KNOW THIS IS LONG BUT IT IS INTERESTING! JUST GET THROUGH IT!
ON 6 July 2007 I posted:
[I was driving home from work on Vanowen St from North Hollywood, an area which has had 3G coverage for quite a while, while watching some free MobiTV in the LA traffic. My eyes widened with excitement when the phone (running BLACK MAGIC LE) showed full HSDPA reception as a crossed Lindley Ave, then Reseda, then Tampa, and all the way to my place on Winnetka where the HSDPA was still on but at 2-3 bars of reception. HOWEVER, to my great dismay, as soon as I ended the data call, the same ol' "E" was right back up there... forcing WCDMA + going back to where I was apparently getting full 3G reception failed to pick up UMTS... Now, given what little knowledge I have + some educated guessing, I suspect one of the following scenarios as being the culprit of this disgusting event:
A. There could have simply been a glitch in the phone, where it showed the H and 3G symbols instead of the E; HOWEVER, the streaming video on MobiTV was significantly better than anything i've seen on EDGE. Maybe some caching may be responsible for this?
B. Newly activated UMTS towers were able to register my phone when it attempted to continue an existing HSDPA data call, but have yet to be instructed to register idle phones looking for signals.]
Today, after repeating the same process while using speed tests to verify HSDPA speeds, I contacted AT&T and again, luckily, got to someone who knew his sht. He went ahead and listed some UMTS tower locations in my area and along my route home from work (Vanowen St) but stated that the towers were set for PUBLIC activation on 2 August 2007. So theres it is, the official launch date for 3G accross the whole SFV is 8/2/07. NOW, as for me being able to connect to these "unactivated towers": the tech agreed with my theory that while the towers fail to register my phone from a reset and kick it off upon data disconnection, they ARE OBVIOUSLY ACTIVE because I am able to connect to them, but only when entering their range while on an ACTIVE HSDPA connection. So here are my questions for the COOKS/MODS/PROS:
1. Are you aware of what method these towers may be using to screen phones for "testing purposes" (IMEI maybe?)?
2. Is there any way to trick the tower into registering my phone without having to drive to an "active" 3G zone and back?
ANY FEEDBACK WILL REALLY BE APPRECIATED!!!
Thanks very much for the ifo. I have no idea how you connected to HSDPA before it was actually released? Was it that much faster than UMTS?
Hi,
after having several missed calls going straight to my answering machine on my new HTC Hero. I was getting a bit paranoiac, so I've decided to test in/out calls.
Basically, 90 of my incoming calls were going straight to my answering machine. Out-call were about 30% KO
After several tests, to make sure there was a problem, I've decided to request for support from HTC.
Support told me that I should shut the 3g connection every time I would want to receive a call .
So I tried and Bingo, if 3G is activated, I get 10% of the calls, if I deactivate it 90% success.
So you'll say, I should be happy? Right? Wrong!
The main use of that kind of phone is to have a data integration, otherwise I would have kept my old nokia from 10 years ago..
Here basically, if I follow HTC idea, I should keep the 3g closed, sometime, I should switch it on to get my mails, thanks to the non true push capacities (ok this one is not htc) then wait for the sync, maybe force it , get my mails, and then, shut 3g back and pray that no Über important call would have been done.
Well that plain sucks!
Never had such a thing on my previous Data friendly mobiles, why should I accept it on the Hero?
If someone have come across this bug, cause it is a bug, how did he/she managed to fix it?
Thanks
works fine on mine....i suggest you are on a ****e network, or on only 2G where you are. that's what usually causes this.
I guess they suggested this because it sounds like your network hasn't figured out how to route calls properly on their network when data is active, and they dump it straight to voicemail when there is a data connection active.
not the phone's fault, the phone won't even know that the call has been missed, the network simply does not route the call through and sends it to voicemail instead.
i had this on O2 a while ago. went to t-mobile (who knew how to set up their network properly for data) and never had this issue since when i am on 3G coverage. if i'm on 2G signal and have active data then yes, i miss calls. but that's how 2G networks operate.
it's truly shocking how many networks out there have absolutely no idea how to set up their networks properly for data!
Well I wish it would be that, my signal goes from -63 dbm 25 asu(80% of the time) to -81 dbm 16 asu.
Just after my post, I called one of my friend working in carrier terminal validation.
What he told me was, 2 options:
- Same bug was on the htc cruise, bug got corrected after a fw update.
- Some of my carrier radio are buggy and 3g goes over gsm.(SFR/VOdaphone France)
I bet for the first option since I had the problem in various places since I didn't want to ask support for nothing and get busted for a " feeling and not facts" (did the test in 3 differend location 80 tests in total(I used to be a tester....).
I will update the topic if I get news about it

You shouldn't accept it - but most people don't have this issue!
It's unlikely to be a "bug" per se, because otherwise it would be endemic behaviour, so it's either:
1. Your physical device (get it changed!)
2. Your network.
In addition, just an FYI in case you've got the new Sprint Hero, but most CDMA networks (including Sprint) do not support simultaneous voice and data. I've no idea what happens in practice on Sprint, but I'd imagine if you were actively using data your voice calls would get diverted to voicemail unless Sprint automatically suspends data when a voice call is pending.

Dave
You're on SFR?
OUCH!!!!
Sounds like you have a nice strong signal, but is it 2G or 3G? (do you see a G, E 3G or H at the top of the screen?
if you see G or E, it's cos you're on 2G, If you get 3G or H, it's on 3G.
And yes, there were a few issues with the P3300 and the cruise, but they were mainly on Bouygues, not so much on SFR.
There's nothing known of on the hero, and as SFR sell the Magic, i would have thought they would have ironed out any issues already...
Hi,
I'm mostly in HSDPA or 3G.
I still have contacts with people at SFR (used to work there till recently) they might share a bit of info.
Idk if yours is CDMA or the GSM one but on mine (CDMA) under the mobile network settings, I have the option to switch the mode of operation to ether Hybrid, EVDO only, and 1X only. Now, I know how Sprint's network works, not sure if it's the same for any other networks but if I set it to Evdo only (3g) I'll miss all my calls because Sprint does voice over 1X. Hybrid mode does EVDO when you're using data and switches to 1X when you're doing voice/sms.

Regarding this and your suggestion that 2g and data will result in missed calls, Can you suggest how to avoid this happening? I live and work in the country and only have 2g, so have found quite often people have mentioned my phone not even ringing- straight to answer phone. This explains it.
Nice to know, but annoying if I can't solve it- I run a business and my phone is very important.
Cheers,

Hi, I'm on hybrid
that is what i hate about hero, it is really great except for the fact that it switches from 2g to 3g without notice. i want it to be permanently stuck in 3g for faster downloads and mms, but when it uses 2g, i cant send and receive mms and surfing the web is slow as heck! im still looking for an app that would permanently put the device in 3g just like with winmo it which you can use wcdma ONLY.
cheers!
If you use AnyCut, you can create a short cut by selecting:
New Shortcut->Activity->Phone info
This will create a shortcut on your homescreen which beings up a hidden "engineering" screen on which you'll find an drop down for "Set preferred network type" where you can select WCDMA only.
Regards,
Dave
alternatively, open the phone app
dial *#*#4636#*#* and select phone info
scroll down and set it to WCDMA only.
does the same thing but saves installing an app.

That is not specific to the Hero. The fact is, every carrier's 2G network has better coverage than their 3G network. When the phone cannot detect strong enough 3G signal, it jumps back to 2G network. The idea is that slow data transmission is better than no data transmission at all. Many smartphones have the option to lock the mobile network to 2G only. One advantage is that it gets better reception, and another advantage is longer battery life (the 3G chip eats battery much faster than 2G).
If you instead lock the phone to its 3G network. The first thing you will notice is that battery life is significantly shorter. And chance is that you may be getting very spotty reception, because you are not allowing to phone to switch to 2G when it gets no 3G signal. When there is no 3G signal, forcing the phone to "3G only" mode won't give you faster download, it gives you no download.

true true. i usually charge my phone everynight though. problem that i have with 2g is that i cant send and recieve mms and yeah data connection is slow. in our place 3g signal is ok. i also lock my topaz for wcdma only. but it is ok that it switches to 2g in low signal areas.
Thanks!
You actually use mms?
Wow, they do exist.

What NOM1 Networks are there in the UK? I only get 2g in my area (booo) and could do with an operator that works right. T-Mobile forums suggest they still have an issue
Hi
I've checked it with Hero running in PlusGSM in Poland.
Regardless if I select 2G/3G or even "WCDMA preffered/GSM Only/WCDMA only" setting the phone is not available for incoming voice calls during data transfer. Every time when I start internet connection (example: SSH session) I'm not available for incoming calls. At this site I do have both strong 2G and strong 3G networks.
I would like to mention that a few days ago I've swapped Samsung SGH-i600 (WinMo 6.0) for HTC Hero - so I'm using the same SIM card in the same network and the same place. SHG-I600 was able to perform both data transfer (on 2G) and voice (on 3G) on the same time. HTC Hero is not...
I wonder if this is 'feature by design' or a bug in software?
Have had this phone a coupla months, happy with it except the stupid GPS problem and some other connection problem.
When using wifi connection at home, if i stop browsing and close the screen for a few minutes and go back to surf internet, the wifi will stop working, turning wifi off and on again will make it work. Not too difficult but sometimes this feels sucks.
second problem is, occationally i will lose the "3G" or "H" sign on the top and cannot connect to internet using 3G data connection. i have no idea why this is happening. sometimes when i am out on street, try to check some information online, 3g is my only option and it really bothers me when it stops working. i'm using orange. all setting are as original.
Anyone knows how to solve these 2 problems?
the phone either works on
850/1900/2100
or
900/1900/2100
so depending on the model that you purchased
and where you live
also the cell phone provider that you are using
you might not get the full band usage of your phone
for example using the above models on a phone service that only uses
1700/1900/2100
then you are cripled
some telcos only use 1 band or 2 bands at most
1700 or 2100 for example

3g nodes and 2g bts wont give you the same area coverage, yes you will lose the H and drop down to 3g if your -db rating (signal is low) is at the highest limit for the cell and it deems you either need handing off to another site or you were one of the last ones to be allocated a slot and get kicked.
its how the cookie crumbles, no where will give you 100% coverage and if u are close to a small site thats overloaded with traffic you will always get crappy uplink and downlink...
b
I dont know where you are or what provider you use, but I have the same problem with my I900M on bell. it is apparently a widely known issue with Bell, and they associated my phone with the ongoing ticket incase it gets resolved they'll contact me.
Also, when I lose the 3g, ts a good chance my phone is going to lock up and need a battery pull to boot back up.
So Basically if I leave the house or wifi spot, I try not to show people my internet on my phone so it doesnt look like I'm carrying a brick in my pocket everywhere.

so that's something to do with the carrier? Thanks for the explanation!
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!
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.
Sent from my GT-I9100 using XDA Premium App
May be a sillt question but.
I used the stock dialer and put *#301279# in
Menu popped up.
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.

WOW!!!! I just switched over.. mine use to max out at about 8Mbps, but my last test before the swap was 6.7Mbps... switched over and i tested 10Mbps and then 11mpbs!!

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

I've been following the mobile data connectivity issue that some users are experiencing (where data connection drops randomly, apparently coinciding with a lot of switching between 3G/H/H+).
Initially, people suggested disabling 'fast dormancy' using *#*#9900#*#*, however, this did not work for many, including myself.
In this post http://forum.xda-developers.com/showpost.php?p=15250511&postcount=6, there appears to be a solution, albeit a workaround.
I have started this thread, as there are so many separate threads about this issue, and only the Telstra Australia thread had this answer (as far as I've read). I have copied the post (a repost from whirlpool) by dusty_nz below. Basically, the problem is serious, the guys from Samsung have insisted this will be fixed in KE9, but there is a workaround in the mean time (disabling H+ and H, or just disabling H+ using *#301279#). This may seem drastic to speed freaks, but 3G connection alone should still give you 1.5 Mb up/down if you can put up with that. This has worked for me, no more data stalling, no more server errors etc. etc. I hope H/H+ will be fixed in future firmware.
Here is the post:

****************** 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 works! thanks!
Cheers!
Just tried this and I got 1800kbps on 3g!!
Hmm, i played around with those codes. If i choose to drop H+ and H, stays on 3G, but speed is crappy for me. So i want to drop only H+, but when i do that phone stays only on 3G too, not attempting to connect to H. Am i doing something wrong ?

*#301279#
Option [1] Release R99(HSPA OFF) - This should turn H+ and H off
Option [2] Release 5(HSDPA ONLY) - This should turn just H+ off (what you want)
Option [3] Release 6(HSDPA/HSUPA) - This should turn H+ and H on
To test this, you might want to make sure you are in an area that can pick up 3G, H and H+.
One week on since I selected Option [1] and I have not had any data stalling issues, before I was having data dropping every few minutes whilst browsing.
I tried Option [2] and still had the stalling issue.
Good luck.

I hardly ever get H+, which is why i want to turn it off, thing is if i choose option 2, i only get 3G, while with option 3 i get 3G and H (probably H+ too if i were in the right place). Option 1 works fine, doesn't seem to stall, but 3G speed is crap in my network, that's why i wanted option 2.
Tried all three settings and I am getting about the same speeds with all three settings, 3600-4200 down and 1550-1620 up. So will try setting 1 to see if my connection carries on dropping out.
Thanks
Wat is the code for miui

I actually tried this before on a few different radios and it didn't really work. The real problem I have is when I get in an elevator for a minute and get out shortly. It's not long enough in the elevator for the phone to say "No Signal" but it's still long enough for the data connection to hang and never bother hooking back up when I get off the elevator.
I'll try again though... will report back.
same here .... i tried the three options but problem persist
I have tried the codes above, including disabling dormancy but my internet still will not connect to the internet. Please help.
I'm with Optus (TPG) and I never really see H. It's either 3G, or H+.
I tried disabling H+ (option 2), and like the other guy now I only see 3G.
My Speedtest with only 3G was:
Down - 228.2kB/s
With H+ enabled (option 3), my Speedtest was:
Down - 482kB/s (but it's been as high as 1103.9kB/s in previous tests.
For now I'll just keep it as it is and put up with the occasional freezes. Hopefully it's fixed soon in a firmware release.
i cant seem to get the codes working.. after i dial *#301279# nothing happens, no menu nothing. tried on my wife's galaxy s 2 same thing.. is there an app to disable HSDPA?
\\Issue solved
Is this issue mainly due to the carrier?
I did not have this problem b4. Now I found that my phone might suffer from this.
Tried to disable the H+ or H & H+ at the same time, it seems the issue is still there.
I am on Vodafone Australia network. And I just raised this similar topic on Whirlpool, if you guys would like to discuss this network problem on an OZ forum, plz refer to the below

For me it's still the same, coming from KF2 to KG2. Will try KG3.
Any one with new modem firmware that 100% fixed the 3G drop/stuck connection(only see upload sign lit) bug? I am running KG1 modem(stock rom no root) and still experiencing this issue on ATT in Bloomington, Indiana USA.
I also realized S2 uses Infineon modem chip which is the same supplier for the iPhone3G that had the 3G slow down, drop call issue..
Could this issue be the chip at the end?? Why would Samsung taking forever to fix this critical flaw on I9100??
I'm on 3 UK. Had the cutout on KG1 and KG2. But it's definitely gone away in KG3.
I'm on Airtel India on KG3 and I still have the data stalling issue.
Seems to me like this issue surfaces more when I'm at home on wifi and then step out to data.
Trying out these service codes now to see if it helps to turn off high speed data.
It would make sense for Samsung to include these settings in the rom itself even for those without issues but want to save battery.
