Hi,
I have a Dopod 595. I cannot make calls whenever the phone is synchronizing or downloading email (Push Mail) or even when I have IE running loading pages. I am on Maxis 3G network. The phone has the ‘U’ sign. I thought if I am on 3G network, I can still make calls or receive calls when the data line is being used? Currently, if data is being downloaded, incoming calls will become miss calls automatically. At least when I am on EDGE or GPRS, it will disconnect the data line.
Why is this so? Please enlightened me.
I have a little problem here: If i turn on HSDPA i get the H icon and REALLY GOOD internet speed, but i can't make video calls. If i turn it off, i get 3G icon, pretty good internet speed and video calls. Can't i have HSDPA turned on AND also have 3G (video calls) ?
HSDPA is used only for downloading data when you hvae it on. Thats a little starnge and sounds more like a bug to me than something wrong with the network or Kaiser

Thanks, i kinda figured it's a bug, although it could be obvious for someone who actually knows how this stuff works that you can't have 3G and HSDPA at the same time.
Can anybody try to make a video call while H icon is displayed, please? (no need to wait for someone to answer, i get "can't make video call" immediately, just dial a bogus number)
I rarely get the H icon, only at the aiport at sertain places. But like austinsnyc said, i would have expected it would switch back automatically
As far as I'm aware, you can't make a video call on any mobile phone while there is a data transfer in progress.
Basically the answer is "yes" because a data transfer session and a video call are mutually exclusive, and the phone only uses HSDPA (and shows an "H") when there's an active session, so you can't make a video call when the "H" is showing...
Just to confuse things further, I'm pretty sure it's the network operator that decides how long their customer's phones hold on to an HSDPA connection...
T-Mobile and Vodafone in the UK are the only HSDPA-enabled networks that I've used, and they both return me to a "normal" 3G connection immediately after a data transfer, so the "H" is only displayed briefly - when the phone is actively transferring data.
After the data is downloaded, the HSDPA connection is closed immediately and my phone switches back to the "3G" icon, which allows me to make a video call. If your network allows the HSDPA session to stay active, then you'd need to end it yourself before making a call...
(BTW, this is just my understanding, please feel free to tell me I'm talking rubbish!)
Thanks guys, your info got me a lot closer to the truth (i now know you can have 3G while HSDPA is enabled in settings).
Those really not interested skip this part:
My problem is that i NEVER see the 3G icon and i can't make video calls if i enable HSDPA, even if i don't make a data connection, just enable it in settings (in my network even the name of the operator changes when i have 3G coverage so i know for sure that if i enable HSDPA i never get anything 3G, no data speed, no video call)
To make things more clear: it's like i have two phones:
1. with HSDPA or GPRS depending on location and availability, this is what i get if i enable HSDPA in settings, no video calls, operator name always "Vodafone RO"
2. with 3G or GPRS depending on location and availability, this is what i get if i disable HSDPA in settings, i can make / receive video calls, operator name "3G Vodafone RO" or "Vodafone RO" when 3G not available
I guess this is operator dependent, and it's probably something with my network, but it's really disturbing since i cant have both video calls AND really high speed data, only one at a time with soft reset. I guess i'll call thier customer service.
Sorry for the big block of text...

Pricipally, a 3G phone could handle a PS (packet switch) connection and a CS (channel switch) connection simultaneously. The Kaiser is, however, apparently not in this class. The unability to set up a video call while there is "H" in the display can be due to the network configuration. If the operator uses the same carrier for both "normal" PS and HS(D)PA you can probably perform a video call while you see the "H". If the network uses separate carriers for CS/PS and HSPA it is quite likely that the operator will not let you make a video call while your terminal is listenig to a HSPA-enabled carrier.
I am running XDA WM6 ROM with Radio 2.71.11 (no Cingular fix applied). I noticed that while my GPRS is active that my phone doesn't ring when I have an incoming call. In fact the network diverts the caller straight to voicemail as if I'm out of coverage.
Is this normal behaviour or is it something to do with the WM6 rom and 2.71 not being compatible? I've seen that there is a Cingular fix for this radio rom. Is it supposed to fix this problem or only a problem particular to the Cingular network?
I have experienced this once using 2.69 radio on WM5SEr5.
Turned out something 'went wrong'during startup.
Soft reset fixed it.
BTW: It only happened with an active Blackberry GPRS (via RIM APN) connection.
When internet connection (via Vodafone APN) was active all was OK
I have seen on cingulars website that it has to do with the 2.2* and up versions. It does not allow you to do data and phone at the same time. I ahve a 8125 with the same issue... I use to check my email every 3-5 minutes but changed it to 15 so I can at least make a 15 min call now.
I was hoping that the 2.71 radio would fix that but I guess I was wrong.

I dropped back to the 2.19 radio but it still happens.
No, this is the way how GPRS in GSM works.
Data service and Voice service shares the same channel, so incoming calls are not received when data is transferring. However incoming calls are received when connection is idle, either when GPRS connection is established but no data is being transferred.
There is no way to overcome this limitation, unless you go for a 3G phone (as well as 3G service, for sure)
The ability to make a phone call and maintain a data connection at the same time is a great feature but I noticed that when I make or receive a phone call my data connection is disconnected. Now i know that it's not possible if you're on EDGE or G but why does it disconnect when I have full HSDPA reception?
Hello all,
Have any of you guys come across this problem with your X1...I was connected to the internet via GPRS earlier this afternoon doing a little browsing and have now received 3 missed call notifications which were made during my browsing.
Does the phone not receive calls when connected to GPRS...very annoying.
I'm using the Touch X 10.1 rom by Smaberg but don't think that is the problem...any ideas!!!
some phone operators with older hardware in their end don't support call and gprs at the same time
not really a phone thing
Thanks for the reply...I'm on the Orange network so I thought they would have been up to speed with technology incorporating call and data at the same time...
Same issue here.
I'm pretty sure that GPRS and voice calls can't work at the same time because of the 2G network, but thought at least the voice call would interrupt the data session.

That's my understanding. 3 & 3.5G allows voice and data at the same time.
but on 2G it's either GPRS or voice... that used to drive me crazy with my Prophet too
Ah, that makes sense...I usually turn off the 3G to extend battery life so that would be the reason I missed calls...may turn it back to 3G if I'm doing a session of browsing in future...
Cheers
even with my 2g himalaya I didn't have any problems with both calling and gprs
it was why gprs was interduced to replace the slower and older gsm dataconnection
which worked the same way as an analog modem which blocked of cause
of cause only class A gprs devices support that
http://en.wikipedia.org/wiki/General_Packet_Radio_Service#Hardware
but all these phones today are that
problem is that class A is required in both the phone and the operators network hardware
Try with RADIO ROM 1.16.
Problem with this rom is apparently solved.
