Incoming Phone during data connection - HD2 General

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.

Missed calls when I have an active UMTS connection

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?

EDGE & GPRS on call

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...

Calls sent to Voicemail if Data is Active

I have an unlocked Hero on the o2 network in the UK.
I have been noticing that a lot of calls are diverting straight to voicemail without ringing. It appears that this occurs while in a 2G Network Area.
2G Networks cannot cope with both Data and Voice calls at the same - so if, as you would expect on a "Smart Phone", a data connection is active - i.e. Push Email, Updating Twitter, Facebook or streaming Radio - then you are unable to receive calls!
This is not an issue on a 3G Network.
I have read that a phone should be able to terminate the Data connection if a Phone Call is coming through. It would appear that the HTC Hero does not do this - incidentally I have read of similar issues on the iPhone.
Has anyone found any solution to this? Is there anyway to ensure that the Data Connection IS terminated when necessary?
Thanks in advance.
bump for the Sunday crowd...
It's not the phone that terminates the connection, it's the network. When it knows it needs to route a call to a phone which has an active data connection, it should terminate the data connection, or at least suspend it (HTC's are capable of this if commanded) and then route the call through.
Networks that route through to voice mail without ringing are not doing this, they are simply routing straight to voice mail without bothering to try and contact the phone.
Nothing you can do about it apart from keeping data turned off whenever you are not using it.

Using google voice for calls and texts

I am thinking about just keeping the data plan on tmobile and canceling the voice plan and text plan and use gv to make calls and texts. What you guys think?
If someone texts you, they will charge you. Get unlimited data and text, I think that's better. I wouldnt just rely on data. No data means your phone is an expensive brick.

i said keeping the data..and just the data no voice service. is that possible?
You can I am thinking about this myself you would need to set up a SIP account and something at pbx.org
Google Voice is not a VOIP service. Google Voice forwards calls dialed to your GV number to some other phone number(s), be they cell, land or sip/voip lines.
Your solution would only work if you have an active and functional sip/voip connection up and running on your phone full time.
GV text messages will work on data only accounts, though.

No, that won't work. Your problem is that the phone has to have some way for the Google Voice server to send it a phone call. This is done by sending it to a phone number (or a gmail web account on a laptop/sesktop with the appropriate browser plug-in).
The phone number can be any phone number (land, cell, voip, sip, whatever).
If you cancel your voice service on the phone, the only way GV has to contact the phone is the data connection, which means you'll need a working SIP account.
The Nexus S does support SIP calling out of the box (but I'm not sure if it's over WiFi only). The setup for it is done in Settings, Call settings, Accounts. You'll need a server and account info. Then tell Google Voice to forward calls to that account, and they should forward to the phone that way (in theory).
Note the warning that having the phone receive internet calls (SIP) comes with a warning that it "reduces battery life." The reason for this is that to ensure you don't miss a call, a full time data connection will have to be maintained; this will be a serious battery drain on the phone I believe.
The point I was trying to make was that Google Voice is not really a VOIP solution the way traditional VOIP services are. It's more like one than it used to be now that you can actually make and receive calls from a web browser, but that won't work on the cell phone, especially for the incoming.
I may try setting up a SIP account on my phone to test this out sometime this week; but frankly, T-Mobile's 3G service is so spotty, especially inside buildings, that it would never serve as an acceptable voice service replacement. YMMV.
I use Google Voice with a data plan but no text plan. I do have a voice plan. You need to give out your GV number to everyone for texts, and then you can block texts through T-mobile and not worry about charges. GV doesn't support picture messaging and if someone sends you a picture message at your GV number it just disappears into the aether and doesn't notify you or the other person that it wasn't received.
There are ways of using GV without paying anything (detailed on this forum). Using a gizmo5 account allows for free incoming calls, and using an app to have your outgoing calls "call you back" on your gizmo5 account allows for free outgoing calls.
I have to disagree about the battery life and GV not being a true VOIP solution. With the addition of a SIP carrier of some kind (preferably gizmo5 for free calls) then it works well. Battery life is fine having my phone constantly registered with gizmo5 servers over data to accept incoming VOIP calls. No need to use a web browser.
But I have to agree with distortedloop about needing a high quality data connection. Unless you spend all your time near a 3g tower you're going to find plenty of times when you have no 3g data and therefore no good calling. You don't want to use VOIP over EDGE. It is nice that when I'm at home or office where I have my own reliable WIFI that I can use my cell without using any minutes. But I wouldn't trust it to be available when your car breaks down on some rural road.

I agree with this.
GV is something I wouldn't rely on 100%.
I have the cheapest voice plan with unlimited data and text. When I make calls, I use GV and when I receive I have my voice. That works for me and I pay 67 a month.

Using Google Voice When Throttled (T-Mobile USA)

So, yeah, I used 5GB and got throttled to 2G speeds by TMO. I'm not really complaining since this wasn't a normal month for me. What does suck, however, is that now when I get a Google Voice call, it keeps cutting out during the conversation which is really, really bad. This is because the 2G connection simply doesn't provide enough bandwidth for GV to work well. (When I'm not on wifi and using the throttled 2G.) I know there isn't really anything to be done about it, just pointing out that it sucks.

He's talking about phone calls over google voice it looks like, not voice mails. This would most likely be the reason he hit the limit.
Damn! I'm soooo tempted to chuck t-mobile and go with sprint's truly unlimited plan. Its just way to much money though! $99.99 (before tax) + $10 4g speed upgrade - man that can break me!

Its only that expensive if you want unlimited minutes to land lines. Their base plan is $70 and has unlimited calling to any mobile (not just sprint, but any mobile phone) along with unlimited text and data. Its actually a really good deal, but CDMA/WiMax sucks so bad... I really don't think I can pay more for worse speed and locked devices lol.

Oops, my bad! That is certainly a bummer.
Yep, I'm talking about voice calls through Google Voice. The thing is - I'd be willing to pay like $30 to get another 5GB of high-speed data until my next billing cycle, but there is no way to do that, I'm just stuck! (The data this month was definitely an exception - I'm typically around more like 2.5 GB for the month.) The funny thing is (as Lawalty mentioned) that I've been watching Sprint closely and am seriously considering switching to them in 2012. I guess I'm not the only one.

I haven't ever gone over my 5 GB cap, but i'm looking to get away from T-Mo bcause of their impending merger with the Evil Empire. I originally left AT&T and took my iPhone (original 2G) to T-Mo cause I was fed up with AT&T's crappy coverage and high fees, so I certainly don't want to give them any more of my monies.
I just haven't found a plan similar to T-Mo's Flexpay on any other carrier. I don't want a 2 year contract. That was the thing I loved most about T-Mo, I never had a contract with them, and sometimes I skip whole months without paying for service, but I still get to keep the same plan. Plus, they pro-rate the cost of my monthly bill.
If I could find something like that with Sprint or Verizon, then I would certainly switch.
I had flexpay and it was a pita! Eventually had to make a new account just to upgrade! Now they think I've only been with then a year when I've been with them 7! Oh well.
You must be using GV + SIP to make VOIP calls instead of 'regular' use of GV, which uses a cellphone connection and so your minutes. I've used GV on T-Mobile for business for years, thousands of minutes a month, and with negligible impact on data usage. GV only uses data to login to my GV account and to download the voicemail audio files.
T-Mo's unlimted voice, text, and data (1st 2GB unthrottled, plenty for me) for $50/mo is by far the best deal available.

I should have clarified that - my data usage was not due to GV, I went over the 5GB limit due to tethering during an internet outage at home for a couple of days. GV seems to still use some type of control connection or something that causes the calls to cut out frequently when you are on a really slow connection. (My speed tests while I've been throttled have always shown less than 64kbps.) I'm not sure how it works, I just know that GV worked great for me until I got throttled.
Makes no sense. I often make perfectly good GV calls out in the boonies with no data connection at all. GV uses a standard cellphone connection like any other call. Your data speed has zero to do with call quality.

I'm not sure about that, The Google Voice troubleshooter states:
"If you’re using a mobile device, ensure that your carrier network connection is strong."
Which would indicate to me that you do need a data connection. I've only noticed this on incoming calls, so maybe outgoing calls are different. In any case, later tonight I'll run some bandwidth tests on my router at home and make some GV calls while on wifi to see how much bw it looks like it is using (if any.)

Crashdamage is correct.
Google Voice only uses data for two things:
1) text messaging
2) whenever you place an outgoing call, it will ask the Google servers what "Voice" number it should call (instead of whoever's regular number) so that it will display as your Google Voice number on the receiving end's caller ID. If your GV app is updated, it should only have to do this once per person. Once it has that number, it places a call to it through your regular cell phone connection.
Incoming calls don't use the data at all; Google's servers will receive a call placed to your Google Voice number, and they will reroute the call instead through your cell phone connection to your cell number.
The clarity problems you're having have to do with your service provider and the signal strength you have at any given location. It has nothing to do with your throttled data connections. I only get 2G service where I live, and I've never had any problems using Google Voice for making calls.

OK, that's good to know, thanks. It's just weird that someone can call me on GV and it is all cut-out sounding, then call me right back on the regular number and it is fine (same location.)
Possible (but unlikely) GV itself is having some kinda technical problem cleanly routing your calls. But your data connection has nothing to do with it. Also could be a problem with the service of the person calling you. Make sure the issue exists with all GV calls, not just from certain people using your GV number.

Yep, ran a few tests while connected to wifi - bandwidth graph on tomato showed no real bandwidth usage during the call. Will have to figure out if my problem lies elsewhere.
