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...

I can make calls with a 3G sim as the 3G network switches to o2 when it is unable to recieve a 3G signal, but I cant get GPRS to work, can any one help? has any one got a 3G sim to fully work with their XDAII?
I will post more info if required
Thanks
Jud
If im not mistaking, the data trafic is locked to a specifik 3G network?
if it were me i would ask 3 if they support grps
and if they did to turn it on

AFAIK, if you are a Three customer, all of their services are available in proper 'Three' coverage areas.
BUT, they make it clear on their site, that in none Three coverage areas, coverage is then provided by O2 under a 'roaming' agreement Three have with them.
They point out that in these conditions, voice calls and sms are still possible (as this uses standard GSM, or rather CSD).
BUT, that picture messaging etc will not be possible.
This seems to indicate quite clearly, this is because a GPRS arrangement with them is not possible, or established.
Thus, in your case, a Three SIM card will work in an XDA (but only the OLDER ones allegedly, Three supposedly got sick of too many people buying them for just the high amount of free inclusive minutes and sticking them in their own handsets and incurring high roaming costs for Three with O2, so locked the newer ones), but GPRS is not available when in a none 3G handset, or in truth, on a none Three network!
Hi
Im on a Three network in Australia and i am able to use the three sim in my XDA however, I am unable to send sms as it cant read the sms function from the carrier sim. I have change to an optus sim and sms works on that, so im sure its just three's sim that doesnt.
Anyone having a similar problem ? and have a fix ?
Hi, I have Austrian 3 sim in my XDA II and GPRS works, however (of course) I am using national roaming partner's (A1) network, because XDA does not have UMTS radio.
Everything works OK. data, sms, email....

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.
Mark
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.
Mark
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?
I have two Dopod 810 running on Optus network. One running windows5, the other windows6 Dopod release. BOTH phones have the same problem of repeatedly disconnecting the phone call if the phone settings are
Network …… Auto
GSM/UMTS ..Auto
So to correct the problem Optus told me to change the the settings too
Network ……GSM
GSM/UMTS ..GSM(900+1800)+UMTS(2100)
This would stop the drop out, but I now don’t have 3g network, hence no MMS, video conferencing, web access is at dialup speed.
I had the Optus service department take both phones and they found they could not replicate the problems, installed the windows 6 pro upgrade on them and sent them back. Guess what, I still have the same connection problems. Put the phone settings back to the second settings above and have a phone back, but none of the 3g.
Any ideas why and what I can do? The only thing I can think of is to get Optus to replace the sim cards and see if that helps?
Ohh and this has been a problem since the phones were new.
I have the same problem too in indonesia Telkomsel network.
a incoming and outgoing call always drop or disconnected. and really difficult to setup a call. and very often my voice couldnt be heard.
anyone can help me?this is network failure or handset failure?
thx in advance
With my older phone, if I have a GPRS data connection, incoming voice calls will be rejected (busy). I was told it is the same with all phones.
Can HD2 make or accept a voice phone call when it has a GRPS connection? Or an HSPA connect? With the My Location, Weather, and Direct Push, I can neve tell when my phone has a data connection. Does it mean I may be missing calls all the time?
I have no problems with my telco. They will "downgrade" my data connection whenever a call is coming thru.
Nope - works fine for me. Will be using MSN and then a phone call will over ride it

what phone would do that? You wouldn't happen to be with Verizon before, would you? My gf has a blackberry on verizon and whenever she's using the net incoming call would be rejected. I don't know any gsm phone would do that. I've had 5-6 GSM phones and they would allow incoming call and suspend your current web until the call ended.
Well, voice calls are made on a certain frequencies and data connections are made on others.
Ex: in my country the data connection is on the 1900/2100 freq, while the voice calls are on the rest.
So it should never be a problem. I believe its also the ability of the phone to use different freq for different tasks.
Thanks. I can now use the data connections without worry
Why not you try yourself. COnnect to data constantly and make a call to your number. What will happen...?
3G and GPRS/Edge won't block calls. But you can still use old fashion data-call. While I doubt any provider would provide data connectivity this way, I can't rule it out.
I have found problems while making VOIP calls using SIP (soft phone) software on t-mobile, UK 3g network.
I got various sip client installed my HTC HD2. They all are working very well on wifi connection. But not working at all on t-mobile UK 3g network. I get registration failed error.
I found following link (https://www.t-mobile.co.uk/shop/terms-and-conditions/combi/) in which they have mentioned that
<b>
"you can't use your phone as a modem or use internet Plus for peer to peer file sharing, or making internet phone calls. *[Internet] Plus comes with a fair use policy of 3GB a month."</b>
So I am wondering whether T-mobile is blocking my access to connect to my VOIP provider. Although, I can use skype mobile on t-mobile 3g network to make skype to skype calls.
Guys,
Is there anyone who is able to make VOIP call using t-mobile, uk 3g network or any of the other UK provider? If yes, then please help me to figure out what’s wrong in my settings.
Thanks.
As many people have found on T-Mobile for various data connection problems, , try this
settings/menu/connections/manage existing connections/proxy settings tab/remove the tick in the "this network uses a proxy server to connect to the internet" box.

Already tried this, but no success. So wondering is it possible in UK to make VOIP calls using any 3g network.
Guys Please post your VOIP call experience on UK 3g providers.
You could try getting VPN to work?
It is true that indeed some providers do block certain ports/protocols to enforce their terms of use.
Vodafone NL started with this too some time ago..

I don't use it much but I've had no problems using Skype on 3UK.
I'm with T-Mobile UK and can use Skype without problem on HD2
Vodafone NL blocked some ports

Hi there,
I have also noticed that Vodafone NL has blocked some ports such as for Rapidshare and Megaupload !
Is there a work around for this?
Thanks

hi
I have tried many times with Softphone 3.0 and it does not work. My mate has swapped the sim card into his iphone and with o2 it registered without problems. it seems tmobile is blocking port 5060 for sip connecitions.
Fring somehow works but Softphone is much better, under Wi-Fi it quickly connecter my friend calling me to my Voip-in number (voipcheap). fring can fail with this.
let me know if you have found some clues how to make it work.
thanks
Hi
I am also facing the same problem. I can make jumblo calls( voip provider) if my wifi is connected.
But it does not work with my t-mobile uk 3g connection.
Please advice.
cheers
