I do not use UMTS so it would be nice to turn it off to save power, at least most of the time.
However the "Band" dialog contains only these:
Auto
GSM(900+1800)+UMTS(2100)
GSM(1900+850)+UMTS(1900+850)
UMTS(2100+800)
I found the corresponding entries in registry, ItemName[1-4] and ItemValue[1-4]. The latter are assigned to 0...3. It's unfortunate, in case of a discontinuity (say, 0,2,3,4) I would instantly have an idea what to do next
Is there a simple hack to fix this?
WM6 (5.2.1437), ROM 3.54.255.3, radio 1.48.00.10.
From your network type, select 'GSM' instead of 'Auto', which I'm sure it is on now. That will do the trick. You might see an 'E' if you service provider offers EDGE, but this won't be an issue, otherwise you will just see the 'G' again.
Great! Works exactly as you described.
(I will need to do some reading about WCDMA, to avoid similar misunderstandings in the future...)

Hello,
I know the place in the phone options (on the band page) where you can
change the network from GPRS to UMTS (3G).
But is this possible to do programmatically with RIL or TAPI or another API
on the pocket pc device?
Thanks for any suggestions.
I support this request; Many topics on the board cover erratic behaviour with JJ, and ppl return their device to no avail. Swopping to another operator often helps. The issues SEEMS to be a poor UMTS reception with a given SIM or location, and this results in JJ trying to connect to UMTS or even latching on to UMTS but with an abysmal signal. After more than 15mins (annecdotal) of this is fails to ever go back to GSM without a reboot.
Solution is to turn off UMTS, but that's darned inconvenient cos you OFTEN want 3G speed (mail, RSS, google/surf).
Here's a way forwards; can someone tell us what reg entry gets changed when we select GSM vs UMTS? I will then write a couple of .reg files that can be launched from iLauncher (or whatever). Buzz coule probably write a switching app like he did for BT.
i have the same problem
When i use my Universal at home, there is pretty low level of UMTS/WCDMA signal and full level of standard GSM signal. By default Universal changes between those two sources automaticaly. But in my case, the quality of WCDMA signal is often varying just around critical level. So the result is that Universal changes band to GSM and back. And then again. And again. And... Due this, there is sometimes not possible to make data connection, because Uni is so much occupied by changing bands back and forth...
I would like to find a better solution, than select only GSM manually in phone settings. Especially because i have to unselect it manually every time when leaving home :-(
Is there any way to set treshold value (i expect increase it) for automatic switching between WCDMA and GSM?
I still do not know how to switch from UMTS to GPRS and back
with some API function (or AT command) on the device.
If I get these Infos from someone that would be great.
Then I could write a tool that checks the signal quality
and the network status and if UMTS signal is too low
it will activate GPRS.
I think this can be done with RIL API but have not found
any infos.

Anything new aobut this umts switch problems??
I do have the same problems, often i am unable to make calls, always when umts is on...
would be happy to hear something,

Hi,
My TyTN uses to switch automatically between GPRS and UMTS network (when available). Unfortunately, the UMTS network I receive at my place of work prevent any call or SMS to be sent or received. Once I leave this area for another place (provided the signal is coming from another antenna), everything is fine, even in UMTS mode.
Local antenna failure has been confirmed by my operator, but this should not be fixed soon from their side.
My question is:
is there a way to prevent the TyTN to switch between GPRS and UMTS network (when this latter is available) ? Phone parameters allow to define two different bands but I found no way to prevent my phone to switch on the UMTS mode.
Thanks in advance for your help.
Get Bandswitch, it should do exactly what you want.

Also please search. This issue has come up several times. I just did a search using the Google sticky at the top of the messages list and got these results: and guess what the suggestion made above is top of the list

Thank you very much for your replies. I will try Bandswitch tomorrow at my place of work, where the UMTS network fails !
I just would like to say that I DID perform a search. But with the "Search Forum" tool instead of the Google sticky. I tried with the keywords "UMTS deactivate Windows Mobile" and the results were not that straightforward.
Sorry for the inconvenience.
start>settings>phone>band
set top box to gsm when at work, and auto when on good 3g area.
Didn't have time to browse all the posts on this issue but while we're waiting for the next useless hotfix from HTC, I tried to go with manual settings for the network and network type by doing the following:
1. Wireless controls>Phone>Band: Change network type from Auto to WCDMA. Left Band Frequency on auto. Done.
2. Settings>All Settings>Personal>Phone>Network: Changed "Network selection" to "Manual". Your device will search for all available networks. Pick your carrier/network from the list.
3. On the same screen as 2, tap on "Set Networks" and uncheck all other networks except your own primary network.
With the above change the phone will only have my home carrier to choose from (not sure if that makes any difference) and the network type will always stay with HSPA which is no problem for me in the area I live, in fact I want that.
Cant confirm if this does it since the issue occurs sporadic, but so far five days without any SMS stuck in the outbox which is unusual for me, used to get it every single day.
Obviously the above leaves it to you to manually manage the network settings as well as running H all the time may be a problem for some, but if this works as an interim (hopefully not permanent!) solution for some users it could be worth giving it a shot...
Cheers.
Rom:1.48.405.2 UK, clean install without any of the previous SMS fixes but including all the currently avail updates from HTC.

On mine under Wireless Settings>Phone is only has the options for sounds available?
Jammie: Doesn't sound like the right place. It's basically just the Comm Manager.
Thats right: Comm Manager/Phone then scroll down to Band to make those changes, then Done or Cancel and hit the Menu/Network or Advanced Network tab.
Bear in mind that if you select WCDMA only as opposed to Auto, then you will have no signal at all if you go to a non-3G area (of which there are still many thousands of square miles in UK!); overall its best to keep this at Auto for everyday use.
OK, I did steps 2 & 3 but on the first I had problem... Phone couldn't connect with the network with WCDMA, only with gsm, so I turned it from auto to gsm... I don't care about 3G
have tried all that and it didn't solve the sms problem for me...
can't find a thread here, but can I switch off 3G on a HD2? Optus in Sydney has no 3G reception sometimes. But the HD2 still thinks it's on. It can call out, but nobody can call in (gets msg 'phone is off'). Data/sms don't come in.
Optus admits it's their 3G, solution is to use 2G. I can't find the option
Touch tools
Touch tools will add an extra slider to your connections screen or if you look through the very first sticky in this forum http://forum.xda-developers.com/showthread.php?t=583638 under tip#58 there is a cab that just installs that.

i have turned off 3g on my phone to save me some battery
ps, tap the phone icon itself under the settings menu and not the slider (off/on) thing
I recieved this myself from HTC Support..
a simple program to do just that, turn off 3G.
No need to install, just put the file on your phone and run it (the .exe, not the .zip d: )

Is it a toggle? or does it just turn off 3G?
EDIT: This is just like the regular Data Connection Enabler / Disabler program at XDA.
Is there a registry entry to do the equivalent of what the 3G slider switch in the Comm manager does?
If anyone wants to do this (Set Netwrok to GSM) during XDA_UC through the registry
HKLM \ Software \ OEM \ UMTS
OpMode: 1
Supported Values
0 - Auto
1 - GSM
2 - WCDMA
Band Selection can also be done. Just look for the Folder "BandSelection" under UMTS.
You need to edit the value of BAND
The effect of this can be seen only after a soft reset or manually switching the network type or the bands. However the indicators (in the Comm Manager or in the Band Selection Utility) will reflect the change immediately even though the radio does not switchover to the desired Network / Band.

I support cezzarmicu with this, i do that often when i need my phone to stay longer without shutting off especially when i'm outdoors for longer times!
Simple procedure!
I've noticed that using the dialer code: *#*#4636#*#* we can access a debugging menu.
Tap 'Phone Information' and you'll see a slew of information about the current connection status.
As you can also see, there's a drop down box labeled 'Set Preferred Network Type:' which allows you to change the cellular network type(just like in the Mobile network settings Menu). This is great if you are in a location and have a data connection but aren't getting any throughput. But there's also a drop down under box under the same 'Phone Information' debugging menu, on the top right(three button) that gives you an option of selecting the radio band as well.
My question is, will there be a way to implement into custom Roms or kernels to allow the radio bands and network types to switch to the best frequency with most data throughput?
Walking through my house, I have dead zones. In those dead zones I have to switch to 800mhz and change my type to LTE/WCDMA. Could we have an auto search for radio frequencies and the individual bands on those frequencies or will I always have to manually change them?
Correct me if I'm wrong, but I think the "Select Radio Band" is set to "Automatic" by default, and changing it to something else (like "Cellular 800"), prevents you from going back into automatic mode unless you reset your modem (easiest via TWRP).

Usually the modem resets to auto when I hard reboot. Either way, the automatic setting isn't doing its job.
