Vodafone HSDPA 3.5G problem in Athena...

[wu5262]

Ok guys, i need some of you to do a bit of testing for me, here is my problem:

When my 3.5G (HSDPA) Data connection is active I cannot make or recieve phone calls.Any incoming call goes straight to voicemail and any number I dial the phone will display "call ended" before it even starts to to ring. The minute I close the data connection the phone works again.

I have done a lot of searching on net and in this forum, some other member are having the same problem. But i think it's only with vodafone, T-mobile don't seems to have this problem. What T-mobile do is to disconnect the data transfer ot reduce it to only 3G while calls comes in. BUt vodafone don't do that, it receive phones ok when in 3g mode but no ok in 3.5g at all. It doesn't switch itself.

So please if you have a vodafone and Athena, try go to Internet, and make sure it's 3.5G, while data is transferring, make a phone call to yourself and see whether it gone through. Please can t-mobile user test it and confirm it does work on your device as well. Thanks

If it's vodafone's problem.....i will have a very long call with them tomorrow then

p.s. Please make sure you test it "WHILE" the data transfer is active, so e.g. open up a site in Opera, while is loading, make the phone call, i am guessing for T-mobile, it should switch from 3.5G to 3G to enable to call comes in, but for Vodafone, it won't do that and will just reject the call!!!

Thanks in advance!!!

This is the same with all 3.5G devices... Its a problem with the Vodafone HSDPA network.

I was reading about people who purchased a Nokia n95 and got a insert in their box advising that if they experiance problems with in/outbound calls to switch to 3G or GSM!

The only difference between tmob and vodafone is the hardware in the network. tmob is running Nokia HSDPA hardware/software and vodafone use erricson.

My advise it to use the bandswitch application which allows you to turn on HSDPA when needed keeping your device in gsm mode the rest of the time. It will also increase your battery life.

which application will you suggest? btw this is very very bad for me since i use emoze which is a push mail application, my connection to internet is always on, and it always runs at the highest speed (which is HSDPA). Therefore if i have this application open (must do if i want my mail to get push in), then i can't receive phone calls.......

Looks like T-mobile's one is much better in this case, wonder what they whill say when i phone up tomorrow. I think this is quite a serious problem, while you are tramsmitting data ( e.g. liveTV, liveRadio, push mail, downloading, browsing.......)the phone won't work!!!!

I will have a long discussion about this with Vodafone tomorrow and see whether they can cancel my contract......

So T-mobile one will switch itself from 3.5 G to 3G while call comes in?

Hello

I'm using at the moment 3G can someone tell me if I buy the HTC Advantage well it support HSDPA.

If it does how do I activate it do I need a new sim card or do I call Vodafone which is my service provider to activate the feature.

Thanks

your question is a bit out of the topic, anyway, of course Advantage support HSDPA, most of the sim card already 3G capable, if some reason you have the old type of sim card, then request a new one. You can tell when you connect your device which type of service you are getting. For vodafone you do not need to activate it, it's already been activate.

right, thanks for that, i have notice about this application too but don't think is much help here. Basically what i want to do is let my device automatically change from 3.5G to 3G when calls comes in, this program doesn't allow you to do that. It can manually swtich between 3G and GPRS, but not from 3.5G to 3G and not automatically as well.

So here is the situation when you will face problem, if you are using vodafone, and your device is 3.5 capable. When you are browsing on the net, or listen to live radio, or watch live TV, or do PUSH mail, of course you want it to the highest speed and it require you to have continues data transmission, so while you are doing that, you won't be able to receive any phone call at all, it will all goes into your voice message. HENCE you will miss a lot of calls !

From how i see it, this issue is big. And big enough for me to have a long chat with Vodafone and possibility change to T-mobile.

So before i do that, i need to make sure three things, for vodafone user, do you have the same problem? and for t-mobile user, do you NOT have this problem. Is there any ways to fix this?

My contract cancellation fee is about £350 so i need to make sure T-mobile one works before i go ahead, thanks for the help guys.

Hey Wu.

I'm with T-Mob and whilst I can receive and make calls whilst surfing or downloading (so presumably Push e-mail aswell), it is not always as reliable as I would like it to be.

It does work and generally allows simultaneous voice and data transmission, but for some reason it sometimes (only on occasion) will 'pause' the internet/data transmission (specifically download) and break the data connection to allow voice calls but automatically resume the data connection straight after the call.

It's a bit confusing sometimes....but that could be due to not knowing whether I'm on HSDPA or 3G at the time?!?

In any event, it does support the two simultaneously and switching is definitely automatic.

I'd go the T-Mobile route if I were you, If the switch is not too costly for you.

well, switch is very costly......£350. Once thing you need to make sure is whether you are on HSDPA or 3G, because in 3G, you can have voice and data at the same time with no problem, but in HSDPA, you can't, but even that, the best solution (i think it's the T-mobile solution) is when calls comes in, drop the data speed to 3G to allow calls to comes in, once calls finish, bring up the speed to HSDPA, this case you don't miss any calls. Apparently, this isn't the Vodafone way, for Vodafone, if you are on HSDPA, the system simply don't do anything therefore you miss all your calls.....

Today i have been testing push mail, looks like Microsoft knows this issue too so whey they only boost up to HSDPA when checking mail with server, once it's finish, it's drop to 3G again. So direct push is ok.

But there are some other third party software (most of them!!) which doesn't do this, therefore you will just simply miss the call.

e.g. If you are browsing internet, while the internet is loading, you will just miss all your calls.

I kind of need someone with vodafone to confirm this behavior, but i am 80% sure i am correct, therefore i will call them up tomorrow and see what they say.

Wich part of Vodafone has got HSDPA??? I thought it's standart UMTS (384kbps)???
