Moble Data Not Available - disable popup?

Whenever I make a phone call, the phone (Stock, rooted) pops up a warning saying that "Mobile Data Not Available" and "Mobile data is unavailable while on this call. Apps like email, Internet and social networking will work if you connect to Wi-Fi."
I'm fully aware of the limitations on the phone hardware, and I don't need to be reminded of it every single time... and then have to click a stupid button to make it go away, particularly when I am driving. Is there a way to disable this stupid popup? I can certainly get into system files (since I'm rooted)... just need to know what to do.
Please keep in mind, this is different from the warning some users have complained about which pops up a similar warning when they disable mobile data... this is a different popup that happens with phone calls.
Thanks in advance!

so you don't have VoLTE?

Never turned it on because coverage is spotty at my house. I wish it would be VoWIFI, then I'd be all over it... I assume it doesn't work that way, correct?

It's warning you the phone is dropping down to CDMA for a phone call, which can't handle data and voice simultaneously.
VoLTE can. So, if it's giving you that warning, you are probably on stock ROM?
If you used VoLTE, it would not give you that warning.
I'm also assuming custom ROMs don't have that warning, but I'm not sure -- since I don't use Verizon and I always have simultaneous data/voice.

Correct. If you want to make VoIP calls with WiFi, your best bet is downloading the google hangouts dialer. You'll be able to make calls over wifi free to US numbers, and you can even make it so it will show up as your number on their caller ID. The only drawback is that you can't receive calls over WiFi using this app.
But to answer your question, just turn on advanced calling. Even if it doesn't work due to your lack of signal, it shouldn't hurt anything, and it will get rid of that message.

Yeah, I know what the warning is about., I just don't need to hear about it every time I make a call... so I wanted to disable the popup. I figure if the ROM cookers have seen it, they can point me to where it is and I can remove it.
My concern with adding Advanced Calling is that, as I've heard, it's not able to transfer off VoLTE into a regular calling mode. In other words, if you're on VoLTE, you have to stay on it or else you'll lose the call... is this no longer true? If so, then I'd consider turning it on... but I can't afford to drop calls during a drive (I'm now working in sales, after all!)
Related: I saw a some info about Wifi calling, which is available on some newer phones... I know VZ doesn't let us do this on our phones (for whatever reason) but I wonder if we can enable this feature on our phones via a custom ROM or some manually added modules?

Unlikely since we haven't even figured out how to get VoLTE onto custom ROMs. Plus, Wi-Fi Calling wouldn't be as easy as enabling something. Even if we could somehow enable it, Verizon would need to allow it on their side.

This is also why I can't Wi-Fi calling. AT&T has it for premium AT&T branded phones (mine is not) and for their postpaid/contract customers (I am on AT&T in-house prepaid GoPhone). So, only AT&T can give me Wi-Fi calling, not a custom ROM.

How to enable Volte

please help me for enabling volte, I have reliance jio sim (INDIA), I installed jaguar rom even though call is not going .

There are several factors that may affect Volte:
1. Your provider may have restricted Volte only to their own devices
2. The frequency they use volte on may not be supported by the phone
3. You may require IMS credentials from your carrier
4. Your device may require modem upgrade, which is not available.
Look at Volte discussion on Z2-Z3 threads. You may need to install LP stock firmware and use a special app to select Volte modem that is already in baseband, but not activated and then return to Jaguar.
All I have said in my thread is that Volte is supported on Android side...

1. its not applicable for jio jio sim not device restricted.
2. Jio Supported LTE bands Available In C6903 So it also not.
3. Its also not coz jio open for all no need any credentials just insert sim in any phone.
I think 4th is possiblility of jio not working. hardware wise Xperia Z1 supports VOLTE so i thik its needed modem patch also. any idea? Its possible coz we are using international Phone?

Hey , does the Jio4GVoice app work for you cuz for me the call cuts out just as soon as I make it. Also what kinda speeds do you get?? I get around 150-250kBps...barely-- LTE ought to be faster.

You can only have high definition calls when both devices have a working Volte. If the other phone doesn't have it (which about 95% don't), you are limited by the quality coming from the other phone. In other words, the channel you are on is wide enough for HD, but if no HD is coming from another phone, there is no Volte quality. It is going to take years and new devices for this to work...

Bro, you don't seem to understand the situation with Reliance Jio; its a brand new 4G ONLY carrier with NO 3G/2G fallback. Which means that if your phone doesn't have VoLTE then you can't make a phone call. To circumvent this problem , Jio made an app - Jio4GVoice , which lets you make calls and send messages even if you don't have VoLTE . But that app isn't working for me. I just wanted to know if this is a common problem with the Z1.
P.S: can someone confirm that band 40 works if I unlock it using olokos' method?

Try to see if the app can be configured. If you can place a call and then it cuts off once the other party picks up, you may not have enabled the correct codec.
In my view, having a Volte only network is stupid. The company probably is cutting corners to save money. Also, check LTE speed, I bet you are not going to have high speed at all. I have read Reliance's website: looks like too much hype...
Edit: Again, the only benefit of having Volte is high definition audio and video. And neither would work unless both phones are Volte and on the same network. If you don't have that, you have no benefit of Volte. Here is the same from the Indian Express::
"HD Calling is being touted as a major feature of the VoLTE saga, but there is a caveat. Calls are in HD only if the parties engaged in a phone call are both on Reliance’s Jio network The call has to originate and terminate on a VoLTE enabled handset. You can still make and receive calls from other networks, but they won’t be in the higher quality standard that you can expect from a VoLTE call."

No , the app doesn't have much config options .
Sometimes , the phone I call rings half a second and then cuts out other times it just cuts out out without anything.
I've tried it and volte doesn't work on jaguar ROM. Any ideas??
Your right though the avg DL speed is around 200kBps where I live which ain't nothing to write home about for an LTE network . Then again our Z1 doesn't support band 40 out of the box and that's supposed to be jio's high speed band. But jio is totally free till Dec 31st and well voice calls are free forever. So being able to make a phone call with this sim is kinda important

Volte is a sip call, which requires 1 mb to connect and 3-4 mb for a reasonable quality. 200 kbps, which is gprs, is simply not enough to carry voice.

Hmm ... Maybe that's the reason . But my friends have no problem with that app. That's why I need to know if this is a Z1 specific problem.
Oh and I'd like to point out that its actually 200kBps.

AT&T HD voice on this device

i was going through my old lg g3 and saw the volte packages cant anyone port the packages to the oneplus 3t

VoLTE is enabled by default on the OP3/T. It's up to the carrier to provision VoLTE onto your device for it to actually work though. The problem with some major carriers is that they screen the IMEI of the phone you're using and won't allow you to use certain features such as VoLTE unless you buy a branded phone from them. If you call customer support, they're going to come with with some BS excuse like "your phone is incompatible with our networks or VoLTE." Large networks are prone to pulling shady stuff like this to get users to buy more stuff from them. Not all networks will do this though, as it seems India's Jio networks allow all phones to use their advanced features.
All in all, porting software from another phone will not enable VoLTE on your phone. You might be enable to enable it by spoofing your phone's IMEI, though I'm pretty sure that's illegal or against some ToS.

How can I determine if VoLTE is being used during calls?

I have an SM-N960U from T-Mobile, flashed with the US Unlocked SM-N960U1 firmware that I am running on Verizon. The vendor agnostic firmware does not have all of the screens the carrier-specific screens do, so it's not straightforward to determine what is and isn't working. If I go into Airplane Mode, and turn on Wi-Fi, I cannot call, so we know Wi-Fi Calling doesn't work. However, whether or not Wi-Fi calling works, has zero to do whether or not VoLTE/HD Voice is working. Wi-Fi calling is not a cellular technology, it is VOIP and requires the wireless carrier to also become a VOIP provider, which requires a "home" address of the device for 911 purposes. There certainly is no technical relationship between the two, and it is a service independent of wireless communications. For a wireless provider, the VoWiFi part is working with the phone to switch the data stream, depending on the signal availability, without dropping the call. VoLTE also has nothing to do with whether or not the calling party has VoLTE. All one could say is if the calling party has digital voice of some kind, such as VoLTE, VOIP, or T1, that the call will be clearer because data put into the VOIP packets would be better.

I came up with an idea and found an app called "Force 4G LTE" to prove whether or not VoLTE is active. After installing "Force 4G LTE", besides showing everything about the phone, its displays bands, and signal strength, it also displays menus used by some of the carriers that showed a toggles for Mobile Mobile Radio Power, and VoLTE, Video Calling, and Wi-Fi Calling were all toggled on as provisioned. When I clicked on Advanced, the missing Mobile Networks menu shows up with a toggle for turning VoLTE Calls, which was toggled on. It did not display a Wi-Fi Calling menu. What I didn't expect is the "Force 4G LTE" app enabled me to force any protocol I choose, not just LTE. I forced LTE, and unlike with Wi-Fi calling, it worked.

However, whether or not Wi-Fi calling works, has zero to do whether or not VoLTE/HD Voice is working. Wi-Fi Calling uses VoWiFi, which is VOIP/SIP, and operates under an entirely different set of rules that was around before cell phones had the ability to participate. VOIP might not even use the same voice encoding protocols. The best you could say is, if you have Wi-Fi calling, the odds of you also having VoLTE are greater. There certainly is no technical relationship. VoLTE has nothing to do with whether or not the calling party has VoLTE. All one could say is if the calling party has digital voice of some kind, such as VoLTE, VOIP, or T1, that the call would be clearer because the VOIP used to transmit their call between their provider and yours had better data to work with.

So I had a few misunderstandings from reading your post. It's most likely me! If you are referring to just having Voice over IP/Data connection, yes it will work no matter what for you as long as you have a data connection.
If you are meaning True VoLTE, then both parties have to have the feature running and functioning. Unfortunately there's no way to know if VoLTE is truly on unless you run a line interceptor or trace from the carrier for two known calls that are currently connected and active. That would be illegal either way. I wouldn't recommend trusting the HD icon that shows when you're connected on a call because we have tested it at work and found that even when on Edge(yeah it still exists), it still said HD even though the quality was trash.
Just my 2 cents from my limited knowledge of working in telecom for a short stint. I still do but not as in depth.
The other thing about VoLTE is it's pretty much just voip but the protocols are indeed different. I use a grenade to fish, you use a net, end of the day, we still fishin. ??*??

A man after my own heart. Grandpa used to fish with grenades. I couldn't get my hands on them, so I made spear guns or water proof fuses and pipe bombs. Who cares whether or not the fish are hungry. :laugh:

apart from the logo in the status bar near the time(that you may or may not see depending on csc setting file) and the branding when u get lr make a call,has an HD logo on the caller card screen, and of course you can litteraly hear it. its cristal clear and very noticable. its like mono vs stereo.

I have no such indicators. What I did notice, and might the only clue you get with the Unlocked US firmware, is that I noticed LTE+ shows on the status bar for a while at the beginning of the call, and then goes away.

That is a packet sniffer. You have to be rooted to use one off those. I've set up people with VOIP systems and I also did the microwave links, and fought with cities over fiber links. The problem with VOIP is there is no copper "last mile" so you need to specify an address for 911. Locating a caller with VOIP has been shaky for a long time because it became common for a corporate switch to serve satellite plants using the Internet. It requires programming the switch to tie the extension to a location. You still need to do that with cell phones but now it's getting laughable because it moves, and worse, more than one device can service the same number, so it can also be in more than one place at the same time. They are going to have to add something to both VOIP and VoWiFi that uses the GPS at the SIP endpoint, which may still have some flies in the ointment, but at least likely.

carrier voip (volte) has no such requirement from the user device side. because u are still using their infrastructure which they own and maintain. Wificalling on the other hand does 100% because the wifi you are using is not carrier owned nor managed. so you need to enroll and provide 911 info like actual adress and contact info and consent that if death occurs its not on them because localization is not insured.
as of late i have deactivated wifi calling as for the reason it exists, its actually giving me poorer calling experience. i dont know if theres is something wrong with the phone's policy but using the setting to prefer the mobile line, i often find the device doing calls over wifi regardless of the good mobile signal connection. but its been a while so ill test it out again.
edit
so i just tested it and when wifi is weak wifi calling disables amd when strong it reenables.
the policy is strange it should have this behavior on weak cell signal and not on weak wifi signal...

So LTE+ indicates VoLTE and LTE+= indicates carrier aggregation. I did not know that.
EDIT: I JUST figured out our conversation. I said maybe the LTE+ that I saw during my phone conversation was an indication of VoLTE, since LTE+ is the first version with VoLTE support. Your answer states the added + indicates carrier aggregation, implying that it doesn't mean LTE+ features. For some odd reason I interpreted your response that the equal sign would be in the display. Maybe it was taking a day off and catching up on my sleep that made the difference.

VoLTE and WIFI calling in US

Hi everyone,
Have a global version of X5 Pro.
Trying to make VoLTE and VoWIFI working on T-Mobile in US but no luck.
No toggles in SIM settings and toggles in Phone Info are grayed out.
Any ideas to activate it?

Same with me, I started another thread or two concerning this issue but I believe it has to do with T-Mobile's VoLTE/Wifi-calling provisioning relative to the Find X5 Pro's firmware?
Of course the phone supports VoLTE and WiFi-Calling, so I'm not sure why at least the latter won't work (or at least have a toggle). If you google 'how to enable WiFi calling', most people tell you to set (or re-set) your E911 address because it's a necessary feature of WiFi calling. Ive done this on the T-Mobile website AND with a support rep on the phone, but still no toggle to enable.
I haven't found anything about this outside of XDA so perhaps it's time to submit a ticket directly to Oppo.
Edit: could anyone from the EU/UK chime in on whether they have the toggle options for VoLTE/WiFi-calling? I think we need to identify whether the problem is based on region/carrier rather than the phone.

Pulled from a recent T-Mobile forum post about the same issue (but on multiple different phones):
"In order to enable WiFi calling from an unlocked phone, there appear to be several components which all need to align perfectly. The the phone must have the physical capability, obviously a WiFi antenna. It also seems to rely on VoLTE provisioned and WiFi calling provisioned abilities.
The former carrier must have unlocked the device and its IMEI for use on another carrier.
The current carrier must have enabled WiFi calling, and also configured an E911 address.
"Exactly! The firmware in the Sprint S8 is not compatible with T-Mobile’s WiFi Calling implementation. XDA might offer some work around through flashing or root, but through normal methods, WiFi Calling on such an old device that actually has carrier specific firmware isn’t going to work with a different carrier for those feature implementations.
