My transfers suddenly went up to 1 GB/month. It was below 200 MB normally.
I compared my GPRS data transfer list with the speaking details and it turned out that some times GPRS got connected while I was talking on the phone.
Is this possible?
I really don't want to pay for a billing mismatch of my carrier... and it's a loooot of money, I tell ya!
"If I am connected to the Internet (e.g. via GPRS ), can I still receive calls?
If you are Sending or Receiving Data via GPRS at the moment the voice call arrives, you will not receive the voice call. Otherwise your phone will ring and you will have the choice to Answer or Ignore the voice call. If you answer the voice call the GPRS data session will be suspended. In the future, some GSM networks may deploy functionality which allows incoming voice notifications to be received during the sending or receiving of the GPRS data. Answering the voice call will suspend the transfer of data."

Is this true, is this half-true, it depends, or please somebody explain it to me!
Thanks in advance
You get either data connection or voice. If the Wizard had a 3G radio, then you could have both as long as 3G was available where you were.
Yeppeee! That's what I supposed to hear!
Now I can deny to pay those false bills.
Thank you very much!
I'm not sure if your provider will accept my comment as expert testimony!
That's just for me to be sure about my truth
They said I must ask HTC an authentication of that my phone is unable to do that. Then they revoke their bills.
Thanks again!

Hi folks:
I cannot be totally sure if this is the cause of this, but after loading the v1.2 ROM, I am missing calls while I am transferring data on GPRS. The weird thing is that while GPRS is on and I am not transferring data, I get calls in, but if I am browsing on sending/receiving email, I miss the calls.
Can this be related to the ROM update, or is it that I have a setting that needs to be adjusted ?
Any help will be greatly appreciated. Thanks,
Fernando
What did you have before the 1.2? We did not change much in the way GPRS connections are handled relative to 1.1.
Hello:
I had the current T-Mobile ROM before upgrading it to ver 1.2. I like this ROM a lot, but I noticed this little snag that makes me miss calls every so often.
Thanks in advance,
Fernando
This is exactly how it has ALWYAYS worked. The XDA uses a subset of the GSM spec which does not allow for simultaneous voice/data, and you cannot receive a call while ACTIVELY passing data. With the connection open but not actually sending data, the phone will ring. If you answer, there is a delay while GPRS is dropped and the call is picked up.
There is a spec for simultaneous voice/data, and also a spec for getting calls and suspending GPRS temporarily (leaving your internet connection just where you left it once you hang up the voice call). The XDA supports neither, and actually most carriers are not able to support simultaneous yet either (at least the US carriers cannot). They do support suspend, which works with phones like the T68.
Hola Carlos:
This makes sense, and it is actually the way it is happening for me. It seems I only noticed it now. I actually notice the delay in answering the incoming calls while GPRS is dropped.
Thanks for your wisdom and help.
Cheers,
Fernando
Hello Everyone,
I am having a wierd issue with my HTC Tytn.When my Data connection is active I cannot make or recieve phone calls.Any incoming call goes straight to voicemail and any number I dial the phone will display "call ended" before it even starts to to ring. The minute I close the data connection the phone works again.I have updated my ROM to the latest English ROM.Could my unit be defective?
Thanks in advance!!!
Hmmm that's weird.
Your TyTN is acting as class C device (Data or Voice), and in fact TyTN is class B device (Data is suspended while on Voice).
Is your unit defective? Possible, but... first backup your TyTN completely, then re-update full ROM, set up data connection and call to check it while on active transfer. If it will be OK - your unit is OK and this is software/registry problem, if not your unit is might be defective. This is the quickest way to determine.
My device does this as well, but only when connected to Slingmobile.
Other "always on" programs are not affecting me.
Not sure if this helps or not Just trying to add more data.
data causing call dropouts
Hi,
Hope this helps, but here in Australia when using the Telstra HSDPA network on UMTS850, when i'm connected to a data session, I can't receive calls and the caller gets the "phone is switched off" message. If I force the phone to use the old UMTS2100 network, the phone will pause the data session and allow the incoming call. On another forum I have read that this is due to a limitation in the Ericsson 850MHz hardware which the telco is using on their mobile towers and they expect an upgrade to fix it sometime in January. I don't know if this is 100% true, but it is what i have read
If I have a data session in progress it gets disconnected whilst a phone call is in progress (I can receive calls fine, although I have had one or two occasions when people have rung me and it's gone straight to voicemail without notifying me of the call). After I hang up, the data session is reestablished.
Using T-Mobile in the UK for what it's worth.
This is a very weird issue, sorry I can't offer any more info or advice.
I'm on T-mob Flext WnW and have the same issue. When I have my data connection established (either gprs or HSDPA) anyone that tries to call goes straight to voice mail. I can make a call which temporarily stops the data session and then re-establishes it after I hang up.
Is this a known issue on T-mob?
In the HTC faq, it is meantioned that the handset is a GPRS class B device:
http://www.europe.htc.com/support/faq.html?id=119
This means that the data-traffic is suspend for voice calls.
http://www.gsmworld.com/technology/gprs/class.shtml
(I haven't tested this with my HTC, but my Nokia 6260 did behave like this)
The HTC faq also states the full 3G operation ought to allow for simultaneous voice and data calls. I personally interpret this that calls are possible together with a UMTS connection (but I could be wrong).

For all with problems with connection while on data.
Most of us here have no problem with it, might be network you are logged, not fully compatible with class B.
My advice: check different phone (TyTN) if same occures, if yes then different handset (other brands). If it still is happening - call network and demand some explanations and upgades.
Still supporting my first post to hard reset device and check if without all software you have same problem.
And for the record - most of mobile operators calls this "Ring-through problem"
JUST FYI
Cingular says that for some reaosn streaming data (for my my slingbox) will not interupt. So phone always goes to voicemail.
Once I get the higherspeed data in my area this problem should go away.
This was posted by another in response to my question, and also confirmed when I called Cingular. Although it is possible we were both misinformed by support.
I'm sure I've read about this problem in the past but I can't figure out whether there is a way around it. My model is an MDA Vario II in the UK. Is there any way to avoid missing calls when the phone is connected to the internet?
It's great having a phone with internet access, but not so great that it doesn't seem capable of functioning as a phone at the same time!
thanks
Can anyone help with this please?
thanks.
Am I really the only person with this problem, or am I just being really dumb with my forum searches?
thanks
I think there is a difference between GPRS and UMTS. When a GPRS connection is active (at least, when data is sent or received) you are not able to receive calls. When UMTS is active, calls should get through. The standard way should be that the device detects an incoming call, shuts down the GPRS connection and restarts it after the call is ended. With UMTS, the device can receive and send data and answer the call at the same time. I have actually never had any problems with unanswered calls while browsing, but I use UMTS all the time (or perhaps no-one is calling me while browsing).
I have no idea what fault in your phone could cause your problem. Try searching with better keywords perhaps in the future, I found several threads relating to this problem by using the words "data connection missed calls". Use the same words for a search and I am sure you'll find lots of threads about this.
This will always happen with any handset. if you are sat there reading a page and not loading any data then the call will interupt the GPRS connection then reconnect once the call has finished. If you are sending or receiving data then the person will get a busy tone. Sorry this is just how all the UK networks work.
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.
Hi I have just asked my provider to help make my tab work as a "phone" and was told I couldn't unless I enabled VOIP for $10 P/M
I'm not too happy about this and told them so!!!
They have come to an arrangement with me but I'm still not happy because It still sounds like VOIP to me and over 3g it drops out.
Is there a way to prove this traffic is actually data/voip
my interface shows up as SVNET0 I can capture the the UDP protocol by using OSMonitor but I don't think that is detailed enough.....
cheers for any help
PS I am running stock FROYO
First off. Who is your carrier? If you're in the US no carrier will give you voice service only data. In order to enable voice for a Tab in the US you will need to root it and then do some homework by searching through XDA. In other countries that do allow voice and data on the Tab, your mobile plan should be like any other smart phone.
cheers
Well first off I'm with Optus, and the girl tried to offer me an add on voip service to allow phone calls.
anyhow I was watching my data interfaces and sure enough they do move while on a "Voice/3g" call so although all digital transmissions could be data, these ones are UDP in particular which points to VOIP...
just need more details.....
cheers anyways
