Nisha1, I'm not sure I understand you. Are you asking about how to make video calls? OR How to use camera and How to make a 3G call?
Mike

Sounds like he wants to make a video call... not possible on Cingular's network. The camera is for pictures/personal video taking only.

Not only is it not available on Cingular's network, the camera isn't even on the 8525, so there's nothing you can do about that. You want 3G calling, get a TyTN.

Then why its says that this phone is 3G phone ? pls check the cingular site

3G is high-speed data, and has nothing to do with video calling.
Directly from cingular:
The 3G (third-generation) network is the latest in wireless technology from Cingular. It gives you high-speed access to email, the Internet, and video clips, making your phone more like a PC.
...
The Cingular 3G network uses HSDPA/UMTS technology (High Speed Downlink Packet Access/Universal Mobile Telephone System), which makes it possible to enjoy a variety of feature-rich wireless services. It also gives Cingular the advantage of offering simultaneous voice and data services.

Can you prevent switching to UTMS?

Hi,
I've found that the switch between GPRS and UTMS can be a bit of a PITA. It causes TomTom to drop it's traffic connection, and makes web browsing in a marginal 3G area practically unusable as it's chops and changes between GPRS and UTMS (3G).
I've tried to create a new "Cellular Line" connection with the *99# dialup settings, in a hope that this would connect me to GPRS without switching to UTMS if available, but I can't get it to work - it just says "No modem at above number".
Has anybody got a solution to this?
Cheers,
Steve.
If you select Settings -> Phone -> Band and choose GSM (instead of Auto), what happens? Does it stick to GSM? I think it should do.
EDIT: Jus ttried it on mine. Had full UMTS signal and forced GSM and it worked!
I'm not in a position to test that at the moment (no 3G signal), however, doesn't that prevent all 3G facilities of the phone (i.e. video calls) from working?
Having said that, I can't think why I would want a video call, and I can always switch it back should I need to.
Cheers,
Steve.
Yes it does prevent all 3G features (and therefore extends battery life). Sorry, I didn't realise that this was not what you wanted to do. From your original post I thought you didn't want it to use UMTS at all.
Ideally, it was just the web browsing/internet access that I wanted to prevent switching to UTMS, but to be honest, I'm not sure I would miss video phoning - is there anything else I'm getting on 3G that I'll not get after making that change?
Cheers,
Steve.
As far as I'm aware, making voice calls on 3G is a little bit clearer than on GSM, but consumes more battery. So if you are unable to tell the difference between the two then you could fix it to GSM and save battery life.
However, don't forget that UMTS is vaunted as being 3 times faster than GPRS for internet use, so your browsing etc will slow down if you lock it into GSM/GPRS only mode. I bet this doesn't matter much for TomTom traffic though as I am sure it only uses small amounts of data. If you're happy with GPRS then go for it.
Yes, I'm aware of the speed difference between GPRS and UTMS. My main problem is that I use my Exec to update the football scores on my football club's website, but the home ground is in a marginal UTMS area, so it keeps switching on/off, and consequently takes much longer to update the score than if it just connected via GPRS.
I'll give these new settings a go, and if there are any unwanted side effects, I'll switch back.
Cheers,
Steve.
Having being in the know about 3G for some time now I'm saying that its virtually impossible to only use GSM for internet, but stay with 3G for vid calling.
Your best bet would be some 3rd party software for this as I don't think any 3G phone lets you do this.
Yes I agree Biohead. I don't even think third party software would help as the radio has to disconnect and then reconnect. So you can't do some stuff on GSM (like GPRS) and then some on UMTS (like Video calling) without disconnecting and reconnecting. Luckily for Mr Pritchard, he is not too bothered about video calling and so, hopefully, this will solve his problem.

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;
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

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)

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.

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!

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

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...

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?

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.

[Q] Not receiving phone calls while surfing web through Edge!!!

I have TMo tab with att sim. Done everything like flash, carrier unlock, root, modemswitch succesfully. I was just checking what happens when i am watching online stream video or surf web but i when i called from home phone tab is going to voice message, no rings on tab. But with wifi i can surf, watch videos and am able to receive calls. Any solutions?

That's because you can't!
EDGE is 2G, and on 2G you don't get simultaneous voice and data.
If you are connected via 3G, you should be able to do it.

BTW, that T-Mo Tab doesn't support AT&T 3G frequencies normally, and I don't know if it has a soft radio to allow for flashing that kind of support or if it's still a "hard" radio like most phones and devices are.

It is a hardware limitation. T-mo tab=t-mo frequencies and no rom or modem flash or settings can change that. So EDGE will be the fastest cellular speed you can get. And no simultanious data/voice.
Ok I hope someone fix that edge issue. It would have been better that i had bought AT&T tab because of voice and 3G.
...so why did you buy thr t-mo version? This part lost me.

It isn't an EDGE "issue" because it simply isn't possible under EDGE!

First of all, it IS an issue. Agreed, you can't do both data and voice while on Edge. However, what happens is that if you are surfing on Edge (data) and you receive a call, your data connection drops off and allows the voice connection to take control!
pat123 but i did roto's 2g modem update. Do you know 2g and data works together?

Still not an issue, because that is under the carriers control to decide whether or not to prioritise voice or data. If you are on a network that supports NOM1, when an incoming call is received the *network* suspends your data connection to allow your call through. If however, you are on a NOM2 network, this does not happen, and no amount of ROM flashing or tweaking is going to make the slightest difference.
The point is that unless you are on a NOM1 network, there is nothing you can do about it from your phone!

Dave
The technical term is network capability. That network is older than android.
Thanks all got it
