Question regarding disabling Data connection GPRS (TP2) T-Mobile

I recently received a T-Mobile Touch Pro 2 cell. I'm NOT paying for web service and would like to only use Wi-Fi. If I disable my data connection under the communication manager, would this mean that I will not be using T-Mobiles web service and only my Wi-Fi? Can I still receive calls/text messages when the data connection is set to off? Do I have to worry about the data connection setting automatically turning on by itself for whatever reason?

Yes.
Yes.
Yes.
Flipping that switch manually turns off your phone's 3G connection, and you can still make/receive calls/sms. However, as soon as some app or process needs a data link (ones that don't/won't use the wifi connection), it will flip that connection right back on.

Which apps do I have to worry about flipping the connection on? I only plan on surfing the web and I don't plan on setting up my e-mail account. I only want to text and browse the web using my TP2. Thanks for the response.

Well Google Maps for one, it insists on downloading through your 3G data connection even if you're connected to wifi. There may be others that will ignore a wifi connection and fall back on 3G, I don't know off the top of my head, you can dig around here some to see if there's any reference to that (I know I've seen it, just don't have it bookmarked)

Yes, some apps are automatically enabling the data connection.
My solution:
go to Settings > Connections >
and delete the 'data connection' for your provider.
Their you could also go to advanced and choose which networks will be used for what type of connection; play with it.
The data connection isn't used for 'calls', only if you are calling over IP (skype e.g.)
With a program like SPB wireless monitor, you can see which connection has used how many bandwidth.

How do I go about deleting the data connection from my provider? I'm lost!

There is an easier way. Use the Modoco NoData cab and it turns off the data connection until you turn it back on. This way if you decide that you want to use the data later you dont have to find out and enter your settings again.
It works very well.
For those who want to restrict the data to thier home carrier ie: no roaming the Dynamic+ NoDataInRoaming is ideal as it automatically switches on and off when you enter and leave your home area.

Turning the data connection on or off

Hi,
If I read the HTC Desire manual page 128:
Code:
[B][U]Turning the data connection on or off[/U][/B]
...
Press HOME > MENU and then tap Settings > Wireless & networks.
Select the Mobile network check box to turn on the data connection; clear the check box
to turn off the data connection.
We can simply check/uncheck the above option to turn on or off the data connection.
Did you get any problem for turning it back on (from off) ???
Because I read the old HTC Hero (which has this option as well) has problem with this.
When you turn off data, and turn it on again, the phone cannot use data connection unless you soft-reboot.
Reference:

No probs with mine

I've used this method since last Saturday, saves so much battery on my Desire and when I want the net, I can turn it back on easily enough or if at home just use Wi-Fi.
No problems getting it to turn back on again.

Does this mean I'll have to manually turn data off if I want to use wifi?
Reason why I ask is because I checked my net counter and all my data has come from the data (3G) portion of my phone whilst nothing via wifi.
Probably me being a bit naive as I thought once wifi was on the phone would know to use that automatically as opposed to 3G...
EDIT: Just had a look on my phone and under settings --> wireless and network --> mobile network (uses phone for data connection when wi-fi unavailable) is checked...so would I be correct in assuming that when wi-fi is available data won't be used??
and in Mobile Network Settings --> enable always-on mobile data (uses more power on some mobile networks) is checked (could this be the culprit?)...

Thanks for your feedback, that is certainly a good news.
Btw, does HTC provide a small widget to toggle this easily?
Or you must go through the settings -> Wireless Network -> ... ?

there is a widget you can add on your screen to do this (and others) goto widgets then scroll to settings hit the arrow on the right and you get several icons you can drop
airplane mode
bluetooth
gps
mobile network (data)
wifi

Press and hold the power button, it's an option on the quick list.

Data connection problem when coming back from Airplan mode...

I've stumbled on a strange issue.
If I switch the Desire to the Airplan mode when the Data connection is off (I use the appropriate HTC Data connection widget to do this), when I switch back to Airplan mode off, the phone is no more able to restore the data connection.
The only workaround found is to restart the phone.
Has anyone got the same experience?

Two questions.
1. When you say you switched off data connection, are you talking about syncing, wifi, mobile network, ... etc?
2. Why do you want to switch off data connection and turn on Airplane Mode? Doesn't Airplane Mode cater for shutting down all wireless?

1. I'm talking only about the "Data connection" option on "Wireless and networks" menu, that is switchable via a special HTC widget. Switching this option off, the phone is no more able to access to the GPRS provider. I often keep this option off to save battery life. I turn Data connection on, if I need to sync and access to Internet.
2. This is not the matter, just it happens. Eg. When I go to sleep, I turn the Airplane mode on, doesn't matter if the Data connection is on or off (it is possible that it is on) in order to avoid any disturbs (calls, sms, etc.).
I just wonder if this issue is a true bug of the phone:
1. Switch off Data connection
2. Switch on Airplane mode
3. Switch off Airlplane mode
4. Try to activate Data connection (for me it seems it's not possible without a reboot)

Had a similar problem which I wrote to HTC about: after the phone has been data connected via wifi and I leave the wifi network it often will not connect to data via mobile network (GPRS/3G), giving the message "connection failed" if I try to manually connect in the "mobile networks" section of the "wireless & networks" settings page.
It seems to have fixed itself now, and I think it's because I've since ticked the option to "enable always-on mobile data", which I had turned off to save battery. Give it a try.

Thanks yurikg, but on my phone the "enable always-on mobile data" option is checked, anche there is no mobile network connection problem coming back from a Wifi connection.
The problem I shown is probably caused coming back from Airplane mode.

The other possibility is Juicedefender which apparently is known to cause problems recovering a mobile data connection (recent update may have fixed this):

I've not juicedefender on my Desire...
I've in plan to do some other tests...

I have a problem with my Desire reconnecting to a mobile data connection too, but not when I come out of 'plane mode, its when I leave a Wifi covered area. It could be the same problem, triggered by anything that disables and then reactivates the data connection?
I have no solution yet, and I have contacted HTC support about it (still no reply). There is some discussion here:
http://forum.xda-developers.com/showthread.php?t=656192

I seem to be having this problem too when coming off WiFi connection, unfortunately restarting the phone has not righted the issue...

I'm also having this problem with the connections. Fine on the wifi at work and at home but not switching over to the mobile network. Apart from that the phone seems awesome! Soooooo much better and more fun than the HD2.

OK, my phone appears to have no network connection whatsoever in fact...

Have the same problem as well. Coming from Wifi and to mobile network only - I do not get any data coverage. This is for the Desire and I had the same problem with Legend.
I hope this will be worked out ASAP.

Well, my problems all sorted. Turns out I had to manually input the APN for internet, took me by surprise since no phone I've owned since 2006 has needed that...

Just had to put in the settings manually too. Seems there is an issue with some of them. Would put a link here but as i'm a newbie not allowed Just google vodafone apn settings for htc desire and hey presto

Same problem here, my Hero had it too. I found it did work when you switch to gsm only and back to 3g/gsm... Would love to hear good solutions.

Im also having the same problem.
If i try switching my connection from wifi to mobile data, my mobile data connection fails to work. A power cycle fixes the issue but if i try switching connections again, the problem returns.

Can I suggest to anyone still having problems getting their phone to switch to mobile data when leaving Wifi to view the following bug report on Google Code and to star it to help raise the priority with Google:

Mobile data turns on when wifi turns off?

I've noticed that whenever I turn off my wifi connection, the mobile data connection automatically turns itself on. This is quite annoying as I usually have it turned off to conserve battery.
Is there any way to disable this?
Thanks in advance.

No as the Desire is a smart phone which always needs a connection to the Internet to update - it's working as designed

Well if the user specifically wants to turns off the APN connection and keep it off until manually turned on, I don't see why that's such a big ask. I only want to have control of my phone, not the other way around.

I use Honolulu Team's Extended Controls to switch both wi-fi and mobile data off when not required.

I also use this, but if I have wifi turned on for example (with mobile data turned off prior), when I turn off the wifi the mobile data immediately activates without my say so.
There must be some way to disable this automatic connecting.

[Q] Concerns about data roaming

I hope I'm posting this in the proper category.
Namely, I'll be leaving my home country very soon and travel abroad and I will most certainly need to occasionally do SSH connection to my server over 3G, which leads me to data roaming. Now, data roaming at my carrier is super expensive, so I was wondering if there is a way to completely disable data while in roaming, but still be able to connect to 3G and EDGE when I explicitly tell the phone to do so (eg. for SSHing somewhere or checking in on Foursquare, refreshing Twitter timeline, etc).
I saw that there's an option to uncheck Data Roaming in Wireless & Network settings, but I would say that will completely turn off all data connections and NOT allow me to manually and explicitly initiate data connections. Is that true? Is there a way to make it connect to 3G only when I explicitly tell it to while remaining disconnected otherwise?

Allow all phone data settings on. Download APNdroid or similar (APN on off widget) from the market. Open app and set any preferences, then add widget to home screen. Activate by tapping on off on (or something like that). Green on, red off.
All it does is rename the APN settings so it "fails" to connect.

Your quite correct in that it will stop data connections, but why not turn it back on when you want to connect?, the other possibly cheaper option would be to, as long as your phone is not networked locked, buy a local PAYG sim with data and use that in your phone when you want to use 3G

Buying local sim would be wise option....

A local prepaid SIM is a good idea, far cheaper than using data roaming.
Additionally, to avoid background data usage, you might want to install Droidwall and allow only the SSH app to connect to the internet.

Because I want only that one application to use the data connection when I want it to, without all other apps opening their own connections for sync and other stuff, since I have a lot of apps and accounts that sync in certain periods of time (this is an Android device, after all ).

Exactly what I needed! Many thanks for the suggestion, I'll try it out!
