[Q] Simultaneous voice and data no longer working?

I don't know when this started. I can no longer use data while a voice call is in-progress. :-\ I'm currently running CleanRom 6.5, but haven't seen this as an issue in those forums (though it's been a while since I've perused them). I'm on AT&T, by the way.
How can I go about troubleshooting this? I don't even know where to start, and googling "at&t voice and data problems" is unfortunately too vague to turn up anything which actually pertains to my problem.

Is it while you're on LTE? I remember reading a long time ago that LTE on this device (maybe others too) switches off when a voice call is made/received. So if you're set to be on LTE only, that could be the cause perhaps?

Is there an option for LTE only, or some way to do that? If so, I was not aware.
But I think your point is valid. It may be a switching problem, trying the other Network mode options might help.
Or there may just be a switching issue on the network side, that you can't do anything about (except report it to your carrier).

There sure is, if you enter the phone information menu through dialer (*#*#4636#*#*).

Ah, I figured it was via the "secret" dialer code.
Seems like a poor option to pick (LTE only), since LTE is not present in so many locations.

Yeah I highly doubt that option would be used very much, but it is a possible cause for this problem.

Thanks for the suggestions. I opened the testing window via my dialer, and the selected option is "GSM/WCDMA/LTE auto". So SEEMS like it should automatically get on something other than LTE. Weird.
Thanks again!

You can select LTE only within apn settings. Bearer type I think it's called or something. It's at the bottom. Doing so causes my network to stop working even in areas where I get LTE.

Try removing your Sim card, cleaning it with an eraser and resetting it.
99% of the time any data issues are dirty or jostled Sim cards. (Also make sure data is enabled in settings)

He has data. It just cuts out while on a call. I think we sorted it out anyway.

The switching does not always happen correctly, its a known issue on AT&T's network on this and other devices (although I haven't seen your specific problem before, with data and voice not working simultaneously).
You can also specify some network types in Settings>Mobile network>Network mode (without the dialer code) on CleanROM (its locked out on stock the AT&T ROM). Try to force WCDMA and see if that helps.

[Q] Network preferred type

Hello,
I have a Moto G with Android 4.3 and i want to change the network type preferred, but i didnt found this option, i always used the command *#*#4636#*#* and change to "WCDMA Only" in my old phone (Samsung galaxy y duos, Android 2.3.6).
My data acess always oscillates between 2g and 3g, there is other way to force connection only at 3g ?
Thank you guys

I also wanna know that

"WCDMA Only" should force it to be 3g only. That's on every phone I've had, and it works.

I tried. I downloaded but I don't know where to go in this app. I can't find the options or the menu to change to wcdma only. Can you please do a dummy tutorial for me?
Seriously I've stared this app for hours and still no clue

Oh, when you open the app, it's supposed to take you to the menu that you were taking about.
Look and I'm the general or q&a thread, there is another topic about this. Some people are saying theirs are locked from this menu unless they do something else. If I find a link, I'll send it over

Seriously!?
Have you tried to see each option of the app?
I'm gonna try to help you: open the app, there's a menu. The first option should be "Phone Information", tap that.
So you have a lot of information about the radio, your chip, phone number, your provider, cellphone network and more...
Look for the option like "Set prefered network type" (or something like that. I'm trying to imagine how it's written in English, once here I use it in portuguese).
That option is a combobox with a lot of other options to choose. Always use:
"GSM only" (forces to use 2G, saves battery, you can also use that from Android Config Menu)
"WCDMA only" (forces to use 3G, speed up connection, but drains battery)
And "WCDMA prefered" (the phone always try to connect to 3G, but when it's not possible, it gets 2G).
The default option should be "GSM auto (PRL)". Similar to WCDMA prefered, but read this the see difference:
http://forum.xda-developers.com/showpost.php?p=6591742&postcount=2
Be very careful with the other options. CDMA is very different from WCDMA.
CDMA is a different 2G modulation and it's not compatible with GSM neither Moto G.
EvDO is used only in some countries and providers, google to learn about it.
And LTE is 4G connection. I don't know if Moto G radio support that.
Remember: try it in you own risk! I'm not responsable for any connection problems you get. And try not to change nor tap any other option in that menu.
I'm using this app here with any trouble.

Ok, I see this menu, I select my network preferred type but nothing happens...
Am I supposed to do something after select the network type I want?
I mean, the Phone is still changing to 2g...
I'm so frustrated with not being able to force wcdma =/

Problem solved.
Download and install Phone testing from play store.
Thank you guys =]

I am on the same boat. The change I made in (*#*#4636#*#*) - WCDMA prefered - won't save. After each reboot/restart it goes back to GSM PRL.
My G isn't rooted or modified in any way, out of box state with few 3rd party apps.
Maybe is related to APN?

Network mode
HI Friends,
I like to use network preferred mode AUTO (3g/2g),
but from mobile network -> network mode there are only
two option that we can select either "2G" or "3G".
Some days back at first time when I opend this menu
neither of "2G" or "3G" was selected so It was working fine
with by defualt in auto mode.
But once I have selected this option now It is not possible to unselect both
2G as well as 3G and put phone back to auto network select mode.
Can anybody has work around for this.
I tried "Network" app as suggested but not useful for me.

In Settings > Apps you can reset app preferences which deselects 2g and 3g, but not sure it makes any difference. You lose any preferences you set for apps...

Hidden menus and dialer codes, please post them here

I presume *#*#4686#*#* still works, but I would like to know if there are others.
For Samsung devices, you can see the voice codec used during a call by using *#0011, but I found no such capability with the Nexus line.
Specifically, I would like to know the Pixel is using AMR:WB (AT&T HD Voice) or EVS:WB (T-Mobile Enhanced Voice Service).
Thanks.

...there is a hidden developer menu which you can access buy hitting the build number endlessly...

Thanks, though that dev menu thing has been around since almost the beginning of time [Android] and it does not provide for what is in scope. For most of us who root, the dev menu is one of the first things we do.

No worries. But as you posted a thread asking for hidden menus, it seemed only polite to supply an answer...
Hadn't bothered looking at your forum hierarchy status until just now...

*#*#3282#*#* gets you data services, you can turn on/off LTE bands and other junk. you need MSL code to do anything if you're on a CDMA network.
also i tried your *#*#4686#*#* and it didn't do anything, did you mean *#*#4636#*#*?

*#*#3282#*#* does not work for me but *#*#4636#*#* does. Is it because I have the Verizon variant?

Yeah, 3282 is most definitely a sprint thing

I can confirm that *#*#4636#*#* still works on Pixel 2 XL.

Open the phone app, click the "..." and go to Settings.
Right down the bottom, under "Enhanced call service", you should see Voice over LTE listed.

I don't have enhanced call settings.
Any other suggestions?

Wi-Fi calling option No Longer seen on Pixel 2

Hello Guys,
There used to be a 'Wi-Fi calling' feature present in SETTINGS >> NETWORK & INTERNET >> MOBILE INTERNET.
I've extensively used this feature during my international travels. However, I've discovered that the said feature is no longer available in the phone.
Anyone else facing the same issue?
PS: There's a new option 'Enhanced 4G LTE mode' available in the same location however. That option isn't a Wi-Fi calling feature as many have told me.
