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

Hi everyone,
Is anyone having problems with the three (3G) sim in australia ?
I am currently unable to send sms and cant access the settings -> personal -> phone -> voice mail and sms settings. Is there a third party program that can fix this issue ? or some sort of a registry hack ?
Also everytime i soft-reset the xda sometimes it tends to be very long before a carrier can be detected (contracted with vodafone). Sometimes its only a matter of seconds but sometimes it can take up to 5 min without signal. Im guessing its jus a roaming issue, but has anyone come up with a way of solving this ?
Any help is appreciated ..
Cheers guys
Just interested, your ID says Optus, you say you have vodafone sim in your XDA II and your also are on a 3G network.
sorry ... maybe i should've been more clear ....
currently I have 2 numbers 1 optus and I got a new Three sim. I use the Three sim in my xda now but since the xda does not support 3G network, instead on being on the Three network, they will put me on the vodafone network as Three have a roaming contract with them. (so disregard the whole optus thing).
Three have their own 3G network in Australia but when out of coverage, they will use the more extensively covered vodafone (GSM) network.
I dont think roaming will cause problems with sms :evil:
but anyway ... thats my main problem atm. I can put up with the delayed carrier signal upon reset but the sms is a real pain.
does that make more sense ??
Hi, there I just received my XDA EXEC for UK, Im in USA.
I have Cingular Wireless(AT&T Wireless), and what I did was put the Sim card on the phone and the phone starts working, but I'm having 2 problems.
First my phone has the roaming signal all the time, I don't know if there is any way to modify that.
And the second and most important is that the phone has really low signal.
I want to know if someone can help me.
Thanks.

Hard reset the phone and choose Copoorate mode (the code is 0506). This will stop the roaming issue. Other modes load O2 customisation.
I already has my phone in corporate mode and still the roaming signal.
Thanks.

If in roaming then it would suggest that the phone has been setup with UK O2 as the default network. Have a look at Settings/connections perhaps you can change the defualt network to Cingular or try installating the Cingular CAB file from: http://www.howardforums.com/showthread.php?t=787912&highlight=cingular+cab
I have no idea what I'm saying here, but try to lock it onto GSM instead of WCDMA and it should be better.
If there is anyone who owns a dopod 838 I need help. I need to know if GSMbeam works when you are using an ordinary gsm sim in your dopod. I don't care if the dopod is doing the sending or receiving, just that you are on a normal gsm network. I can't test myself because since I bough my 838, I transfered my number. Until I buy a new prepaid gsm sim I am stuck.
Give us a call.
SecureGSM see my pm. You must have encounted this problem. I have called three and tried to varify if they support umts csd but I am less than confident the modem support tech guy even knows what I am talking about. He said it is not supported but only after I sloooooowly explained what it is. The thing that bothers me is that my remaining gsm sim gives unreachable from the dopod in the same time as the 3g one. It should take a bit longer. I think the dopod is not realy doing anything when I use LINEMEDIAMODE_DATAMODEM. I have tried to use a plian LINEMEDIAMODE_INTERACTIVEVOICE call and that dose get through, I then do lineSetMediaMode(hCall,LINEMEDIAMODE_DATAMODEM) with both ends before using the call but it makes no difference as it is not supported.
Without LINEMEDIAMODE_DATAMODEM no negotiation takes place and even though on the sending side write attempts return success it dose not work.
CSD is not supported by carriers on 3G networks.
Please see for details:

Thanks for that cab, impressive. It is much better seeing the manual band options! The problem may well be with the 3g provider but I suspect that my regular gsm functionality is also not working on my dopod. In a few hours I will have another gsm sim and I will use the manual settings with that sim to test.
Using the cab from SecureGSM it is now possible to configure my dopod to work correctly with GSMbeam. I did vodafone to vodafone and it was smooth. I was also able to configure my 3g provider to put me into roaming mode using gsm bands but unfortunately no data call (csd) would go through. The bands tab did however disapear after resetting a few times and the cab needed to be reapplied.
next step- find how to use dual sim, setup call forwarding from my 3g number to my gsm number.
Thanks again SecureGSM!
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...
Hallo,
I have a world-wide gsm version of the htc Hermes. The device is simlock-free and always has been. I put the official, albeit leaked, WM6 rom on it and it works great. But: last week I switched providers (for better data plans) and here is the result:
Data connection works just fine
SMS works just fine
But, I can hardly make calls and I don't receive any. The problem is not the network, because I switched phones (I put my SIM in a €26 SamSung phone which I use when I go camping) and I receive all of the calls. When someone calls me, they hear silence for about 30 seconds and then end up with my voicemail.
Any ideas as how to solve this? Both my old and new carrier are GSM. The only difference between them is that my old carrier (Belgium, Proximus) uses has a 3G/HSPDA network whereas my new carrier (Belgium, MObile Vikings; uses the network of BASE) has an EDGE network. Both operate on Dual Band.
EDIT: Would a radio upgrade do any good? If so, any suggestion for a radio version?
Thank you!
Come on, 80 views and no reply. Someone must have had an idea!
I did a radio upgrade (1.48-> 1.50) but that didn't solve the problem. Any other ideas?
I have TyTN and similar problem. Installed WM6, and worked fine for a 6 months. Few days ago problem (Strange?) started. I have GSM signal, I can make calls, I can receive calls from fixed lines and other GSM operators, but I can't receive calls from users of my domestic network?!? They get info Connection error? Please, HELP.
Also, when I ask request service for Call Barring I get info "Can't read specified service..."
Change the Sim
Long shot but have either of you thought to get a new sim from your current provider (port your number across if necessary) and see if that works?

I've changed SIM card, it's still same problem! But, with a SIM card of other mobile operators I have no problem.

Sounds like a problem that's related to the network provider you are using. Have you chased down their technical dept for help? All else fails, move providers.
Once had a problem where I could not get mobile signals at home but could everywhere else. Turned out my service provider had issues with broadcasts to the cell near me.
They fixed it and gave me my charges back equal to the time the system had been out.
Good luck with it.
