During the past several months I've tried several WM6 ROMs - mostly PDAViet's. Currently I have the following:
ROM version: 7.7.7.7 WWE
ROM Date: 9/08/07
Radio version: 1_02.20.21
Protocol Version 4.1.13.9
ExtROM version: Mystrerious 1.0
The device is Imate's Jamin (Prophet G3). Since I started to use WM6, I am often having the problem when I cannot receive the incoming calls from time to time - my friends have to leave the voice messages in my mailbox even when my phone is on and the cell coverage is great. It seems that it is related to GPRS activity - I have GPRS/EDGE internet connection always on and I have my email synchronized with an Exchange server over the air. What is even worse, I have no way of knowing if someone has called me - even if they leave a voice message I am getting no notification on the PDA. I started to call my own cell number often trying to understand the pattern and I noticed that when I cannot get through, I can disable the GPRS and after that the call gets through.
I don't remember having such problems with original WM5 ROM when I purchased my Prophet, so I assume it is related to WM6.
As I said, I tried different ROMs and different RadioROMs (now I rolled back to the original RadioROM originally provided by Imate, since I saw no improvement with newer RadioROMs).
I have T-Mobile USA mobile service with Total Internet plan if it makes any difference...
The questions:
is anyone else experiencing problems like this? any workarounds?
is phone line is supposed to work simultaneously with GPRS? Could it be caused by a difference between [GPRS simply connected and no internet activity] and [GPRS connected and sending/receiving data]?
could it be related to the settings of activesync (how often it syncs with Exchange or be continuously connected)?
Any help is greatly appreciated...
Incase there is any data transfer happening at the time of the call coming in (pls note even while polling there is some data being transfered) the call will not go thru.
I have been using WM6 roms for the past six months... from my signature you can see how many i have treid, in each of the roms.. I also use push mail, hence I am always connected thru edge....I get phone calls even when connected to GPRS.. however if there is any data transfer happening at that point in time the call goes into my voice mail.
i think it is problem of your service provider,try another radio rom?
I am having the same problem, any solutions?
It happens to my device roughly once a month, and my GPRS is always off. So IMHO it is related to WM6. It did not happened on WM5.
My gprs (edge) connection is always on and I have the same problems on the radio rom 2.41.21. Try to use the radio 2.61.21 - no problems with incoming calls...
Korand, thanks for the suggestion. I actually tried 2.61.21 a couple of months ago - it didn't fix this problem
For now, I've changed my Activesync settings so that it will sync data via GPRS every 30 mins (before it was "stay connected all the time") - hopefully it will decrease the probability of getting the incoming call at the time of data transfer.

lol... this is no problem.. this is wht is supposd to happen on GSm.. because it works on a single FM frequency n not a band like CDMA or TDMA.. this is normal.. its jus like whne ur using ur dialup internet n ur phone line gets busy.. soo no solution unless u switch to TDMA
hahahha,you don't know what are you talking about,what FM frequency,this is not Benefon Delta lol

ok.. then can u tell me the kind of modulation is used in GSM.. go wikipedia ur ass n u will see wht im talkin.. ur such a n00b
it is Gaussian minimum shift keying (GMSK).. jus a modified version of FM to use support multiple communications on a single frequency.. talk to me when u got ur engineering degree..
No calls reception - no calls outgoing
I have a TYTNII who suddently has the same problem of incoming calls directly to mailbox, for each calls, and also I can't call anymore.
Does anyone solve this problem?
With the Sim card in my Qtek 8300 WM5 I don't have the problem.
HTC support say they don't know this problem and ask to make a hard reset...
ROM 1.56.406.5 (30/8/2007)
Radio 1.27.12.32

seems then its a common problem since tytnII has it may be there is something written in registry to divert call to voicemail while data traffic is going ON to avoid bad colliding accidents of voice and data packets on the same highway
to avoid dirty signals..thats all..
btw,all i know is that GPRS+receive calls = bandwidth bottleneck...see? how "cheap" the GSM is
so,the solution is to disable one of them...
I use to have the PPC-6700(Apache) and recently switched to the PPC-6800(Titan).
Previously I was able to use voice and data at the same time. One thing I have noticed is when there is a phone call the signal drops to 1X.
I do remember there was a registry hack that allows voice and data on at the same time.
Thank-you
Not really sure how you got voice and data going at the same time when no one else can. EV-DO is data only, which means you absolutely cannot have voice and data going at the same time. If you're using data, and you get a phone call or SMS, the phone pauses the data, once the call or sms has finished, the phone unpauses the data. That's how the technology works bro. Unless you got your own towers utilizing EV-DV, I'm pretty much positive you didn't have them both working at the same time.

Who knows he could have been using a WiFi connection and talking at the same time. He was a bit vague with his comment.

It's possible, but he did point out the fact that the phone switches to 1x with a phone call, so that leads me to believe he's talking about evdo data and voice at the same time which is not possible.
I just wanted to comment on this as I have been looking for something similar and did not want to open a fresh thread. What the OP was referring to is the Apache. I had the Apache and can confirm that there was a registry hack that allowed browsing while on a phone call. I wish I can find this information to see if it applies to the mogul because it would be a great feature to have. (ie. The Wife calls "BABY!! Im totally lost, please help me, Im on the corner of Stop and One Way. 'swtiches to landscape, clicks on google maps, saves the day'"
Thanks
I thought I remember reading somewhere that a way to test if EVDO rev.A is working properly is that EVDO rev.A is supposed to support both a phone call and data at the same time.
I can't remember where I read that though and I've never got it to work.

Yeah, I do remember reading somewhere about this also. I know it shouldn't make sense, but it works. Also, we'll probably see Rev. B not too far off in the future, which will allow for VoIP over standard data connections (not WiFi)
Is anyone having a problem where calls go straight to voicemail when data is in use?
This is a serious flaw if its by design!
I'm on o2 with the latest rooted rom. Not the custom modaco one.
Well I've just found out this is a feature of 2g rather than a phone problem. You can only take calls and browse if you have 3g signal.
Maybe on O2, but I get calls coming in no matter what I am doing on my Hero with a 2G signal.
I'm on Orange.
Same on my Nokia's too.
We only have 2G at home so I know its not a 2G / 3G thing (for me at least).
Perhaps I need some different APN settings. Could someone else on o2 UK confirm whether this is a problem or not? Also if you could post your apn details?
My apologies.
You are right and i am wrong.
If browsing on 2G the call is routed to voicemail. Even if you press Home and stop browsing, the call is routed to voicemail.
It seems that only until you have tried to make an outgoing call will it kill something and accept incoming calls again.
No wonder I keep getting missed call texts from Orange.
It would appear that if the Hero is doing anything on GPRS (Weather, Mail, RSS etc) it will not accept calls.
Thats pretty crap.
My old Nokia's were not affected like this I'm sure... maybe they were and I never noticed.
if you can open a Browser window while on a call it will tell you that there is no data connection or to use WiFi.
So is this a 'feature' of the Hero or the 2G network ?
From further investigation it seems to apply to all 2g networks. I've done a bit of googling and there are a few posts about the iphone and similar issues.
I wouldn't mind if I could get a 3g signal in most places. I really hope that radio firmware gets better. Seeing as I can get 3g on o2 in a different phone at home.
Sigh, oh well... looks like people need to learn to SMS me or actually leave a message
This also explains why my TomTom used to crap out whenever I was on the phone (Nokia) sometimes... when it worked I must have been in a 3G area.
it's both phone and network dependent.
many phones do this on 2G, as there is no 2G device in the world that i am aware of that will do voice AND data at the same time.
However, due to this limitation, many networks have set up their network to forcibly terminate a data connection when a call is waiting to be routed to that phone. I don't know if it is a command that is sent to the phone that the phone has to interpret and support, or if it is simply killed from the network end.
some network/phone combos do it, some dont. it just depends on the combination of the two i think.
similar things happen on HSDPA, yet you can see the same HTC phone get forced down from HSDPA to 3G on t-mobile to accept an incoming call, but do nothing and get a voicemail on Vodafone!
Thanks for the response rhedgehog. I think if nothing else its good that people are made aware, I had no idea!
I would be interested to know whether other networks disconnect the data on the hero in order to receive calls. It would also be interesting to know whether other android handsets do the same.
My data habits have now changed. No more exchange push email - only check every 15 mins.
Hi,
Anyone aware of incoming calls not getting through, e.g. going straight to voicemail, when you're browsing the web or whatever? Or is thi to be expected?
Thanks

GPRS/EDGE will drop calls. 3G and HSDPA, to my knowledge, won't.
Maybe you were not in the 3G coverage?

Its a known issue where 2g networks cant cope with active data connections and a voice call and divert straight to voicemail. 3G doesnt with the capacity.

the problem is that I could expect this when I am actually browsing or something but most annoying is that this does happen even when the phone is on the standby not doing anything (it must be downloading some data in the background though)
and frequency with which it drops 3g and changes to 2g and back doesn't help it in anyway... connection is very very unstable...
I guess its down to sensitivity or buggy radio rom.
i have the same problem here with eplus in germany. the normal behaviour would be, that the data flow is interrupted on incoming call and the call gets routed through. after the call ends the data connection will be set to active again. this is how my WM Phone handled calls during an active data connection. there are a lot of people with similar problems in a german forum. i thought that this is a network issue but it seems that it is a htc here related issue. If so, that would be very a major issue as the android OS and hero are build for beeing online most of the time. Anybody tried a different radio version?

Its not a phone issue, its a network issue. Its to do with NOM1 and NOM2 and how the network prioritises calls/data.
The network should either send a request to the phone (only some phones can handle the request though) to terminate the data or the network should cancel it on their end first and then route the call through. Most networks don't seem to do this.
Changing radio version will not rectify this issue
but obviously there is something that has to be done because it potentially will affect ALL android devices if they use so much background data.
Seriously it cannot be acceptable that phone will simply not ring just because it was checking email or updating weather...
Hi All,
I've updated my Titan to TANGO and new firmware (and radio fw), but I have the same problem I had with Mango:
Data (internet/mail/tethering (shared internet connection) does NOT work if a phone call is on!
IE: I used tethering with my PC, if a phone call come no data connection, when I closed the call data connection restart!
This happens with EDGE and most of the times even in HSDPA... with my previous HD2 (WP6.5) I could use interner with my PC (in tethering) having a call in the same time even with EDGE...
Is this happenng to someone else?
PS: I inserted manually APN to be sure it is correct... no changes
BYE
I am having the same thing happen to, when browsing the web I cannot receive phone call.
Stock rom: OS-7.10.8107.79
Firmware- 1600.2200.20501.401
Radio-16.23.06.10_16.32.00.23U
Boot loader-2.5.160015.3(137079)
On which roms are you guys? Stock or customs?
f.
You know that it is totally normal that you can´t use data if a phone call is active ???
hi,
this happend on Mango and happens with Tango too (official HTC rom)
When I receive a phone-call, connection data gets out and NO internet connectio!. When the call finish the internet restarts again.
This do not happen on DEll Venue PRo with official Tango: internet keeps going when i speak by phone, as on my old HD2 with WM6.5
HELP!
I often use internat-sharing (tethering) and if I receive a call I can not answer if I qant to keep the internet connection!
THANKS

Hi have the opposite problem:
when browsing the web I receive a phone-call, but if I answer internet stops (under EDGE, HSDPA...) and restarts when I finisch the call
It is not possible to have both data and voice in EDGE mode. That's the limitation of GSM radio on that mode.
You need to be in 3G mode in order to do so. Old WM phones can automatically disconnection data if there is call come in and reconnect after you handup.

I preferred your your problem, (although I don't think it's a problem) I don't mine receiving phone call and losing data.

No, on my Dell Venue Pro under EDGE I can surfing web and syncronize email while I'm calling!
I do it, but I don't with my Titan
After 1000 tests with 4 sim I can say:
- on my Titan I can call and have connection only under HSDPA if I manually set APN
- on other devices (Dell Venue Pro with WP7.5 Tango + HD2 WM6.5) I can call and surf the web with EDGE 3G HSDPA
is it only on my device?
I know that EDGE is not very often present, but it happens in Italy... and in some places where I work!
PLS, if someone could make a test... thanks in advance

I don't know how your DVP does it but do a search and you will learn that it is not possible for EDGE connection to serve both voice and data. It could be that you are really connected to 3G but your DVP is reporting EDGE. Or your DVP has two separate radio, one for data, one for voice.

Thanks for your suggestions!
I searched in the web, and maybe I found out the answer from
http://www.techrepublic.com/forum/q...a-gets-disconnected-when-call-comes-on-mobile :
EDGE (and GPRS) are capable of supporting simultaneous voice and data ONLY if it is a Class C device.
Most phones these days are Class B (such as iPhone).
Class B support voice calls while in data mode (data disconnects when a call comes in) and data is "attached" while the phone is idle. Some Class B devices are configured so that the data takes priority (iPhone). Thus an iPhone will not take a call when an active edge data transfer is ongoing..it goes to voicemail.
Class A devices are either in data mode or voice mode (but never both).
even supported here:
http://reviews.cnet.com/8301-19512_7-10115034-233.html
"GPRS network 130 can be designed to operate in three network operation modes (NOM1, NOM2 and NOM3). A network operation modes of a GPRS network is indicated by a parameter in system information messages transmitted within a cell. The system information messages dictates a MS where to listen for paging messages and how signal towards the network. The network operation mode represents the capabilities of the GPRS network. In a NOM1 network, a MS can receive pages from a circuit switched domain (voice call) when engaged in a data call. The MS can suspend the data call or take both simultaneously, depending on the ability of the MS, In a NOM2 network, a MS may not received pages from a circuit switched domain when engaged in a data call, since the MS is receiving data and is not listening to a paging channel In a NOM3 network, a MS can monitor pages for a circuit switched network while received data and vise versa. "
This means that HTC Titan is not a Class C device...

Your answer here:
http://reviews.cnet.com/8301-19512_7-10115034-233.html
We previously noted that the iPhone may miss calls while sleeping (locked). Some users are now reporting what seems to be a significant issue where their iPhones cannot receive incoming calls while transferring EDGE data. Here, in a nutshell, is what appears to be happening:
The iPhone cannot simultaneously use EDGE and voice services. That is, if you are on a call, you cannot concurrently access EDGE-data functions. In addition, as documented in Knowledge Base article #305711:
"While iPhone is actively transferring data over EDGEâ??downloading a webpage, for exampleâ??you may not be able to receive calls. Incoming calls may go to voicemail."
The "may not be able to receive calls" portion stems from the fact that there are two types of EDGE network types, NOM1 and NOM2. When your iPhone is connected to a NOM1 network, the data transmission will generally be interrupted, and the incoming call allowed to come through. When your iPhone is connected to a NOM2 network, however, the EDGE data transfer process cannot be interrupted, and the call will generally go to voicemail.
Fortunately, there is a way to check whether you are connected to a NOM1 or NOM2 network. First, put your iPhone in field test mode by accessing the Phone application, tapping Keypad, then entering *3001#12345#* and pressing Call.
Tap GPRS Information and look at the entry next to nom. It will be either 1 or 2. If you see a 1, you'll likely be able to receive a call while transferring data. If you see a 2, you likely won't.
Unfortunately, it appears that NOM2 is much more prevalent on AT&T's data network. In fact, we've yet to see our iPhone connect to a NOM1 network. As such, we can't even state with certainty that the iPhone supports NOM1 at all.
"GPRS network 130 can be designed to operate in three network operation modes (NOM1, NOM2 and NOM3). A network operation modes of a GPRS network is indicated by a parameter in system information messages transmitted within a cell.

As far as I know, there isn't any class C devices on the market. Maybe your DVP is an exception but I highly doubt it.
