Inabuilty for Simultaneous Voice and Data

Why is the Nexus One unable to do Simultaneous Voice and Data.
I have searched hi and low.
And yes i am in a 3G area and all that jazz.

I am in 3G.
I have no problems when putting my sim in my tp2. And talking while surfing.
And i am not the only one. No one has givein a reason as to why.

Uh..unless you changed you radio settings to "WCDMA only" you should be able to talk and surf.

It should work. I do it all the time, but it is network dependent.
In case it works on your TP2 i suggest you check your settings.

Hey big guy are you using a t-mobile nexus one on AT&T? Or AT&T N1 on T-mobile? That used to send all my calls to voicemail while I was on the intarwebs

Incorrect. "WCDMA only" is still UMTS/HSPA (3G/3.5G in consumer speak), therefore you still get voice/data at once. I can only conclude that you're under the assumption that UMTS/GSM work the same way EVDO/CDMA does. On an EVDO network, all data goes through the EVDO network, while voice stays on 1xCDMA, because EVDO is an addon to 1xCDMA.
UMTS and GSM are two completely incompatible technologies that only share GSM backend features and a SIM card. The circuits in the phone are separate, the antennas on the towers are separate. You're either completely on UMTS for voice and data (inc. both at the same time) or you're completely on GSM (for voice or data but not both at once. In fact, if you're locked on to a strong UMTS signal, the parts of your phone that handle GSM shut down for power conservation and only wake up when your signal drops to check to see if you'll get a superior signal over GSM. It will do this periodically, but won't stay active for long unless your UMTS is so bad that you won't be able to hold a call. THEN your phone powers up and maintains the GSM radio, while putting the UMTS radio on standby, only powering it up momentarily to look for a better signal.
The only time you have GSM and WCDMA/UMTS powered on at the same time is during hand-offs from one network to the other. That's why staying in areas where you bounce between the two kills your battery so quickly, the radio is drawing roughly twice as much juice as it normally does, plus it's computing which one will do the better job for the moment. Even then, at that time, the phone and its OS will be using only one of the networks at a time, and if it's UMTS, you'll be able to hold a call and surf the web.

TMO on TMO.
Attached are my settings.
I have this on every rom or radio i try.

Hey, sort of same thing just happened to me
in my case using GSM Auto (prl) or WCDMA prefered I can connect to HSDPA but GSM is in emergency calls only, weird.
but I can do both on GSM only (GPRS/EDGE)

Re-flashed to official release of 2.1 same thing.

i use voice and data on my nexus at the sme time every day. it just works. as long as you have a 3G symbol next to your reception bars, then it works.
i dont know what you could have done to break this. can you demonstrate to us what you are doing that is not "working"?

I am connected to 3G network. Call comes in. I can not browse on the internet. While i am on the call i go check settings and i have droped to GPRS. As soon as i hang up i go back to 3G (HSDPA)

Have you ever changed your build.prop file at all in the past? If so that's the problem. Change to hsxpa=2 to fix it.
If not then I have no clue.

I have no problem on my TP2.

I use it often too but today I was unable to it. Hopefully its because my area is being updated to hsdpa+

i think i have the same problem. 3G drops during voice call, doesn't connect during the call. reconnects after the call ends.

When you have bad reception, that's what happens. Normal and expected. During the call it won't re-negotiate 3G, only when the call ends.

Yeah, that is normal and it really sucks when you're on a long call. Once you lose 3G signal it's gone for good. I don't know if it's a network problem, or the phone, but it should be fixed.

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.

Radio switch

Has anyone out thought of a switch for root users on 4g phones to disable 3g so you don't have 2 wireless radios for 3g and 4g running at the same time? If so, can someone name the app, or tell me where I can find the info on it?

I think if you disable the 3g radio you would have no voice or text. Someone correct me if I'm wrong.

you're right. 4g is only for data.

I'm not sure this is correct. On the Thunderbolt, you can switch it to LTE only, and it remains able to make calls and send/receive texts. Although perhaps that doesn't disable the 3G radio.

Only reason this even came to my attention is because I had heard rumors about the Sprint users being able to disable their 3g radio and still receive texts and voicemails... So, I figured I would ask about it. I mean with dumbphones that weren't 3g how did those receive those functions without a 3g radio?

voice/text messages are on 1x while internet is on 3g/4g

Issue I see, is sometimes I'll lose 4g around here (GR area too), and if 3g was off, I wouldn't have data at all.

Than why when I'm on 3g, in a non 4g zone, when I go to make a call, the phone disables 3g?

Radio Switch
@sheatyj - I would have use for this though because I travel the country for work... Most places I go are all 4g (or at least Verizon claims them to be) so if I can disable my 3g radio, I can make my phone last a little longer... Also It will help with me having issues with my phone jumping back into 3g when I just had 3 bars of 4g.

heard of a toggle on thunderbolt a widget

How about switch to turn off all but wifi?
A nice feature of my Blackberry was the ability to turn OFF the telephone and leave the WIFI turned ON. This was great for non-coverage areas and when I traveled internationally. Can this be done on the Bionic? tnx

Just enable Airplane Mode. That will turn everything off.
Once everything is off, just re-enable WiFi and/or Bluetooth if you want to use just that.

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!

[Q] Sprint simultaneous data/voice?

On my m7 I was able to talk on the phone and continue to use my internet connection. I don't seem to have that functionality on this device. Every time a receive a phone call it drops LTE. I thought running on two simultaneous networks (CDMA + LTE) I could do both. Anyone experiencing the opposite? Did I mess something up? Or is that just how this particular device is? Any input would be deeply appreciated. Thanks.

well, lte is data only, calls cant go through lte. you need VoLTE to have voice over the lte network. and sprint doesnt offer volte, not yet at least. well, that or you need two radios in your device. the n6 only has one radio.

^This exactly. However, you can use WiFi, if available, and have the same functionality.

I completely understand what voice over LTE is and the fact that my phone uses CDMA for voice. My question was if my HTC one could use my LTE data and voice at the same time on the same network (even the same tower) why the heck can my n6 not do it? I'm actually disappointed with the lack of this functionality. I thought it was standard when sprint switched to LTE because it is essentially using two networks simultaneously.

It sounds like you didn't read the memo when it came to spark enabled devices,let me explain. Since sprint is using spark (or for tech people, 800mhz, 1900mhz and 2.5ghz) the newer phones that are spark enable (our nexus 6 being one of them) in order to take advantage of the HD voice upgrade and higher speed data, everything basically goes through one channel instead of two (basically all the older lte enabled phones). So before you had a dedicated channel for lte and a dedicated channel for voice. Now when a voice call is initiated, it's all going through the one channel for HD voice (trust me, when you hear it, you'll know it) instead of being broken up into two. Referring to what you said, it's not a lack of functionality, just the way the phones work now until, like the other posters said, volte is enabled on sprint, which hopefully will be happening this year.
