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.

[Q] Can you connect to HSPA or Edge during a call?

I realized today that when I pick up a call my phone cuts off HSPA and Edge, and it was a pain because I wanted to look something up important when I was outside and on the phone with someone. Is this normal? My phone is completely stock with the OTA. It would connect to WiFi but not HSPA or Edge during a call. I remember that I've looked up stuff online while talking on the phone before, but I'm not too sure if I was on WiFi or HSPA/Edge.
Can someone confirm that is a standard thing? Or is there something wrong with my phone?

You have to be on 3G+ to stay connected while on calls.

If your under EDGE coverage, meaning your in a call with EDGE mode... you CANNOT access the Data (or web, internet) but with 3G which is Dual Mode... your Browser should load up pages (ie your internet should be working).

[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!

The technical term is network capability. That network is older than android.

Thanks all got it

[Q]Data and MMS help for Tmobile on unlocked i337

Hello, I have an unlocked i337 and i am currently using it with Tmobile. Almost everything seems to be working fine with it except a few hiccups and I was hoping someone could help me figure out what is wrong.
1. After I unlocked it using the service method I was getting 4G (HSPA+) speeds most of the time and sometimes 4G LTE speeds. The data speeds were great and I was receiving incoming and outgoing text messages fine. But while I was able to make calls just fine I was unable to receive any calls. Anyone who dial my number would go straight to voicemail. After messing around a bit with the phone my solution was to us *#2263# and select "WCDMA and GSM only". Once I did that I lost the LTE speeds but I was able to still maintain HSPA+ and receive phone calls.
Any solution to this without sacrificing LTE?
2. While I can can receive MMS messages fine it takes a really, really long time to send one(hours) and sometimes it doesn't send at all. My data is HSPA+ and pretty fast and I have excellent service in my area so I can't figure out what is wrong with it. I have been using Viber and tango to get around it.
Any idea what I can do?
3. I have to make frequent trips to a hospital for my son who has a congenital heart defect(so we are there for 6-7 hours at a time). In the hospital, the service is very poor but they offer free wifi. My previous phone was a tmobile Note 2 and it had wifi calling so I was able to get service while there.
Can I flash a tmobile S4 ROM to get wifi calling to work? Will I lose my unlock or brick my phone if I flash it? Should I use the MOD that enables
all AWS bands first?
thanks in advance for any help you guys can give.

No network/service only on 3G/H+

Hi guys, first af all sorry for my english, i'll make it quick.
My galaxy note 3 (custom rom, last bootloader and modem flashed, imei is right and confirmed by my carrier that is not blacklisted) find network/service and i can make calls ONLY when is on 4G/LTE. If i'm in a place where there is only 3G H+, it says not registered on network, i cannot do calls (emergency calls work) but the most amazing thing is that i have the typical no service icon, on his right there is 3G or H+ symbol and mobile internet works!!!
How that is possible? I cannot do calls but mobile internet works -.-
I tried everything i found on this forum, advice?
Thanks.
