Whenever my friend is connected to net on a laptop using a WM6.1 machine with Internet sharing on a USB link and GPRS/Edge Internet connection she gets a Voicemail reply to any callers? Is this a problem with the phone or GSM provider.
It´s a network thing. Some providers set higher priorities to voice calls, so an active GPRS data connection is interrupted, others (like the one I have) unfortunately send incoming calls to voicemail and hold the data connection active.
Thought as much, thanks for the heads up.

I'm sorry to put this question here, but I searched the forum, found nothing, placed my question over at the network/connectivity forum and got just one (not realy satisfying) reply...
I think this is the most active forum on xda-developers, so at least someone should have an answer to my question:
is it possible to have an active network connection (with WM6 on the Hermes, or using the hermes as a modem) and place/receive phonecalls at the same time?
I don't use 3G at this moment, but am planning on using it.
But I need my phone to be able to place/receive calls while having an active internet connection.
has anyone any info for me about this?
thanks
If you have 3G yes you can. I often use my laptop with my 8525 as it's modem to Remote Desktop into a file server while talking to the client with my BT Jawbone.
But... if you don't have 3G in your area you're limited to a single channel for voice and data.
Internet Connection and voice calls
I have tested and only is possible if you use a simple 3G connection, if you use a HSPDA connection (internet at 1,8MB if avaliable by your provider) you don't recibe or make any call, all the calls that you recive go automatically to your voicemail. I don't know if is a problem with my provider or if is a any limitation of the software/hardware.
I have a SPV M3100 with Schap's 3.54b PTG ROM, 1.50.00.00 radio and 32.83.7020.20w protocol
in my case is strictly a case of what radio version I use.
on radio 1.50 I could not receive calls both while GSM or HSPA data connection was active.
on radio 1.40.30 i can do that and on the newest 1.51 I am still testing...
my network vodafone RO.
Hello again a have flash the new radio version 1.51.00.10 and have activate the HSPDA on my Herms (by default I have the HSPDA deactivated because I have a Direct Push Mail activated and if a have the HSPDA ativated I never recive a call) and I try to make a call and recive but nothing, I don't revice and I can't make any call
I am using HTC desire (T-mobile UK) for past 28 days. Most of the time my friends tell me that they are not able to reach me. They get the message something like not reachable.
I did not know what was the problem initially. But finally I found that the issue was when I browse internet. At my office I only get '2G' signal inside the office building. The problem is when I am browsing internet in my office (using the available 2G signal) then I cannot receive any voice calls. Who ever try to call me while I am browins in 2G will get a message "*** The mobile number you have called is currently unavailable please call again later ***"
This problem does not accur when I browse internet in '3G' or 'H'.
Is this the issue with T-mobile network or with the HTC desire phone.. please help.. Thank you
my phone is in wcmda only mode, so i would not know about that problem mate... I will try it out on gsm only and see what occurs

Looks like you've just been given an answer over on the t mobile forum. Quoted from 'Chippy':
This is a limitation of GSM/GPRS. If you have a PDP context (GPRS conection) but *no* activity is occuring i.e. no data transferred at that specific time, then someone should be able to ring you and the connection will just be suspended while they do. However, if the GPRS connection is active at the time then the channels needed by the the network to page the mobile are in use and the person calling will get an engaged tone. This a perfectly normal limitation of a 2G network and not a fault of either the phone or the carrier. Do you not have W-FI at work you could use?
Try putting your phone into WCMDA mode only and see if you keep a good enough reception to warrant its use
Tmobile is set up to reject calls when the GPRS is active. You will only get a call when on 3G on tmobile. Vodafone is the only operator in the UK that drops data to take the call on GPRS.
I never knew that. Now all those missed calls on t-mobile makes sense now. where I work has poor 3G service and I guess with so much syncing now there is more chance of a connection being active when a call comes in.

I am facing a problem related to 3G data connection.
The problem is as follow, while having a talk (voice) many times the data connection (3G/H) drops due to some reasons and never re-established until phone call is over.
I found this to be very annoying, if no phone call been done the data connection is perfect 99% of the time but doing voice call disconnect the data (both 3G/H) and never re-established until the phone call is over.
Once the call is over, the data connection resumed (3G/H indicators shown)
Please advise
Thanks,
Because the voice call needs your connection to the operator and that's why the data connection is terminated while the voice call is active.
Happened to me on every phone (LG KU 990, Samsung Omnia, HTC Desire).

You are correct but...3G/H supposed to allow data&voice in parallel, and sometimes is does work such. But once the data connection terminates it never re-established until voice is over.
You are right, but not at all operators, just tested ORANGE SK with HSDPA signal... drops after a voice call is beign made.
BTW, are you GSM or CDMA?
Just learned, that if you are using a custom ROM, can make this problem. Also are you set to WCDMA preffered in the *#*#4636#*#* menu?
GSM
yes - WCDMA is set
Network type - UMTS
Is it just a case of the icon disappearing during the call? Try starting a download whilst on 3G/H/E connection and then make a phone call, switch to the market and check to see if the progress bar is... progressing (excuse the pun!), if it is then data is still active. If your on a GPRS network, data would be disconnected for the call.
Anyone else facing a problem of lost data connection during a call? It happens even even with wifi connection. I sometimes need to use the internet during a call... but the internet connection automatically disappears for the duration I'm on call. As soon as I end the call everything is normal.
When on LTE the phone automatically switch to 3G/UMTS during call (VoLTE is not supported by much providers yet).
During the switch if you're in a bad 3G area or with many people on your cell data connection is lost, the phone gives the priority to the call obviously. LTE is working very differently so that's why you can have a nice LTE data connection and without moving a ****ty UMTS data connection.
I've managed to browse web during my calls without issues on the 5T.
Hi folk, so I've something strange: when I'm on voice call (make or receive) my network change from 4G to H/H+ and internet doesn't work. When call finishes, network go back to 4G and I'm able again to surf internet.
I called my mobile company, Vodafone IT and they told me it's a phone problem (they don't use VoIP) so I contacted Google assistance but since my phone is magisked they can't help me.
Any idea?

This is a normal behavior and has nothing to do with your phone or Magisk: If your carrier does not support VoIP, the phone has to switch to 3G or even 2G to make the phone call. After the call has ended, it switches back to LTE.
I know that this can be a PITA, especially when you are supposed to take part in a Skype or Webex meeting with screen sharing and you are sitting in a hotel with bad WIFI. Then you use the phone as WIFI hotspot. As soon as you call in, your web meeting is unreliable.
Been there, done that. There is no way around this, the only thing which works for me is to take part in the call via my notebook instead of calling in via the phone. Then LTE stays - as long as nobody calls you
@BabelHuber thank you for your answer.
But why this happens?
Why isn't possible to have call and 4G/LTE at same time?

Because the LTE standard simply does not support voice calls.
Hence if you don't have VoIP, the phone has to switch to 2G or 3G. The alternative would be not being able to perform voice calls at all!
