Can someone tell if ROM versions RUU3.16.52 and RSU3.23.01 finally support GPRS Class B, thus if incoming (or outgoing?) voice call will NOT disconnect current GPRS connection?
TIA.

I'm trying to write a program in VB.Net that establishes a GSM data connection from my XDAII to a Siemens M20T GSM modem.
I've been looking in the .Net documentation, and from what I've read it's unclear wheter I should better use Connection Manager (with the corresponding C++ code) or should call the Phone API :?:
Does anybody have any experience with gsm data calls?

Hi everybody
I have recently started to use "push" email on my XDA Exec and so my data connection is active all the time. I have found that when I am in a 3G coverage area, I occasionally miss incoming voice calls (about one in five got missed in my testing today). The caller gets diverted immediately to the voicemail system. This does not occur if I don't have a data connection active, or if my data connection is a GPRS one.
I have contacted T-Mobile to ask about this and they tell me that it is not possible to receive a call when there is 3G data being transferred. I am not sure about this since I thought that one of the advantages of 3G over GPRS was that it allowed a data connection and voice connection simultaneously. Indeed even a GPRS connection gives priority to an incoming voice call so that the call can be received and the data connection gets suspended for the duration.
Does anyone know how to make the 3G data connection not prevent incoming voice calls.
My phone is an O2 XDA Exec with radio version 1.09 and with a T-Mobile Web'n'Walk SIM.
Thanks in advance for any help.

I'm sorry I don't know the answer, but I can tell you I have the exact same issue (O2 Exec with T-Mobile Web 'n' Walk SIM). I got fed up with missing practically every call. ..instead I get voicemail a few minutes later. I'm stopped using push e-mail with a hosted Exchange account and I've reverted to checking via POP every 15 minutes or so, to see if that helps.
Thanks for the confirmation that it isn't just me, Izzard-UK.
I have done a bit more testing and discovered a few more things. It seems that I always receive the call if my phone hasn't received a call for a while, but once I have received a call, I can't receive a call for several minutes afterwards(I don't know how long but it is in the tens of minutes). And just to confirm, this is only if I have a UMTS data connection at the same time. Without the simultaneous data connection, all is well
Izzard-uk, can you confirm whether this "first call works - subsequent calls don't" behaviour is the same for you as well.
For me, the temporary fix is to send my phone to "GSM" instead of "auto" so that it uses a GPRS data connection instead of UMTS. Of course, data transfers are much slower but I can live with that!
I am going to try upgrading my radio ROM tonight (to 1.13) to see if that makes any difference.

I have tried upgrading to radio version 1.13 but it made no difference.
Does anyone have any other suggestions?
Thanks for your help.

Hi Guys,
I use TMC option of TomTom on my Universal with data connection always on (essentialy UMTS 3G) and email checking every 30min and I can receive calls without any limitation... I did it with 1.09 radio rom and actually 1.13 radio rom.
Everything is ok for me. But I noticed that on UMTS (not happening on GPRS only), signal indicator is set to 0 when I wake up the universal and get real signal strenght after few seconds. But I can receive call any time...
When i was with orange and had a 3g signal i could surf and talk, i also though this was the normal with 3g....
How ever on t- mobile it seems not my phone is set to check email every so often so im always getting missed calls where they dont get through when the mda is checking emails so ive had to lock it to 2g annoyingly enough
I have an O2 contract as well as T-Mobile and if I do a test with my O2 SIM in my Exec I don't see the missed calls problem at all. It seems to be only on T-Mobile that I have this problem.
Unfortunately, as I said in my original post, T-Mobile say that it isn't a problem because simultaneous voice and 3G data isn't supposed to be possible!
Argh!!!!
I suppose I will have to put up with it since their Web'N'Walk deal has no competition at the moment in the UK.
Mark
whos says its not actually possible out of interest?
I raised this as an issue with T-Mobile Customer Services. They asked me to make a list of when missed calls happened so that they could trace the calls and determine the reason. I did this and sent them the details - out of a total of 19 test calls over a 24 hour period, 5 had gone straight to voicemail even though I had a perfectly good signal at the time.
But the annoying thing is that, after going to all this trouble, they just sent me an email by return saying that it was not possible. I have quoted the email below.
Hi Mr Burgin,
I have just received feedback from our engineers who have tested out the problem you have described. The has advised me it is not possible to receive a call whilst transferring 3g data. I hope this sheds some light on the problem you were receiving.
Regards....
Not a very satifactory answer, in my opinion.
Mark
Hmm, no that's rubbish! Clearly other operators can manage it. You just know this is a checkbox in some management software somewhere:
"Allow telephony during UTMS transfer? Yes/No"
I've gone back to my HTC Wizard. Yeah, smaller screen and no 3G. ..but it feels a lot snapier than the Universal I've been using. And I can receive calls now, too!
Mark, I've had a thought. Do you (like me) have an old 5v T-Mobile SIM.
These SIM’s can be identified either by SIM serial number 893044 05 or 16 – up to and including 893044 50. SIMs with serial numbers 893044 52 and above will be ok- anything lower is likely to be a 5v.
There was an issue when I 1st got my MDA Pro. It had to be network unlocked by T-Mobile for it to work with my SIM. Is it possible that the ROM update as "re-awakend" this problem?
Hi Guys,
OK, here's the situation. I have an Orange SPV M600. I have an Orange SIM card inserted that has *NO* GPRS functionality (it's my corporate SIM card and they've locked down GPRS for everyone).
What I'm trying to do is dial up to the internet using dial up WAP. What would be the settings for these? All I want to do is be able to maybe send and receive POP emails on the device and maybe slowly browse the internet occasionally.
Any ideas? What would the setup setting be? ANy contributions gratefully accepted
You mean you want to dialup using plain old CSD? That would be easy if that's the case - just setup a new connection and punch in the number of the modem pool of your ISP, and that's it. You got 9.6 baud, unless you have HSCSD - but given that your company locked down GPRS....
normaly WAP also use the same "modem" as gprs
and the diff betwene real grps internet and wap is
handled at the server side depending on the AP
Changed my mind...dual SIM is now the solution!
Thanks Guys
I came up with a different solution though. A Dual SIM adapter. One for my workplace SIM and I'll buy another PAYG SIM with the cheapest data charges and switch between them when I want to make data calls etc. Seems like an ideal solution However, that opens another can of worms....
Which Dual SIM adapter do I get? It has to fit the SPV M600 (HTC Prophet) and I like the idea of being able to switch SIMs whilst the unit is online but I understand these ones really drain the battery. The other one, I understand, does not require power but to switch SIMs, you have to power the phone (or is it unit?) off and on again. Hardly an elegant solution!
Hey all,
As far as I understand; when you are on GPRS you can't make a call or receive because it ties up the line.
Does the same apply with EDGE? I don't think it does with 3G but my network just went EDGE over GPRS (o2) so I wondered about the 'new' technology.
Thanks for the advice
it dont apply to any of them unless thats a limit of the phone company one is connected because they have limited equipment

I always thought it did; I used to be Vodafone UK; I started on one of there GPRS phones & couldn't attempt or rec calls, I then moved up to 3G, again on Vodafone & I could run 2 sessions of them easy. It would't be to do with the 3G networks having there own network settings? for example, the 3G phone would give me the option to connect to 2G or 3G when I first turn it on or change networks.
i use GPRS it dont block anything for me
only tech which really block 100% is the old callup modem data calls
which also only operate at something like 9600Boud
GPRS Data Call
Hello, i´ve been trying to find an answer to a problem while calling through GPRS with VoIP using WM6VoIP.cab released here in xda-developers. I can make the call, it rings in the other side, but no sound for either users... There is no sound at all, like if the phone was off. On the other hand, i use the same system to call while connected to a WiFi Lan, and it works perfectly! What could be happenning to me? I use Vodafone, and i´ve also tried it with Yoigo which uses Vodafone network...
I´d really appreciate your help!

GPRS and EDGE are basically the same thing with respect to blocking voice calls.
Old GPRS implementations (can't remember which class - wikipedia is your friend) would block incoming calls - but newer implementations shouldn't. The only thing is when you have active calls, GPRS is suspended.
But I heard that the radio firmwares and equipment of the telco would make a difference.
When I had my Treo 750, I always had a GPRS connection. If there was any data activity going on, incoming calls would go to voicemail. Very irritating, especially when using Direct Push for email.
With my old Blackberry Pearl, and my new Tilt, I always have an EDGE connection, and do not have the issue.
Hope this helps...
Hello:
I've a sim of telco1 (with a cellular number) but the traffic data trough this provider is very expensive...and I want to buy a sim card of telco2 (only for DATA EDGE)...can I use the both cards at the same time...in other word, can can I receive calls (trough my telco1 line) while I'm using the data connection (trough telco2 sim)...I've a Qtek 8300 smartphone with WM6.
Best regards
any idea about this situation?

Oldsap:
Is the only option to change the phone, or can I use a software solution?
Best regards
IMHO, i don't think there's a software (right now) that will allow you to use 2 simcards simultaneously
i believe that software alone is not enough
the radio stack would have to support it too
