call can't come in while data always on

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;

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)

11 seconds with 3G

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.

Dropping calls

Does anybody else have a problem on o2? For the past few days my HD has been very flakey.
o2 are usually spot on in my area, the phone has good signal and what is happening most of the time is ill take a call then after 20-60seconds it will cut off and play the "duur duur" noise.
Is there anything i can further do to trouble shoot this problem and see if its a phone or possible network problem?

same to me
It happens to me too, but in Serbia, with Telekom network operator. So it is regardless of the network. Only thing that comes to my mind is connection setup update that I have recently did. Found out that call is dropping when I change network station cell or type of connection (from gprs to edge or 3G)
I tried to make new connection setup, will report with findings...

[Q] Omnia 7 data connection problem

Hi, since I got this phone and I've been having problem with the data connection, wifi is working fine, but 3G is not, it shows the 3G symbol but keep switching to H symbol and back again to 3G constantly, i never been able to surf the web or do anything online on 3g connection since i got it.
I tried putting in the setting from my provider and got the samsung network app thingy but nothing helped, even after updating to NoDo.
This is really bothering me i cant enjoy the phone when im outdoors, i switched back to my iPhone 3gs temporarily.
I really hope this can be solved.
I'm thinking if there is some way to make the phone only works on 3G and turn the H off.

H is for HSDPA and is far more faster than 3G. I reckon you run ADC on startup using samsung tools and hopefully the problems with connection will be resolved. Alternatively contact your sim provider for network configurations.

Here it also switches between H and 3G, or well it did on my other wp7 phone my (european) omnia uses 3g+. That's normal; the H mode probably eats your battery alive, and it only switches to it when your data connection is active (i.e. data is being transferred)
Your problem appears to be an Access Point problem, you can configure one yourself at the mobile connection settings page. (bottom). Check the web for the settings you'll need.
You see most phones are configured automatically by their providers, but the omnia probably isn't supported.
Hope this helps

the APN for China Unicon is "3gnet"
just add it your 3g connection will work.

Data connection loss (on Tele2) hangs on H+

Hi all.
I’m experiencing a problem with my dataconnection which renders my data connection almost unusable.
Hope someone can point me in the right direction!
The situation, I am using a Oneplus 6T with 2 sim-cards. One for calls one for data. The sim I use for data loses the connection multiple times while commuting to work (train).
It happens on the same locations so I assume it has to do with switching between towers. The connections completly drops to no signal (the other card still has a signal).
After the connection drop one of the following happens:
- Reconnect to 4G after a few secons to minute(s)
- Reconnects to H+ and stays connected to H+ until I switch aiplane mode on and off). Even when getting of the train and waiting on the same spot it hangs on H+ until I use airplane mode.
What did I already try.
- New SIM card from provider (Tele2)
- Complete profile reset by provider and check of APN settings
- Tried both SIM slots
- Tried the SIM card in another telephone (connection does not completely drop)
- Use another provider (T-Mobile) with this phone. The data connections seems to work fine on T-Mobile.
So it looks like a combination between Tele2 and the Oneplus.
(By the way Tele2 falls back to h+ and 3g from T-mobile if they can't provide 4G)
Thanks for reading and all tips and tricks.
