Query: Simultaneous GPRS data transfer & Voice call

I have an MDA C3. When web & walk is transferring internet Data and a call comes in, the phone does not ring. It goes directly to the voicemail.
T-Mobile customer service tell me that this is correct as you can either transfer internet data or make a call.
Is that right? I thought that was with WAP which is analagous to dial-up. Surely GPRS is analagous to Broadband.
Anyone else want to try this:
Go to Web & walk home page. Attempt loading up the guardian page (This will take a while). Whilst this is loading, call your phone number and see if it rings or goes direct to VM.
I spend lots of time browsing so I must be losing lots of calls!
Feedback greatly appreciated.

From what I have heard only UMTS devices can support simultaneous voice/data.

Yes - but not GRPS that uses GSM band instead of UMTS.
However, some devices have troubles keeping the data link active when a call comes in.

I am having the same issue (also on T-Mobile UK).
Then IE is running or AS is downloading my mail (I use direct push) all my calls go straight to voicemail.
This is worrying as I just moved over to T-Mobile for the web n walk package to allow me to have instant e-mails. This is a pain if it means I miss calls whilst my mail is downloading.
You'd think that the chances of the 2 coinciding are slim (I don't get a lot of mail, maybe 10 per day) but the wife has already complained 3 times since Friday that she went straight to voicemail, and each time it was exactly as i got a new mail.
Is this a limit of GPRS, the Orbit or just T-Mobile?
Thanks

I was surprised too... Thats why I posted the query. I thought my phone and/or SIm were faulty. But T-Mobile tell me thats how its supposed to work.
With W&W and Email, Its really hard for someone to get through with a voice call. It was worrying for me as I tend to browse the net whenever I am waiting around. This means that when I am on the bus surfing, no one can get through to me!!
Surely if there is a limitation, then the phone should give precendence to the Voice call. After all, you can pick up your emails or surfing where you left off.
I would really be interested to see if this is a T-Mobile only problem.

No itschase is spot on.
It's not a t-Mobile problem, it's the same for any GSM based network.
Only 3g (UMTS) phones can do data and voice at the same time. No matter what network you are on.

I have just run an experiment in the office as follows:-
Me (artemis with v3 black and blue) - Voicemail when data active
person 1 (MDA compact III - v3 black and blue) - Voicemail when active
person 2 (hermes) - no Voicemail when active.
We are all on t-mobile UK, and therefore it doesn't look like a network issue, but maybe a ROM problem?

What problem? Everything is working as it supposed to. If it's so important to you. Go buy a 3g phone!

I now fully appreciate that 3g phones are the only ones to support this type of behaviour.
I was trying to be helpful and post the results of my test as at that point I didn't realise that only 3g phones worked as such. I was lead to believe this by wikipedia:-
"Class B
Can be connected to GPRS service and GSM service (voice, SMS), but using only one or the other at a given time. During GSM service (voice call or SMS), GPRS service is suspended, and then resumed automatically after the GSM service (voice call or SMS) has concluded. Most GPRS mobile devices are Class B. "
Obviously this is not the case.

I incorrectly assumed that whilst browsing, if a voice call comes in, the phone would give priority to the call.
If I had known what I know now at the time I signed my 18M contract I would have bought a 3g Phone! Its just annoying that i'm stuck with it for another 12M. T-Mobile push the fact that they have set the internet free... but what they fail to get across to everyday users is that its "AT THE EXPENSE OF THE VOICE CALLS"

Because T-Mobile forced you to buy one of their 2.5g phones rather than one of their 3g phones?

I have no problem receiving phone calls while browsing the internet on the P3300.

Neither have I to be honest, the issue only arises while you are actively downloading data. However once the website has loaded, you are free to accept calls again whilst still looking at the site in the browser.

As a test I started downloading a dummy 32MB testfile on my P3300 (from speedtest.bbned.nl) and I called my mobile with another phone.
There was no problem; I received the call while downloading the file.
Maybe it depends on the operator? I am in Holland on T-Mobile

Hi,
It's not enough to have a class A (2G) device, but also DTM (Dual Transfer Mode/Simple Class A) support has to be active in the specific network, otherwise only 3G device on 3G network will provide Class A (simultaneous voice & data).
In fact, there are quite many models from Nokia during last year that support DTM, but as already mentioned, it's not enough.
FYI,
Zohar

Is that an EDGE network ?

I got the Artemis with PV Black&Blue v3 ROM.
I can receive calls while pages are loading in IE.
I think this is a provider problem.
The phone provider has to intercept your GPRS connection and establish the GSM connection. Maybe T-Mobile just rejects calls while a GPRS connection/transfer is active.
A1 intercepts the page download and my call comes in.
When I pick up, the GPRS connection is closed completely. (not just pending)
So receiving calls while surfing is no problem for me with Austrian A1 provider.
Any other experiences?

How do I resolve "Failed to make videocall"

Maybe it's me or my network operator, but i can't get videocalls to work.
Pushing the videocall button gives me the screen with two cameraviews. It starts dialing and then i can see the phone icon go from 3g to H
But then it quickly say's : "Failed to make videocall"
Any suggestions? (been searching this forum and many others without answers)

Of course it doesn't work with your phones. Neither the 8525 or Tilt have the forward facing camera, and the AT&T network doesn't support it.

More info is needed.
Which hermes rebadge do you have?
Who is your cell phone carrier?
Does your icon go back to 3g, or does it stay at H?

Better call your mobile operator for the instructions to set the problem.

Why does it not work with Orange then? Surely one operator must allow Video Calling?
Same error..."Failed to make video call"

"Failed to make video call" means : Your operator must to allow video calling for your sim card (extra payment).

On the blow-err now 2 Orange....usual green sleaves......will let you know
)

Just to add my tuppence (two cents for our American friends):
I did a video call about 18 months ago, when I first got my Hermes. Then I tried again a few weeks ago and got "Failed to make video call" as soon as the dialer screen had finished coming up. It was way too quick for the network to have tried to connect the call, and I knew I had Video Calling on my account (from the one 18 months ago, hadn't made any changes since).
I spent three days recooking ROM's, trying out different ones and even trying a standard build (that was a culture shock, it's been so long!) but EVERY ONE had the same error message.
Finally, I tried my SIM in my wife's phone, and the same thing happened on her Sony Ericsson, so I called T-Mobile. Yup, they'd somehow lost my video calling on my account! I asked for it back, she put a tick in the "yes" box on her screen and I was able to make a video call as soon as I'd finished on the phone to her.
Moral of the story is to call your network to see if it's activated on your account. Even if you're sure it is, call them to check rather than waste 3 days as I did!!

thank you all for your input.
i've a hermes with two camera's. can't be the problem
i've tried om a dozen wm5 and wm6 rom's including shipped ones
i've asked friends with hermes phones as well, they don't succeed as well
but the simcard switching, network operator thing might be the one, i'll try that.
weird it is. an operator can make a lot of money on my phoneuse when making videocalls. why shut it down?

[Q] Phone On Wifi Only Internationally?

Hey guys,
So I know that this question was already posted up for other phones, and other countries, but I just wanna BE SURE in this particular case as well...
I left California, and am in South Korea right now, and was wondering if I would get roaming charges for using my Epic 4G? What if I turn OFF the data roaming, and or set it to Sprint only? Can I use wifi without fear insane billing later?
Sorry again to have to ask a second time like this, but I just wanna be sure -- someone else who was with Verizon said her network costs $100/day to roam, and I don't make that kinda money.

Turn off data completely and then turn on WiFi. I do it in Jamaica all the time. U could also do airplane mode and then turn WiFi on. 6 of one.
Sent from my Epic on Midnight or my Galaxy Tab rooted (feels naked without a ROM)

Yeah, just turn on airplane mode then turn on wifi.
FYI, you can set it up so you can receive and make wifi calls for free (at least to the USA) using your Sprint number. If you want instructions, let me know.

Yes please! Would using that method enable me to make calls to USA numbers, or only numbers that happen to actually BE currently located in the USA?
Thanks for the help and putting up with me!

You would be able to make (free) calls to any US/Canada number, no matter where they are. And low-cost international calls (you will need credit in your Google Voice account). People receiving your calls would see your Sprint number on the caller id, and people calling your Sprint number would be able to reach you no matter where in the world you are (so long as you have a wifi connection.
OK. Here is what you do.
1) Sign up for a Google Voice account if you don't have one already. I'm guessing you will be able to do that from Korea, if not, use a US proxy server or something.
2) Tell it that you want your Sprint number to be your Google Voice number. You don't have to do this step if you don't want to, but if you don't, people will have to call your separate Google Voice number and that is the number that will be displayed on the caller IDs of people who you are calling.
3) Go to Options>Voice settings (button is at the very top right hand corner). Under forwarded phones, you should see Google chat as an option. Check it. You should see your Sprint/GV number as an option and it should be checked by default. I don't think it matters too much whether you leave it like that since your cell antennas should be off but if you uncheck it make sure to check it when you go back to the states otherwise you will not be able to receive calls with your Sprint service.
4) Download Siprdoid. The first time you open it up, it should give you the option to create a new account with your GV account. Go ahead and do that. Then press menu on your phone, and settings, then "SIP Account" (that should be the very first thing on the menu). Make sure that the "Use WLAN" setting is checked.
5) If you also want to make calls to international numbers, add some money to the GV account via their website. The rates for South Korean numbers are $.02/min and $.05/min for landlines and mobile lines, respectively.
6) When you get back to the states, either make sure Siproid isn't running or uncheck forwarding to Google chat. Otherwise you'll end up having your phone getting two calls at the same time!
That should be all! I haven't had a chance to test this out outside of the country. But I have turned off everything except wifi and tried and it works perfectly. I am confident it will work the same in Korea because it all works over the Internet. I hope I made these instructions clear enough. If not feel free to ask me to clarify.
ETA: I would also install the GV app on your phone as the Sprint voicemail app will longer receive voicemail. At least I think it won't. I deleted it a long time ago.

That won't work... you can't enable wireless in airplane mode, at least on every 2.2 rom I've used. Samsungs fault, so unless you are running cm7 don't think you can do that.
You can however completely disable the cell radio from the info menu.
1) Open the dialer enter: *#info*1111#
2) phone info (top option) - scroll to the bottom.
3) click disable radio button
Do this after every phone reboot, the radio will re-enable itself at boot.
This will turn the cell radio off but allow you to use wifi. If you leave the radio on its going to waste tons of battery searching for a sprint signal it will never find with 100% time without signal.

Can't complete calls while using HSDPA

Sup guys, i'm facing issues using HSDPA on Gnex. I can't make a call go through if i'm using HSDPA and also I can't receive incoming calls when my phone is downloading something from Play Store (like app updates and so on). Do you know how i can get this fixed? Is it possible to do it? Maybe I could change radio and try to see what happens.
Thanks in advance...
I appreciate your help!

Yeah dude sounds flippin weird... which radio are u currently using?
- Google

It might be a limitation of your cellular provider?
Although it seems to be an odd issue...
Can you tell us what it says by following these steps:
Menu -> Settings -> About Phone ->
Baseband version
Then click on Status ->
Network
Signal strength
Mobile Network Type
Service state
Probably going to recommend that you flash a new radio firmware, but we'll see...

I'm using I9250XXLA2 radio in Brazil via Tim Mobile.
Network - 11
Signal Strength - -97dBm 7 asu
Mobile Network Type - HSDPA:9
Service State - In service
After trying to call a few times HSDPA turns off and the call go through... I don't know if there's something related to Tim or Brazilian Networks... Btw, thank you guys for your help!

Question Desperate help needed Z Fold 3 SM-F926B. Cant use any sim.

Need some help guys. I am based in Australia and swapped an iPhone for the Z Fold 3. Went through the usual connection process with my sim and esim whilst connected to wifi. All was well as it allowed calls and received calls when I was home. As soon as I stepped outside my home where it was trying to use the network, it does not work. It keeps saying not registered on network. Tried to manually select network via settings, checked all APN settings from the network and all is ok. Even tried 3 different carrier sims (Vodafone, Optus and Telstra) yet still no matter what this phone will never connect to any carrier network without wifi. From there I tried 3 different firmwares from Sam mobile just in case it had corrupt firmware. Both android 11 and 12 will not work. Need help guys please. Any suggestions?

Did you try calling the carrier or going online to their site and activate the phone? Not from Australia but I think it's worth a try.

Hi there. When I first got my unlocked phone and put in my Verizon sim, it worked right away. However, when I logged on to the Verizon site, it was showing my old phone with the new IMEI and the phone could receive calls but not call out. I called Verizon and asked them to activate which fixed the issue. Can't you call the carrier and ask if they can help you figure out why you can't call when on the cell network?

That is the same error I get here in the States if I try to manually connect to any roaming network (network other than T-mobile, the carrier I use).

It works on T-mobile, but it refuses to connect to any other network, and if I try manually to switch, it gives that same error message you get. Roaming is included in my plan for calls, text, and data, so it is supposed to work, but these phones have issues. I currently have the temporary fix on my phone for the T-mobile issue, so it has stopped flipping to "Emergency Calls Only" and back, but the fix prevents it from seeing other networks now. Whether it is Samsung or T-mobile who has to fix it, it needs to be fixed!
