I have new S5. NO CALLS come in if are on LTE/CDMA network browsing internet and someone is trying to call you in the same time. Sprint had me changed to CDMA and in that case calls do come through. Anyone else has this problem?

As i understand, the problem is if 4G network doesn't support voice over LTE (4G is only for data). And when you receive call, the phone that is on 4G network, it must switch to 3G. And at this switch error happens. that's why you don't get call, that's why i get SMS with notification of missed call.
Been testing between network modes "LTE/WCDMA/GSM" and "WCDMA/GSM".
When i am on "WCDMA/GSM", i have no problem..

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.
Hello,
the HTC support tells me, that you can´t surf (with and without tethering) and make a phone call at the same time.
Is there a hack or patch to do this at the same time?
P.s. Somewhere i saw, that iPhone can do this with a hack.
You can do it if you're on 3G or WiFi.
If you're on GSM you can't do it.
That sounds great!
But when im on gsm in internet, does i still get incoming calls?
That is very importent for my business...
No, only on 3G. GSM supports only call or data, not both at the same time. If data is connected but not actively transferring stuff, incoming calls will go through, but if you're downloading at that moment the call will just sound busy/go to voicemail. That's a network limitation.

Actually it is not a network limitation.
There are Class A devices out there that can handle simoultaineous voice and data sessions.
GSM is not a network connection like GPRS and other. GSM is like old 56k modem which dials up a number and holds the line. Therefore, you cannot connect to GSM and make a call. This is a network limitation, not related to phone (unless you have 2 sims).
GPRS, EDGE are extensions of GSM... and today's general use of "GSM" includes those... GSM = not 3G
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.
I can call out but ppl can't call me. Do not disturb isn't on. Anyone had similar issue?
So, it's an LTE issue. I can get incoming call when I force 3G connection but when I am on LTE band 4, no incoming call.
I also don't have enhance LTE options under cellular network settings.
I sideloaded the band 12 enabler from this thread. http://forum.xda-developers.com/mot...nable-band-12-moto-pure-mm-ota-t3267057/page7
I am having the same issue.. I have to force 3G in order to receive calls! Hopefully someone can help us!
Hello,
i'm using redmi note 4 snapdragon 3/32 version for almost 1 year 6 months.
Suddenly i am facing network issue.
Though the network bar shows full network but still not receiving any call neither i can call others.
If i change network to gsm only it seems works for a while
but i want a permanent solution.
*i reset phone. Even tried different rom*
if this is a hardware issue. Is this critical?
Thank you.
Maybe it's related to your operator
Some operators switch from 4g to 3g or 2g when you receive a call or try to call someone
maybe your operator has a problem with this switch and so you are not able to call and receive
