[Q] Is it possible to use data on the phone while on a voice call?

Long time AT&T customer probably switching to Sprint, been eyeing the Epic..
If I get a voice call, is it possible (if I'm using a BT headset or speakerphone) to fire up a web browser on it and use that while I'm in-call? To look things up, or whatever?
If it can't do that, are there any other Sprint phones that can (EVO, for example?)
Thanks!

if i remember right, you can use data and voice only when you are connected onto 4G and WIFI, but not 3G. i have not tested this out yet to confirm but i remember reading that somewhere if i read it right. i also came from att (iphone) and being able to use data (3G) and voice at the same time was a major plus. ill have to try it out though later on my epic.

Yes u can use data while on a call only if you are on WiFi or 4g. Tested and verified.

Well, drat. Thanks fellas. Not that I do that very often, but it does come in handy. I checked and EVO "suffers" from the same problem.
Again, thanks, that's handy to know.

Its a cdma limitation, not a device one. Both sprint and verizon have this issue.

Some might say it is a "limitation", however is it the reason why cdma networks do not suffer from dropped calls like gsm networks do.
For more information, you can check out this rather lengthy post about why cdma is better than gsm.

yeah, i experience the same thing. it's becoming pretty much a deal breaker for me, as often i am on the phone for an hour or more and am trying to look things up at the same time. no joy. plus the abysmal battery life has me glad that i am still in the 30 day window ?; i like the phone a lot otherwise. wish i could get it for ATT. i have never had problems with their service, and would love to be able to talk and surf at the same time.

On 3g only voice.
On 4g voice n data simultaneous

+1 you can thank the iPhone and this great "feature" for the ****ty network over at ATT

talk and internet at the same time?

So anybody heard about the new evo update allowing them to talk and be on the internet at the same time?

Haven't heard anything about that, have been able to do that if using 4G or WiFi.

It is a limitation with CDMA technology. You can talk and be on 4G or WIFI but not 3G.

You could probably do that with groove ip and ur Google number, u would just chew up data opposed u minutes, I have only used this over WiFi, but it should work over 3g also

I read a discussion about this once before. Basically they said that due to limitations in cdma tech, it most likely won't happen unless the phone has separate transceiver chips.
That's what they said, not what I'm saying, lol

I am moderately surprised this hasn't happened yet. Given that we have a wifi chip, an FM receiver, bluetooth, 3G, 4G...some phones have had FM transceivers as well, NFC, etc....
I am not surprised, however, because bandwidth is very limited...we're not talking back-haul, we're talking actual radio wave space....I'm dying to know what breakthrough will come along to alleviate that.
If anyone wonders why your mobile internet sucks it's oversaturation....not of the back-haul line that connects the cells to the backbone but of the very air itself as allocated. There's only so much physical space in them airs. Too may people, not enough frequencies, bands are too narrow, too many things need their own band.

It isn't a limitation. I used to do this on my Treo 755. Sprint set it up so we can't do this. There are two types of internet packages we can get for our phones and they basically ended the other one. lol.however, not many people knew that. I am getting 2M down and 768up on 3g where I'm at. when my 4g coming? hahaha
But they did it so they could limit what we do.

HAHA no you didn't. It's a limitation with cdma, you CANNOT use 3g and phone at the same time.

I think this is the same guy that came on and said the same thing on the last post that got out of hand.
This is real simple:
CDMA Technology has a limitation that doesn't allow talking and data on the same radio. End of story. No, there isn't a way around it.

Exactly why WiMaxx 4G was established, to enable that capability.
GSM is only able to achieve this because they have HSPA for the data side if i'm not mistaken.
Sprints already in the works on switching to LTE 4G, I wonder if they can just make it a hybrid WiMaxx/LTE network and have a radio capable of using either...

So when Sprint switches to LTE, will the current 4G phones work still?

There is a newer version of the CDMA spec that allows it, but Sprint hasn't deployed it. It's unclear if they will, and it's unclear whether existing phones could be upgraded to use it if they did.
For now, it's just like it always has been on all CDMA devices...no 3G data while you're on voice.

No, it is a huge limitation with cdma. Sprint isn't the only one with this limitation.

The tbolt is the only Verizon phone to offer it. It has svdo (?.) Technology. We wont be able to do it with an update.

Can anybody else's use data and voice simotaneously

I just tried it and it works. Did not work on my 4s.

Would help if you mentioned carrier. I am assuming you're referring to Verizon LTE as ATT and T-Mobile support this since they are GSM.

I know on Verizon this is only possible when on LTE. On 3G it's still impossible due to the nature of CDMA.

Yeah know that. But it's still working on 3g in Memphis Tn.

Works on my htc rezound on lte and i'm fairly certain it's the only phone save the thunderbolt that can also do it on cdma.
EDIT: Yup, works like a champ!

On SIII on vzw 3g also works when on calls

Read somewhere that this was possible due to the dual radios in the phone...
And I just tried it... and it worked, so yes, it can do voice and data simultaneously!

data and calls work on sprint simultaneously 3g and LTE (in theory LTE anyway)

Both rezound and thunderbolt can do data and voice over 3G cdma as they both have dual 3G radios.
I didn't think the GSIII could though. Am I reading right that people with sprint and this phone can?
That'd be nice if the Verizon version can. One thing I love about my rezound.

it's not actually a limitation of cdma, it's a limitation of Verizon, and i actually believe it's an artificial limitation, likely to "protect their network and users", as they like to claim for everything....
i have done it a few times on my Sprint gs3, on 3g, since I'm stuck without lte in my city right now.

This works on my sprint sg3 and it works on the evo lte... Which one of my main reasons for upgrading to a new phone. This s due to the separation of the radios that prevented this before.

As in, be on a phone call and browse the net at the same time? Yep....but I've been able to do that since my Atrix 2....dont remember if my x10 could.
via Galaxy S III

I was just doing some WiFi tethering and I received a phone call... Noticed I was still getting emails. My first thought was that my laptop automatically reconnected to my work's wireless connection. NOPE! I verified again with an outbound call... Data works on the phone and over tether DURING the phone call. Supposedly this was going to be a feature of EVDO Rev. A, but Sprint had not initiated it yet. This is freaking fantastic. I guess our phones started using 3G for voice
Sprint SGSIII blue

Sprint enabled this under their network as part of Sprint Vision. It is basically an advanced 1X data network that allows data while on phone calls. Only the newer phones with certain frequencies support it. Doesn't force us to use 4G or Wi-Fi if we want data and phone calls together. IPhones do not support this unless you're on a GSM network which Sprint isn't. Sprint is CDMA like Verizon.

I noticed this during a call yesterday and I was pleasantly surprised. When I was reading about this earlier, I thought it would be a feature supported only by towers that had eHRPD support but this is pretty awesome in itself.

It is possible with the Thunderbolt, and Rezound on Verizon. It also works with GSIII. I was a little torn about getting this phone since I figured I would lose this functionality but was pleasantly surprised when I did a test for s & g's.

[Q] Nexus 7 32GB + HSPA+

Hey,
i waited till the release of the 32GB version of the Nexus 7.On the official Google Blog i have read: "Nexus 7 with 32GB and mobile data: $299 and unlocked, on sale 11/13 in the Google Play store in the U.S., U.K., Australia, France, Germany, Spain and Canada."
Now my question is, what do they mean with "unlocked"? Fully rooted? That would be awesome!
Hope you can help me!
Greetz

I'm sure they mean, not carrier specific. its compatible with 200+ carriers worldwide.
Sent from my Galaxy Nexus using xda premium

You think so?
But what do you mean with carrier specific? Could you explain a bit more?

It is NOT carrier specific... meaning it isn't LOCKED to any specific carrier... aka it isn't branded... and it doesn't require 2yr contracts to get it for that price.
It means you pay $300 and can pop in any SIM card from any GSM carrier and go to town.

They mean unlocked as in you can use it with whatever SIM card you wanted on whatever network. As long as it is GSM of course. (LTE uses SIM even though some are CDMA based)

If it were "locked" we had to buy it from a mobile carrier as Vodafone, T-Mobile etc including a contract for 1-2 years.

Can you make calls with this or are you limited to data only? I'm also assuming this is penta band.

Data only, but there's so many ways to make voice calls online.

Thanks for every answer.Hope they will get it on amazon.de early as possible.:fingers-crossed:

Does this HSPA+ support Dual Carrier 4G?

Yeah, but easiest way, like a smartphone, would be fine ?
We now have in France, for less than 20€, full plans (3Gb fair use, unlimited MMS/SMS and unlimited phone calls). The right plan to put in a Nexus7 HSDPA !
If the Nexus7 HSDPA has capability to phonecalls like the former GalaxyTab7" or 7,7", i would replace one of my Note1 with this one !

According to everything I've found, the Nexus 7 is NOT a telephone. If you want to make voice calls you will need to use a voip service like Skype. Jellybean does have a phone app hidden away (for the Nexus 4) But I'm pretty sure if you brought it up on a Nexus 7 and tried to use it, it would either hang or make an error.
You know those portable 3g/4G routers you can buy and put a sim in? It's just like having that built in to your tablet.

My biggest question is how accessable the SIM card is....
I read in a Verge posting that it will ship with your choice of T-MO or AT&T SIM preinstalled (for USA)- does this mean we won't be able to (easily) change it?
T-MO has simple and flexible monthly 4G plan options, for cheap. I don't know what AT&T has in comparison, but the only reason I personally would go with AT&T is wider coverage.

The radio isn't 4G compatible; more of a "3.5G". It will work with 3G stuff, but not 4G apparently. Kinda strange Google didn't just jump right to 4G, if they were gonna do this at all... still, pretty awesome.

Curious to know... Source please ?

Can't wait to get me hands on one of these... we're still chugging along with a mix of 2G and 3G here in India. So this would be perfect. Our data plans are pretty cheap and contacts with cellular companies are almost unheard of...
Wonder is this will work with all the 3G carriers in India?

So, to repop the question...Can anyone confirm or deny if the Nexus7 HSPA version has the capability of being used as a phone for making regular voice calls?

So no SVDO on Sprint S4 :/

Hi, about a week ago I finally upgraded to the S4 from the S3. And so far, I absolutely love the phone! Only let down, no SVDO (which is dual CDMA radios allowing for simultaneous phone calls and data for those of you who don't know). Because that was one of the features I loved about the S3 and I utilized often. Especially during boring phone calls and/or being put on hold for while. It would allow for me to surf the web, or go on FB while being on a call.
But rumor has it that they decided to forgo SVDO because Sprint was well on their way in deploying LTE, and simultaneous LTE/Voice is possible.
I don't currently live in an LTE area. Can anyone in an LTE area confirm if this is true??
Thx.

Yes it works with LTE as the LTE and call use two different radios. Thus letting us use voice and data at the same time. Works while on WiFi too. Only 3g it doesnt.

Yes it only works on WiFi and lte for Sprint. All though other carriers that actually have good networks and even t-mobile can do it. Just one more thing Sprint's network lacks.

Nope. You need LTE or Wifi. The S3 will probably be the last phone to carry SVDO
