recently got my HTC Hero I am with Optus (Australia) all the time when it says 3G at the top of the screen the connection is terrible (speed tests are slow etc) however if that says H i get more bars and super fast connection
if i use just 2G its just plan slowand not usable for VOIP etc
I am wondering is there a command i set to say only use H which i am guessing HSDPA?
Thank you
OzJames
The phone automatically uses the best connection available to it.
If it's not showing H, you're not within range of HSDPA service.
check on the market and download an apps called "any cut".after u install it open it and create a short cut for phone info by tapping on create a shortcut then choose activity then phone info by scrolling down to the options that says phone info.now go back to the short cut created called phone info and open it and scoll down to set preffered network type.the phone has a default settings to wcdma preffered.tap on the pull down menu and choose wcdma only and press on the back key twice to go to the home screen .this keeps your connection on 3g or H but will reduce in areas you cant get 3g or H.WHEN YOU GET THESE CONNECTION PROBLEMS CHANGE IT TO GSM ONLY.hope this helps

I don't understand, what is the purpose of doing this?
Like I said above, the phone will always use the best connection available (unless you set it otherwise in the options). Why set it to WCDMA only?
If you're in range of HSDPA service, the phone will use it.
Maybe I'm missing something, but this makes as much sense to me as asking how you can download more RAM to your computer

actually it would be like setting the computer up that it would only use a fast internet connection, and if it is slow not to use it at all. would be like connection fast -> page loads, connection slow -> page is not loaded at all.
hs(d/u)pa is an extension to the umts standard. if it is not available in the cell you are using there is nothing to do about it. if you have gsm with edge availabe that might even be faster than a bad 3g/umts connection, but that depends on many factors.
Works perfectly thank you
Its much more stable now

Heya, I'm also on Optus in Australia. The problem thatyou have described is actually really common with Optus users. Optus has way too many customers and have overloaded their system. A easy work around for a more stable connection is to change your APN from internet to yesinternet hope this helps.

I frequently used the Phone settings on my Treo 750 to turn off 3G in the Band settings tab when I wasn't browsing the web or downloading files. It extended my battery life tremendously. So I was bummed to see this tab missing in my new Tilt 2 Phone settings. Well, it's there, just hidden.
Navigate to
HLM\Software\OEM\Phone Setting\ShowUMTSBandPage
and change the default from 0 to 1. Now when you go into Settings/Personal/Phone the Band tab is exposed. To force GSM only and save battery, change the "Select your network type" drop down to 'GSM'. But here is where I need some guru help. When you try to OK this change you get the following message:
"If you change the bandset setting, the PDP context/Data call will be deactivated. Do you want to continue?"
I choose Yes and everything seems to be OK. The phone stays in GSM mode and I can still surf the web and get my push email and phone calls. To change back to 3G (if available in your area) just select 'Auto' in the drop down. You will again get that same warning...select Yes. Obviously you shouldn't ever select the WCDMA option.
Now, if you want to create a quick shortcut to that tab and add it to Mobile Shell or whatever UI you want, create a shortcut with this in the target line:
\windows\ctlpnl.exe cplmain.cpl,20,3
For those of you worried about the PDP warning, here is some info I found on PDP context. Maybe you can tell me what it means in english.
PDP (Packet Data Protocol) context is a data structure, which is created on both the SGSN and the GGSN of the GPRS core network and is used to contain the subscriber's session information when the subscriber has an active IP session over GPRS. When a GSM or UMTS mobile user wants to use GPRS, the handset must first attach and then activate a PDP context. The process will allocate a PDP context data structure in the SGSN that the subscriber is currently visiting and the GGSN serving the subscribers access point. The PDP context data structure will store the subscriber's IP address, the Subscriber's IMSI, the Subscriber's Tunnel ID (TEID) at the GGSN, the Subscriber’s Tunnel ID (TEID) at the SGSN, and the Subscriber’s tunnel ID (TEID) allocated by the GSN. Through the PDP context data structure, the GPRS core network knows how to route tunneled data between the mobile phone and the IP network (e.g. the Internet).
Well it sounds to me that when you are making that switch it is dumping your current session & aquiring a new one.
It would be nice ot hear what other believe would be possible consequences, but it sounds to me that if you had an active browser session (or phone call), you would lose it and in the case of the browser session any session variables or context about your web session would be lost & you would need to refresh your browser.
I have done this reg hack, and I never get that msg. I use gsm because it has a better signal where I am cause the 3G is just about dead till they put more cell towers up, but I can switch between auto and gsm, and hit ok, and I never have gotten that msg. I am using the tilt 2 on ATT.
OK, forget my original post because there is an easier way on the Tilt 2. I was browsing through all of the .exe's in the windows folder and ran across CMBandSwitching.exe. Just make a shortcut to this executable and there you have it.
U could do that, but I found that by sliding to settings/communications/phone and then scroll to the bottom you can choose band.
Don't worry about the PDP thing. All it does is force the phone to reestablish a data connection. If you had anything currently using data that will cut it off until it reestablishes the connection.

Good find. I like to leave 3G off unless I actually need it
3G On/OFF
This is funny but my AT&T Tilt 2 in GSM mode or let's say when 3G is off has a better coverage!
nice find, but is there anyway to get this to work for CDMA users?
sorry, a neophite here, how do you "navigate" to HLM/...., do you mean regedit? and how to do that too? my phone is htc tilt 2--and thanks a lot!!
OMG Thank you! You don't know how much I resented not being able to disable the 3G band like I could with my Hermes. Like most people replying, I also have issues with 3G reception in my area and this was exactly what I needed. This should definitely be included in the tips/tricks sticky post.
Why dont you use the nice little function that HTC has put on the device?
This is what I did on my htc touch pro2:
Browse to Windows/ on your device, and run the program "CMBandSwitching"
Nice little program which allows you to toggle between Auto (3G), GSM, WCDMA, and change band freq.
Just Copy this program and paste a shortcut into your start menu.
Then you can also put a shortcut on your home screen.
or you could just use one of the many 3g com manager cabs floating around that lets you toggle 3g from the comm manager tab
just install NoData from Modaco and then you re set
I enabled the Band tab in Phone settings and now I can have better reception in a couple of areas where 3G has a very poor signal. Great...
Now, if I shutdown the phone or go to Airplane mode while GSM is enabled, on powerup or on coming out of Airplane mode the phone will again go to 3G. A quick check on the Band tab shows that GSM is selected, but the phone is in GSM.
Is there a way to make this selection actually survive a power down or Airplane mode?
Thanks!
I have a problem with setting android to only use 2G networks. I can tick an option under settings "Use only 2G networks" but after i leave the settings menu it gets "unticked" again threfore i,m constantly on 3G which wouldn't be a problem but in the areas where there is no 3G signal android loses signal and wont connect to 2G network. I can turn off 3G under winmo tof orce android to only use 2G networks but it takes time. My question is can anyone successfully setup their android to use only 2G networks?
Same Problem
I´m having the same problem and for me it´s worse because it drain my battery really fast (don´t last more than 4 hours).
Could somebody please fix it as soon as possible because this way is really difficult to use android as main OS.
When I put a Sim Card that doesn´t have 3g I don´t have this battery problem.
I hope somebody could help me with this problem.
could someone please look into this? 3G kills my tilt realy fast too. this is the only thing stoping my from using android as my main os.

Try this:
$ su
# rwsystem
# nano system/build.prop
Find the part that says something about default_network=0. Try changing it to 1. Save with dpad-center+x, then y and enter.
# rosystem
Restart your phone to have it take effect. I'm currently trying out the value 3 which is "use GSM or WCDMA, whichever provides the strongest signal" and it seems to work better for me. Before I often had switched to Roaming after calls and somethings loosing connection completely, but I have only tested it for a short time so I'm not 100% sure if it helped or not.
Next release will include scripts to change this and some other things easily.
Oh, and the value 1 is supposed to be "GSM only" so it might help.

HELP!!!
I have tried everything here and still no 2G. I love android but battery life sucks. There has to be a way to force 2G all the time. 3G is great but if batterylife will suffer so badly I want to turn it off perminently. Does anyone know how to do this? I'm using VaniljEclair RLS7c and I have been messing with the scrips in the update and still nothing after reeboot.

I have tried everything too with almost all builds (1.6 2.1 and 2.2). My opinion is that ro.telephony.default-network command do not work on Kaiser. If ro.telephony.default-network is removed from build.prop nothing happens. Maybe TelephonyPprovider.apk is something to do with 2G 3G switching.
Bump... Please someone help us!! There has to be some hack we can try.
Please help us!!!
I agree,
Would be great to be able to force certain networks. If you look at the power usage/ per network the faster the network the more power it consumes. I'd like to be able to by default use the low speed and switch it to fast when I'm really using the phone. My EVO has a 4G widget switch. If it didn't the phone would be worthless to me as 4G in my area is not great. 2hrs 4G on (with no 4g network) = -40% battery... Love to do the same for 3G as that would save "about" 20% more battery life alone. I might get a whole day of use without charging...

As far as i know apndroid disables both 2g/3g connections and we only need to block system from using 3g connections leaving 2g still connectable.
Has anybody seen this before?

I've tried that a while ago and it didn't work for me.
I've bin going thru htcgeneric-ril.c (source of libhtcgeneric-ril.so), provided in another topic and noticed this lines:
Code:
switch (rat)
{
case 0: at_rat = "1,2"; break;/* Dual Mode - WCDMA preferred*/
case 1: at_rat = "0"; break; /* GSM only */
case 2: at_rat = "2"; break; /* WCDMA only */
}
Could there be a solution lurking in those lines to ongoing 2G/3G switching problem on Kaiser devices with Android?
Those look like the settings from the phone information screen in testing, it's certainly the right area to be looking in.
Question: who's gonna be brave enough to hack htcgeneric-ril.c and recompile that lib?
I already asked n2rjt to do it, if it's possible - still waiting for his reply.
Hey I just came from Galaxy S and there is a way to disable Hsdpa in there which improves battery life amazingly....
I was wondering if there is a way to do that in Desire? (for my city 3g speeds are faster than hspa for some reason)...
Also is there a way to select which band the phone is connecting by 850 vs 1900 ... or to see what it is using ?
any help would be appreciated
It's in the settings someone in network
There is also a widget to totally disable mobile internet which I use to save battery
Sent from my HTC Desire
Go to Settings > Wireless & Network Settings > Mobile Networks...
That's pretty much what you can do with the Desire as far as mobile networks are concerned. GSM phones normally switch to different frequency bands depending on where they are located and in the Desire I don't think you can select which one to go for (besides it's an unnecessary feature in my opinion)...it just does it on its own. Maybe there is an app around that let's you do this?...
As for viewing which band you are on....you can't do it on a standard ROM but there might be custom ROMs or an app that let's you do this.
Update: Some apps that might interest you => 4G, CDMA, GSM & Wifi Map Viewer from Sensorly.com
=> Open Signal Maps Beta from Staircase 3, Inc.
=> Antennas from mpoly
=> Quick Settings (maybe..)
mmm none of those do anything like it...
all those either just shut off data or turn it on... im not sure if anyone has used the galaxy s
http://forum.xda-developers.com/showthread.php?t=837716
this is what im talking about... saves the phone a LOT of battery by just forcing it to use 3g instead of hspa ...
i think developers can prolly make more sense of it.. i mean if they have a way.. there has to be one in other devices ...no?

Ah, so you have a Galaxy S.....unfortunately, this is a HTC Desire forum, so it would be better if you posted this in the Galaxy S forums. You may not find the answers you are looking for here as this forum mainly handles a different device to the Galaxy S.
What I said before is only applicable to the HTC DESIRE. I thought you switched to a Desire when you mentioned you came from a Galaxy S, but I was mistaken. The apps I mentioned as mainly for monitoring the 4G, 3.5G & 3G (i think 2G too) coverage. If you are looking to switch between them (i.e. turn HSDPA off and turn 2G on) I am sure there is a way to do so...on the Desire this can be done through the Mobile Networks settings...
And no, I'm not familiar with the Galaxy S....
no i had the galaxy s... (i posted that for reference as to how its done on that)...
and ya those apps just toggle just 2g vs 3g...
im looking for a umts vs hspa toggle... (3g vs 3.5g).... because umts takes way less battery than hspa does...
tried to mess around in the band setting screen but couldnt find anything
SOLUTION
what you need is to edit /system/build.prop file
here are my settings:
ro.ril.hsxpa=0
ro.ril.gprsclass=12
ro.ril.hsdpa.category=1
ro.ril.hsupa.category=1
after doing the and couple?... of restarts H icon changed to 3G and it really does save battery significantly and speed is pretty much enough for browsing or email
would have thought if battery life was vital then you'd disable data completely tbh
This is somewhat network dependent. Here in Sweden I know of one network that will have you at HSXPA (H) as soon as it is possible. My network on the other hand will set to 3G when WCDMA is detected and set to H only during data traffic.
And then G if only GSM is detected.
I disable data via widget if I want to save power even further. Not that it has that much impact. There is a setting under wireless and network > mobile network at the bottom : ativate mobile data (this is translated). This setting will force the data connection to be active even if unused. You have to experiment here what setting is best for your network. On my network, if I remove the tick here (data connection will let go if not used and reconnect when needed) my battery will drain quicker. Providers with other policies might give different result.

Thanks! Very useful! For me it was only necessary to change the "ro.ril.hsxpa=0" line, then do a couple of restarts (to make it clear, a single restart wasn't enough, HSDPA was disabled only after the second restart for me).
I have problems getting a 3G reception at work. My desire displays the H symbol but just doesn't connect to internet at times. If I manually switch to 2G I can connect. It's really slow but better than nothing! I can leave it on 2g all day but as the H signal works intermittently I like to try the 3g signal first before switching back to 2g.
What I would like to know is if there is there a way to change the minimum H signal the phone has to have before it goes down to E. My phone seems to prefer H even if the signal is too low to connect.
Can this be changed?
Yes.
Go to to the secret menu *#*#4636#*#* and select phone information.
Scroll down to the bottom and change
set preferred network type to GSM only.
I think this is a good idea to put through for the already excellent "Toggle2G" app. Thanks for bringing it up

Thanks, didnt know about the secret menu!
Going by the word preferred it sounds like it is what I am looking for but 'GSM only' makes me think it wont switch to 3G.
Does this mean it disables 3G completely? Couldnt I do that just by going into settings and selecting use 2g networks only?
Edit
Just searched GSM only and found this thread http://forum.xda-developers.com/showthread.php?t=688492. A good explanation of each setting, think GSM auto (PRL) is what I am looking for as GSM only is just 2G but I can usually get a 3G signal so I'll give this a try.
When I leave my apartment until I disconnected from WiFi, I getting into the elevator and the data is searching for network and will not find any.after I get out of the elevator, it connects to 2G and stay there for long time.
If I switch WiFi off,, before I get into the elevator, it will connect directly to 4g and stay there(and this is how I like it).
But most of the time I forget switch off the WiFi, so I have to wait something like 10 minutes to get 4g connection.
Any way of disabling 2G, but leave 3G & 4G?

You could try dialing *#*#4636#*#* which will open the 'Testing' settings and then navigate to Phone information and scroll down until you find a little drop down box which you can select which network types you want to run. I myself use CDMA/EvDo/GSM/WCDMA/LTE Auto which switches between those when it needs to but if you only want to use 4G then you can switch to 'LTE only'.
Goodluck and I hope that does what you wanted!
Edit: I just realized that that number may not work on all phones, if that fails and you cannot access it with that then the only other method I can think of is to download Pimp My Rom from the Play Store and once installed open it and navigate to Tools < Scroll to the bottom & tap Device Hidden Menu > Access Hidden Menu. Please if you decide to wander around in this app then make a Nandroid backup first as this app is still in beta and very unstable, I recommend just using it for the device hidden menu options until you get what you need done.

I had problems once with my phone only using 3G and using this to set it to allow 4G solved my problem permanently, hopefully it won't "reset" with yours, though I've never heard of that issue happening so it may be uncommon.
