3g Tether problem - EVO 4G Q&A, Help & Troubleshooting

So I have a problem with one of my EVO not receiving calls while tethering on 3g. Can make a call.. but the person won't receive my call. Data seem to not get cut off.... I checked if DDTM was on it wasn't.
any help would be great

Umm, you can't make or receive calls while using 3g. They use the same radio.

You have to be using wifi or 4G. Can't make a call and have 3G on at the same time, as its the same radio.

I understand they are on the same radio. But from what I know, if you are on 3g and you receive a call. The data pause and resume when the call is done. My problem is the data doesn't pause. Same goes when I try to make a call.

if your rooted and have a custom rom i'd flash back to stock, then flash your rom again.

the evo is on stock 2.3 rom

[Q] Can't receive calls while on 2g

Hello,
I have my phone for few weeks already and today i noticed one major issue. I will try to explain everything as clear as it is possible.
While i am on 3g network, there are no problems at all. I can make a call, i can receive a call, i can receive SMS etc... Everything works as it should be.
When i switch to 2g that's when the problem comes in. In the first 15 seconds after switching to 2g, i can operate my phone as in 3g - i can send and receive calls, i can send and receive SMS'es. After 15 seconds there is no ability to receive any call. The caller alway hears the same song: "the phone you are trying to reach is either turned off or out of radio coverage...". Also no SMS'es can reach my phone. Despite of this, i can send a call any time i want...
There's one thing i've noticed. When i turn my mobile data on - everything works just fine (you should be familiar with turning off mobile data function), but this is unacceptable to my mind. It seems that when i want to receive a call, i should be on 3g (doesn't matter if mobile data is turned off or on), or on 2g but with mobile data turned on...
I did one test - changed the APN's entry to a messy one, and left the mobile data on. Still wasn't able to receive any calls. Thats leads to a statement: while on to 2g, i have to be connected to the internet to receive a call, while on 3g, i can disconnect form the internet and still be able to receive all calls.
Additional info: HTC Desire - unbranded, non-rooted, stock ROM.
Can anyone help me to solve this issue?
It seems this problem only appears at home. At work (15 miles away form home) i can be on 2G and still able to receive incoming calls... Any ideas?

lost the ability to do simultaneous voice call and internet, how to restore?

Whenever I make a phone call, I notice my 3G signal drops....when I back out of the phone app and go to internet, the page won't load up. It must have happened when I went on a Rom flashing spree and messed it up. I used to be able to look up numbers to places for the person talking to me over the phone. Has this happened to any of you and how do I fix this problem?
CDMA, more specifically, Verizon and Sprint CDMA, doesn't have the ability to use data when on a call.
SDMA [which Verizon is reportedly working on] will.
(Although I fail to see the point because these companies SHOULD be moving to entirely true 4g networks which are all voip)
I've never been able to do both at the same time. I heard that simultaneous Internet while on a call is a feature of 4g. But I'm not in 4g coverage.

Hmm, maybe I was on a 4G connection. It was awhile ago...but I know I was able to do it. Can't test it since I'm on virus' gengersense Rom at the moment
Its not possible to call and be on the net at the same time, as they use the same radio. You need to be connected via 4G or wifi to place a call and surf the internet, ect at the same time.

LTE Call Problem

Recently I noticed I been having this weird issue while my phone is on LTE. When it is on LTE, it doesn't seem to receive any calls. I understand the phone is supposed to switch over back to 3G, but it doesn't do so and the call just rings and nothing happens (testing with house phone).
However if I try to dial out with my phone while on LTE, it will switch to 3G and make the call. I hang up (and while still on 3G), I called my phone with the house phone and it went through fine.
What's up with that??

Similar issue with some wifi calling... when at my girlfriends old place, I would connect to wifi (with wifi calling enabled) and my mom would come by to pick me up or whatever but when she called to let me know she was outside, my phone wouldnt ring.... when I called her, everything was fine and the call would go through... have you toggled the wifi calling options at all when testing out if your phone will receive the calls? I know you said that it was happening over LTE but the circumstances seem eerily similar

[Q] No Call's on LTE

As the title says, I'm having issues making calls when my phone is on LTE, when it's not it works just fine and I can make calls but as soon as it goes over to LTE again I loose the ability. My data works fine and so do txt messages just no voice calls. When I try to make a phone call the phone just sits there at Dialing.
I'm running Sphinx ROM atm however this wold happen when I was on CM11 also.
Any ideas guys?
With Miroslav's rom I perform calls without trouble. But there is one glitch...After finishing a phone call, I might lose signal completely and the phone will reconnect to the network. This usually takes about 20 seconds before the phone is connected to the network and ready.

wifi calling - No voice on incoming calls

My device: T mobile s4 SGH-M919 using stock rom Android 4.4.4 with all OTA updates. Phone was moved to MetoPCS a year ago.
There is no coverage at my home so I rely on wifi calling to make and receive calls. For the last year it has worked just fine but in the last week I began having a very frustrating problem:
If I MAKE a call over the wifi, no problem I can hear them and they can hear me.
If I RECEIVE a call over wifi, I can hear them but they CANNOT hear me.
When I am not on wifi calling (ie using cell), everything works perfectly both making and receiving calls.
I researched the problem and this is what I have tried so far:
1. connecting to different wifi connections in entirely different locations - same problem
2. using bluetooth headphones or speaker instead of the mike - same problem
3. disabling Google Now Voice on every screen - same problem
4. factory reset - same problem
5. made sure I do not have any phone recorder apps installed (I do not)
6. switching the mute button on and off during a call - no change
Can someone please give me some advice or direct me to an answer. Needless to say Metropcs tech support is unable to solve the problem. For me this issue is not trival as I require wifi calling at home as I am in a rural area with no service.
Thank you
This happens to me as well. However, if i am to say "answer", and allow the voice command to answer the call it works properly but starts the call in speaker mode. Then you just turn off speaker, and conduct the call normally.
This has happened to me with most of the roms i have tried.
Haven't you tried on regular call? You listed no coverage in your area.. but, it should be some where 10-20miles away your area..

Yes, If I drive to a covered area and am not on wireless the calls work perfectly in both directions.
Do you figure out yet? I get a sch-m919 has reversal problem of yours. It make wifi call fine. When make regular phone call, they can't hear me and I get hear them. I guess, we have to try out the custom rom.
