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:

When I read the HTC Desire user manual, it said that I need to turn on the "Data Connection" setting to have internet connection.
Well, this is understandable ... but, does it has automatic connection on demand?
On Windows Mobile, I dont have to specifically turn on data connection. Whenever an app is trying to reach the internet, it will turn on the data connection automatically.
And of course, it will turn-off the data connection automatically as well, when there is no internet network activity.
Does this also the same in Android?
It should turn on automaticly when you try to use online services...
But you can turn it on in Wireless & Network
You have to option to turn mobile data off, that is why it specifies that you need a data connection.
If you do not turn it off, apps that require internet access will use it with no further interaction.
By default MENU -> Settings -> Wireless & networks -> Mobile network was off on my device, meaning it would not connect to internet via 3G (I could still make/receive calls). However, I chose to use WiFi for set-up when I first started the phone, so maybe that's why.
Anyway, I guess that is the setting they are talking about.
Thanks for your information, but that raise a question:
When I switch off the data connection and also switch off the background data option.
Will the HTC Weather widget (and other similar widget) still work with auto-updating periodically?

NO... they need either 3G or WiFi connection to update...
So, that means ... those apps cannot wake up (turn-on) the data connection automatically if needed (on-demand) ...

I do remember the old days of the HTC Hero which had the option of background data usage. I think that was more to do with the version of Android than anything else. I recently had the Nexus One and on the new 2.1 version of Android, you can either switch data on or off, no automated connections on data usage.
When the phone is sleeping (screen off) nearly everything is powered down anyway, even if the data connection is 'on'. Apps will wake the device (an power up radios as required) to do their updates when they need to.

The whole idea of being able to turn your mobile data connection off is to disable mobile data completely. This is a very good option if you are roaming in a foreign country or don't have a fixed data plan.
If you leave the mobile data connection to enabled, applications will "turn-on" the data connection if needed (on-demand). In other words, if the mobile data connection is enabled, the mobile data connection will be in standby, waiting for applications to request use of the connection.
Hope this clarifies it for you, as you appeared to misunderstand my last post.
Ok then
I think it has different meaning compared to the Windows Mobile.
In the COMM MANAGER, there is "Data Connection" toggle which normally is OFF. And this does not mean that the device cannot use 3G data connection.
While on Android, its data connection toggle setting means to enable or disable 3G data connection completely.
I think that is the difference, if we look from Windows Mobile point of view.
Thanks.

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.
Hello,
1. I switch my Desire on (the smartphone heh!).
2. Everything works fine when I switch on the Network connection (Internet OK, syncing OK,...).
3. I switch the data connection off.
4. Later, if I want to switch the same connection on again, well it doesn't.
I hope I made myself understand.
Any idea?
Thank you!
If you switchit off/on with the Mobile Network widget sometimes it stays off/on.
Try deleting and then adding the widget back or switching on/off from the settings->wireless networks ..
Or, of course, rebooting the phone..
(sometimes the widget does'nt do what is supposed to do)
cheers !
Unfortunately, it isn't a widget problem!
In the settings, it says connection failed... (at the second attempt)
Of course, rebooting helps but it is a pain in the...
Thank you anyway!
Any other suggestions?
Delete the APN and then put it back.
And if you have APN's that you do not use, delete them.
Give it a try, maybe it helps.
While you are connected (via GSM) are you trying to connect to wiFi networks too?
Because I found a problem with connections.
When I:
1. I connect via GSM
2. then I connect to a wifi network
3. then if I leave he range of wifi my GSM connection does not work
The only solution is to switch of GSM module and turn it on again. To prevent this I always have to disconnect from wifi correctly.
I hope it's understandable.
Had the same issue, could only get it to reconnect after switching phone off and then back on, returned the phone, got a new one and now seems to be OK
Hi Guys,
Had my Desire a week now and loving it, but have a small by very frustrating problem. Sometimes and I have yet been able to reproduce this consistantly, the conneciton swaps to data from Wi-Fi while asleep, when I wake it up the phone works fine and uses the data connection but wont re-connect to the wireless.
In settings it list no avalable wireless networks, if I turn the wireless on and off it says its connecting to my network for a second and then gives up and says not in range, there are 5 other networks that should be in range and it list none of them. I have tried an app from the market that scans wireless and it has the same problem nothing is listed as seen. If I set airplane mode on and off the wireless jumps back into life lists all networks and connects back to mine. This has happened twice at home (uses WPA/PSK) and once at work (uses WEP).
As I said I cant reproduce this all the time and its fine to use the data connection but dont know why I have to airplane mode in order to get it back, do you guys think its a hardware or software problem am I rebooting the wireless hardware when I toggle airplane mode but not when I turn just wireless on/off? Should I try factory reset or send it back for repair? Has anyone else ever seen this?
Edit:- Sleep policy is Never.
Thanks for any advice.
Dan.
BTW- Stock T-Mobile ROM, not rooted.
Try a factory reset first and see how it goes from there
Hello guys, I have a problem here. It seems that whenever I use internet on my desire HD, my network does not automatically connect. I have to manually turn on the mobile network in settings. Do u guys have this problem or which anyone can help?
If I understand you correctly you need to check the box for "always-on" data. Go to: MENU->SETTINGS->WIRELESS & NETWORKS->MOBILE NETWORKS->ENABLE ALWAYS-ON MOBILE DATA.
If you already have that checked I'm not sure what else is causing your data to not be always on, or are you talking about your wi-fi connection?
For that follow path to wireless & networks, but then go to: WI-FI SETTINGS->MENU (soft key by home button)->ADVANCED->WI-FI SLEEP POLICY->(select)NEVER.
I had the same problem.
I had to get a new sim because my old one was 10 years old and wasn't fully compatible with my new phone. It re-sent out over 500 texts from my outbox.
I had to ring my service provider. They said my sim card had a old vault version
