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)???

quite a lot of places got HSDPA already, most of the London at least, i did a speed test yesterday and i am getting 1.3Mbps (1300kbps). very fast indeed but useless if we keep missing calls......

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 only ever see 3G in the icon at the top.

Is there a way to use minutes from your plan in exchange for internet access on PPC?

As the title says...can this be done?

Wouldn't that be nice. I have mad rollover on my AT&T account (close to 10,000 minutes).

www.nocharge.com

you can set up a dialup (pre-GPRS) cellular connection which would charge you by the minute as opposed to by mb. This is however very slow and not particularly reliable. Data is so cheap these days that you might be better off changing your plan if you happen to be with a provider that offers rubbish data plans.
As regards your rollover minutes - well that's just a bummer really - maybe you chose too high a price plan for your needs.

You can use CSD, which was how "wireless data" was handled prior to GPRS. Technically, CSD is 1G (while GPRS is 2G, EDGE is 2.5G, and UMTS is 3G), so it is SLOW (something like 2.6kbps I think).
CSD uses your plans minutes to dial out. Not all carriers support this anymore, so I would call CS for your carrier to double check first.

Uk Vodafone customer can surf in Hsdpa but can't connect to G

Hi All,
As UK Vodafone CS were no help what so ever...I thought I would ask the experts.
I recently updated my phone via Sony Update software to
R3AA013
At home all seemed fine I created a new wap and connection and setup email etc and on the 'H' network all was fine.
Unfortunately at work I have a weak signal and only ever get G. Problem is now the phone seems to be unable to connect to this, just seems to cycle through attempts then gives up.
Is it best to reapply the firmware update and start again or are there any settings I can check first?
As I say in the HSDPA signal is seems to work fine...
Thanks in advance!
Paul.

Personally i have only got a 3G signal in Crystal Palace but no where else - i sometimes see H but that is always a very low signal and sometimes G with a high signal - dont know which is better - and yea im not to sure about G working either - G isnt 3G though 3G=3G but yea it would seem vodafone suck and their CS is more than awful and rubbish

I very rarely see the 3G symbol too. I normally get H and G. I just walked out the office and the G went to H and I could get pages again. Does anyone know what is going on?

try next time u r at work going into "settings", "connections", "advanced", "select network" - and switch settings there from My ISP to WEB - then try connecting again.
I had the same problem for a while and this helped. However, occasionally I have to switch around when I m in an "H" signal area. Dont know why that is but I guess its not the only weird thing about this phone

Hi Amanox,
Thanks...I tried that work around, it shows the solid G and two dialled connections but when you try and access a page on IE or Opera... both say they can't locate remote server.
It's really frustrating.
Regards,
Paul.

When is shows GPRS (G), it may be that the Vodafone cell-sites (transmitter pylons) transmitter cards do not have the capacity to allow data over that frequency, whereas the 3G/3.5G (HSDPA) transmitter cards have ample bandwidth?
Just a sort of educated guess. Either that or something is screwed up in your account settings at Voda's end not allowing it.

I don't have this problem at all ...I get 3G or HSDPA most of the time in London -GPRS is the fall-back I think, when neither of the faster options is available.
What puzzled me, and I thought it might just have something to do with your issue, is that you mention manually setting up networks:-
"created a new wap and connection and setup email etc"
I do of course have tp set up Email, but have never had to set up wap or anything else ...when I've hard reset (upgrading ROMs etc -am now on R3A too) I have only ever had to enter my SIM / PIN code and that's it -I'm connected to 3G (or H or G depending on what's available)
Nothing set manually at all -other than email account (and WIFI/bluetooth connections)

My guess is that you have chosen the wrong APN. As I'm from Germany I do not know the correct setup for Internet access in the UK, but Vodafone Germany differs between WAP and WEB access as well. WAP access is really limited to a special bunch of sites, so maybe your problems are related to an incorrect setup of the APN.

Jcsxda, sorry to puzzle you. I created a Manual internet profile and a Wap connection profile as I can't edit the My Isp one the phone came configured with. I thought by creating it manually it might fix the problem. I used a Vodafone configuration guide for the SONY X1 so I must have the right APN's etc.
Foo you mentioned the APN might be wrong if that was true I would assume I would not see any connections. When I tap on connectivity info box I see a Voda INT (GPRS, 3G) and a contract WAP (GPRS, 3G) both with a timer counting up. I have set that programs that use the internet use the standard My ISP, then for programs that use a private network I have told it to use the manual connection which I setup using the UK Vodafone configuration guide.
Oh and I re-installed the firmware last night, but still have the same problem.

G, 3G and HSPDA are pretty much the same thing in terms of connecting. It's just the speeds they run at.
GPRS is around 56 kbit/s
3G (UMTS) is around 384 kbit/s
HSPDA on Vodafone UK is up to 7.2 mbit/s (although a lot of cells are at 3.6 and some are at 1.8)
Vodafone Greece have just released HSPA+ with speeds of 21.6 mbit/s.
In the UK most 3G cells have been upgraded to support HSPDA, so if your phone supports HSPDA (the X1) then you will find it rare to come across the 3G symbol.
I switch between using both the WAP and the INTERNET apns (images better on WAP, however more apps run on INTERNET), and switch between G and H through the house and never have a problem.
I would suggest making sure that the settings are 100% correct.
The INTERNET apn is the easiest as it doesn't need any proxy settings.
The apn is internet and the username and password are both web

Hi Artesea,
Please correct me if I am wrong but if I had the APN's details wrong wouldn't I be unable to surf in H areas? Which I can. It's only when just the G is displayed I can't get any access. The manual connection I created I have not added anything other than.

The crazy thing is it was all happy before I installed the firmware update..although the connection has always been weak I did get a connection at work.
Maybe I should just be happy I can still get phone calls and spend less time looking at my email...

The wap apn sometimes need (and therefore it is advisable to have) some extra proxy details.
You should have ticked "This network connects to the Internet" and "This network uses a proxy server to connect to the Internet" with "212.183.137.12" as the Proxy server.

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

I can only do talk and surf if I have wifi on.....I cant do it otherwise Do you have to do anything special to get the talk and surf to work on GSM on ATT?

Surf and talk on Att !?

When you say it doesn't work for you, does your notification bar show 3G-or-H or does it show E? It won't work if it's E.

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.

internet problem?

hi, i have not had a smart phone before and am not to sure on how the bands work but think i have a problem.
my phone is from Virgin mobile and running 1.48 stock rom, manila and radio 2.05.
few questions i'd like to ask before you read what i think my problem is.
1. is the internet supposed to run off 3g when not on wifi?
2. is 3g faster than "H"?
my problem: 3g is active, data connection is off. i open opera (or anything else) and 3g trys to connect, 3g sign disappears and "H" appears. data connection is on and using "Virgin GPRS".
i called virgin mobile tech support and they said it is meant to go through gprs.. lie?
i called htc and they said they don't think it is a problem with my phone...
i have done a hard reset.
i think it is either the 3g doesn't work, or there is something really wrong with the settings, or virgin mobile makes it like this?
please help as i may want to return it if this causes a big problem for me.

There's nothing wrong with the phone mate.
You've got GPRS (2G) and 3G which includes HSPDPA (and HSUPA). HSDPA is the fastest of those types, 3G slower, and GPRS the slowest. Your phone will try and use the best connection available, and that just depends on the coverage in your area (and how good the phone's reception is). If you're getting a strong and steady signal, I really wouldn't worry about it.
Basically, HSDPA is a faster version of 3G.

but my sisters 3g (on o2 iphone) is faster (by a lot... and then some) than mine.
ran the same video on youtube (wifi disabled) and she got done in a matter of seconds while i was buffering mid stream
with the coverage checker i ran before i got the phone it said my area was "very good" and i get 3 bars usually.
o it is connecting through gprs not HSPDPA, in the connections screen it shows "Virgin GPRS"

All I can say is that she must have a better signal with O2 than you have with Virgin.

1) Yes
2) No. H is a faster type of 3G.
My only worries with Virgin and 3G are wether they cap the actual download bandwidth available to handsets at 384kbps (despite the phone connecting with HSDPA - I had this problem with T-Mobile), wether they cap the upload speed at 44kbps and wether they block the Skype ports.
The connection name, Virgin GPRS, is just the name they gave to their data connection when they setup your phone. It could actually say anything you want if you change the settings in the phone.

It's possible that she has a better signal than you but I find that 3G coverage on O2, especially HSDPA coverage is generally significantly worse than coverage on T-Mobile (Virgin use their network).
However it could also be that the bandwidth is capped at a pretty low level on Virgin (3G rather than HSDPA despite the symbol), which I mentioned in my previous post.

o ok. ok ok. ok lol satisfied with some logical and knowledgable answers.
i believe they will have capped the data rate then (i haven't had signal problems for 7 years now on 4 different providers and the coverage map showed a very good signal for 3g here), if you can provide me with an app which would test.. o maybe speedtest.net may work i'll try them now and let you know.
