The only problems I see with this modem is battery life with I am seeing inconsistencies with. I flashed at 100% with the phone on charge when flashing. I saw 25% loss in the first hour and a half. I then deleted battery stats and continued to loss % quickly till I got to 63% and it seems to be holding and running fairly well.

While I agree that your signal bars may be lying to you, simply ignoring the problem is not a fix. To find out what is really going on you should go into the service mode:
On the dial pad enter *#*#197328640#*#*
select [1] DEBUG SCREEN
select [1] BASIC INFORMATION
Now you'll see real info on your signal and what band your phone is using. The important lines are the third and last. The third tells you what band and if you're using WCDMA or GSM. The RSCP value in the last line is your real signal strength and should be between -50 and -113 with lower numbers being better.
In order to make this thread useful, one should post their kernel/modem/rom information and what kinds of signal they are seeing with various combinations in the same locations. Posting location info might be beneficial as well.
If you want to force your phone to a single, or multiple bands, enter service mode from above then:
[1] DEBUG SCREEN
[8] PHONE CONTROL
[7] NETWORK CONTROL
[2] BAND SELECTION
From there you can select the bands you want the phone to connect to. Just remember that to go backward through the service mode, you have to use the soft keys as the back capacitive key will exit the service mode.
I'll start some useful information:
ROM: Tayutama's 1.0.3
Modem: JPM
Kernel: Reorient 2.1
Location: Indianapolis, IN
Observations:
At home even after enabling the 850 WCDMA band in the service menu while on automatic the phone was still trying to connect to the 1900 WCDMA band with a very poor signal > -109. Eventually it would even give up on the WCDMA signal and fall back to GSM 1900. I could force it to use 850 WDCMA only and see a good signal, but then if I were to leave the 850 WCDMA coverage area I'd have no signal at all. I returned to Cognition 2.1.7 and while I'm at home, the phone uses the 850 WCDMA band and has a good signal -80 to -95
Ok so here is what it says
WCDMA 1900 band 2
RSCP:-96/-103 ( Bounces around)
I have 3 bars here at work. I will report what it is at home were I have no bars once I get home.
Edit: This is running Tayutama's JPM Froyo 1.0.3 w/Xcaliburinhand's Re-oriented Kernel with voodoo 2.1 jpm modem.
correct me if I'm wrong here but isn't WCDMA for data and GSM for voice?
I've been unplugged for 9 hrs 41 min... of normal use (calls, texts, email, wordfeud, light browsing, and a couple of market updates)
I'm at 58%
The weird thing I'm having an issue with, with the JPM modem at least, is when I got to work this morning, my phone would only show it was connect on G, not 3G, just G. Speedtests were in the 40/60kbs range for up and down. I had the 850 band enabled. Flashed back to the JI6 modem, and I connect at H. Speedtests are still low, for the downstream at least, with 500-800 down, 1.7-2MBps up.
The other thing that I'm wondering about is this: I bought a Vibrant off of craigslist because it was hella cheap, and I heard in some areas you could get AT&T 3G with a Vibrant, and was thinking about switching to T-Mo. Anyways, at home, I would get 3-4MB/s download speeds with the unlocked Vibrant & and AT&T SIM. I haven't come close to that with any of my Captivate. At least I'm pretty sure that's what I was getting. I was going to wait to post something about this until I had a chance to test the Vibrant on the AT&T 3G at my house, but then I saw this post about the modem and with the problem I had with data once I got to work, I thought I'd post.
Oh yeah, and I'm currently on Tayutama's 1.03 Captivate ROM/xcaliburinhand's 2.1 w/ Voodoo & BLN.
edit - With JI6, connecting on WCDMA 850, RSCP ≈ -90. If I get a chance, I'll flash back to JPM and test again before I leave, but I doubt I will as I'll have to un-Voodoo before doing that.

WCDMA is for high speed data (3G, NextG, HSDPA/UPA, or UMTS) , and GSM can do both voice and data (Edge, 2G, slow ass, whatever you want to call it)

Go into the service menu and post your connection info. You are partially correct about using a T-Mobile phone on AT&T's network. T-Mobile uses 1700 and 2100 Mhz for its 3G bands while AT&T uses 850 and 1900. That you get any 3g signal at all is kind of surprising. If you use the service menu you should be able to lock the phone to any one of the available bands, then return to the basic information and see your signal strength and such. That should give you some insight as to what is happening. Do you get a good signal with any other rom/modem/kernel combinations?

Uh well, it was pretty widely reported that Vibrants could get on AT&T 3G, but that Captivates couldn't get on T-Mo 3G. I forget why that is atm, I thought it was that they could connect the older 3G towers, whatever frequency that is. But it isn't a fluke, several people have tested it. The Vibrant would get 3G at my house, but not at work, and I didn't want to keep T-Mo anyway, so for now I have to phone, although I'll probably be selling it soon.
Anyways, after flashing back to JPM & enabling the 850 band, I only connect to GSM 1900, RSSI -91.

I think you do. I would
Yes. You always, always, always, always, always, always need to disable Voodoo before flashing anything. JPK seems to be a winner for now. I actually never had any complaints with JI6, and who knows, I may go back to that if I have the same problems I had at work with JPK as I did with JPM.
So, to back to what I had mentioned earlier, I checked my Vibrant when I got home, and I was connecting on WCDMA Band 2 (1900MHz) and getting pretty awesome 3G speeds. I ran speedtest.net three times and averaged 2250kbps down, upstream had two good runs, both around 1300kbps, and one around 300. This was with modem T959UVJI2 and eugene's Froyo ROM.
edit edit - Interesting, I went into the band selection menu on the Vibrant and I could select the 850MHz band. I'm going to look into this a little more.
I have my custom jpm rom with the jpm modem and the 2.1 voodoo.
my phone was unplugged from 7 am till 8 pm with moderate use and was at 75%.
I do use juice defender but jpm has the best battery life I have seen
12 hours off charger @ 24%; moderate to heavy use w/ GPS navigation on way home, checking email throughout the day, texting, and web use.
using:
1.03 Tatuyama ROM w/ JPM Modem
Tatuyama 1.0.3

jpm modem
wcdma 1900 band 2

Battery life is at 25% after approx. 12hrs of work use.
Does the JPK modem enables HSUPA like JPM does?

Has anyone tried this on Nexus One?
http://forum.xda-developers.com/showthread.php?t=670999
"GSM auto (PRL)" works on AT&T Nexus, I don't know if it improves the battery life over "WCDMA preferred"
***EDIT***
Looks like this process works by improving battery life when phone is idle. Here are the instructions from the first original post.
1) Goto dialer and dial *#*#4636#*#* (DO NOT press send)
wait a second and you will get the test menu.
2) In the test menu choose 'Phone Information'
3) scroll down and choose on the first drop down - GSM auto (PRL) (for high speed data) or GSM only (You may get 3g if not use GSM auto (PRL)) Don't know what PRL means, but GSM auto (PRL) allows High speed data HSDPA (it was previously on GSM/CDMA auto(PRL) I think.)
4) Back all the way out.
5) You might want to reboot, but I found the settings worked straight away.
Edit 3 - I don't take any responsibility for step 6 -
6) Try other settings on the dropdown if you are brave as I don't know the consequencies of using settings like "EvDo only" and "unknown" as they may be better depending on the way your provider provides information.
Edit 4 - can't seem to select the other settings like EvDo and unkown anyway.
Edit 3 - TBH - GSM auto (PRL) is working for me with HSDPA and I will try (PRL) instead of GSM auto (PRL) <- edit - previously it mistakenly said GSM only the CDMA and WCDMA settings later to see what other effects there are.

Results for HTC Hero:
Your results will vary depending on the rom, but it should improve battery performance - some have had better results than me using this.
GSM only <---- If you don't get 3g with this it is the same as 2g setting then use GSM auto (PRL) if you want faster than 2g (as some people are getting 3g on GSM only - I will investigate. (if you don't use internet or don't need fast internet)
5½ Hrs - lost 5% Battery - This one is same as running 2g as you don't get HSDPA, but using Opera browser makes browsing fast even using this. If you want Higher speed data use the one below.
GSM auto (PRL) <---- Recommended if you want High speed Internet and save battery
1:40am to 2:00pm (12hrs 20 mins) - lost 40% battery with moderate use a bit of surfing at HSDPA speeds, a few calls and messing with a few apps. Other people have had even better results than me though, so I might change my rom and try again. (I would usually about this amount of time I would have lost about 70-75% - and yes it was that ridiculous - I had to find something to stop this).
" WCDMA Only"
2:06pm to 11:37pm - (9hrs 31mins) lost 46% battery again moderate use and a reboot
This one might be useful if you live in a place that has low GSM signal like the chap in post #10 as it does give HSDPA - but this is only a suggestion as I cannot test it in Iceland. Anyway
" WCDMA preferred"
6:02am to 2:51pm - (8hr 49mins) lost 41% battery this time with less use that the WCDMA use and no reboots.

I'll give it a try
i read the first page, what exactly does "PRL" stand for? and isnt this just using GSM-only? how is it able to use gsm but then switch to HSDPA (3g) for data? i didnt think that was possible.
I have been doing that for a long time and I'm pretty sure it helps...
Just set it to WCDMA only and you are all set...
well I think this really might help. I changed it to gsm auto (PRL) and my phone still uses 3g and my battery only dropped 2% in an hour and 10 min. went from 86 to 84% which it used to drop like 6% in That same time period.
I have to do more testing though to really know for sure.
mine was on WCDMA preferred....will i lose anything by switching to GSM AUTO (PRL)?
Giving this a whirl. When I'm at home and at work I'm on wifi which, combined, is like 90% of the time the phone is running so not sure how much it will affect me, but lets see

you won't lose anything from my testing so far. full 3g still works and my data speeds are over 1.5 Mbps.
my theory is that this stops our phone from constantly searching for a roaming partner/network. if true ATT has no roaming agreements so who cares.

I had that problem too but i wasnt sure if it was just where i was
Just set to GSM AUTO (PRL) and reboot.
I downloaded two apps from the market and both downloaded faster than usual. Also the browser seems to load faster.
I'll report back with battery data.
It may be that this saves battery by using the PRL acquisition and system tables for allowed frequency + system lists, thus stopping the phone from searching all the time.
I've not had it on this setting very long so I can't really tell yet, but it looks encouraging so far...
i still am testing, but i have definitely noticed a MAJOR improvement so far. for example this morning my phoen has been off the charger for 4 hours, and i'm still above 90%. on normal days, my phone would have dropped much more than this.
and the battery voltage seems to be staying constant too. for example my batter was at 4040 mV, and i checked an hour later, and it was still at 4040 mV. this NEVER happened before, it would always drop some amount.
is it possible that this entire time our phones have been actively searching and updating the roaming list, but with this setting now its just locked on the home network and not searching anymore?

I can confirm that. My phone seems to use much less power while in standby mode and it just dropped from 99% to 89% in 7 hrs, with auto synching of Gmail, Facebook and other stuff, while in the last days I could experience drops of 10% in about 1.5/2 hrs. I'll keep testing this mode and will post back if I'll have something interesting to share

i used to kill 10% in an hour EASILY, sometimes more if i used the phone hear and there. but now with this setting, i'm now at 7.5 hours, and way more than half battery left still. on normal days my battery would be dead in 6 hours sometimes. huge improvement.

Well, that's because you aren't on a CDMA carrier then. I checked and the Nexus One only comes in GSM. If this is a Nexus One you have, then you are have a GSM version, and are on a GSM carrier.
Um, surprise!
Ok, first off my Vibrant has flat out awful reception.. fluctuates randomly between 4 bars and 0 bars on 3g and sometimes cant get more than 1 bar 3g in the middle of an HSPA+ city(Memphis). Its not a bar display problem, sometimes my speedtest shows download speeds as low as 150kbps. If that wasnt bad enough it takes forever to switch between 3g and edge, by forever I mean sometimes a full 60 seconds+ and if Im running a data using program (Pandora for instance) it sometimes refuses to switch at all... Is this a known issue or is it just my phone?? I know my G1 did not have these issues.
Try doing a master reset on your device.
If the master reset dosen't work, you might reflash the full stock rom from the android dev section. There's alot of people that have been reporting substantial increases in their reception and connection speeds.
And if you think it takes a long time to switch b/t 3g and edge, you ought to try owning an evo for a month. It takes FOREVA to switch the 4g radio on and off, at least 3 min for me, takes about that long to turn it on after a reset too.
Just because you're in a HSPA+ city doesn't mean you're on the HSPA+ network.
If you're having problems with it aquiring the 3G network try a new sim.
The G1 has mediocre reception but it is aided by the fact that the antenna is at the top and not the bottom like all other phones.
Bump,
I am actually having this problem too, I have tried a factory reset, I also tried reflashing the T-Mobile stock fimware, but it has not helped. I have good 3g and edge reception where I live.
Oh yeah, I am using ATT on the vibrant.
When this happens (ie. not switching between network or slow switch time), you can trigger airplane mode and then undo it and the phone will pick up the right network or switch network faster. For example, if use 2g network is checked, it will enter Edge, etc.
I see exactly what you guys are talking about, locking it on 3G will fix this right up. I was driving down the freeway and I KNOW I was passing 3G towers, but the Vibrant stayed on EDGE for way too long. I locked it on 3G and I never lost the signal and it was 4 bars for nearly all of the trip so I know 3G was there, it just wasn't switching back fast enough.
Looking under the Samsung debug mode, the Vibrant will hold onto 3G until -115 Recieve power, which is basically -115dBm under the Android network menu. Of course over -101 RSCP, it will show 0 bars so it's hard to know when reception is acutally really bad.
It should show -0 bars at -113dBm, 1 bar until -101dBm, 2 bars until -89dBm, 3 bars until -79dBm, and 4 bars until -51dBm.
just disable the extra frequencies from service menu and it will be super quick.
I'll try that, at any rate it should be remedied by Samsung.

That's an unintuitive user interface. sheesh.
Looking at Wikipedia, it looks like TMO uses 1700/2100 WCDMA and 850/1900 GSM (2G/EDGE). There's also a WCDMA 1900, but according to what I'm reading, TMO doesn't use WCDMA signaling on 1900, just GSM/EDGE.
To try it, go to the service menu using the steps for 3G locking and select 1700 only instead of WCDMA ALL. Then go back using menu/back (not the back button) twice and go to Combi Bands and select WCDMA 2100. That should enable just 1700/2100 WCDMA 3G service. Turning on PCS 1900 does seem to get me an EDGE connection. Enabling GSM 850 ONLY gives me emergency calls only, so it might be worth keeping on for 911 calls. 850 goes further so it might have service when the others don't.
I don't get 3G service in my basement, for example, so I would like to keep EDGE enabled. Hopefully enabling just the bands that I would use will help keep the search times down.

To really get a full re-flash, you need Odin right now. It should be possible to do it without Odin now, but I don't know if anyone has put together a stock ROM that way yet.
I didn't see any difference in speed/stability with the stock Odin flash, but others might have. It seems to depend on the network more than the local stuff.
Band IV 1700 includes 2100Mhz so you don't have to enable it. From what I can tell, no.. combi-bands doesn't do much for the slow 3G requisition. I'm just going to lock it on 3G when I'm not at home.

This didn't work for me. I would do this, and it would only work changing from 3G to EDGE. But, from when I would put it on use 3g, it would first change from airplane mode to EDGE, then take around 1 min to change to 3G.

How do I disable the frequencies? I can only seem to enable them.
I have a weird problem.
3g works fine for my captivate excpt when I am in the center of my small town 1 cell tower. the tower is a 1900 mhz gsm and 3g no 850 at all.
My phone drops to gprs not even edge when connecting to that tower.
I have tried many modems and tried swapping some settings in the debug menu.
any ideas
EDIT MODS I AM SORRY. AFTER I POSTED THIS THRED I REALIZED I PUT IT IN THE WRONG FORUM.
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

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

****************** 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

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.

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.

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
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:

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
Sent from my GT-I9100 using XDA Premium App
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.
