htc band settings on 3 network!?

Hi.
I have an HTC Touch HD on the UK 3 Network.
It works fine with texts and calls n 3g but whenever I need data for an app etc it ignores a great 3g signal and tries to connect on HSDPA instead.
now this might not seem like a problem but it often switches from full 3G bars to one bar on HSDPA to check my email. this can take 5 to 10 seconds when it could have just done it on 3G.
what gives? am i using the right settings?
start/settings/phone/band
Network Type "Auto"
GSM/UMTS band "Auto"
when i was on Vodafone it would stay on the best choice ie HSDPA instead of all this swapping about.
I hope this is the right place to ask. not a major problem just a frustration.
thanks

In common with many (all?) of the five networks, 3UK has recently switched their handsets from staying on HDSPA to "only" 3g, but automatically changing to HSDPA when data traffic occurs.
HSDPA demands extra bandwidth to the cell. There might be a second or so delay while the handset re-negotiates the extra protocol, but it's done to give extra capacity on the cell, allowing more space for 3G voice calls, while ensuting your data speeds aren't affected by push-email or similar low-bandwidth devices using an always-on HSDPA protocol.
In short, it's completly normal and pretty standard nowadays. Keep your phone on Auto/3G, you can't force it to HSDPA only.

Data constipation? Irregular data movements? Constant disconnects?

Symptoms
- You cannot maintain a constant data connection. The connection is often lost or dropped.
- HD2 reception indicator dances between G to 3G to H despite showing good reception, and user remaining stationary.
Counter measures - No cabs or registry tweaks needed.
Presented in the order I would try them. If the lower number levels don't work, then move up a level. These are offerred as advice from a UK based HD2 user, though may work for you elsewhere.
LEVEL 1
- Go to Comm Manager > Wireless Controls
- Turn the Data connection Off then On again.
This will usually get you back and running again faster than waiting for the HD2 to sort itself out.
LEVEL 2
- Go to Settings > All Settings > Connections > Advanced Network
- Disable HSDPA/HSUPA
This will stop your phone attempting to use '3.5G' and will mean that you only use 3G.
Remember to re-enable HSDPA/HSUPA when you are in an area with better reception.
LEVEL 3
- Go to Settings > Wireless Controls > Phone - Change phone settings
- Move down to Other Options > Band - Change baseband
- Change Network Type from Auto to GSM
- Change Band frequency from Auto to either GSM (900+1800)+UMTS or GSM (1900+850) . To make the decision, you need to know the GSM frequency your operator uses. If you don't know, you can just try both of the GSM options and see which works. No damage will be done by using the wrong frequency first time, and you can change back.
This will disable 3G and force your phone to use 2G. Most operators have decent 2G networks, so you shouldn't have the disconnects anymore, but you will have slower than 3G potential speeds.
Remember to change your phone back to Auto for both Network Type and Band Frequency when you are in an area with better reception.

Thanks for the heads up... will have to try some of these. I find it most annoying at times...!

Thanks for the advice, I do find those issues annoying. What are the benefits of using 3.5G? If they're aren't any major advantages and turning this off helps then I may as well leave it off.

The problem with this is that it b*llockses up your push email settings, if you use the phone to get email from an Exchange server. The better approach (assuming standard configuration) is to press and hold the power/end-call hard-button. That brings up a menu of four choices. The last of those is "terminate data connection". Click it. Anything the phone does which requires the data connection after that will automatically reactivate it.

3G 2100
These tricks may solve the issue for many but not for me because I'm in a 3G 2100 only network so I cannot switch to GSM. I will try to disable HSDPA/HSUPA to see if that works though.
The weird thing is that the issue occurs almost exclusively when I'm logged on an IM client and the phone stays in sleep mode a few minutes (say 15 min or so). After I wake up the phone the signal seems ok but the data connection is lost (IM, browsing, mail, weather update, etc.). It doesn't happen every time but very often, several times a day.
If I don't log on any instant messenger app the data connection is stable, especially with the new 1.66 ROM (I tried both Duttty's custom and official). In this case I lose data connection very rarely, in fact I din't even remember the last time I did.
Can anybody provide an explanation for this, what is happening with the connection between the IM server and the phone during sleep?

If your network supports it, you should have higher potential data upload and download speeds through using 3.5G (HSDPA/HSUPA).
In reality and every day use, on many networks you probably wouldn't notice the difference between 3G and 3.5G.
I'm on Virgin Mobile, which piggybacks on T-Mobile's network here in the UK. My speedtests in central London, show virtually no difference between me using 2G, 3G and 3.5G!!!! Which is ridiculous. The main difference I get as a HD2 user is much more stable data connection on 2G vs 3G/3.5G.

Any way to set 3G as permanent internet so it doesn't go to HDPSA?

I've been having internet troubles since i got my Hero a few weeks ago.
It seems to jump between '3G' and 'H' when I use any applications using the internet. This means that pages often fail to load/download, or appear slower than 2G connection speeds.
I think this is because I'm in an area which can just about receive HDSPA speeds sometimes, but not consistently, so I was wondering if there's any way to set the internet to stay at 3G and not attempt to connect to HDSPA? When I'm in areas where the best speed possible in 3G, the internet is infinitely faster than when it's jumping from 3G to H and back.
Thank You!

I'm not sure on the phone itself but from a network perspective you would need to ask you phone provider to change your QOS on the HLR (network control and provisioning) to a non HSDPA entry, eg t-mobile uk QOS 1201 = HSDPA 3.6

it doesn't work that way (the hlr qos profile). you can only set the maximum speed there, not the RAN technology which is used. i don't think there is anything you can do, the phone attaches to the best server (=cell with strongest signal), and if that cell supports hsdpa it is used for data transfer. as hsd(p)a is only an "addon" for umts i don't think that your connection would be better on the same cell, even if you were able to force umts usage. bad radio reception is bad radio reception... it is not uncommon that a stable EDGE connection works better than a weak umts/hspa signal, have you tried switching to 2g?

of course you can, thousands of sims on networks are unable to use hsdpa because of a low qos, on t-mobile's uk system if you do not provision the web and walk plus SOC on the account the service order does not go through and they are unable to use HSDPA. I dont have a HSDPA qos and I dont get a H but if I use the sim that came with it I do.. best thing to do is give the networks tech support a ring with some times and locations and ask if they can look at what ever reporting system they use and look at network statistics at the time. Best to look at the sgsn;s and look at the stats at that point.
It doesnt matter if the cell supports hsdpa, hsdpa on the cell itself is only a capability to go back through to the msc. a footprint on a 3g cell will keep the closest strongest users when it hits max capacity, if you are on the outskirts you ill lose out.
the more you complain to the provider the qucicker they add some higher bandwidth lines to th local exchange or hub..
Might simply be a congested site, if so it should report itself...
naughty naughty trx

ahem... hspa is RAN (as in Radio Access Network) technology. it is applied to the communication between the handset and the node b, not anything behind the node b (not sure whether the rnc needs to be aware of it, but that's it, no msc involved). i am not sure whether the simcard needs to be hspa capable, but i have never heard of it. and i do provision sim cards for a living...

You are rightt hsdpa as a technology does get implemented between the mast (node b) and the handset.. what is added between the RNC and the node b is the LUB this is an added control mechanism, this kinda makes sure no data is loss occurs when the node b's buffers are overflowed! this is not a fool proof system, RNC? it could be a SRNC controller,, anyway you are right in what you say but as i have worked within this area i do know that when i was saying "SIMS" I didnt mean the actual sim itself i was referring to sims with old HLR profiles that cant access hsdpa! most pay as you go sims cant on tmob uk this stops them going £1 a day unlimited handset internet and hammering the sim in a dongle!! Im a big fan of provisioning btw! geeky as it sounds the complexity of mass provisioning failures interests me!

[Q] Option to use only 3G NOT HSPDA

HI all!
Right now I am using [Build][10.12.2010][NexusHD2-FRG83D V1.8 PPP+RMNET][Kernel: hastarin r8.5.3_oldcam] and that is quite ok for me.
However I havent found anywhere on that build an option to disable HDSPA speed.
What I would like is accept 3G but disable HSPDA. Now I only have a change to disable 3G totally and only get 2G. Basicly area where I live is keeping me a situation that phone is very often trying to connect HSPDA but then changes is 3G speed. It causes me time&battery drain.
I have found a solution to force phone only use 3G but that is what I wanted. 2G and 3G are ok but I want to disable HSPDA.
Anybody could help me?

Up, Up... anybody have same kind of need?

i also need same help regarding this, reason is my data plan only use 3g (umts) and not 3.5g (hsdpa)... but my android always switch 3g to hsdpa back and forth and drain battery much faster
is there any tweak/program/widget/application that can enable 3g (umts) only?
windows doenst have this problem cause in winmo i can switch the option easily (enable/disable hspa)... but android dont have this kind of thing

I have the same problem. I don't even have HSPDA where I live, yet it tries to connect, fails, and then connects to 3G. It's a very time consuming processor to wait for the phone to do this when I am just trying to load a website.

Yes.. maybe it will not drain much memory but.. who wouldn't want a fast internet..

Afaik Hsdpa uses the same radio towers (or whatever the name is) as Umts... just different software. so there should be no battery drain caused by this.

1. Go to your dialer
2. Dial *#*#INFO#*#*
3. Click 'Phone information'
4. Scroll down to the first dropdown selection and set according to your preference below...
For simplicity, there are two main types of cell carriers, GSM and CDMA.
The following popular data communication technology is associated with each cell carrier type:
GSM = GPRS (2g), EDGE(2g), UMTS(3g), WCDMA(3g), HSDPA(3g) {Cell Carrier examples: AT&T and T-Mobile}
CDMA = CDMA*(2/3g) EV-DO(3g) WiMax(3/4g) {Cell Carrier examples: Verizon and Sprint}
Now that the general stuff is out of the way, here's my take on the Preferred Network types:
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (Maybe the Samsung Galaxy S will take advantage of this???)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this

uhh... maybe you dont catch what us mean....
when umts change to hspda (icon change from 3g to H) then it use battery power.. in my case i use 3g (umts and not 3.5g or hspda )data plan only... but android keep searching hspda signal and THIS is when battery used the most (the process) and EVEN when my area have 3.5g covered but because i use 3g only data plan... then the back and forth process (3g<->H) will kep coming and rdrain my battery fast
so... we look for any kind of workaround so our android keep stay in 3g (umts) and not drain any unnecessary battery power searching for hspda
btw sorry for my english

i use this thing before and no luck
i use "wcdma only" as the option and android still process 3g and 3.5 back and forth, maybe android "thinks" 3g/umts and 3.5/hspda as the same?? android categorize umts and hspda as one big fat 3G network
i wonder why newer os like android doesnt have this kind of feature in winmo there is an option :
disable hspa = so hspda disabled.. AKA 2G or UMTS only
enable hspa = enabled hspda, hspa, hsupa etc.. AKA 2G, UMTS and HSPDA

try this settings
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.

isnt cdma auto (prl) used exclusively for cdma phones? (those phones with evdo and wimax thing) and not used for our hd2 (GSM)???

C'mon how this is impossible with newer phone software??
This feature has been in WinMo and Symbian in many years!!
It is really frustrating that almost every time my phone is trying to make HSPDA connect and then decide 3G is enough and possible. It causes some delay and sometimes also timed out errors.

agreed
my android keep going back and forth between umts 3G and hspda 3.5G like some clueless kid while 2 experienced guy (symbian & winmo) laugh at him

i know this is a old topic
i have still this issue
my phone is switching to hsdpa an back to 3g after a few seconds
when the phone is connected to my slow wifi connection everything works fine and i can use it for 3 day's
when it is connected to hsdpa my battery is empty after 15 hours and the voip connection is not working properly (i need to start a ping to some server first to keep the connection alive so i can call with voip)

I just came upon this thread, but I don't have this problem, so I can't really test it out this theory. But my thought was, what if you just went into the build.prop file and edited the ro.ril.hsxpa.category settting from ro.ril.hsxpa.category=2 to ro.ril.hsxpa.category=0. I just tested it out and it never jumped from 3g to H. My only concern is that you wouln't get the fastest speed you could be getting. Test it out and let me know though.

at this moment it is not posible to root my phone (SE Xperia pro with latest firmware)
so i am afraid we need to wait to test this
but thanks for the hint

H910 Access Point Issues?

Hey, guys. I'm new here, and definitely a noob.
Just a quick backstory, I live in a rural area with only satellite internet connection, aside from using my phone as a mobile hotspot. I do quite a bit of gaming when I'm at a place with low latency internet, and have recently started using my mobile hotspot for gaming (laugh all you want, it works out fine for the most part). Unfortunately, living in a rural area, there is very limited service. I'm not completely informed on the lingo, but out here, I've learned that I can only connect to two towers (?). One is HSPA+, and one is 4G LTE. Obviously, only the 4G LTE one is good for low latency connections. I know that carriers have certain towers that they try to connect to before others because the others can cost them more. My phone usually defaults to the HSPA+ network.
I have found a way to force it to the LTE signal. By going into the hidden menu > Field Test > Modem Settings > PDP Setting > APN Setting > ATTNextgenphone > Bearer - LTE, and then saving. Usually, after about 20 seconds, it will switch to LTE service. Recently, though, my phone will attempt to not use that access point, and then remain with no 4G or 4G LTE icon next to the signal strength graphic, and I cannot connect to the internet in any fashion. I'm not sure if AT&T has figured out what I'm doing (I doubt it), but I just want to know if there is any way to combat this or to go about connecting to that 4G LTE access point in an easier way? Maybe there is some sort of root (?) I can do?
Any help would be appreciated.
* (?) <-- meaning I'm not sure if I'm using the correct wording or phrasing.
