Voice & Data

People are making a big deal about Verizon Iphone not having voice and data at the same time. I thought this was a common issue since I never get voice and data on my nexus one (Tmo) how about you guys? The only phone that gave me voice and data was the G1.

No problems here, but I'm on AT&T. I'm almost always browsing the web or doing something else when I'm talking to the wife...just don't tell her that.

LOL what guys doesn't do that. I think it must be T-Mobile they been really unreliable lately in Los Angeles.

I can confirm that I can use data while on a call with US tmobile and yes it does matter (sometimes).

i believe it has something to do with the frequencies in use.
att can do data and voice simultaneously
the girlfriends nokia on tmo can not

It has nothing to do with the frequency, and every 3G GSM network has the capability to do voice and data at the same time. I assume in your case it's just bad coverage or she's not on 3G.

if you are connected to 3g you can use voice and data at the same time. its been this way for years. if you are on EDGE then you cannot. att and tmobile both are the same in this regard.
3g HSDPA has always been better because of this over verizon and sprint.

Can you talk and surf at the same time with the bionic ???

I have been looking all over about this. I have the Thunderbolt but not happy with the HTC poor quality phone, and random reboots once in a blue.
So I am thinking in getting the Bionic.
Thanks.

You totally can talk and surf at the same time, I did it today and was surprised to see it worked very well.

Really? That's interesting... my Thunderbolt does voice & data on LTE or EVDO. From what I was told by my Verizon Business Data Specialist, it's actually not a limitation of the Verizon Network, it has to do with the antenna in the phone (which is strange, you would think they would have enabled it long ago on 3G).

I believe the thunderbolt has a separate "2g" radio and antenna that it can make voice calls on while using the 3g or 4g for data.
I'm not sure if the bionic is the same.

This is true. The Thunderbolt doesn't actually do simultaneous 3G voice/data, it has voice over 1X on a different antenna, then data over 3G.
It is *most definitely* a limitation of the network, running EVDO Rev. A which doesn't support it. Rev. B does, but VZ decided to skip it and go straight to LTE.

Cool. Thanks everyone. This definitely makes me want to get it.

I think what you are asking "What data services work while you are talking on your Thunderbolt?" If so, everything that I have noticed... Email, Browser surfing, and SMS messaging. Not sure about Hotspot Tethering, but would have to assume it does.
To qualify my previous statement regarding simultaneous Voice and Data, I didn't mean to say that both Voice & Data were 3G and worked at the same time... What I meant to say was that while my Thunderbolt showed a 3G EvDo connection, I could talk and surf. If the voice is going over a 1X network, I wouldn't know because the voice quality was just as good as always. It is safe to say that voice doesn't require 3G EvDo connectivity to function well.
Furthermore, if they made separate antennas in the Tbolt that made this possible, then both Berzerker7 and I were correct... though there is a limitation on VZW 3G EvDo's network, if the phone manufacturer's had just made separate antennas, then there are a lot of phones that could have done Simultaneous Voice & Data.

talk and surf
I just tested this myself and I am able to talk and surf at the same time with no problems but I was on 4g don't know what will happen when I am on 3g. Something else that I noticed what I think it is, is that voice is going over cdma and data is going over gsm. If you go to your dialpad and type this in *#*#4636#*#* and then go to phone information, you will see at the bottom it says gsm/cdma network auto. Here is where I found the code along with some other interesting info askvg.com/google-android-hidden-secret-codes Does anyone else have any info on this. Biggest question why isn't VZW advertising that you can talk and surf at the same time now...

If you get a call on 3G, the icon will disappear until your call is over. 4G only, not sure about wifi.

All android phones I have used allow simultaneous voice/data with a Wi-Fi connection.

The reason the Thunderbolt is the only LTE VZW phone that can do it, Qualcomm and HTC jumped through hoops to with the FCC to get them to allow the Thunderbolt. It has a total of 4 antennas and they do not exceed the legal limit imposed by the FCC. (This is probably an attribute, although not certain, of why the battery life sucks.) Therefore you can talk and surf on 3G and 4G. This antenna combo is not on any of the other LTE phones offered by VZW (They all are not HTCs the other ones), but i'm sure the next HTC 4G phone that comes out will be able to do it on 3G and 4G if it has the multiple antenna setup from Qualcomm.
One of the sources I've read, I can't find the one that I really liked though:

spark+HD Voice = Talk and Data same time?

Just asking!!! http://faster.sprint.com/2014/03/17...ts/?INTMKT=MA:MS:103013:SparkHub:Home_Content

i dont get any data when on voice calls and I'm in an area that already has spark for bands 2500 and 1900. idk if 850 makes the difference but i doubt it
Sent from my SM-T217S using xda app-developers app

Tri-Band Spark phones do not currently have the ability to use data while on a call because there is only one radio which handles everything. So, if you are on CDMA/3G, you cannot be on LTE. It won't be until Sprint offers VoLTE or similar will you be able to do this again.
The way Sprint now handles routing is by using a technology called CSFB/eCSFB (Circuit-Switched Fall-Back). When you receive a call, your phone is told to switch back to CDMA to accept the call. In an upgraded area that is correctly configured and operating, this should be nearly instant bar any technical issues. This is all handled on the network side and there's nothing a consumer can do to circumvent it outside of forcing the phone to operate in LTE mode at all times. Though, this will not allow you to receive phone calls.
HD Voice on the other hand, relies on the devices on both ends of the call as well as the network. Both phones must be HD Voice compatible for this to operate. This supposedly offers better noise cancellation and clarity.

Will nexus 6 support data while on a call?

Apparently the droid turbo can't, which is amazing as far as I'm concerned, and unfortunately a deal breaker for me.

This will be fixed soon on all the new Verizon phones. Same with the Sony Z3v.

It depends on the network. ATT can data and call.

Verizon phones can. I have a note 4 and can make calls while browsing the web

I'm not sure about all Verizon phones I guess. I just mean it's possible on their network right now

At first most likely not. Droid life did a video making a call while on Verizon and it dropped data as soon as it started calling and came back once finished.

Its not something that is broke ....the oem are making these phones with only one path from modem .... either data or phone can use but not both. ..it's been that way since g2 on sprint ...you can use wifi and phone though

You can when vzw goes VoLTE since it will be using the same network type. This uses same antenna as I phone and other moto devices that do not support simultaneous voice and data

Does Sprint's Spark network support it?

I think Verizon has given the date for the update as mid December. At least for the Turbo, that's the case. Still somewhat mystifying why you would release three major "flagship" phones— Sony zv3, Droid Turbo and the Nexus 6— before your ducks are in a row with simultaneous calls and data.

VoLTE

I'm confused. I thought the fact that voice was over CDMA is the reason why we can have simultaneous data and voice. Back before Verizon got LTE there was no simultaneous voice and data. Then once LTE came along, suddenly simultaneous voice and data worked (and has worked for me since). The way this was explained to me was that voice uses CMDA and data uses LTE (which is GSM) so they can coexist.
So I guess I'm confused about two things...
1.) Since simultaneous voice and data has been working for years now, what makes these new phones (Turbo & Nexus 6, specifically) any different. Why is this suddenly a concern again? It feels like 2012 all over again.
2.) Whatever the reason is that it supposedly does not work, why will VoLTE fix things? It seems to me that once we have VoLTE we'd have voice and data both trying to use the same pipe and have issues again, just like before LTE existed and we had only CMDA.
Perhaps someone can explain

1. some newer VZW phones dont have two radios (ie, one for CDMA voice and the other for CDMA or LTE data).
2. VoLTE with one radio has enough bandwith to simultaneously handle both voice and data. However, VoLTE has a much, much bigger problem as I see it:
http://www.verizonwireless.com/support/advanced-calling-faqs/
Will my call be handed off automatically when I move from the 3G network to the 4G LTE network and vice versa with Advanced Calling 1.0?
No, calls won t switch between 3G and 4G LTE networks. If your call starts on the 3G network and you move to a 4G LTE coverage area, your call will continue as a 3G/CDMA call. However, if your call starts on the 4G LTE network and you move to a non-4G coverage area, your call will drop.
I live in Houston....presumably a place with lots of LTE coverage. In reality, I am constantly switching between LTE and 3G. with VoLTE, I'll be dropping calls like crazy.

Simultaneous Voice & Data on VZW

I've seen the news that simultaneous voice and data doesn't work on the N6 on Verizon out of the box. Curious what people think the chances are that it will work at some point without the need to root and unlock?

They have gone to using just one antenna as is the same for the Droid Turbo. VOLTE should be coming to the N6 in the near future.

Rooting/unlocking will have no impact on this. It, like all new Verizon devices, requires "Advance Calling 1.0" which Verizon hasn't pushed to any new devices at this point. Assuming Verizon supports the device then it will get the update at some point.

Assuming the phone is made available from Verizon directly I can see simultaneous voice and data being available. I should have been more clear about my question applying to phones bought from Google or Motorola directly.

Iphone 6 and 6 Plus has it. I just switched to Verizon from Tmo and got 3 devices, 2x iPhone 6+ and Droid Turbo. Now, Turbo I had to get as that line is for business, but it will be sold for a Nexus 6. Tmobile definitely had better voice quality and I was always iffy about going to a CDMA carrier as I used to work and knew a lot about CDMA for Sprint. However, fact that they pretty much have their entire network covered with LTE made me decide to try.
Point is, with Advanced Calling 1.0 you can definitely tell the voice quality difference and using LTE while being on the phone is nice, same way it was on T-Mobile... The fact that Droid Turbo doesn't have this and is one of the premier Verizon Devices saddens me...

do you happen to know if turning off the advanced calling 1.0 on the phone will disable the simultaneous voice/data?
i was reading some wiggy things (in verizon's faq, no less) about needing to turn off the adv calling if you're going to be bouncing between LTE & 3G or its going to to drop calls. but my partner makes a ton of calls during her (SF to sacramento) commute when she needs to have data to look at.
if its just the VoLTE you can turn off, that would be great; but if it's the whole package... well, that's going to be a problem.

I am very curious about how this will work in practice as well, to the point where I may not upgrade until volte has been live for a few weeks. I have grown used to just knowing voice and data works...I am worried volte isn't going to work very well.

I'm wondering what is going to work with an unlocked Nexus 6 on Verizon. 3G? XLTE? visual voice mail? my Verizon? Asurion insurance?

Hi, sorry for late reply. But yes, it will. I got an email from Verizon as well as text telling me how to enable it. And I do see a difference in voice quality when Data+Voice is enabled. It is done via Settings - Cellular and then switch it away from Data only. I drove out while on the phone last night and I managed to lose LTE signal, my call didn't disconnect. However, I did notice odd things with it still. One time my phone went to 1x while in my pocket in a good LTE coverage area. When I took it out and saw 1x I immediately got a Voice Mail notification... I never got a call though.

the only thing making me want to return my Nexus 6 is that I can't simultaneously use data and voice on Verizon.

He has an iPhone 6 or 6+ which already supports Advanced Calling 1.0. The Nexus 6 doesn't. Yet at least.
Just for some clarity, Advanced Calling 1.0 and XLTE are Verizon marketing buzzwords for VoLTE and AWS respectively.
You can't do simultaneous voice and data on this device, or some other recent devices because there is only one antenna for both CDMA and LTE, while many previous devices had one for each.
Once you get Advanced Calling 1.0 on your account and device, the CDMA chip is not used and both voice and data go over LTE. Since VoLTE is just another type of transmitted data over LTE, it can do both.
Advanced Calling 1.0 on Verizon WILL drop if you leave LTE coverage as Verizon does not have any way to hand down from LTE to CDMA gracefully. This is different from TMobile and AT&T who can hand down to their HSPA networks. If you had a call going and it didn't drop when you lost LTE, it wasn't a VoLTE call in the first place. It's possible either the call started on 3G, the option wasn't enabled on your phone, or the option wasn't enabled on your account. I'm sorry if I sound patronizing, but Verizon's VoLTE is completely incapable of keeping a call going if you drop from LTE.
Finally, XLTE is just Verizon's term for the extra 10x10 or 20x20MHz of high frequency AWS spectrum they acquired. It's not a new type of LTE, but might as well be because the real world speeds are so much better than the normal low frequency 700MHz band of their original LTE, mostly due to fewer users, more bandwidth, and cleaner RF at the high frequency.
There's no XLTE "chip" as much as looking in the LTE band support and checking for band 4. 700MHz Verizon LTE is band 13, and they will soon start deploying more LTE on band 2. It's a matter of antenna tuning and modem support mostly.

Exactly what he said. And trust me, it isn't as good as what T-Mobile uses.
Let me ask you this, do you think T-Mobile is overall a better network in Metro areas? I loved my service on T-Mobile... From fast data speeds to very clear voice, amazing! Switching to verizon was a nightmare. Even on VOLTE it isn't very clear, calls do drop and I am getting low speeds or regular 3g in places T-Mobile had LTE in Atlanta. I do know that rural coverage and indoor is better on Verizon, but my experience has been bad.

How to get Simultaneous Voice and Data to work on Nexus 6
After updating your Nexus 6 to Android 5.1, you will find a setting hidden inside a Phone Settings menu that allows you to enable VoLTE and then an “Enhanced 4G LTE Mode.” With both of these options toggled on, you can then make calls and “surf the web.” Glory!
In order to enable the setting on your phone, head into the dialer and type in *#*#4636#*#*. When you hit that last *, your phone will jump into the hidden settings menu. Choose “Phone info” and then scroll down until you see an option for “TURN ON VOLTE PROVISIONED FLAG.” Tap that and then reboot your phone (I had to reboot twice for some reason to get it to work). Once booted, head into your phone’s regular settings menu, tap on “More” under “Wireless & networks,” then “Cellular networks.” You should now see an option for “Enhanced 4G LTE Mode” and it should be toggled on.
Note: There is a chance that you may need HD Voice added to your Verizon account. To do that, you will need to sign-in to your Verizon account and add the feature, which is free.
Go ahead and place a call with WiFi off and see if you can access a web page or an app that uses data. All good? In order to keep this functionality, you will need to leave Enhanced 4G LTE Mode turned on.

Hi.... noticed this thread hasn't been active for awhile. Just wanted to confirm that I did this today with my Nexus 6, and everything worked fine. Had to have HD Voice put on my line for free, and had to reboot. But definitely have simultaneous voice/data now.

I just did this on my Nexus 6. Works great so far. Was able to make a call and browse several web pages at the same time. Awesome info thank you!
