Using GPRS and Phone at the same time (O2 IIs)

I've had all three HTC products and really love the IIs. I also have a T-Mobile branded IPAQ 6315. On the IPAQ, I'm able to use GPRS to surf the net, and at the same time I can place calls, which is really helpful because I can view the screen while surfing and have the speaker-phone on so I can talk and look at the screen at the same time.
When using the IIs, I'm only able to use one at a time, or so it seems. Does the IIs have the capability of using both at the same time like the IPAQ? The IIs I bought has never been locked and was purchased new.
Thanks for your help, I live in the States.

Good question...
Any answer...
Come on we can't let HP beat us on this!

Hi,
well, this kind of feature will most likely never be available to an XDAIIs/MDAIII. What determines whether that is possible is the class of GSM chip being used. The iPAQ 6315 appears to be using a Class A chip, whereas the XDAIIs/MDAIII seems to have a Class B chip (http://www.gsmworld.com/technology/gprs/class.shtml).

Is your HP a CDMA version orGSM?
On GSM, you can't do GPRS and Voice at the same time - GPRS is suspended. Technology limitation.
UMTS you can, and I think CDMA2000

As said above: http://www.gsmworld.com/technology/gprs/class.shtml. You can with Class A.

On my motorola phones the phone rings and the gprs stops. On the pda2k it just merrily keeps working and the phonecall goes to voicemail.

This is something I'd actually like to turn off as I prefer being interrupted if someone is trying to get hold of me.
Anyone know how its done?

Very clever - this is a TECHNICAL SPECIFICATION.
Can you name ONE device that is GPRS Class A?
For the other user - GPRS has been setup by most operators to be a secondary service, or in other words, a GSM call should go through. The only time this won't happen is if you are intensely receiving data for >2s, eg like during a mail sync or ftp download, where the GPRS modem is going flat out

it doesn't work
I used to use it with t-mobile on the 6315, and costumer service told me that it will never work, hardware limitations!
In fact every time i was online, I will miss calls and the will go to voicemail, not even ring!
I was hoping for it too!

:evil: :evil: :evil: I am looking for the same answer as well. Is there a settings on the IIs so that I could either take the call or deny the call while I am on GRPS session?
With the SE P910i it will do that with some tweeking on the connection name that may be specific to my operator (FIDO).
I used the following connection name on the P910i everything works perfectly afterwards:
<account name>
However, the PocketPC OS do not like <> characters in the connection name.

Sony Ericsson P900 (my previous phone)
If you put GPRS/GSM on auto it quite happily let you do both at once. Occasionaly it warned you that outgoing phonecalls would suspend GPRS and likewise it dropped them on incoming calls, but 95% of the time I could surf+talk at the same time :-(

use O2 XDA Exec with BT sim ????

Nuubie now very lost after 14 hours.
I have been trying to get my XDA Exec to work with a BT sim (UK). It does not appera that the unit is locked because it does allow me to select the following networks..
VF-UK
O2-UK
T-MOBILE-UK
23420 ?????
Orange
I have tried all the unlock proceedures I can find and various different ROM's to no avail.
When I set the phone to automatic it logs on to UMTS-UK.
Can anyone help me....or is it not possible.
I read that the XDA is not locked, so am I doing something wrong?
I have also tried this
http://wiki.xda-developers.com/index.php?pagename=Uni_Simlock_by_Buzz_and_team
But am unsure of how to do 9 and 15......can any one help with this

The xda Exec is DEFINITELY not locked to any network. It could be either the phone is barred, or the SIM no longer works (BT SIM? I've never seen one of those since I came to the UK 6 years ago; surely BT Cellnet is now O2...)

Thanks Richardlai,
The BT sim works fine in other phones. With the BT sim in it automatically registers to a network called UMTS VF-UK that works fine but the coverage is pants.
What is this and who is it?
Could it be that there is a setting in the XDA somewhere?
Has anyone got an XDA working with a BT sim?
If the phone is barred, how can this be changed?
Can any other XDA Exec user tell me what networks are listed.
go to start>phone
click on menu>options>network (tab)>change network selection to manual. This brings up a list, my list is
@ VF-UK
@ O2-UK
@ T-Mobile UK
@23420
@ Orange
to stop any changes happening just click cancel.
Thanks

That's weird... "UMTS VF-UK" is Vodafone's 3G network. How old is your SIM card? I suggest to contact BT (I'm assuming you're referring to British Telecom) about this problem, and they might be able to refer you to the right people from O2 (used to be BT Cellnet).
If you're phone is able to connect to a network, then it is not barred so don't worry (a barred phone cannot be used again in the same country as its function is to disallow the thief using the stolen phone; this process cannot be reversed, as far as I know).

BT mobile piggybacks on the Vodaphone network, so you are connected to the correct network. Perhaps the UMTS signal is too weak. Try disableing UMTS and see if everything is okay just using GSM.

Oh... I didn't know that BT has their own mobile phone service now...

I don't know anyone who uses it. But I remember the fuss when a year or so after selling off Cellnet/O2 it moved back into the mobile business. Presumibly as soon as it legally could (http://www.btmobile.bt.com). Like Virgin it's a virtual network.

Thanks, So it looks like I'm looking in the wrong area. The problem is when I ring BT they tell me that they don't support that phone.
When I set the phone to GSM only, it logs onto VF-UK the problem with this is the signal strength is very low, typically I can't get past 1 bar when I copmare that against a normal phone on VF that would have 5 bars. Could it be a fault with the phone or is the XDA a bit like this.

Why don't you give us the specifications of your phone, especially the radio stack verison and ROM version?

rom version 1.30.107 WWE
rom date 04/11/06
Radio version 1.09.00
Protocol Version 42.42.P8
Extrom version 1.30.162 WWE
I hope this is the right information. Does this tell you anything?

Well it does seem to be the latest O2 ROM...
I have heard of some rare cases where the Universal's radio reception is very low, and apparently it was to do with a loose connection of the antenna to the circuit board. You'll have to do a search on it I'm afraid.

I have the O2 XDA Exec and I run the BT SIM in it with no problems.
My Rom version is 1.30.107 WWE
My Radio version is 1.09.00
Ext Rom version 1.30.162 WWE
BT Sims use the Vodafone network.
Keep well

Query: Simultaneous GPRS data transfer & Voice call

I have an MDA C3. When web & walk is transferring internet Data and a call comes in, the phone does not ring. It goes directly to the voicemail.
T-Mobile customer service tell me that this is correct as you can either transfer internet data or make a call.
Is that right? I thought that was with WAP which is analagous to dial-up. Surely GPRS is analagous to Broadband.
Anyone else want to try this:
Go to Web & walk home page. Attempt loading up the guardian page (This will take a while). Whilst this is loading, call your phone number and see if it rings or goes direct to VM.
I spend lots of time browsing so I must be losing lots of calls!
Feedback greatly appreciated.

From what I have heard only UMTS devices can support simultaneous voice/data.

Yes - but not GRPS that uses GSM band instead of UMTS.
However, some devices have troubles keeping the data link active when a call comes in.

I am having the same issue (also on T-Mobile UK).
Then IE is running or AS is downloading my mail (I use direct push) all my calls go straight to voicemail.
This is worrying as I just moved over to T-Mobile for the web n walk package to allow me to have instant e-mails. This is a pain if it means I miss calls whilst my mail is downloading.
You'd think that the chances of the 2 coinciding are slim (I don't get a lot of mail, maybe 10 per day) but the wife has already complained 3 times since Friday that she went straight to voicemail, and each time it was exactly as i got a new mail.
Is this a limit of GPRS, the Orbit or just T-Mobile?
Thanks
Dae

I was surprised too... Thats why I posted the query. I thought my phone and/or SIm were faulty. But T-Mobile tell me thats how its supposed to work.
With W&W and Email, Its really hard for someone to get through with a voice call. It was worrying for me as I tend to browse the net whenever I am waiting around. This means that when I am on the bus surfing, no one can get through to me!!
Surely if there is a limitation, then the phone should give precendence to the Voice call. After all, you can pick up your emails or surfing where you left off.
I would really be interested to see if this is a T-Mobile only problem.

No itschase is spot on.
It's not a t-Mobile problem, it's the same for any GSM based network.
Only 3g (UMTS) phones can do data and voice at the same time. No matter what network you are on.

I have just run an experiment in the office as follows:-
Me (artemis with v3 black and blue) - Voicemail when data active
person 1 (MDA compact III - v3 black and blue) - Voicemail when active
person 2 (hermes) - no Voicemail when active.
We are all on t-mobile UK, and therefore it doesn't look like a network issue, but maybe a ROM problem?

What problem? Everything is working as it supposed to. If it's so important to you. Go buy a 3g phone!

I now fully appreciate that 3g phones are the only ones to support this type of behaviour.
I was trying to be helpful and post the results of my test as at that point I didn't realise that only 3g phones worked as such. I was lead to believe this by wikipedia:-
"Class B
Can be connected to GPRS service and GSM service (voice, SMS), but using only one or the other at a given time. During GSM service (voice call or SMS), GPRS service is suspended, and then resumed automatically after the GSM service (voice call or SMS) has concluded. Most GPRS mobile devices are Class B. "
Obviously this is not the case.

I incorrectly assumed that whilst browsing, if a voice call comes in, the phone would give priority to the call.
If I had known what I know now at the time I signed my 18M contract I would have bought a 3g Phone! Its just annoying that i'm stuck with it for another 12M. T-Mobile push the fact that they have set the internet free... but what they fail to get across to everyday users is that its "AT THE EXPENSE OF THE VOICE CALLS"

Because T-Mobile forced you to buy one of their 2.5g phones rather than one of their 3g phones?

I have no problem receiving phone calls while browsing the internet on the P3300.

Neither have I to be honest, the issue only arises while you are actively downloading data. However once the website has loaded, you are free to accept calls again whilst still looking at the site in the browser.

As a test I started downloading a dummy 32MB testfile on my P3300 (from speedtest.bbned.nl) and I called my mobile with another phone.
There was no problem; I received the call while downloading the file.
Maybe it depends on the operator? I am in Holland on T-Mobile

Hi,
It's not enough to have a class A (2G) device, but also DTM (Dual Transfer Mode/Simple Class A) support has to be active in the specific network, otherwise only 3G device on 3G network will provide Class A (simultaneous voice & data).
In fact, there are quite many models from Nokia during last year that support DTM, but as already mentioned, it's not enough.
FYI,

Is that an EDGE network ?

I got the Artemis with PV Black&Blue v3 ROM.
I can receive calls while pages are loading in IE.
I think this is a provider problem.
The phone provider has to intercept your GPRS connection and establish the GSM connection. Maybe T-Mobile just rejects calls while a GPRS connection/transfer is active.
A1 intercepts the page download and my call comes in.
When I pick up, the GPRS connection is closed completely. (not just pending)
So receiving calls while surfing is no problem for me with Austrian A1 provider.
Any other experiences?

GSM connection drops in Belgium & Luxembourg

Hi guys,
I had a strange problem this weekend, my P3600 (bepe rom, dont now the version), works fine in Holland. But when I drove into Belgium the phone switched over to the Belgium T-Mobile, and the connection was gone! The phone tried to re-connect and each time there was an connection for a few seconds, and then it was gone again.
This lasted no matter what I tried. I used the connection Wizard to set the settings the the Belgium network, but that didnt work also.
The phone became terrible slow and even the GPS function was affected (tomtom was not able to find the gps device). After shutting down the gsm with the commanager everything worked fine again, but I was not able to make a call obviously. Back in Holland the phone switched to the Dutch Tmobile and calling was possible again.
Has anyone have this problem before?
regards,
Ron

belgian user here, and never had those kind of problems. maybe the problem is the operator you were supposed to switch network to (depends on your local operator, and which belgian operator he is supposed to work with). maybe you should try switching the band manually to avoid 3G connections, and to force GSM connection. these are the only kind of connection problems I've met here in Belgium...
hope this can help...

I use Vodafone and just finished a trip to Luxenburg, Belgium, France and Germany and then back to Netherlands. I use Karmba ROM and had no problems..

thanks for the quick replies guys!!! i tried to set the gsm operator mannually, but it was pretty hard doing that, as the phone was occupied searching for a network. (errormessage "phone busy"). there is a list with preferred operators in the phone settings part. i think that could be the problem. can somebody with a positive experience post his/her settings? For T-mobile Holland that is ofcourse.
thanks!!!

ps. 3G was switched off

Whos ROM

Whos ROM are you using? Try Karmba_a....v.3.0

For good reception in Belgium you really should use one of the big three operators: Mobistar, Proximus and Base.

maybe a problem of the radio rom?
what version are you using?

belgium doesnt have a t mobile network afaik

Try a different radio rom.
Here you are some,I hope I can help you.

Indeed, that's why I recommend only the 3 main operators.

tnx guys!
I will give my Trin a new Radio rom and check what will happen then, it can't be that difficult I suppose
btw I used al the operators my phone was able to see, and it didnt make a difference..... strange....
If I have more problems, I will drop a line
tnx again

How to re-enable GPRS for HTC Twin1000 (T5399)?

Hi, guys,
I got a HTC T5399 which is said to be Twin 10000, this dual mode phone is on the China market, customized for China Telecom CDMA2000 network, although it also supports WCDMA at the same time according to its brochure.
My problem is that GPRS functionality is disabled deliberately by the manufacturer when I want to use it under WCDMA network with my UK O2 sim card. Of course the voice calls are fine under WCDMA as it's supposed to. When I attempted to establish a new Internet connection, the options of line types are only three types: cellular line, bluetooth and Hayes modem on com port, there is no option of GPRS cellular line available as normal WCDMA 3G phones do. I tried to set up the connection with cellular line anyway but failed to connect to the network.
After googling on the Internet without any progress, I finally have to come here for help, as this website is for the best WM experts in the world. If I can not get it solved with your guys help, I don't think it's possible to sort it out anywhere else.
Thank you very much in advance for your kind support!

Sorry, forgot to let you know, the above device OS is WM6.5, details are
Windows CE 5.2.21869 (Internal version 21869.5.0.82)

Desperately awaiting feedback.....

no solution???

sadly, no one knows?
