (he also had data roaming off) and he saw the same boost in speed!
** IMPORTANT: for this to work properly with the network, you need to reset the APN to default after turning on data roaming.
(They assured me that we won't get charged for data roaming because the account doesn't have that enabled for other providers)

I tried it, but didn't notice any difference. Why don't you give it a try?
Just did it... not sure if placebo or not but I seem to be getting a *tad* bit better signal in my office (which is usually a blackhole)
yeah.... placebo.
If anything, resetting the APN would impact things as traffic for various APNs gets handled differently and may result in lower pings or higher speeds.
For the most part though, the only thing that affects pings on a handset that you have any control over is the radio firmware being used or the handset reception due to how you hold the phone. The rest is regulated by the load on the cell (tower) you're attached to, backhaul supporting the tower, and the APN you're using which directs traffic appropriately through the network.

You got handed a sugar pill..
Data roaming, affects "data"... It wouldn't make the difference to your signal bars. Signal fluctuates way too much to even compare, even standing in the "same" spot, holding the phone with the same hand facing the same direction...
Thanks for posting this. Normally my speeds were 0-1.xMbps but after trying this I've gotten 6.87Mbps down on my 1st test.

getting H instead of 3g affects data, no?
