voice and data

anyone know if voice data can work simultaneously ?

Only on atnt. Ugh.
I invented cyberspace. You're trespassing.

I thought with the Verizon LTE devices, being that they have two radios, voice and data do work simultaneously. However, this is where the big battery drain comes in as there are two separate radios running constantly.

HTC Thunderbolt on Verizon does on both 3g and 4g. It has multiple radios.

In the US voice and data work on AT&T, T-MOBILE, and Verizon's LTE network. Voice and data is not possible on CDMA networks.

Not all Verizon LTE phones can pull this off. HTC uses multiple radios to accomplish this on 3g and 4g networks. So far from what I have read the GNex might be lacking the multiple radios. We'll have to wait and see. Fingers crossed...

Correction...
The HTC ThunderBolt supports the SVDO standard that allows for simultaneous voice and data over a CDMA network. This is achieved by having dual antennas in the device. Unless the Galaxy Nexus will use the same standard by having dual antennas, it will only support simultaneous voice and data when connected to Verizon's LTE network.

i will be happy if it can on 4g or 3g ..

If you're referring to the Verizon LTE model, then you'll be able to use voice/data at the same time if you're on LTE. There was no mention of it having svdo for 3G voice/data.

If so then it's a step backwards from the Thunderbolt. I use WiFi hotspot and watch TV on my Galaxy Tab through my Thunderbolt while talking on the phone. If the Galaxy Nexus can't do this then I'm not buying it.

Blame VZW for having a CDMA network, not the Nexus for using it lol.
But just like other LTE phones, if you're on LTE, you can talk and use data at the same time. Because it does have LTE, they probably didn't care to use SVDO 3G for simultaneous voice/data on CDMA.

technically, only in GSM(GPRS/EDGE) you can't use both data and voice at the same time. In anything above 3G, you can.

How to force LTE only on Sprint Galaxy Nexus? [Without Root]

Is there a way to do this and if not is there a way to do by rooting the phone? What is the best and simplest way to root the phone if need be. Like a stock root by just rooting it without flashing new ROMS.
I have decent 4G LTE coverage like 2 or 3 bars but my 3G coverage is like 3 to 4 bars so it keeps switching over to 3G. When I am in the right spot like upstairs rather than downstairs the 4G LTE is blazing fast. If I had a program to keep it on 4G LTE downstairs that would be great.

Dialer>*#*#4636#*#*> phone information> scroll down and choose lte only from the menu
Hope it helps

That won't stick.
And you can't force LTE only even with root.
LTE is data only, how are you going to receive calls and texts?

Dialer>*#*#4636#*#*> You have to have MSL number which I can't get on the Galaxy Nexus Sprint Version. And also I heard that it does not give you an LTE only option just the same one in the system [LTE / GSM].
Also I don't care whether I can make or receive calls. When I just want to use the phone for DATA at the moment I use Foxfi so I can just use it as a wifi hot spot. When I am done I can put it back on to 3G.
Anyone know how to get the MSL number for Sprint Galaxy Nexus?
Also you are telling me with root or no root there is no way to force the phone to stay on 4G LTE? I find that hard to believe and if it is that is sad.

It is not possible to do LTE only on this device.

Why is that? Can anyone create an APP for it or is it hardware?

Is there no way to build a ROM/kernel from AOSP that has the CDMA radio disabled? does the LTE radio require the CDMA radio to be transmitting?

Exactly, I mean if the radio can be on 4G and not 3G why can it not stay on 4G? Is it still on 3G when it shows its on 4G like on both of them on at the same time? And if that is the case can you force the weaker 4g as primary and leave 3G on in the background?

Anything at all here? Will some of the apps on the market work for the Nexus? What if I get msl code and use 4G only in that? Has anyone tested that?

It uses 3G and 4G concurrently, if not how are you going to receive calls and texts?
Like I already said, changing it to LTE only in the *#*#4636#*#* menu won't stick, regardless of whether you are rooted or not.

part 2 still stands.

Yes I do not care about voice calls. If I want to download a movie or something I do not have to have calls during that time. So has anyone found any new information or app that will perform this function to Force 4G on the Galaxy Nexus? Again I do not care about Voice Calls.

All the Mifi hotspots can be set to do LTE only. This should definitely be possible especially since support for voice through data is right around corner.

Okay I rooted my phone, and got MSL code, but now when I go through all the settings I still do not have LTE only setting just hybrid as my last option. I have been reading some forums and some people with Sprint phones have LTE only option. Is this true? Do I need a paticular ROM? Anyone figure this out or have any idea?
Best,

This works on my Galaxy Victory for Virgin Mobile.. it does mean you can't recieve calls but I use it anyway..
Download an app in play store called "Show Service Mode" - costs a little $
Open the app
Select the third box to create a shortcut
Go back to the main screen and click the new shortcut
Select LTE band preference
Then select LTE ALL
DONE!!!
To switch back to normal open the same shortcut and choose automatic

4G and 3G are not actually different for Tmobile.
Wikipedia article on Evolved HSPA
So then, the question is how to turn off DC hspa. Which is probably not accessible through the maintenance menus.
But for many real world value metrics I don't know what you would gain.

I'm wondering if the OP came from Sprint? Sprint's 4G was a separate (battery sucking) radio that you could turn on and off and needed to in order to protect the battery usage.

4g on TMo isn't like LTE, it's not a separate modem to turn off like AT&T, VZW, or sprint. It's really a hopped up version of 3G. Your choices are 3G/4G or Edge.

On T-Mobile, there is no real differentiation between 3G and 4G. Both operate on the same spectrum. The only difference is the speeds. However, that is controlled, not by your phone, but by the tower you're connected to. It's easier to look at it as the same exact technology. For the purpose of this conversation, there is no more T-Mobile 3G. It's all 4G, or HSPA+, service now. The 3G brand has been retired in favor of the 4G moniker.
To put it all simply, 3G is the same as 4G on T-Mobile. To turn off 4G, you would drop down to 2G, or EDGE/GPRS, service.

And if you still want to do it.....go to settings - more settings - mobile networks - network mode and you can select "GSM only".
Strangely enough....there are a couple areas around where i live that my phone will show a 4G connection and absolutely refuses to open anything. I've found that if i switch to the "GSM only" option in those areas that at least i can get it working... slowly, but better than nothing.
Had the same issue with my previous phone. (G2) weird phantom 4G zone. :-/

[Q] download data and talk on phone at the same time?

I am thinking purchasing this phone in the next week or so and I have a question for those that already have it. I have had people (even from sprint) tell me that you can use the data with wifi OFF and place a phone call at the same time and some people (even from sprint) tell me you can't. Basically can you download a app while in a phone call with wifi OFF? thanks for your help.

Not on 3G. I hear its possible on LTE but I don't have it yet in my area.

Also articles like this one and other posts like this one. There is a 14 day return policy with Sprint so if you're in an area that has LTE, you can test. If it doesn't work, return it within the 14 days and you're good.

Thanks again for the prompt reply, I had tried to do some searches and not found those results. Thanks for the links.

AFAIK the only sprint phones with SVDO on 3g are the Galaxy s3 and the EVO LTE.

If somebody had a gs3 in one hand and a note II in the other and explained everything about them, and the last thing they told me was that I cant post on my wall while talking on the phone with the note II. I would still buy the note II with all the features and power this phone has.

From what I gather the reason this only works on LTE or Wifi is that the data is used from those, the 3g is used for talk during the call so it can use its secodn set of of antennas for data.

There are other phones with Sprint that have dual cdma chips in them (ie LG Viper)

The 3g uses the same network as voice (ie CDMA) only one can use it at a time, either voice or data. However 4g wimax and 4g lte use a different network so therefore you can surf and talk simultaneously. Unless the phone has dual cdma chips in them to do 3g and talk simultaneously which few of sprints phones are equipped with.

Disable 1x & 3G data on VZW?

if you disable 1x/cdma, you will not have voice.

I am aware of the lack of 4G voice capability on the Nexus. Is it possible to use CDMA in a voice mode and connect to data only on 4G?

it already does this if you're in a LTE area.

It still drops to 3G when I have low LTE signal. I'm always in an LTE service area or on WiFi so I don't want CDMA data at all.
