Vodafone HSDPA 3.5G problem in Athena...

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?

HSDPA
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)???

I have tested on 3 Hong Kong using 3.5G, I was downloading a 6M file using ftp client and the transfer rate > 100kByte/s (so it must be using HSDPA) and the indicator shows "H" instead of "3G", I made a call from my other phone and it rings! So i guess it's the Vodafone problem instead of U1000.

yes i am guessing the same too.......thanks for your help, now we just need one more Vodafone UK user to confirm this.

slightly ot but I wonder is vodafones issue simliar using the three (uk or ie) networks?
ANyone using Advantage or similar model with the three HSDPA network?
it would certainly give me food for thought before my purchase..

i doubt Vodafone is the only one, basically is to do with their network hardware and protocol, if other company uses the same, you will be in the same situation with me. I have heard member here report that some operation in Asia and Europe acting the same, so once again, it's not just Vodafone (i think).

Same problem with Three in Sweden...
and I´m pretty sure that they are using Ericsson equipment here. Anyone else in Sweden with the same problem?

I have a Hermes through Vodafone and recently flashed with AKU 3.31 so can tell when I am connected via HSDPA. I am using FlexMail 2007 and I have been having the same problem that you describe. Some of my incoming calls go straight to voicemail, paricularly since with the IMAP IDLE function on FlexMail is frequently connecting. When I try to make calls I end up having to close FlexMail before making a call. By coincidence, I just contacted T-Mobile yesterday, and I found two other reasons for switching: 1) Web 'n Walk -- up to 1GB per month under their fair usage policy, the closest I have found to unlimited data in the UK and at a very reasonable price, and 2) Business One Plan which allows you to use your inclusive minutes for calls to North America and Europe for no extra charge. The only downside that I can see with switching to T-Mobile is that sms bundles are separate, while with Vodafone they are included in the data packages, and I will lose access to Vodafone Text Centre, which allows me to send sms messages from my computer within Outlook over the internet (and interestingly counts these as sms messages sent from the UK no matter what country I am in, so all messages I send using this are included in my bundle).

I can now confirm now at least all Vodafone UK customer will have this problem when they connect to HSDPA, i have cancell my contract with them, i pay my remaining contract fee which is £320 ! I wrote a 3 page long letter to them explaining this to them, the reason of my cancellation is because their network issue, not mine. I have phone them a lot of times as well, the answer i got is "don't use 3G then, just use GPRS!".
Anyway, i am now on T-mobile network, and the above problem is no longer here, i connect to HSDPA, if calls comes in, the network will drop itself to 3G for me to answer the phone, then up again to HSDPA once the call is finish, sweet!

Glad you got it sorted Wu & welcome to the T-Mob club.

How do i use HSDPA?
I get GPRS/3G as options in the connections box...
I only ever see 3G in the icon at the top.
Im on t-Mobile UK

Incoming calls go to voicemail with active data connection

I've got a T-mobile UK touch plus.
Currently, if I am using the data connection then all incoming voice calls are being sent to voicemail. This occurs with a GSM connection, which is part of the spec and is fine, but also with the 3G connection, which should allow the incoming voice call through. I have spoken to t-mobile and they acknowledge this problem and say they are working to fix it.
Is it likely there will be a fix for this? Is there a radio ROM already available that fixes the issue?
Sorry if this has already been covered - I searched with a pretty wide variety of terms and didn't find anything conclusive.

I have the same phone, same network... and it still rings while i have the "3g connected" symbol (3g with two arrows pointing left and right) showing.
Havent tried while connected to GPRS cuz im not sure how to force it into G mode while im near a phone.

Sorry, I should have been clearer - the phone will ring with an unused 3G connection, but not when data is actually being sent/received. This is the behaviour you would expect from GSM, but the 3G spec should allow voice calls through regardless of data - my Vodafone v1605 has no problem with this. T-mobile say it is the device not the network, I just wonder how likely I am to get a fix for this? It could be a problem with activesync using the data connection quite frequently.
A good way to test it is with google maps, or something that will maintain a constant connection, then call your phone. 3G should put the call through, but it will be rejected to voicemail instead.
FYI to put into GSM mode;
Settings>Phone>Band>Set top option to GSM, leave bottom on Auto

same problem here. but i only expreienced that randomly
i know that gprs can not handle data and voice. but 3g should, right?

Yes, 3G should be able to run voice and data streams simultaneously without any problems. I'm surprised there is not more interest in this because it seems to be a pretty major problem with the device if you cannot receive calls while browsing or otherwise using the data connection.

Me too
I experienced this too. I have an direct HTC Touch dual rather than the t-mobile branded version but I'm using a t-mobile sim. I use Exchange Activesync and am missing calls all the time.

fwiw, i experience the same with a Nokia e61 on 3-AT network with exchange active.

It seems that T-mobile have fixed their network today to allow calls while using data. Bonus.

surf and talk

is there anyway or any application that is out there that will let you browse the web and talk om the phone at the same time?

If you have GSM then you can do that without any special app. If you have CDMA then you can't do that unless you're connected via wifi.

Yup wifi and phone works really well LOL...

you can do this with t mobile???? I know att just came out with this on their network i dont believe this is possible with t mobile

Just came out? AFAIK 3G on AT&T's network thats one of the benefits. I believe all 3G smartphones that had web browsing had voice capabilities at the same time... that's part of what 3G on a GSM network creates.

You can talk and surf in AT&T 3G network for sure. I am not sure if it works on T-mobile though. I would think it should, as it looks like it depends on technology and not the network itself!

Yea you can do this only with 3G connection. Cuz you are using E to talk I would assume! And 3G for data...

this is only possible using a GSM network(at&t, t-mobile...etc) without using wifi.
3g makes no difference in this situation.Verizon & Sprint run on CDMA networks and is not possible to "talk & surf" at the same time

Well the commercial is a response commercial to Verizon's ads... so at least in this case they aren't full of crap. Verizon's 3G network is based on EV-DO Rev A. You get the speeds of a 3G GSM connection but you don't get the simul voice/data functionality.

AT&T does not support browse/talk on its Edge network. So if your phone steps down to an Edge connection you lose that ability. AFAIK Edge CAN support the functionality its just that AT&T doesn't support it.

I will check on verizon when I get a chance, but if you look in the Kaiser forum, I showed everyone there in a thread how to get this functionality b'c the carriers (US) usually strip it out to preserve bandwidth. It has to do with the RIL settings in your provisioning xml. beeen a few years, but it is there if you want to dig. Look in kaiser rom development. Also, it has to be cooked in. the provisioning registry changes will always revert back to OEM settings if not cooked in.

It is not a matter of carrier but a matter of technology. Edge and 3G are akin to narrowband and broadband for landlines. Just like you can't talk and surf the web and talk on the phone on dialup but can on DSL. It's simply a matter of bandwidth.

To explain this in a more simple matter, 3g is essentially a CDMA connection. Being that CDMA carriers use said transmission for voice, they cannot use data and voice simultaneously. However, with t-mobile and at&t, voice is transmitted over the GSM radio and a 2nd radio is present which carries the CDMA 3g technology. If said GSM device looses that 3g service and falls back to edge or gprs, the simultaneous voice and data becomes inoperable. The key part to this is that a 2nd radio transmission takes place to allow the simultaneous transmission of both services. I have often wondered, however, why other carriers like sprint and Verizon don't incorporate a 2nd radio in their devices to simultaneously connect two CDMA transmissions similar to how a TIVO/DVR box works with cable/satellite services to allow the viewing of one channel while recording another. This functionality would allow them to compete with the GSM carriers.

cdma gsm
I know that when I used to work for ATTWS (long time ago), they were freaking out about the new carriers rolling in with CDMA (some with hybrid AMPS and D-AMPS 850 mhz spectrum) because, in theory CDMA should wax TDMA's call load significantly. TDMA, at that time could only hold 3 calls per channel. So about (here comes a geeky number) every 6.67 ms the calls on the channel would switch functions. Only one could TX, one could RX, and the other was Idle.... this was all transparent to the caller of course.. CDMA rolls around with the theory that becasue it's data piggy backed on the channel, it would increase their call handling ability 10 fold. Unfortunately theory didn't work out to real work practicality b/c the new PCS CDMA carriers really had about the same call capacity as everyone else.
Now, I've always touted VZW speeds here in my market bc TMO didn't even have 3g here till like 6 months to a year ago.. .and AT&T's 3G was laugable here in Jacksonville...might as well have kept the E or G icons on the phone for as slow as things ran.... HSDPA and UMTS could put a cramp on VZWs claim to speed...as long as they can get it consistent nationwide... I'd be tempted to leave for the right data speeds.....but for now, I'm in love with my overpriced VZW plan because of the coverage, quality, and speed..... who knows what tomorrow will bring.
Sorry for the long post, but it takes a bit to explain it.. (even though most of you know it.)
Thanks,
Nate

Yes my phone shows H when I'm trying to surf and talk. I think since I have a cooked rom, it may have altered my stock internet configuration and proxy settings or something and now it doesnt work.....idunno......thats my guess. Hoping one of you guys have the answer.

Thats definitely the problem make sure proxy is off and your connections setting are going to the MEdiaNet server and that should fix it.

Why no voice and data?

I was on the Phone with Dell trying to order my new Sony Bravia TV and I was trying to use the internet so I could give the rep the proper item number. To my surprise I couldnt surf the web and do voice at the same time. I thought on GSM network this was possible. When I had Cingular a few years back this was possible. What gives? Why am I not about to do both at the same time?

That's strange. I've been on the phone and surfed the internet and/or used most of the other functions on the phone at the same time.

I've had no problems talking and surfing at the same time provided I had a 3G signal. Maybe you were in a marginal reception area and the signal wasn't solid but it does work.

I dont know why it didnt work, and it sorta pissed me off, does it have to be 3g in order to do voice and data

Was data working otherwise in that area? I've been in some areas where data doesn't work at all.

it should have been.

On edge I can't get consistant voice and data with any phone I've ever had, it is more consistant when getting a 3G signal.

You need a 3G signal to do Voice + Data as 2G (G)PRS nor 2.5G (E)DGE have enough bandwidth to support both.

Can't receive calls randomly

Recently my s7 edge appears turned off when people try to call me. Then after a while i get the text saying someone tried to call me but the phone was off (but it was actually on). No problem making calls. It's not that you can represent it, it is totally random and not too frequent but enough to annoy me.

This used to happen to me too, i think it was because of carrier and coverage, especially when 4G signal is low.
What i found helpful is keeping my device on 2G only when on Wi-Fi or don't need high speed cellular data.
I use this app to have a shortcut of 2G/3G/4G switch in notification panel, makes switching between 2G and 4G easier.

Thing is i NEVER use mobile data, it is off all the time and the apn list is empty (no profiles), i only connect using wifi. Does that still have an effect ?
I hope it is a coverage problem

It doesn't matter if you never use data, device can still connect to 3G or 4G (though in some cases an APN may be needed to connect to 4G, that depends on carrier). In your case, since you never use cellular data, you can safely set your device to 2G only. With 2G you will have better signal for sure, and it's less likely to have missed incoming calls.

Recently my s7 edge appears turned off when people try to call me. Then after a while i get the text saying someone tried to call me but the phone was off (but it was actually on). No problem making calls. It's not that you can represent it, it is totally random and not too frequent but enough to annoy me.

Does anybody know if this is a hardware problem? a bug ,or is it the carriers fault :fingers-crossed:

I've had the same problem with a Galaxy J7 2015 also bought in the UAE.
Again not too often but enough to be annoying. I found that selecting 2G/3G without LTE improved the situation.
