gprs keep alive tweak - 8125, K-JAM, P4300, MDA Vario General

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?

Trinity data link and lost calls problems

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.

Surf and Talk Question?

I'm wondering if it's true that, we wizard user can't surf or transfer data and also have calls come in. Also cause this phone isn't 3g?
If so is there a tweak or program that will boot you off wifi or internet that you are doing, and have the call come in. I mean it's a phone no point have a phone if calls can't come in.
thanxs would like to know if anyone have an answer for this.

The fact that you cannot talk and surf at the same time has nothing to do with 3G. GSM/GPRS is capable of being able to talk on the phone and have a data connection. You have to have a GSM Class A device to do both at the same time. The Wizard is a Class B device. You can read more about this here http://www.gsmworld.com/technology/gprs/class.shtml Scroll down to the bottom.
If you are missing calls, it might have something to do with your provider. I have T-Mobile USA, and my phone is connected to GPRS/EDGE almost constantly. I don't miss calls. When you have an incoming call, your provider should suspend the data session to allow the voice call to come though.
Understood.
Thanxs d0ug for straighten all the question I had about it.

Setting Voice priority over Data

So I am using my N1 on att so therefor it only works on EDGE. The problem is that whenever I have an active data session open, my phone does not ring and calls just go to vmail. Is there any way to set the phone to take the call and suspend the data connection?
No one has an answer? Not even through rooting the phone can I get it to accept calls over data...
i haven't used my N1 on the ATT network, but i've never head of data overriding voice. on any network. Voice should kick your data connection. I wonder if you have an issue with an APN setting.
I'm looking for the same,
IM in the Netherlands on vodafone. 3g works fine, but can't call and use internet on the same time.
Dont you need to be on at least 3g to have voice and data at the same time?
this has always been my experience on quite a few phones I have had when in an EDGE only area and tethering on O2 in the UK, phone does not ring.
On 3G it does, in fact last night while on a conference call on speakerphone I decided to run the speed test app to see how much a voice connection impacted data and I got 300-400kbps and I normally get 1-2Mbps, only ran it once and forgot to run it again after the call has ended, so it could just be local conditions....
You are correct that you cannot have voice and data working at the same time unless you have 3g (HSDPA). If you only have and EDGE connection, you can use data or voice, not at the same time though.
So I called HTC directly and asked what the heck was going on and if there is a way to change this and they told me there was NOT. The device is set up to accept data over voice. So basically the sell it as an "unlocked" device but the functionality is is majorly flawed if it cant run on 3g. I am a little angry at this point, yes I should have researched a little more, but who the hell sells a cell PHONE where data overides voice

Apparently HTC does, probably based on usage stats. I use several gigabytes of data and 1500 text msgs per month on my plan b/w myself and my wife and we only use 200 - 400 minutes. I am pretty sure that we are not the exception either...

I understand what you are saying and I am the same way. But being such a heavy user I do often get calls when I am on the web. So it is crap that this device is really not a fully functioning phone on EDGE.
Asking your phone to put voice over data as priority on edge is like asking your phone company to put your mom's phone number over others and having her call kick someone else's call off while you are talking.
This is not an issue with the Nexus One, all phones, when on EDGE, behave this way. This is just the way EDGE works, this is why they push 3G devices and network services and not EDGE. It's old and not as functional.
If you are not happy with the Nexus One because of this, I would suggest selling it and waiting for AT&T to get their device that will compete with this.

That is not true. Blackberry curve for instance runs on edge, if a call comes it it will interupt the data connect to take the call. You cant do voice and data at the same time, i agree with that. I have had other devices like the G1 when it first came out and when it ran on edge and I was getting a call while on the internet it would suspend my data and take the call...
And I like the N1 that is why I still have it. It just sucks that on a PHONE, data is prioritized over voice. I was looking for a solution for this situation by either rooting or figuring something out within the phone, but I guess there is not a way to fix this.

You are mistaken. I've had at least 10 phones that ran edge for data and none of them could interrupt data for voice. You are probably using more data intensive Apps or webpages compared to the blackberry, so its more likely you are missing calls.
Go use the blackberry to download a 7 MB file and see if you can call it.
where i live i'm just outside the 3G areas
my past phones have been HTC and i just end up with a voicemail notification when someone calls and my phones were ALWAYS on data, people used to get pissed thinking i was avoiding them.
google voice fixes this, i can just switch to my notification, listen to voicemail or if i'm lucky read the transcription (usually doesnt match though ) without having to effect what i was doing.
On my winmo phones, if i tried to do this, i would sometimes go back to my browser to find it decided to close while i was on the call to listen to my voicemail and then i would lose what i was doing and have to start all over anyways. so this is just another reason i love the nexus one and google voice, you say useless data>voice, i say a fix to my problem. i love you n1! lol
I can not speak to blackberry phones but this behavior has been the norm for all of my smartphones, to include the G1. If I make heavy use of Edge in a non 3g area then phone calls would not get through. It is annoying but not a problem specific to the N1.

Mobile data used even when disabled in settings

Hi,
I have a Nexus 4 with latest KitKat and franco's kernel. I didn't update via OTA. I keep my mobile data disabled, but it seems that my phone randomly use mobile data. Data graph does not register it, but I can here the noise in my computer speakers, and my stupid mobile provider always sends me SMS when I start using mobile internet, so I know it's using it. So, any idea why this happens and how to stop it? Thanks.

Is it happening when your phone is slipping back into 2G - even if not being used the phone send paging signals to the network every so often - you'll hear it especially before a call or SMS comes in as the network sets up the call. Whilst technically it is transmitting small amounts of paging data it isn't charged to you.

Well, I keep it on 2g only, so that's not what is happening, and I mentioned that I get sms from provider when my mobile data is used. I just upgraded to 4.4.1, so I'll see if it still happens.
In meantime, if anyone has any idea why this might happen, please post.

Massively increased battery duration

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....
Any sugestions?
