There is not much you can change out of the box to optimize performance. If you have the Tilt from AT&T then you are really screwed, since that ROM has so much bloat ware on it.
If you have the tilt you can do a hard reset, followed by a soft reset when it starts configure AT&T's bloat ware. This will give you the stripped down version of the ROM and you will still have AT&T's network settings. If that's not enough you can install Hard SPL and then flash any ROM you want. There are some stripped down just to the barebones. Finally, you can install the KaiserTweak which will let you choose how the Kaiser takes advantage of the RAM for the different caches.

I have the Kaiser.
I have 3G in my town but I am not impressed with the speed.
I thought maybe a few settings tweaks could improve it...

Are you talking about Download Speed or Performance Speed??
not sure if you are trying to improve network connection speeds or the device performance speeds? 3G only affects your internet connection speeds and has nothing to do with how quickly your device operates.
If you are not getting browsing speeds of at least over 300/kbs you might not have a 3G sim card. In that case you need to contact your carrier and request a 3G - 64K sim card.
Here is a link where you can test your connection speed. Make sure you see the 3G icon and you have a good signal.

I have the old Cingular Orange SIM Card. It says 64K smartchip in the front and 3G in the back.
Do you think this may be the cause of my slow speeds?

I am wondering the same thing. Does anyone know if there is a difference b/w the cingular 3G SIM vs the AT&T 3G SIM?

I have got my TyTn II two days back.
There seems to be some problem with Internet Speed whether it is on PIE or Opera 8.65 or Opera Mini. The problem is this:
1) On my HTC Touch I could get speeds of 250 Kilobits / second on my Edge connection. (There is no 3G in my country)
2) Now I have placed the SIM from the Touch to the TyTn II and my speeds have been almost halved. I cannot get more than 100 - 120 Kilobits / Second.
3) The Internet connection on both devices is configured exactly the same. I have tried numerous times but when the SIM is in the Touch I get 250 kbs but when the same SIM is in the TyTn II I get 100 Kilobits per second.
4) I use "Hudsonmobile Ipdashboard" to measure speeds in real time and this program gives a graph of the upload / download / total speeds.
Can somebody please help as this excellent device is being marred slow Internet connections.
Has anyone else noticed this.
Thanks

Touch cruise won´t connect to HSDPA Tmobile NL

My TC won´t connect to the T mobile HSDPA NL network. It currently is showing 3G with full signal strength. I also have HSDPA coverage in my area.
I talked to Tmobile customer service and they say its probably a setting in th e phone. I have HSDPA enabled in the phone. I have had my sim card replaced since my old one was about 8 years old.
Any ideas?
Is there anyone on the Tmobile network that has HSDPA running on the TC?
Thanks.

I had the same problem... but the Polaris told me only GPRS network was available... After a Hard Reset the problem went away...
If you've been messing whith aGPS, that could be the source of your problem as, that's the only regedit I didn't do after the Hard Reset...

Hi,
For the poster of this thread. Check this link. It's in dutch, maybe things get clearer.

I already did a hard reset and I haven´t been messing around with the GPS registry settings.
This is really annoying me.

Maverick,
If your Polaris is showing 3G next to the connection that it is sensing the HSDPA. The only time the 3G changes to an H is during packet download. It will switch back and show 3G as a 'ready' state for high speed, 'E' for Edge Ready and 'G' for GPRS ready. The 'E' and 'G' show the same as connected. The '3G' is the only one that changes to 'H' during an active HSDPA transaction.

Exactly the same problem over here.
Pit in combination with my tmobile contract. but no hsdpa

Raskell,
I talked to TMobile customer support about this and they said I should be able to join the HSDPA network the believe the phone is stuck in UMTS mode(3G) they said it's probably a phone setting since I comply to all the requirements for HSDPA. However they couldn't tell me what setting could possibly be wrong.
How do I get it to packet download? should I try to download a large file 50 MB or something like that?

Already did that, stays solid on 3G

You should download a large file when te 3G sign is there. It should become an H when the dowload runs.
With PIT and PIT + it makes no sence to have HSDPA because you never can reach the speed you want.
Only with IT and IT+ it makes sence because then you can reach max speed.

hi Jazzamataz, I´m now downloading a 50 MB file or does it needs larger like 700 MB? However I get a nice 45 KB/s download but no H remains on 3 G.

No 50MB is enough, as soon as data is downloaded it should jump in H mode.
Did you set the mode on auto in the setting of your phone?

The band settings are on auto, I already tried setting them to different bands manually, no effect though. Perhaps the fault lies in TMobiles own network(settings).

As i said on another forum. I have the normal PIT, but when i am on HSDPA i download with around 600kbit/sec. And this is everyday, not just a moment..i really dont understand, but to be honest, i dont care.

Where are you located in NL, did you change any settings on your phone that could be related to HSDPA?

Maverick,
TMobile here in the states does not even support HSDPA. With AT&T(Cingular) they us the 850 MHz band for HSDPA and 1900 for Edge/GPRS. TMo is 1900 only. In Europe, UMTS is 2100 MHz which is not used in the USA.
I know of no phone settings to address this. I agree with the comments to use a bandwidth test site to check your 3G speeds. It may be that you are getting HSDPA. I use http://utilities.globequest.com.ph/ and run the bandwidth meter test several times to ge an average. Mine is typically in the 600-800Kbps range. If I turn off HSDPA, I generally see it drop to 150-200 Kbps. Hope this helps.

Nope, i live in Nijmegen...and i didnt change a thing.

I'll contact TMobile thru mail. Perhaps I get to speak someone at TMobile who's proficient.
Yzord if you didn't change anything in the settings it must be a issue with the TMobile network itself. I live in Almere and according to TMobile there should be HSDPA coverage here.

[Q] Enabling HSUPA on i9020a, ATT

I'm at a loss. I just got a new Nexus S i9020A for ATT, and have discovered that it is not HSUPA enabled. It is consistently 1.8 - 3.0Mbps down (normal for my area) and a MAX of 280 - 300kbps UP.
I've tried adding the ro.ril statements to build.prop as suggested in other Nexus S threads, rebooted 2 times and one more just for good measure, and HSUPA is still not flying.
Also the latency is notably higher than my Atrix was, and my friends rooted captivate w/ custom radio + hsupa.
Any info would be great.
Phone info:
Nexus S I9020A
Rom: Stock, GTJ61 2.3.4
Baseband: I9020AUCKE1
Kernel Version: 2.6.35.7-ge382d80

ok I hate when I post then find something, but its not DIRECTLY pointing to enabling HSUPA, so I figured I'd post here.. if any one has a thread I missed that is directly addressing HSUPA on the i9020A for ATT, please feel free to chime in and shut me up.
I've got HSUPA enabled.. Heres what I did..
I assumed that any ATT baseband would be crippled as the captivate is.. So I tried something.
http://forum.xda-developers.com/showthread.php?t=1116884
I downloaded and flashed: I9020XXKD1 baseband..
So far, its working great. the 850 bands SEEM to be enabled, although the tower I am currently on i don't know its scrambling codes / site id for primary (850mhz) and secondary (1900mhz) carriers thats visible in 4636...
I'm waiting on my Micro Cell to fire up and if it connects, 850 is operating.
Will post results..
Side note: build.prop edits are still present from other threads, including hsxpa=3 amount others.

What did you ever find out? I am considering leaving my Atrix for a i9020a and am a bit concerned with slow NS data...

Do custom ROMs allow for 42mbps?

Do custom ROMs limit the HSPA speed of our phone? Is there some network check where if you're not running on T-Mobile's ROM, you won't be able to access the full speed HSPA+ 42mbps network?

rom won't affect that
have seen a lot of posts with folks getting plus 20mb in the 42mb areas--wish I lived in one--

Do you think the buil.prop settings have anything to do with it?
I remember getting 15mbps a few months back from my home, now the fastest I can get is around 5 :/

sounds like something changed, what do you get in other areas compared to before
some roms don't do as well as others with some folks. but, I never had a rom make that kind of difference.
don't know about buildprop--I doubt it
try the last rom you were on with good speeds. also, maybe the latest radio

I haven't been able to get high speeds like that anywhere really.
What I've noticed is that since switching from the stock ROM, my indicator switches frequently from "H" to "3G". It'll switch back and fourth every 5-10 seconds when I'm using data. This happens with CM9 and CM10 and the modified Sense ROM that I'm running now. I live in an area with excellent 4G coverage and I don't understand why this switching is occurring now when it wasn't back on the stock ROM (and I know the stock ROM had separate indicators for 4G/H and 3G). It doesn't make any sense to me.

the switching is common for a lot of people and is addressed on several threads
if your hboot is under .13 you can flash a newer radio
gotta call it a nite

I don't know if the following setting remains after rooting and installing a custom ROM but check it out and test the different settings:
Settings>Mobile network>Network mode>WCDMA only versus GSM/WCDMA auto

Are you in an HSPA+42 area? T-Mobile only has that in a few markets..

I like my phone switching to edge when HSPA signal is weak because then I still get service and it doesn't kill my battery life. I don't think this would matter because 3G and 4G are on the same bands :/ Which is why I don't understand why it switches....

I am in the Salt Lake City area, which does have HSPA+42
I'll see what I can do with radio flashing. If I get something to work I'll post a guide on it.

I did some tweaks on my phone and saw positive results, I posted a guide for others here.

[Q]build.prop radio related settings

Everything started when I've made some tests and I've noticed some strange things:
- on every KK ROM I've tested, mobile data drops completely after some talk time. It is happening only during calls (long calls usually). It is regardless of the radio used, I have tested it with 1.13, 1.15 and 1.20...the same with all. It is also happening regardless of the call type: on BT (car-kit or headset), speaker, headset, handset. EDIT: Now I made some tests and seems like I don't have this issue anymore but instead I have the issue below. I don't know why and when this started to happen
- as soon as I make a call, the mobile data icon switches from H/H+ to 3G. As soon as the call ends, it switches back to H/H+. I've run some speed tests and it's not only the icon, it's the speed too. I get about 0.09 Mbps during a call with the 3G icon and up to 8 Mbps when not in a call with the H/H+ icon.
Now there are some build.prop entries I don't understand and I couldn't find any explanation on them. There are many threads in which some of them are recommended, some say they work, some say they don't, I am really puzzled. Below there are a few about I couldn't find any details:
- ro.ril.radio.svn = usually value here is 19 but I heard about 01, 02, 03 or 04 as well. Nobody seem to know why it's one or another and more important what does this does.
- ro.ril.hsxpa = usualy 2 but I saw many people recommending 3 or 4 without any arguments on that. What does 3 or 4 do here? Don't say it's enabling HSDPA or HSUPA because the lower values already do that: 0 = UMTS, 1 = HSDPA, 2= HSDPA/HSUPA. So why 3 or 4?
- ro.telephony.ril.v3 = now this is a nice one. Mostly I've seen this set as skipradiooff but I found more: icccardstatus, skipbrokendataca ll ,datacall, signalstrength, facilitylock. What's this all about? What any of these options do?
Now why I ask such stupid questions you'll say. If they work who cares...ok, but DO they work? Has anyone tested if they change something? If yes maybe those persons could bring some light here because nobody seems to know. And I mean if one of the above do change something, the ones that tested and recommend these settings should at least tell us what happens if one or another option is included.
Has anyone commented out for example the ro.ril.radio.svn and see what's happening? Or put 01 or 04 instead of 19 and see if any change? Cause I couldn't find any difference with this option set or not. Why is then recommended? Maybe it's particular to some carriers (I saw alot of settings related to US T-Mobile). If it's true, maybe it's good to know that only for that carrier it does something and on any European carrier it has no effect (or it has, I don't know)
Please anyone who knows some info or made some tests post here. Maybe we could shred some light into this cause after searching and searching I couldn't find anything clear. Everybody is mentioning those with one or another setting but nobody explain.
EDIT: I've start testing
ro.telephony.ril.v3 =icccardstatus - this seem to show a "no SIM" or "insert SIM" icon instead of the cell signal icon. Even so, calls CAN be made, I've tested a few. Probably this disables the ability to read SIM card status so that's why it shows that no SIM is present
ro.telephony.ril.v3 =datacall - this disables completely the mobile data. Icon for mobile data is gone and there's no mobile data access. Browser and any apps are reporting "no connection"
ro.ril.hsxpa = I hope it is not my imagination, maybe others can test as well but here's what I found. If 4 is there, most of the times I get H indicator and speed. If 2 is there, I mostly get H+ indicator and speed. So strange but at least in my case 2 seems to be better than 4 (which anyway I don't know what means). EDIT: Ok, after further testing and searching it seems that value of 3 means HSDPA "uncapped" and 4 means HSUPA "uncapped". So it could be that 4 is better than 2 or 3 but this has to be tested for each particular carrier to see if it's really improving something or not
ro.telephony.ril.v3 =skypbrokendataca ll was the fix (100% of the time) for a data acquisition issue on the HTC Sensation for TMOUS customers. Ironically, it causes a lot of 3g connection problems for non-TMOUS customers though. The problem it fixed was a blinking H or E with corresponding lack of data. Many times, sending a MMS would fix the issue as well, but not always. (thank you @nicknc for clarifications)

Thank you, I'll add this info in OP. Also that should have no impact on Ville in this case
I've also read alot about that H/H+ switch to 3G during calls. Unfortunately I cannot test myself because I don't have 2 phones but I'll keep searching. As I read, it seems there's a similar issue with those having LTE networks (or 4G how it's called). It is known that the LTE network is not capable of having voice but only data. The only way of having voice in a LTE network is via voice-over-IP that is not implemented. That it is called VoLTE (Voice Over IP over LTE) and the project for introducing it has already started but it'll take some time till it'll be finalized. Therefore, if someone is on LTE network will notice that during voice calls the mobile data switches/drops to 3G and resumes on LTE as soon as the call ends (or not...for some carriers it has to be manually switched back). This is implemented by the carrier and it's called CSFB (Circuit Switched Fall Back). The internet is full with complaints and questions related to this data drop, especially in US but it is also in Europe or other zones in which LTE was implemented. Lot of people asks how can they prevent this to happen...short answer is they can't, only way is to change the data plan back to 3G from LTE. More details can be found by searching on Google and also I found this technical article HERE (for those interested in such details)
Now what I believe (but I can't prove or test), is that for the same reason I have that switch from H/H+ to 3G. Vodafone RO has LTE implemented and it could be that when someone makes a voice call, mobile data is automatically dropped to 3G even if it is not on an LTE data plan. When I tested with someone else on the same carrier, he didn't have that dropped data but also he was not living in an area with LTE coverage so it could be that this is happening only where LTE is implemented (that's why I need more time to test and find persons who can help me).

Okay-- a few updates for TMOUS
I tried ro.ril.hsxpa set to 2 for a few days. No appreciable difference, other than an appearance of a tendency to hold onto 2G longer than the phone should in a high-coverage 4G environment.
I also tried hsdpa set to 24 and hsupa set to 6, as everyone likes to whine about how our phone doesn't support values of "28" and "7".
This is where it gets interesting. Regardless of the setting of ro.ril.hsxpa to "2" or "4", I do not get H+ indicator with hsdpa set to 24 and hsupa set to 6. When I flip it back to 28 and 7, I get the H+ indication. There is no appreciable difference in speed, but then again, I am currently getting a speed lower than what I get when at home (10 mbps vs. 14 mbps). So, it could be 10 mbps is the max available on the tower to which I am currently connected.
The upload seems to be lower than normal (2mbps), so it is likely that conditions are not ideal.
When I return home in a few days, it will be interesting to see if there is a difference there between 28 and 24.
It does appear some of these settings might have infiltrated from other HSDPA+42 or even LTE phones, and wouldn't necessarily apply to ours.

The 24 for hsdpa and 6 for hsupa is from the table I found and tells the maximum speed at which device can download or upload. It is useless theoretically to set higher values since the device is not hardware capable of achieving them

I've used those values for many months, along with

ro.telephony.ril.v3=skipradiooff
and I always get the H+, though my data rates have really gone to hell in the last few months...5Mb is good for me these days.

Ok, and what does that "skipradiooff" do? Because nobody seems to know. All are putting that setting in build.prop or recommend it but nobody could tell why. To be honest I didn't notice any difference with or without it
Could be something specific to T-Mobile and in this case that's why I don't see a difference
