Q: Push Email and Data Charges

Just curious? If I have Push Email set to ON. My device will connect to GPRS/3G then download my emails right? Now after it is done downloading I noticed the connection is not closed. At this 'connected but not active' state is data being used/exchange between my provider and my device? When a device powers down to standby is this connection terminated [and therefore billing should stop, right?] or is the device still connected to the data service? I'm asking because we don't have use all you want data plans here in Manila. My 1st provider SMART charges PhP 10.00/30 mins and the 2nd Globe uses PhP 0.13/1Kb of data. So I am thinking which provider to use for Push Email... at the moment it seems that Globe should be used for Push and Smart for surfing, am I reading the situation correctly? Any expert knowledge on Data and how it interacts with our devices will be greatly appreciated.

Auto disconnect of GPRS after email check

Hello,
I just found and test on my vox, the way to autodisconnect from GPRS after the mail check. I was very unhappy with this feature because my battery was drained much faster then now.
The way to autodisconnect is:
Edit registry with a registry editor:
go to HKLM\Comm\ConnMgr\Planner\Settings\
Create a new DWORD value: CacheTime with decimal value of 60
This is the amount of time in seconds your smartphone will wait before ending the packet data connection.
Under SuspendResume, remove the string "~GPRS!" and replace it with "GPRS_bye_if_device_off"
This change tells the device to obey the time set in CacheTime and sever connection, vice the default setting of leaving the connection all the time.
I tested that settings on HTC S710 and Samsung i600 and it worked.

thanks for the great tip
Thanks a lot for the tip. Has been looking for it for a long time. Because my previous handset (Nokia E50) used to automatically disconnect after checking mails. Looks like Microsoft gets a cut money from operationrs for GPRS usage

hi,
this method will only cut gprs connection after mail sync or all connections ?
60 second after the end of sync or after the start of it ?
a lot of question ;-)

Click to expand...
Click to collapse
this setting will close all GPRS connections immediately after they are not used.

Don't work! (Samsung Omnia i900)

Also when you might have been busy browsing the internet or using a chat application for instance Mxit, and someone calls you the GPRS Connection gets dropped but it does not continue after the call has ended.
I did some testing on my own and made a thread about it, but still haven't got an answer to my question except for not changing the registry and leaving it on default, the session will continue after the call has ended and using the Com Manager to end the connection manually when you are done.

[Q] E-mail + WiFi + Data

Hi, I'm using Energy rom 21914.Sense2.5.Cookie.GTX.Aug.24 in my sprint TP2 since the release and today I'm experiencing a problem:
when connected by WiFi (with max strenght signal also) and trying to send or sync my e-mail, the phone will open a data connection instead of using the wireless one already connected!
The problem is that I have a very very limited data plan and since I'm usually connected by wifi this sucks...
The other apps, weather/opera/etc keep on the wifi connection and the only thing that opens a new data connection is the mail - by the mail tab and by windows live.
I also know that I could turn off the data connections with "Data Controller" or so, but I'm really upset because all was going well until today and now with no apparent reason it occurs this stupid thing!!
Anyone experiencing this or having a solution to get it back to normal?

Can I turn off data plan access on AT&T Smart Phone?

So I've had this HTC S743 for about 5 days and I thought I had it setup correctly to use wifi for data comm.
wifi enabled and selected to use my home network. I can see the radio tower status icon and my locally named network is also displayed.
Under the comm manager the data connection is off.
I have a very simple $45/mo plan with no monthly data plan.
Over the last 5 days I have been surfing the web a bit did some email tests with my ISP and used the on board GPS app which is horrible. Not heavy usage but experimentation to see if I like how the phone works.
After 2 days I get an email from AT&T that I have extremely high data usage exceeding my account limit (for having no monthly plan) and that I should sign up for a data plan at once.
$29 over 2 days for this little bit of fluff? A total of 2,900kb in data.
So I call up AT&T and they tell me this and that and want me to sign up for a plan which I may do. But I want to be able to know that the datacomm is happening via WIFI when I can see a selected WIFI is in service.
They also told me that all GPS data is forced through 3G and bypasses WIFI???
Can anyone here give me an idea about what I may be doing wrong and whether AT&T is correct about the GPS service?
Is there a better GPS app that doesn't do this? This one pretty much stinks anyway. A resolution of 1000 meters doesn't cut it.
AT&T also informed me that I can't have a smart phone without a data contract. Really? I've had one for 6 years like that but it wasn't WIFI capabale and too small to bother with web access.
Thanks for any light you shed on the subject.
One thing I have subsequently found out is that if data connection is off and WIFI is off then when I go into IE and start surfing it does bring up pages. Then when I go back to the Comm Manager the Data Connection to check the status of my connections it is still off for an instant and then it automatically turns itself on as though it had been turned on by use of IE and the status was just being updated.
Last night I installed a newer version of Google maps and was only able to install it via the web browser as opposed to via the Activesynch application on my PC. I was concerned that this might trigger turning on the 3G connection. So I had it set up for a WIFI connection ONLY and installed the app. Afterwards I went into the connection manager and once again the data conn. was turned back on so it's possible that it utilized AT&T's 3G network instead.
Is there any way to control or stop this?

GPS data doesn't have anything to do with 3G/Wifi data......

I know it's supposed to be positioning via the satellites through the GPS antenna but the the description data is coming over the network right? So it appears that even though I'm setup for WIFI access and it's showing as connected with an IP address etc. when I try the Googlemaps GPS app it turns the data conn. for 3G back on.
Thanks for chiming in ...
I have been copying over and installing some new apps to try out this morning via usb. WIFI is on and I'm loged in. None are datacomm oriented that I know of (unless they'r trying to make an internet access to notify about being installed) none the less I just checked again and my data conn. is once again turned back on. Is this typical behavior for a windows mobile phone (6.1) or is this just an AT&T "feature".

Sorry, I don't have a WM6 phone!

Can apps bypass disabled Data Transmission?

Is it possible for applications to bypass Data Transmission switch and Roaming block?
I have been traveling abroad recently and even though I have Roaming Data disabled and Data Transmission disabled in the system I still got charged for data transmission.
I have travelled with it before last two trips and have not seen the problem.
Since I had similar situation last time I was traveling, I made sure that those settings are off couple of times over the course of the trip.
When I check data usage (Settings -> Data Usage) for that period is practically zero, but there are some Google apps listed for that period: Internet, Kids Mode, Youtube, Smart Remote, and Google Movies BUT they all list 0kB for usage and I'm not using neither KidsMode nor Smart Remote.
It does not look like operator related since I got charges from several countries.
Any ideas what might be going on? I will file a complaint for the charges with my operator (not counting on positive response there), but I still would like to use my phone when travelling, but if blocking data transmission is not enough to prevent roaming charges - what is?
For reference my phone is European Galaxy S5, running Stock, not rooted, 4.4.2 Android
thanks in advance,
Kubak

Data off from settings will surely off any transmission. No app is allowed to bypass that setting. Dont know if you are talking about check on data roaming, you should just off the data.

There could some problem with the data switching. Since your phone is not rooted it shoudn't happen but some apps may be doing this. Try flight mode/airplane mode. If problem still does not go OR if you want your data on Try the app permission management.
Settings-->Security-->App permission management.

Thanks for the replies guys!
To clarify - I have been always using the Roaming data off setting when traveling. And it worked until my last two trips.
On previous one I did not disable data since the setting always worked before. When I got charged for data, I made sure I additionally switch off the Data and keep it off during my trip.
The data usage meter on the phone shows 0.0 kB with several Google apps listed (as mentioned initially) they are all set to restricted mode - no background data.
It looks that IF there was any transmission it was small - one of the operators on route charged just 1kB, but ATT was happy to charge me 50kB up and down every time this happened?
The Airplane mode can be a solution but will pretty much "kill" the phone - I would still like to be able to be reachable under that number.
I was a bit suspicious of Llama app fiddling with data, but even that should not bypass the Roaming setting (and there would be a lot of data being transferred)
And the problematic part is I don't think I can check data usage with my operator in real time - I just learn from my monthly bill...
So it looks like "something" is bypassing the "no data in roaming setting" - but what?
Any suggestions are welcome

I had the same experience recently and I've figured it out. Even if your roaming function is turned off there are VOIP apps that can bypass your roaming and you will get charged for data. Facebook calls, Whatsapp calls and IMO calls are a few. I noticed the last time when I was travelling through the States (with my roaming off) that when a fb call rang my phone (I did not answer), every frickin' fb notification for the week came through during the duration of the ringing (remember ... I did not answer / connect to call), and I got dinged for 4 bucks for every one. The only way to get around it is to have phone on airplane mode or delete / uninstall the apps while you are away.
