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.

4G and WiFi Not Compatible?

I had been having problems getting 4G at home and just noticed that if I turn off WiFi, 4G pops right up and as soon as I re-enable WiFi (which connects to my home network) 4G disconnects. Has anyone seen this behavior? When you think about it, it makes perfect sense, and since both are enabled to connect when the other one isn't, the flip-flop is automatic. But it surprised me.

its probably because sprints 4G is based on WIFI. or it just cuts off 4G cus you dont need it anymore

I believe it works the same way as WiFi and EVDO works on older phones. When you turn on WiFi it will use that as your data connection instead of EVDO regardless if it is a crappy WiFi connection.

Yeah, it's actually pretty cool, but if you don't know about it, it gets frustrating. I called Sprint customer service and he had me go through the battery out/in routine and go outside and try, etc. So maybe they don't know about it either!
But it makes sense for Sprint, since their data plan is unlimited and they want to avoid network overloading (are you listening AT&T? LOL). The only thing you miss on WiFi are location-based sevices that rely on GPS (navigation, some weather products, etc.).

WiFi and 802.16e aren't all that similar. LOTS of differences between the protocols.
Maybe there's some isolation problems on your device as Sprint is using their 2.5 GHz spectrum holdings for their 4G network.

4g network and 3g network both will shut off when enabling wifi. Why have 2 forms of data going at the same time? Its not gunna use both to double your speeds.
You wont lose any GPS features. Turn on wifi and load up Google Maps, it will find your location exact.
When making calls and sending text it uses 1x so you will still receive everything except for MMS. Maybe they fixed it to where you can receive them even when on wifi with the Evo, not 100% sure.

4g and WiFi are both data only connections. You don't need two data connections simultaneously so it is smart enough to auto disable one to save battery. It would also cause routing problems.

Every phone does this LOL When you switch on Wifi they turn off 2g,3g,4g etc because you can't use 2 data connections at the same time.
I'm curious why you would want 4g and wifi on at the same time?

I thought this was pretty common knowledge (on any Android phone)... And I also thought it was done for battery conservation reasons as much as anything else. WiFi's a simpler point to point connection and from what I understand it sucks less power than 3G or 4G which is constantly checking for additional cell towers in case you've moved, etc.
If you're at home or at work w/a stable WiFi connection you should be able to preserve more battery power by using it, within the settings you can even set it so the phone doesn't revert to 3G when it goes to sleep (the default setting IIRC), otherwise it does this and only jumps back to WiFi when you wake it ('till you're out of range anyway).

I agree with all the comments. And if the Sprint Customer Service guys had said, "Hey, you idiot...it's supposed to do that," then I wouldn't have posted. But the fact that he was as stumped as I was prompted me to post (we all know that Sprint gets all it's info from reading these forums...LOL).

Google Talk on Epic 4G questions

Okay, just to step back a little, I installed Google Talk to my Gmail on my desktop pc (free phone calls to anywhere any phone in the USA). It works over internet (VOIP) via wifi at home.
I have Google Talk on my Epic 4G.
1. Does it work the same way as on the desktop?
2. Does it work over wifi for true VOIP?
3. If so, are the calls free or do they come off my minutes plan?
I had set my Epic to "wifi" mode and made a test call to my other phone. It went thru but- did it really go thru wifi or did my Epic sense it was a phone call and routed it via 3G?
If indeed Google talk does VOIP phone calls from the Epic, then there would be no need for me to get one of those "Airaves" as I only have 0-1 bars inside my house but 3 bars minimum outside (3G and 4G)

[Q] Why use 3G when you can use 4G?

I work at my local grocery store. Inside the store, there's little to no signal with 2g/3g...but when I turn on 4g, I have nearly full signal. I tried sending some texts while 4G was active, but they said it could not be sent due to not having 2g/3g signal. Same goes for phone calls. Does 4G really only apply to my browser/speed test? Pretty lame if you ask me. I should be able to send texts through 4G.
Is it just a setting on my phone?

You can't send SMS or Phone calls over 4g. The SMS and Voice rely on 1xrtt protocols which 4G doesn't support ATM. Give it time - its new tech still. At least you have 4g near you - i have to drive like 100 miles.

4g is data only. 3g is data only. 2g is voice and text. I'm not sure, but you may be able to send texts via google voice over your data connection.

I see. It's not a huge problem because I can still use Pandora while working. Muhahhaaha
Thanks

One more question, sometimes tether doesn't pick up my 4G signal, is that a setting issue?

1xrtt calls coming in while surfing

is there any way to make it so if im on 1xrtt and surfing a call can come in?

Calls override data.
Sometime this year, Sprint is supposed to upgrade to 1x Advanced. So once that's done and one uses a phone capable of 1x Advance, you'll be able to surf and be on a call at the same time. Sorry to say, the Epic is not a 1x Advance phone.

Right now the only way to do that is use wifi for data or 4g for data..
if they upgrade to SVDO in the future you can do both as mentioned above...

no i meant when i am on 1x and actively surfing no calls coming ie i miss calls. is there a way to prioritize calls overriding an activate data stream?

No. There is no way to change this. That's the nature of the current 1xRTT implementation. I think this is done at the tower, and not on the phone.

I miss calls a lot when I have bluetooth on and listen to pandora/slacker.. I think the phone gets confused, too many radios active.

How do you all.even know you are in the 1xrtt network and.not 3g?

I've gotten many calls while surfing the web, even text messages come in. They did recently just upgrade my service at my house, though. (If it is a tower possibility.)
