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.

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.

[Q] Is there a way to disable data?

I just bought the Defy for my younger sister and was just wondering if there is a way to turn off the data since I only want her on wi-fi. I know there's apps out there like extended control but is there anything I can change in the settings? I did some searching but found nothing on the forum if I missed it can you guys point me the right direction? Thanks a bunch!

When in Europe I use an app called APNdroid from the market. It kills edge & 3G but leaves wifi and voice/text running. If you want to kill EVERYTHING but wifi, hit airplane mode then wifi.

I suppose it depends on your service provider, but if you set up nonsense information in your APN (i.e. it can't find a server) then it won't be able to access 3G data. I've set up 2 APNs on my phone, one to allow and one to turn it 'off'. Works like a charm.
Well, for me, anyhow.

+1 for APN renaming.

Go to market, find this--> APNdroid
Install it & put on desktop.
This will help stop the Defy from using GPRS.

Yeah I looked for that too but didn't find it so I'm just using the app. Thanks for all the help!

You can use the app"Droidwall",you can disable 2G,3G, and use only WIFI

You can try a battery saving app called "juicedefender".
The original function of it is turning off data when the screen is off, but you can use its widget to turn off data completely.

3G Location

Hi guys. Simple question here:
Always thought it was strange but never had the time to check if it was actually a Apple service only. Is it possible to obtain "My Location" through Google Maps app or Latitude, whatever, only with 3G on. I mean having Wi-fi and GPS disabled, wasn't it supposed to 3G be enough to obtain my phone's location?
Yesterday my brother who owns an Iphone4 did it and i thought "how come i never couldn't with my xperia arc"?
Is it any wrong configuration on my phone, or a google configuration or is it just a service xperia arc/xperia/android phones don't have?
Thanks.

Google Maps - works over GPS or 3G(HSDPA,EDGE)
Latitude also can work like one above..
But, if you have wirelles, and GPS disabled...accuracy will be around 300-500m.
while GPS accuracy is 2m

I always use Google maps with the data switch on. I usually have the GPS switch on also. Using just the mobile phone tower to use google maps doesn't accurately represent your true location, only the closest mobile phone tower the phone is receiving the signal from.
I have done this in the past, meaning using Google maps while using only the mobile phone network, since my phone at the time did not have built-in GPS.

Thanks, electrash, you are spot on!

No problem, try it and let me know.
P.s (sometimes it takes longer to get your location max 1-2min)

So meaning that something is wrong in my phone. I have it updated and non root. I have 3G (HSDPA) on and the phone is unable to obtain "My Location" and asking me to turn wireless or GPS on. What can i do to fix it?

but do you have 3G MB packet (pay for 200mb or etc) or you have flat internet on phone like me?

I have a 300mb per month subscription. Is there a difference here? The 3G or data connection isn't the same in both cases?

yes, but sometimes if you run out of MB Packet this wont work, i dont know why.
I have to go now, when im back i will find some app to test your phone (market seacrh)
Till then, have a nice day

Everything is working now. I needed to check in the location configuration the use of wireless and data connection to obtain position. LOL My bad! Thanks for all the help anyway! Cumps

Glade to hear that

Lumia 900 doesn't use wi-fi even though its active?

So,
I was downloading maps for Nokia Drive (entire US) and I was sitting on fully functional WI-FI. I was assuming it was downloading the maps over wi-fi because wi-fi was fully active on my device so i put it on the bed and started doing my computer business. But after a while I started to receive emails&sms from AT&T saying I'm almost over my data limit. I killed the download process and made sure it was on wi-fi. Started it again, and it was using my data to download again.
So, why the hell is it using my data connection to download maps? I didn't turn my data off, but isn't Nokia Drive supposed to download maps ONLY when on Wi-Fi?

That's odd. My L900 Wi-Fi always takes precedence. Only used 500MB on my Unlimited plan last month with Wi-Fi on most of the time.

Does anybody know if there is an app that can check if I'm using wi-fi as my phone tells me I am?

2 Things to think about here...
1) I've noticed that my Lumia 900 still sometimes downloads off the cell net even if Wi-Fi is active and working. I think this is a bug.
2) If you phone goes in to standby mode, Wi-Fi will turn off, and it'll start downloading over cell network. I've had this happen with downloading games off the marketplace that start over wifi, but then stop, and resume over the cell network when the screen/phone goes in to standby mode.

Contacted Nokia, they said that if wifi is unstable (meaning disconnects even once for a minute), it will automatically switch to data to download maps. Wish I knew that before.. 3GB gone in an hour.
Future downloaders, take note. If you want to download maps without data, make sure you switch your data off before downloading.

Bandwidth will tell you while running a speedtest if you are on WiFi, 4G, LTE, etc. But you can only sideload this app now as it was removed from Marketplace. Not sure if the other speedtest apps also provide that info.
I have noticed at least one app, Fox News, that only appears to like a data connection. So if I turn data off for a couple hours, but leave WiFi on, and even if I am almost constantly using the phone, the Background agent will be disabled within a hour or two. I suspect other apps may have some coding that could cause this kind of problem.

I just got one of these for my wife. Being an Android guy, I am lost at how some things work on this phone. I see here it's mentioned to turn data off.... How?

It's in Settings --> Cellular.

Yup just saw that in the manual duh

WP7 by design will turn off wi-fi whenever phone goes into sleep (you can easily verify this by wake up your phone and check the wi-fi icon on status bar. It will start beaming up because wi-fi is connecting). However, you can change this behavior by keep the phone plugged into the charger.
Because of this, anytime you want to do any kind of big download, swipe down your status bar and verify your wi-fi icon is active and steady. You don't need an app to tell that.
Remember, just because you have wi-fi turned on doesn't mean your phone is using it all the time.

GPS works under certain circumstances

Hi guys. I'm sure this has been asked over and over, but I didn't find something that would be helpful in my case. The problem is simple. GPS won't fix on to my location without a data connection. I have saved a map offline (in Google Maps), and whenever I'm travelling and want to see my location, I turn the GPS on (mobile data and wi-fi is off) and press the location button in Google Maps. In a couple of seconds, I get the message "Your location could not be determined".
Turning on mobile data helps, it locks in about 15-20 seconds. But switching from Google Maps to some other app and back causes it to forget the lock and it has to search for my location again. Once again, it takes around 20 seconds.
On Wi-Fi (and no mobile data turned on), although it shows 'Searching for GPS' in the notification bar and the GPS icon shows that it isn't locked, it estimates my location correctly.
I've tried running GPS Status, downloaded AGPS data using the app, still no use (I expected this to work, since i guess the problem is about obtaining AGPS data, that is why it locks quickly when either mobile data or wifi is on). I don't get a lock while running GPS Status, nor do I see any satellites in the app, regardless of whether Wi-Fi or mobile data is on or off.
In short, I just want to be able to use GPS in Google Maps without anything else- without Mobile Data, without Wi-Fi
Hope that's clear. Thanks in advance

What baseband are you running? You might wanna try FH05.

I also have this problem,use u-center which will get a GPS lock then open maps,you should get a GPS lock within seconds,not sure if the baseband version will make a difference.
