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 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:

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).

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.
Has anyone found a way to use Cellular Data while on a phone call? (Verizon V30 without being on WiFi) I've found posts saying that turning off the Advanced Calling feature does get you 1X data service, which it does, but what about getting full 4G working? Anyone have similar experiences?
Thanks
I've never understood this.
I've been on calls and had emails come in. I've been on calls while using my hotspot with no issues.
So what am I missing?
I just tested mine, on a regular 4G connection here at work. Was able to dial into my VM and listen to all the playback, and then go play around on data as normal. Not sure what the issue might be going on. I haven't changed any call settings (other than enabled wifi calling at home).
I'm having issues with voice calls on my Verizon Pixel 6. I live in a wooded area with not great 5G/LTE reception and rely heavily on WiFi calling as such. I had no issues with my P4xl. After upgrading to the P6, I am having constant issues when I receive or make a voice call to a friend or family member.
Their voice becomes echoed and incomprehensible. Sounds like you are talking to a robot.
The only workaround I've found so far is to disable the WiFi manually in the settings while you are on a call. Then I am on the network (either 5G or LTE) with not great reception - one bar.
I have a feeling it is an issue between the WiFi calling hand off and the network. I've tried adjusting the setting in the developer options turning off Mobile Data Always Active. No luck.
Also changed my WiFi preferences to Use Device MAC and that did not help either.
I'm concerned because if someone else needed to use my phone in an emergency, they would run the risk of not being able to make a clear and successful call.
Any help appreciated!
