I just switch to 3G instead of 2G. I want to experience the high speed internet suffing via my handset.
But I found the problem is that the phone call can't came in if I using the 3G data. Not even transfer to security services. Just a "Busy tone".
Check with the service provider and they are now checking with their technical dept to see if they can found the problem.
They said that the call should be able to come in because the phone call channel is different to the data channel. :roll: :?:
Anyone experience the same problem?
I experienced the same problem with my CHT9000. You may change the setting to GSM then call can come in when you using GPRS but you can't enjoy the high 3G speed on data transmittion. Anyone has better solution?
complicated issue; can be the same with GPRS/EDGE ; I made a lot of research read below;
http://forum.xda-developers.com/viewtopic.php?t=54738&highlight=
It is interesting. I don't have this kind of problem while I am using GPRS. But it happen to my new network provider (3G).
Lucky you then :lol:
At least you have GPRS/EDGE working and as a result it is absolutely a network provider issue.
I talked every detail with a guy in my Net. Op. and seems can be solved by "tricky switching something on" but they could not make me believe that this is not thier mistake. Because Class B phones MUST suspend the data flow and accept incoming calls for the technical point, only class A phones (no retail ATM) can make data flow and GSM talk at the same same.
GPRS is 2G, EDGE is 2,5G and same tecnique as 3G, only speeds are lower, so I beleive if u use 2G suspend while incoming calls your Net.Op. can solve the problem if they want :wink:
I have this strange problem with my vario II.
I am using Tmobile GPRS on both 2g and 3g network, If I am using the 2g phone works if If am using 3g phone doesn't work if I call it, the phone rings but doesn't alert me. The most annoying problem I am having is the phone switches between 2G and 3G if I am in a call the phone goes silent can't hear anything the display shows the call as connected and around 5-10 seconds later the phone drops call drops. This happens even if the data connection if not active.
What is the deal with that? anyone else have this problem.
Phone band settings are below
network type
Auto
GSM
GSM(900+1800)+UTMS(2100)
I've just discovered the same problem with my orange branded tytn, I'll be phoning them later to ask what they can do about it.

Works perfectly on T-Mobile UMTS for me. I did flash the Dopod 838Pro ROM though.
will flash the dopod rom in the morning. I am currently using the imate rom, and the tmobile rom the device shipped with had to many slow downs so it had to go. if this fixes the drop out issue I will be happy if not the phone will be in its box till a rom update. got the phone cheap so don't really mind. nice phone/pda apart from this issue in my line of work can't afford to miss or drop calls.
so is this a hardware or a software issue then?
No harware problem, it is absolutely software issue. Read my posts above and the links I gave
No problems here I'm afraid.
Voda v1605 running the Voda Blackberry Client, so either 3G or GPRS (where no 3G available) on all the time. Calls and SMS received perfectly.
Only issue I have is when using 3G, unlike home wired broadband, I cannot use multiple applications through the single 3G connection (e.g. Blackberry client on and surf too)

Hello,
I have a DOPOD D810 and using with Vodafone-SP. When I have the 3G on the calls least about 11 seconds (sometimes 9 seconds) and without 3G (the old GPRS) the phone calls work perfectly.
Anyone had the same problem or know why it's happening?
sometimes, when iam connected with pc (usb) and share internet connection to it. i dont try it with gprs.
but when i have 3g connection without pc, works perfect
Is HSDPA in your region? Because i think i have read some posts where the HSDPA implementation makes that problem. Just turn off HSDPA support and see if its ok.
i dont know, but icons switching between 3g and H
i'm having the same problem too. The calls will drop in less than 10secs in 3G mode but with normal calls. Checked with the network provider and the Dopod HQ. Network provide says it could be the hardware problem and the Dopod HQ says it could be the network problem.... this is making me sick. And some Expert says this is normal to PDA's 3.5G phone.
Basically I can say that depends of the cell, I mean, sometimes 3G calls works fine and sometimes not, usually the ones who doesn't work fine are in different 3G cell (becasue I'm in different location).
So, can be both, a network problem (some software or hardware in the cell antena) and the phone (who don't 'talk' with the cell properly).
I search and a lot of spanish Vodafone users (Trinity) have the same problem.
just noticed that after softreset the 3G signal becomes perfect and calls signal will stay strong. But after i awhile without making calls out or incoming calls. Then the nightmare happens again. Checked with the Dopod hardware HQ, they says if the 3G signals drops then the GSM will drops too. So, it couldn't be the hardware unit problem.
I am having a strange problem.
As soon as I start a call all data connections (including Wifi) are dropped.
They automatically come back after the call is ended.
Has anyone else experienced this?
Is this something that can be fixed?
Thanks in advance for all the help.
I have had this happen to me only when connected to edge. While on 3g the connection stays.

data connections are always dropped during calls, but wifi shouldnt drop. I have never had the wifi shutoff while i was making a call....strange

the point of 3G is that the connections will not drop.
Thanks for all the info.
I tested the Wifi again and that did work.
I don't live in a 3G market. So i guess i'll have to wait.
it only comes down to the equipment of the gsm network operator
i never loose data connection with any of my phones be it
gprs or 3g
but if the network operators central equipment dont support it
it dont matter what protocol
I actually lose 3g when in a phone call...Emails, Txt's and other stuff does not come though. On my blackberry, txt will still come through while in a call. Its wierd, I have full 3g reception and I cannot browse through 3g while in a call or recieve any txt.
Hi everyone,
I'm on a fringe coverage area with AT&T. I have a pretty new sim card, but I noticed that I get a lot of dropped calls while on 3G (or H). I usually get 1-2 bars on 3G. Shouldn't the call I'm on, hand-off to Edge if the signal is not strong enough on 3G? Right now, its dropping the call altogether on 3G with no fallback to Edge. Is the Xperia's radio to blame for this?
Thanks!
i dont know who is to blame but if your on the fringe as you say, you should just manually set your device to use edge/gsm.
it will save on your battery and have less dropped calls. otherwise, you phone will keep bouncing between signals.
i also have the same problem and i am curious of the answer i dont want to lose 3g all together but i have 1 bar in my house and drop calls also.
Has anyone on AT&T tried to flash their xperia with the Raphael radio? Is the signal alot better?
not just exactly the same problem here, but similar (according to the network). at home, i have no 3g coverage and manage to get edge at best, problem is intermitantly my voice stops, even though i can here the other caller perfectly, the phone still keeps between 2-3 bars of signal, and i can even stay on the call over 30 seconds after it happens. the other caller can just hear like a dead noise. the network has me testing the 3g thing for the next couple of days though.
PS. this also happened with a K850i and a K800i
Hi,
Was wondering if anyone got bad reception with their phone. I tried 3 different carriers since I had my ideos, in neither of them I ever had very reliable reception and lately the problem is getting worse. I'm running aurora 4.1a and I loose reception all the time, and the battery drains so quick because it's always looking and looking. My sister, my mum and my dad all have good reception (2 of them with my old carrier and 1 with my current carrier).. I can put my dad's phone (same carrier) next to mine.. he will have full bars with 3g and I'll have no reception at all!!!!!! Then it connects and disconnects again, and so it goes... Anyone having such issues?
Thanks.

I'm having the same problem, I'm running Aurora ICS. I use to always have good reception everywhere, Then suddenly I've just been unable to. Any help would be great! If I do find out any fixes to the issue myself I will sure let you know.
Good to know that I'm not the only one! Thanks. Hope we find a fix soon.
I've fixed mine now, What I've done is I've gone into Settings > Wireless & Network > Mobile Networks, and scrolled all the way to the bottom, and simply re-registered on the network and selected Use only 2G Data. Mines now working fine with full connection everywhere. However I don't know if our problems are exactly the same, however this is what fixed mine. Sorry if this doesn't help.
I have the same issue. Mine connects to 3G and has good connection, but then it simply disconnects and moves to 2G or reconnects to 3G some time later. That happens pretty frequently and I thought it was an issue with the carrier, but now I am not sure anymore.
Blefish, that is EXACTLY what happens to me, and I tried 3 major carriers in Australia (the only 3 that have their own actual towers). Just after I posted this thread, I happened to do the same thing as IwAsBlack recommended and... so far it seems to work. I have generally better connection and I haven't seen that ugly no reception icon since! Of course, internet browsing will be generally a bit slower but then again, it's better than staring at the phone for 3 minutes until it reconnects just to open Google.
You haven't stated which model you have. I got rid of a Motorola Bravo for at U8800-51 and I have excellent performance over AT&T (US). Crystal clear even with only one bar and I have never had a dropped call.
Have the same issue on any ROM with any mobile network in Belarus. Can't use 2G as recommended above 'cos of a huge use of mobile internet for some net-radio.
Sorry for bad Eng.
Its a U8800 Q&A forum, I didn't think that I had to state the version since I have a U8800.
Yesterday I tested and kept an eye on for the whole day! The reception since changing to 2G only has been AWESOME! Only had a drop out when I was in the subway (of course!) but aisde from that, I had amazing reception not to mention.. that my phone lasted the whole day with still 15% left!! (3G on, it would have to charge it twice while I'm at work) So, it fixed my reception AND my battery problems.

FYI, Ideos X5 U8800 describes four different models.
I know it does. What I meant is that I have the Normal U8800 model, so I didn't feel like it was necessary for me to point any variant model number like PRO or 51 or H, because it's STANDARD U8800
So we can make a conclusion that U8800 does not operate well on 3G. I can't switch it myself because I want to use internet too. And I am pretty sure we can't do anything about it, no matter if the problem is in hardware or software.

Mate, if you switch to 2G you will still be able to browse the internet! It will only be a LITTLE bit slower, better than having constant disconnection!!! I constantly use the internet to sync my gmail, send free texts, browse the net and a bunch of other stuff.. works even better on 2G with constant reception, not to mention the benefit of the phone battery lasting a whole day (AND still have internet).. so switch to 2G and you will like it... still good internet only with better reception
Same issue
Having same issue when using GSM/WCDMA auto or preferred modes. works normal on GSM network only.
Even when I have no signal of 3g, gsm is working in the background.
problem arises when I have a call, 3g signal drops to minmimun, after the call phone tries to reconnect with the 3g signal but drops the GSM signal in the process.
Try this , as soon as you disconnect the call, try to call yourself from other at that instant only. Your phone will be shown unreachable because phone drops the GSM signals.
