How do I tell I'm using HSDPA?

Hi, I'm aware that my UK T-mobile Ameo is HSDPA capable and I think I'm in a HSDPA covered area but the homescreen only ever shows a little 3G symbol (or a GSM symbol when I'm not in a 3G covered area).
Is there a way to know whether I'm using HSDPA?
I guess one way would be to do a download speed test - anyone know a convenient way to do one?

If you were using HSDPA, the 3G symbol would change to an H.
However, if you only have the £7.50 web and walk package, and only signed up after the summer, you do not have HSDPA on your account.
The £12.50 and above tarriffs come with HSDPA automatically, but for the £7.50 plan, you need to ask for it and hope that someone likes you enough to add it.
By the way, On T-mobile, you will not see the H all the time. It will only appear when you are transferring data. At all other times you will see the 3G symbol so that you are able to receive calls. If you are transferring data on HSDPA, the T-Mobile Uk network will force you down to 3G while the call is routed to you, and then jump back to HSDPA when the call ends to carry on downloading.
T-Mobile is the only network i have seen that does this properly.
Also, T-Mobile has gone HSDPA on all of their 3G transmitters. If you get 3G coverage, you definitely have HSDPA coverage, but you don't necessarily have permission to connect at HSDPA speeds.

Agreed, you will see the H symbol instead of the 3G signal - I am on O2 and it works fine (you should also see an E to show an Edge connection where available).
The point about tariffs is one for you to take up with T-Mobile.

Make sure the HSDPA checkbox is checked, in Settings > Connections > HSDPA Switch. When I'm in a 3G area and I start downloading something, the 3G symbol temporarily changes to an H symbol, then changes back to 3G when done.

Do you see the H all the time, or only when you are transferring data? I know that on some networks that have an old revision of the HSDPA software, it can cause issues with receiving calls if you are on HSDPA the whole time. Have you had any issues with this?

Firstly, you will only see an H if your ROM has different icons for 3G and HSDPA. Some do some don't. If the ROM doesn't have that facility, the 3G icon won't change even if you are occasionlly using HSDPA. As far as I am remember, some of the stock T-Mob ROMs do not include this.
You do not AFAIK need to ask T-Mobile for HSDPA. I have never asked them and regularly used it. I am on a £7.50 plan.
There are plenty of speed test sites out there - Google 3G speed test.

Another good site to check speed is "http://performance.toast.net/default.asp?allservers=1&checkid=" I usually check the "Text" box and try a few hosts...TJ

Only when data is transferred, the 3G symbol is there most of the time.

always been seeing the H on mine, right from the original T-Mobile UK ROM. All Windows mobile 6 ROMS from HTC include the different icons, and unless the operators specify to take them out, they should always be there.
the T-Mobile ROMs do include the different icons, as do all the AP ROMs.
Sometimes you DO have to ask T-Mob for HSDPA. They originally turned HSDPA on for the £7.50 contracts by default. They changed this standard policy sometime last year (as i stated in my first post, i think it was in the summer, but i'm not sure) and now not everyone has HSDPA on their contract. If you ever see the H you do...if not, you don't.

Very slow HSDPA

I am connected to T-Mobile Internet (HSDPA) and I ran a speed test at www.dslreports.com/mspeed but I only got 395kbps, 0.324s latency. Why so slow?

That speedtester is rubbish - I once got 250k on wifi.

can you recommend a better one?

i've just found out that t-mobile doesn't activate HSDPA unless you call up CS and ask them to enable it. some people have been told that you have to be on web n walk pro to have HSDPA whereas others have had it added free of charge.
http://www.3g.co.uk/3GForum/archive/index.php/t-45508.html

but one thing is still confusing me... the H is displayed at the top of my screen when I use the data connection. and when I click on it it actually says HSDPA. what's going on?

try http://www.thinkbroadband.com/speedtest.html via your laptop. much better and accurate

if you have the H - then you are def on it. If it was just 3G it would say 3G. But bare in mind that T Mobile HSDPA has been dreadful for nearly a month. It gets so bad that I am considering asking them to release me from contract for violating terms of service. I pay for HSDPA as advertised and I dont get it.

I had web&walk previously and I managed to get full speeds for a while. Once I have reduced my call plan(not data) the speeds were down to 300kbps and less. On these occations, I would still see H as the indication but sure they were capping it on the network.

reopening old thread
I've got H and my provider allows speed up to 7.2/2mbps, but for long time (few months) testing I never get speed higher than about 2.4/0.3 Mbps. I've tested on computers via USB cable and on two different locations both about 500m from antenna.
My provider say that I have all set up correctly and doesn't know why speed is 'so slow'.

Nearly everywhere 7.2mbit hspa is a myth - the only way you can get it is if nobody else is using the celltower.

A very reliable speed test application is: http:www.mobilespeedtest.com.
The dsl.reports app (on my HD) provides non accurate results.

The more people using a HSDPA or 3G celltower - the slower your speeds get.
Trust me - I've done all the testing from a corporate perspective - HSDPA 7.2 is a myth - you'll never get that speed - its more like 3.2mb/s MAX!. On 3G the average bandwith is about 300kb/s - but only on a good day.

I'll test and report tonight, when I'm on a good HSDPA signal covarage!

yo compatriot , have you manage to test the speed yet?

With www.mobilespeedtest.com it managed to get 3Mbit downstream in Ljubljana-Vič, haven't tried Centre yet. For normal browsing and download of some small files it's ok. I'll report if I get better bandwidth!

With www.mobilespeedtest.com:
- I get a 2.37 Mbps speed test result on the 3 MB file(biggest) while connected from my mobile to a HSDPA 3.6 network which allows for a max 1.1 Mbps speed.
- I get a 2.4 Mbps speed test result from my computer while connected on a 15 Mbps ADSL - yes - I do 1.7 MBytes/sec transfers all the time - careful at the units of measurement!
- on smaller than 3 MBytes file size, the results are just random
www.mobilespeedtest.com is FAKE
The flow of the web pages has been so severely thrashed by ISP filters its not reliable to real testing anymore.
Stop.Calling.Any.Web page.A.Speed.Test.
Ping flood is designed for real measuring a line speed, but most ISPs have scripts which will ban you automatically if you sent packets faster than with a delay of 0.02 seconds. That is because is too much prone to abuse.

Checking HSDPA

Hey, I've got a (rooted) G1 on T-Mo contract.
I want to check if I'm getting the fastest internet I possibly can. I know Haykuro's build display an 'H' instead of 3G if you're on HSDPA, but I'm using JesusFreke's latest cupcake build and it's my understanding that that doesn't.
So the question is, how can I check whether I'm getting real super wow omg 3.5G internet (which presumably I can, living right in central London) or just the regular 3G?
I've wouldn't normally think twice, but I've read lots online about having to enable it and there seems to be a lot of confusion. Also, it would be nice to know when I'm on 3G and when i'm on HSPDA, given that JF's build (kickass as it is) doesn't include an icon for it.

download xtremelabs speed test from the market. then check your max speed against max 3g and min hsdpa speeds that you have since googled to find out. while on haykuros rom, i got the h icon and i have full 3g coverage here in kansas city kansas.

Ilm in the same boat at the moment. When running Haykuro's H build I have H on Orange UK, the about status of the network says Ilm running on HSDPA but nettraffic says I have no connection speed unlike UMTS (won't work in other words).
I'm currently on JF's ADP1.5 rom based on htc build and only get UMTS. It would be nice to be able to have HSDPA but UMTS is fine...

Hey aad4231, thanks for your reply...
I'm a little confused, I thought UMTS utilised 3.0g services whereas HSDPA uses 3.5g? When using JF, T-Mobile or Haykuro's G build the phone uses UMTS according to system information and netmeter and nettraffic. When I use Haykuro's H Build GPRS comes up, then UMTS and finally HSDPA. Data services work while on GPRS / UMTS but as soon as HSDPA comes up there is no connection speed in system info.
I'd love to have HSDPA speeds (with Orange UK I believe it's 3.6mbps or smthg) rather than UMTS as I use my G1 as a mobile router with Wifi-Tether.
Thanks in advance again!

Run a speedtest (e.g. http://i.dslr.net/tinyspeedtest.html). If your downlink is greater than 384kbps, then you have HSDPA.
As been mentioned above, just because you do not have a H icon doesn't mean you are not connected via HSDPA. The H icon is present only in Haykuro HTC build because HTC added extra icons to indicate whether a 3G connection is HSXPA enabled or not. However, that does not mean that standard Dream software cannot connect via HSDPA. It does, but it will not indicate it. Again, confirm with speed test.

Just done a speed test using Xtremelabs speedtest from market. I noticed I'm now getting 843.5kbps since I flashed my G1 with JF's ADP1.5 last night. Prior to this I was only getting about 320kbps on JF's RC9/RC33 Builds.
Thanks for your quick reply and sorry for having to get you to explain again.

Thats pretty impressive, but as far as I know the different versions flash don't effect the speed. I believe that has all to do with the radio. Did you update your radio, that may have something to do with the increased speeds?

Actually the most likely scenario is just moment-to-moment variation in network usage. Packet-switched data services are usually delivered on a "best effort" basis. If you check the bandwidth at different times of day you will probably notice fluctuating numbers.

Yeah, Flashed the Radio with HTC's 1.5 from their Dream website. I do notice that speeds vary though throughout the day. In Mid-day I get about 400mbps but hadn't got 800mbps+ before, even in the evening.

Hot damn, it must be a low traffic day here in AZ. I just pulled down 1062kbits/s.

I just noticed that it says your network type on Settings>About>Status, so you can get an easy definitive answer rather than just running a speed test. Also has battery level which is nice. I made a homepage link to it on anycut for easy access

HSDPA or 3G speed?... I go crazy!

I have a question regarding the HSDPA on the TMOUS HD2. I used a Diamond back in Germany and when I was in an area with HSDPA reception it was indicated by a "H" in the taskbar. Now I am using the HD2 in Baltimore. From what I`ve read there should be HSDPA available arround here (especially since I am in Downtown B`more) however I only get the 3G symbol in the taskbar. I have also been in DC over the weekend and it was the same only 3G. But I am quite sure they have the HSDPA network available there. Does that mean my HD2 doesn`t get the faster HSDPA speeds at all?
I did a speed test using mobilespeedtest.com and IE.8 teethered WiFi connection on a Windows 7 system. My results in Downtown Baltimore are: "Your speed: 1428.571 Kbps Your latency: 0.561 seconds Transferred 100 KB in 0.56 seconds". With a 4 bars 3G symbol instead of a H in the taskbar. Aren't this speeds you would expect on a HSDPA network? I am running the original stock ROM on my HD2 by the way.

I am pretty sure most carriers use 3G with hspda enhancements, aka 3.5g, which would allow the speed above 3G's cap (364 kbps). As far as why your phone states H instead of 3G, it is dependent on the phone and icon set your phone uses. Some roms will show 3G and others will show H.

where do you find the HSPDA settings? I know they were somewhere but I can't find them!

I think the 3G/HSDPA is weird on the HD2. I can sit in one place and watch it change from Edge to HSDPA without moving the phone (and sometimes a random 3g will show up).
It definitely sounds like you have HSDPA since those are some nice speeds. Mine says 'H' and I get around 780kbps, so you're double that. As long as you have a fast data transfer (and you do) I wouldn't worry =)

I was in Las Vegas Convention recently, and witnessed the power of HSPA+.
HOLY CRAP. Why can't we have that speed ALL over the world?

I was always under the impression 3G was better than H. Perhaps it's a good thing then that mine's usually H then! Where does E fit into the speed scale?

E = Edge. the slowest.

actually GPRS is even slower than EDGE
if i remember EDGE = 500kbps
GPRS = 360kbps

GRPS = 2G
EDGE = 2.5G (sorta)
3G = 3G
H (HSDPA) = 3.5G

Poor internet on Telstra Australia

I have had my SGSII for about 6 weeks now. Running it on the Telstra Next G network.
The problem is I am having a shocking internet experience.
My experience is based after coming from the HD2 running Android.
I have had the network freeze a few times. This is identified by the traffic arrows stay stuck. Airplane mode and back resets.
Basically cloud based apps like Market, Maps etc takes ages (60s-5mins) to start up. Kill and re-launch is quick).
Lots of network errors in Google Market.
Lots of Server unreachable errors in Emails (Pointing to exchange 2007)
I have updated the APN details to use Telstra.internet.
Great reception at home and work.
Calls and SMS's are fine.
Ideas? Waiting to see the Cyanogen rom. Wondering if my experience is due to Kies or another program getting involved with internet.
Any ideas please. My HD2 ran with the same Sim and worked like a rocket. No such issues.

Have you tried turning fast dormancy off? I'm on the Optus network, but I found with fast dormancy on I was getting unreliable internet (market would timeout a lot, doing installs/updates would fail straight away, etc). When I turned it off, I got better speeds and the connections were reliable.
Turn fast dormancy off:
1. In dialer - *#9900#
2. Select Disable fast dormancy

no such issues for me, using a vodafone branded handset. The only thing is that it will occassionally use 3telstra instead of telstra, in which case i need to manually select the network. a bit of a pain but not 2 bad

****************** FIXED ******************
After contacting Samsung for an insane period of time (ended up on an international call to England i think... or now that i think about it could have just been some English guy in Aus lol) I have got an official explanation and confirmation that this issue is being looked into for KE8 (but it appears that KE8 has been launched in India already so it might be KE9).
*disclaimer*
I am no expert on mobile technology this in-depth however the (probably very) dumbed down version the Samsung guy told me was this;
*end disclaimer*
The problem stems from the fact that this phone has 3 forms of data connection, 3G, HSDPA, and HSPA+.
3G is what we have all had since 3/Telstra launch 10 years ago.
HSDPA is the 7.2mbps connections that we got after that.
HSPA+ is the full fledged 42mbps Next G stuff that only Telstra has.
The problem is, when you are just using the phone as "a phone" it idles on a 3G connection to save battery and when you initiate a data connection it flicks on to the higher connection protocols for better speed.
What is supposed to happen when you initiate the data connection is the phone checks for H+ connection, then for H and then finally 3G. For some reason if you arent with Telstra or are in an area without HSPA+ the phone gets hung up for too long attempting to initiate the H+ connection and refuses to drop back to H!
Also, even if it does give up on H+ it then has an issue with falling back to 3G. Resulting in the problem that if it cant get H+ or the tower is too flooded for a H connection you get absolutely nothing until you restart the data mode within the phone, renegotiates with the tower and BAM, you are back in business.
So... there are 5 fixes;
1. Wait for KE9 (or what ever firmware fixes the modem timings etc)
2. Get a Telstra sim and never leave an area that has H+
3. Turn off/on data mode whenever it happens
to which i told him they were stupid answers and completely unacceptable, but then he came out with this complete gem!
4. using service code *#301279# you can turn off HSPA+ completely forcing it to start the data connections on HSDPA
5. using *#301279# again you can just turn off HSPA+ and HSDPA meaning it instantly starts downloading the data on 3G without delay
Now yes, i thought... great... ive bought this $779 phone that has all the latest and greatest technology and I cant even use it! But, I did some testing!
First of all my normal sim is Vodafone so turning off HSPA+ is an obvious one for me, im never going to get it so why bother. So now that the phone only attempts to get a connection with HSDPA the need to turn off and on data connection was getting more and more rare but still having the problem (i have a feeling that is due to congestion?). So i bumped it down to 3G only and it works perfectly 100% of the time!
The point of these faster connection protocols is speed so i did testing.
Vodafone sim, 4 bars of signal in the middle of a shopping centre.
HPSA+ turned on = 4mbps down, 1mbps up
HSDPA turned on = 4mbps down, 1mbps up
3G only = 3.5mbps down, 1mbps up
did this over and over and over again and to be perfectly honest, im willing to lose 500kbps to make sure that data always works and if you are just doing general web browsing the time it takes to initiate the HSDPA connection wastes more time than the slightly slower speeds with 3G does.
Now obviously this only works fine in my situation, if you are with Telstra and going from HSPA+ down to 3G means going from 20mbps to 3... i would be pissed. But for the rest of the country you are talking about a loss of less than 1mbps so in real world situations with just small amounts of burst data its fine
TLDR; Try and go online and the 3G up arrow lights up but never actually downloads anything
Dial: *#301279# – Change HSPA revision – Release 5 HSPDA only
test, if still a problem
Dial: *#301279# – Change HSPA revision – Release R99 HSPA off
Your welcome, Peace out!

THIS IS A GREAT POST (even if it is a repost from whirlpool)!
So many people appear to be having this issue (including myself on O2 UK) where the data connection is stalling.
That code (*#301279#) is a gem.
Whilst I am certainly not happy that Samsung have released this phone with such a massive issue (telling you to wait until KE9 for a fix is really quite terrible!), I would rather have this fix in the meantime whilst waiting for the new firmware.
I have just disabled H/H+ by selecting 'Release 99 HSPA off' and my stalling issues have disappeared. Furthermore, my down speed is still 1.5 Mbps and upload speed is also 1.5 Mbps. I am more than happy with that speed. As the quoted post states, if you want more than this speed, this solution will not be good for you.
Thanks for posting this dusty_nw, this has been bugging me for weeks.

If you have it enabled it will fall from H to 3G in 7 seconds when connection is idle, otherwise in 30 seconds. 7 seconds are to short it will lose time and battery renegotiating to H to often. Ex: when you read your rss feed it will renegtiate higher speed for every article you read, very annoying.

this should be stickied, fixed my issues i had on optus the connection would continually change from H, and 3g and stall i just disabled all except 3g and now its perfect and very quick great post!

Used my finger to press "[2] Change HSPA Revision"
Pressed "[2] Release 5"
Goes to menu with two options of which none seem to do anything when pushed.
Went back to strat of menu and selected "[1] Release R99"
Same options and none can be clicked.
So am I not doing this right? Have the changes been made with no signs or message? If they have changed how do I get them back?
I expected the option to change to visually say its "off" or something.

Although no message came up it appears my phone is staying in 3g so maybe it worked... Although I am in low reception visiting the country side so maybe they don't have H or H+ anyway....
If I selected the first option does this restrict data to 3G?
Select 2nd option for H?
or Select 3rd option for H+ or unrestricted?
Is this how its works?
Edit: I have now found it works like I thought. The screen after I click either of the options then shows what is active and is the confirmation in a way. I jumped on the forum a little too quick......

Hi. I've book marked this because I get this issue thanks.
However it is worth noting that difference between 6 and 5 is only hsupa which is upload. So you wouldn't expect change in download speeds changing that going back to 3g of course affects both directions.

One thing i did on mine with Telstra is change the APN from Telstra.wap to Telstra.internet made the internet feel better. Also got much better upload and download speeds.

Telstra.iph works best for me in Perth.

I use a SGS2 (bought in Europe through Expansys) on Telstra since 2 months now, without any issue. I used several firmwares and kernels since then (not to test, just to update: KE7, KG2, KG3), all behaved the same way.
I tried two different APN (telstra.iph and telstra.wap), both gave me the same kind of speeds (quite good, except some times in the middle of the day).
I never found the datas to create the telstra.internet APN (they do not seem to be on ausdroid). Could someone point me to them?

As an aside, I've just finished testing the I9000TDUKF4 modem (yes it works!), if Telstra did actually have tweaks made as they claim, there was no discernible difference on Telstra's NextG using their 'T' version KF4 modem and a stock KG3.
Any changes if any must be on the hardware level or via software set tweaks, the modem really didn't make any difference at all to my download speeds.
For those wanting to replicate the experiment or muck around I've uploaded the Telstra 'T' variant KF4 modem here: http://www.multiupload.com/VKPFYPURD5

Thanks for this, I just stumbled upon this thread, messed about with a few settings and getting much better use out of NEXT G
Cheers
