How to disconnect GPRS?

How do I disconnect a GPRS session if I want the phone to use a wifi signal instead? Is there any way of telling the phone to always use wifi in preference to GPRS if possible?
The shiny new phone has just arrived, so lots of questions!
TIA

Hmm well I'm not sure if this works on Rhodium, but on many HTCs keeping the 'hangup' button pressed for a few seconds will disconnect cellular data connection.
If not, go to "Comm Manager", this should also have a button to disconnect it.
If that doesn't work, there's always datadisconnect.exe in \Windows (though that would be a silly thing to do every time )
Anyways, if you have a Wi-Fi connection, all connections made after that point should go through Wi-Fi automatically. Existing connections will keep using cellular data, until they are de/re-connected, unless the program asking for the connection specifically requests to use the cellular connection.

No luck holding down the Hangup button - I tried holding it for 10 seconds and the GPRS session stayed open.
I'm concerned about the situations where I think I'm connected to wifi but there's been a DHCP problem or something, and the phone quietly goes and uses GPRS instead (so the wifi icon is shown at the top, but there's actually no network connectivity via wifi).
Does anyone have a good solution to this?

There is an app available called "NoData" that lets you switch GPRS/3G/HSPA off. But you have to switch it back on to use it again...

I just found an option to configure the Hangup button so that it turns off GPRS, so problem solved! (by default it locks the handset)

You need to do some "RegEdits" to obtain this.. go here...
HKEY_LOCAL_MACHINE\Comm\ConnMgr\Planner\Settings\
add a DWORD called "CacheTime" with value of "60"
then add "SuspendResume" as a string with "GPRS_bye_if_device_off"
obviously minus the ""'s

beware that tweak breaks simultaneous voice and data

I've never had any problems with it, when I have a 3g connection active I can make/receive phonecalls and keep the data connection live. I reguarly download files while on calls and they have finished by the time I hang up...?

What exactly does this tweak do?
I actually managed to configure the Hangup button to close the GPRS connection using the standard Button Settings menu, but I'm curious to know what your registry settings will do.

This will automatically disconnect the GPRS after xxx seconds (60 in the above) if GPRS is not used.

Enabling 3g

I have just upgraded from a Kaiser to the TP2.
Using comm. manager on the Kaiser I could manually select 3G to be on or off.
I installed advanced config manager and enabled the 3G tab in comm. manager but it remains greyed.
Any data connection I make appears to connect in Gprs mode with no 3G or H icon displaying in the top bar.
How do I get 3G working on the TP2?
Am I missing something here?

It automatically goes to 3G if it's available. I don't get 3G in my house. But you don't have to do anything, it's automatic.

T-Mobile removed the icons for the mode. They only did a half-ass job though as the mode shows up once a data connection is established over the bars. Oops! I think this is an attempt to hide the fact that on the roads and byways, most of T-Mobile's network is still GPRS - not even EDGE!
Find one of the Icon packs here on XDA - they work. It will connect in 3G automatically if its available. You can shut that off (doing so saves battery if you're in a known no-3G area as it won't search for the signal) on the Phone settings option if you wish.

T-Mobile has the icons for the 3G mode. It has the "E" for Edge and "3G" for 3G.
It automatically connects to 3G, there's no need to search for anything. The only reason you'd want that is if you want to NOT use 3G.

Yes and no.
The "standby" icons for data mode available ("G", "E", "3G", or "H") are missing from the T-Mobile load. The proper mode does identify over the antenna bars once a data connection comes up, but in data-standby, its missing.
This is an intentional omission as the standard Icon pack from HTC includes these. If you load one of the icon packs off XDA they will "magically appear."
I like knowing what mode is available (not just in use, if any is in use) so I have one of the other icon packs loaded - plus I think they're far more pretty

OK thanks. I agree, I also want to know what mode I am currently using. Can you recommend one of the icon packs?

3G / HSDPA Selection

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

You're welcome

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.

Here's How to Toggle 3G On/Off on Tilt 2

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!

Disable Data Connections

Please don't flame me for not searching an answer for this, but I've been looking for 2 hours without success for a solution.
I have a Touch Pro2 that is for a buddy, so not even my phone, and she has no data allowance in her contract, so any weather lookup, microsoft My Phone or internet connections are going to cost her dearly till she sorts out a new Sim & contract.
Is there an easy way to turn data connections off, leaving the SMS service alone, then to switch it back on in the future when the Sim is changed? I know that on my own HD2 if you simply turn off data connection in the comm manager it switches back on when the phone is reset or thinks that data is needed.
I'd appreciate any help or pointers please! I'm going blind on these forums!

Here you go Try this. http://www.modaco.com/content/pocket-pc-software/246171/new-free-utility-nodata/
it is called NoData

Excellent! Thankyou! and this will survive soft resetting with the data still disabled, and allow SMS but not MMS?
Thanks for the help. I might actually have this done by the time my buddy is due to pick it up now

I think it does. I never used it so I can't say anything about it.

Open up the settings menu / connections and delete the data settings for Internet. It won't connect.

B-I-N-G-O-----spells Bingo!

Also you can search for 1 minute auto gprs disconnect

another good solution is to:
menu>settings>Connections>connection setup, change your country to other country. GPRS will invalid. still SMS and call can be working perfect.

Can't find any of those settings

I can find neither of these settings on my Energy ROM (which I flashed right after I got it).
I also found this, which would be my preferred solution - if I could find it. :

I did ask this in the Energy ROM thread, but nobody answered me there. But I am looking for a general solution (without extra software), since I'm not sure I really want to stick with this ROM.
Thanks in advance for your time!

It is great! You can enable disable conections (Internet, MMS, WAP etc.) Also is soft reset resistant =P
