I've seen this registry tweak and I was wondering how often it sends out data to keep the connection alive? I just don't want to miss calls cause apparently you miss calls when data is being transferred, which is real stupid, how can a sidekick which is a childs phone be class "whatever" to be able to switch back and forth between voice and data but a grown up phone like the mda cannot.
You won't miss calls
Being connected to GPRS doesn't interfere with the phone, just downloading data interferes with the phone. The same was true of the Treo 600, I don't know about later ones. Keeping GPRS on all the time, you use about 500B of data per hour, so it is barely connected.

speaking of which, is there a fix for that? I read that it's only t-mobile that refuses to connect you when you're transferring data. will a custom rom fix this issue?

The Wizard will receive a call even in the middle of data transfer with out a problem.
Also, the registry tweak doesn't send out any data. It simply changes the phone's behavior to not automatically disconnect from GPRS/EDGE after X amount of minutes.
Data use
According to SPB GPRS Monitor, there is data use. With the registry tweak, I use about 500B per hour average. This is with no programs running and is probably no more than a "are you there?" "yes" every so often.
cool thanks for the replies guys, I set it to always on.
and gldrush I've tested it a few times, I do not receive calls when data is being transferred.
p.s. anyone know if this shortens battery life? any other long term affects?

Wrong. It goes straight to voicemail
Hi all
I am wondering about the purchase of a Trinity. Someone, on an italian forum, has posted the problem of incoming calls lost (the caller receives a busy line signal or the phone results unreachable) while the phone has a data connection active (apparently only an HSDPA one). Has any one observed a similar problem ?
Thank you everyone.

This is standard behaviour when transferring data over 2G GPRS. It should not happen on 3G. I have received phone calls while using 3G data and the phone rang as normal.... I can't report about HSDPA (is there a simple way to check if HSDPA is actually used?)

No, it's not, voice calls always have higher priority even in 2G networks.
Can someone else confirm this issue with Trinity?

Well.... it's the third time in a few days in this forum that I post something and I am told that I am wrong. The previous two times in the end I happened to be right, so according to statistics I should indeed be wrong this time!
However I think I might be right this time too! The standard behaviour with GPRS sessions is that they are interrupted when they are idle and an incoming call is received; if data is being transferred then the phone will be busy.
Obviously for outgoing calls the phone will stop the data session when you want to make a call.
(All this for GPRS on GSM)
PS: You don't believe me try to use a GSM phone as GPRS modem for a PC, start a large file transfer and try to receive a call.

Well, since I use GPRS internet for more than 3 years actively and have changed a couple of phones already I must say that GPRS system is projected in a way that voice calls are priority in any situation. In this years I have found that sometimes my phone is not reachable when I'm connected to a GPRS but that percentage is rather small, could be some other problems related to a base stations.
In your case I would think of contacting your operator, change phone or just change a carrier, being unreachable during GPRS sessions is something that I will characterized as bug, at least. NHF

You are right. It was a very common bug in the early Class B GPRS phones and I thought it was supposed to be like that, but indeed even a class B device should suspend the data session and ring when a call is received.
However I am reading in other forums that this is now happening again with HSDPA.... the joy of early adoption

I had some strange behavior like a busy signal when I had my phone set to 3G only, but I think it was because of marginal reception. I changed the frequencies to automatic and haven't had any problems since.

Hello hawk971,
I have the exact same experience while being persistently connected on the Swedish HSDPA network (Hi3G) I cannot receive or even make calls, most of the time. It's like i can sometimes manage to "slip through" with a call, and even an incoming call can get through if i'm lucky. I have figured out that if i end the data connection and make the call, i can re-login with the connection and keep babbling on the phone.
The problem started to appear right after we moved to a different area where HSDPA is deployed, at first the problem was very sproadic, but now the network is growing, so does the blocked calls.
Luckily i get an sms from the 3 network saying that someone has tried to call without leaving a message, otherwise i'd be clueless.
I have considered contacting 3 operator to discuss this, but i reckon i might loose the HSDPA access then because i have only 3G subscription but somehow my phone (which is purchased without operator lock and not from 3) snaps right onto the HSDPA access nevertheless. I have a consistent 1Mbits/s DOWNLINK and 350kbits/s UPLINK connection while running TPTEST on the laptop and using the P3600 with internet sharing and USB-cable.
I so would like to be able to stay on the HSDPA but right now i am considering to drop the high-speed since the phone part is basically rendered useless. I am also using GpsGate in the car, so my internet is always on, transmitting position, i guess that makes the problem worse. I might have to drop that...
I had a friend told me he had the same problem with TyTn and Hi3G here in Gothenburg. That makes me think that there's no particular problem with my phone. Rather it's a network problem that they yet have to solve.
Anyway, that's a long post!
P.S. Does anyone know how i can disable/enable HSDPA on the P3600 easily?
Cheerio
just remove link to "enableHSDPA.exe" in \windows\startup folder and soft reset you phone.
I can't find this file (enableHSDPA.exe) anywhere in my P3600....
Bump!
SecureGSM can you please elaborate a bit on this .exe file. I have a standard HTC P3600 and I don't see this file anywhere in the file system.
i'd like to know how i enable HSDPA on my HTC P3600. has anyone had success doing so?

I recently installed the fit4can or HTweakC as it is now called from here
http://wiki.xda-developers.com/index.php?pagename=Hermes_Registry. It allows you to turn off HSDPA and do other tweaks to your Trinity. No harm is done since you can turn the HSDPA back on again anytime. Since I upgraded to the new 1.38 Radio, I was picking up HSDPA all the time at home, and every time my phone was auto checking email I'd miss calls. This HSDPA "feature" needs a little work.
I can usually browse the web and use data while I'm on a phone call.
Tonight I tried it and had no data connection until disconnecting the voice call. Can anyone who has not installed the OTA verify that it is still working? Or anyone with the OTA? Maybe I'm just crazy and am remembering something that didn't happen? No, I'm sure I could do both before.
I would hate to lose it this feature.

Works for me.. I've heard people say this happend before the update too, but I've never had any issues with it. Best thing to do is call tmobile to help you. It might have something to do with a weak signal, or not enough signal to handle both at the same time.
Have you tried using wifi calling and then browse the web through your wifi? That would prove it was somehow related to network signal.

My net won't work on Edge during a call, and is kind of laggy on 3G.
Sent from my T-Mobile G(dos)
U can only use data and voice with 3g/4g.
Edge uses the same stream as voice so you cant do both on edga data.
But I always use data and voice, mainly when looking up addresses or phone numbers
Sent from my T-Mobile G2 using XDA App
So maybe it was because I was on an Edge only network at the time of the phone call? I'll have to experiment more. To tell the truth I hardly make any phone calls with my cell phone.
This was all during a 35 minute trip across town so it's hard to believe it's on Edge the entire time since I have really good H access around town.
I'll call T-Mobile soon if it doesn't fix itself.
I've also been using a SIM that came with my Sidekick which was two phones ago. Going to also ask them if I am on the best web plan.
Thanks for the help.

I have noticed this problem on my HD2 for a while now. I am sitting on a nice 3G signal and the moment a voice call connects, my data connection dies. it does eventually drop to Edge or GPRS but bounces back the instant I'm off my call. it's really consistent as in the moment I connect, it goes.
I've seen this behavior on both my Windows and Android builds on my HD2.
I'm starting to think this is either a hardware issue or perhaps a greater T-Mobile one.
Any thoughts?

it usally takes about 30 sec for me to recover data on my phone sometime on 3g even on my tp2
I'm pretty sure now it was because I was on Edge. I've been able to use web while talking just fine recently.
I'm guessing a lot of people on here know this already but I recently discovered how to massively increase my Moto X's battery duration. Namely by switching off Mobile Data, I can then go a full 14 hours only dropping down to around 75% by the end. So now as soon as I get into work or any place where I'm on Wifi I switch off mobile data.
Makes me wonder why having mobile data switched on is expending so much battery power?
If you wanna increase that even further, just turn the whole thing off. The battery will last for weeks.

It is not shocking but somehow people tend to forget the basics. And it is also unnecessary while on wifi, which is the case and the advice he spoke of.
And I'd go even further and set 3G only with wifi, lollipop tends to switch from wifi to LTE by itself very often.
I've heard of people suggesting switching off wifi when your not using it, but never mobile data. So i just thought it might be a suggestion some people might appreciate. Take it or leave it.
Plus wifi is doing the exact same funtion as mobile data when your connected to it, so your not losing any functionality.
If your rooted you can even get Tasker to do the switch automatically.
This actually doesn't work. The data radio goes I to sleep mode when WiFi is on. Its not just doing its own thing while wood is on.
Definitely working on WiFi enhances battery life enormously but didn't try switching off mobile data

How is this possible? When your wifi radio is connected, the data side is completely disconnected. This is even reported in your 'status'.
I see your point, but all I know is that it definitely is making a large difference for me.
One theory I attributed it with was that with Wifi and Mobile Data switched on the phone is getting a lot more Wake Locks (perhaps doubling up), which in turn could also possibly be preventing the phone going into a Deep Sleep. But as the Wakelock detector app doesn't work any more (unless your rooted), I can't verify this.
Gonna test this out!
The issue with turning off mobile data is that it will cause problems with sending and receiving MMS, you may also have problems with SMS as well.
My HTC Sensation was really good at basically putting the radio to sleep when on Wifi and only waking when needing to send or receive data that will only work over the cell network.

I don't disable mobile data, but I do use tasker to switch to 3G when I'm connected to wifi. The LTE radio uses a lot more battery in poor signal areas (like my apartment) and I have noticed it helps me go from about 3 hours of screen time to 4.5. I think the MMS issues are a good point and I feel like this solution is slightly more elegant because even with mobile data disabled, the phone is still holding an LTE signal. Ymmv, obviously

First you'll need root and this plugin (make sure to enable external access in the plugin app)
Basically, create a profile that runs whenever you connect to a network (you can leave it blank for all networks or press the search button to choose just your home network).
The entry task would basically wait 10 seconds and then run the plugin choosing wcdma/gsm (auto) as the network mode. Choose then to add an exit task which simply recalls the plugin and chooses the network mode as LTE, wcdma, gsm. You can even add an extra step to each task at the end which has tasker display a toast that you can have say LTE enabled or 3g mode only

SMS is sent over Voice channels. MMS still requires data.
I double checked and tested this on my Pure Edition on T-Mobile.
Disabled Wifi and Cellular Data
Sent a standard text message, it was received by the other party. Attempted to send a photo message, it was not able to send from my phone as well as the other party did not receive it. Though it did resend when data was enabled.
Tasker can't turn off mobile data since Lollipop update....

Troll alert
So when I first got my V20 (VS996), when wifi was connected the mobile data went inactive- at least I'm presuming so, the '4G' was grayed out, not crossed out, and when there's simply no 4G signal it entirely disappears (or drops to 3G etc). But now it ALMOST never does this anymore... every once in a while it will, but there's nothing specific about times it does.
I'm pretty sure that's what it's supposed to be doing, as there's even an option 'Cellular data always active - Always keep mobile data active, even when Wi-Fi is active [...]' (not enabled). I've searched high and low for a setting that could be causing it not to work right, and information about this, but have come up dry. Is anyone familiar with this? Really didn't want to have to reset and track it that way.
Thanks.

I'm trying to get it to turn mobile data off, not hand off to it even easier. Are you saying that these options will make it disable mobile data when wifi is good, when it's not even doing that without them? Tried that just in case, it's still not deactivating mobile data (still at my desk, wifi router for 100mbps symmetric fiber showing full strength 2' away, so unlikely bad signal)
Edit: I may have found the issue. It appears one of the Verizon apps was forcing the cell connection to stay alive. I tried killing a bunch of the ones I wasn't using after recalling how their voicemail app only runs over cellular, and now mobile data is deactivated. I'll need more trial and error to confirm which one was doing it.. I killed 4 of them.. and it stayed off after re-launch so was clearly some kind of bug. Although it's odd as it did persist through reboots.
Edit: Confirmed; it's the 'Caller Name ID' app. Ending that single process restores the normal mobile data deactivation when wi-fi is good.
So another cause of this problem has popped up. After a reboot, 4G was becoming active after 15-30 minutes despite not touching the phone at all since the reboot, and there were no apps that could be killed to get it to switch off this time. But after a lot of trial and error, the cause was finally isolated: The My Verizon data meter widget. Once it refreshes, it forces cellular data to stay on, even when Wi-Fi is connected and strong. Once the widget was removed from the home screen, 4G never came back on while using WiFi.
Is there any way to disallow an app from using 4G but still allow it to use WiFi? I really would like a better solution than just not being able to use the widget. It would be fine if it just connected, got its update, then disconnected... but no, it's on permanently after a refresh.
