[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

Android 2.3.4 on Sprint's Nexus S

Is that is updated Gingerbread or it is just because Nexus S 4G has a different hardware then Nexus S?
http://www.bgr.com/2011/03/23/hands-on-with-sprints-nexus-s-4g/

The baseband is newer I think as is the build number?? perhaps one of our more technical members can confirm?
Interesting.....

The build seems to be newest...
GRI40 or GRI54 in 2.3.3 and this is GRI75

Probably to add wimax support, also epst settings maybe all cdma phones have that

It would make sense that the baseband and build are different. After all, the radios for Sprint, both 3g and 4g, are completely different technologies than what we have in our plain Nexus S phones.
That also begs the question: If you're not in a Sprint 4g area, or are in an area where coverage is crappy, can you use data and voice simultaneously over the 3g? This is a common CDMA problem. I'm thinking you cant. Sucks to be those guys...

No - AFAIK there's only one phone that supports simultaneous voice and data over EVDO and that's the Thunderbolt. Normally the phones drop to 1xRTT when a call is initiated (at which point data says goodbye).

No they do not..THERE IS NO SPRINT PHONE THAT SUPPORTS SIMULTANEOUS VOICE AND DATA OVER 3G EVDO. Only over wifi or 4g wimax.
For now, only VZW's Thunderbolt does voice and data over 3G EVDO in regards to CDMA.

Yep tmobiles version gets me 6mbps download and 1.5 upload anyways. Id say try in your area before you buy 2.3.4 is not a os change really

That's correct and the Thunderbolt uses SVDO not EVDO which is what allows simultaneous data and voice.

Thanks for the additional info.

I don't know if Sprint is waiting for their Network Vision/1X Advanced to be activated on a few select markets later this year, but they have pre-production phones with the SVDO chipset.

from what i heard there are some system updates and bug fixes, most important is voice chat and video chat is now available in Google talk

Video calling over Gtalk.

Sprint switcing from Wimax

Well as many of you read on Engadget about Sprint switching from WiMax to LTE. Well naturally being curious, while I was stopping by my parents house on the way home I asked my dad who worked in telecom for most of my life doing contract work for Sprint. He now has since moved out telecom to some other department, but he still keeps up with his telecom friends who do contracting work for Sprint. Anyways back to the point I asked if these rumors were true. He said Yes they are switching from WiMax, but not to what and that Samsung is providing the equipment. If i find out anymore information I will let you know.

i dont really know anything about the 4g radio in my evo, but would it still work on LTE?

Everything would still work on the phone but the 4G LTE.

There aren't phasing out WiMax yet from what it sounds like, but since the Evo 4G wasn't designed with LTE in mind then no the LTE won't work on the Evo.

but does this mean that they are going to stop expanding the 4g network, and focus only on getting LTE up in more places? this is kind of a kick in the balls for people who just bought 4g capable devices with sprint.

They'll probably continue to expand and run Wimax on 2.5 Ghz and run LTE in parallel on 850 Mhz.

The way I understand, you would be able to swap out cards in the towers to swap out from wimax to lte... At least on new towers. Is that true?

Yes, but you can't swap out the hardware in your phone from wimax to LTE.

So sprint gonna issue new lte Evos to us? Lol I mean if this happens then I guess we all have grounds for leaving sprint without etf for them not holding up to their end of the contract....wimax. not saying I'd leave but I enjoy 4g.....on my Evo!

No lol.. i am sure if you have 4g service you would still get it.

No offense but you have like 5 posts Including 2 in this thread, and you've been a member here just as long as I have pretty much...I'll believe it when I see it, and as ruge said, the evo will be the compare to as the nextel chirp phones back in the day and the razor, obsolete, trust me, no evo will have lte

the Evo 2A will have lte, I promise

Edit: I am changing this because I read this post wrong. You are right they are about to use Samsung products on the new towers but its not to change wimax, it is to make the towers more efficient and smaller. From what I was told they will use new technology which will allow them to add all services on one tower and be able to free up frequency to build out. It would not be imho to drop wimax because they will be the only ones to utilize it giving them an advantage in developing. Back on topic he is correct they are making upgrades and using new hardware within the towers but I think its imho to have voice/data simultaneous on a cdma network (a first) and they will do it with wimax 2 starting 2012...(that is just my opinion)

Sprint also stated recently they were keeping there 800 spectrum and making upgrades to it for business who utilize the "ptt" phones and not using it for lte. All it takes is a little reading....

I believe I know the article you are referring to as it was in another thread on here and discussed the new PTT service they will use once IDEN is turned off and it will include more speeds and the likes for data.
The way I took the article was that the new PTT phones will take advantage of the new network upgrade they are performing i think its called Sprints Network vision. The multimode base-stations will be the key to it all.
In the end the change allows them to use all the networks more interchangably from what I understand.
I would not expect them to keep the 800MHz band for CDMA PTT. they stated that CDMA PTT phones will be out late this year and if thats the case and they were planning on having them run on the IDEN 800MHz band wouldn't IDEN need to be shut off first? I take it as the CDMA PTT phones will run on the regular network and use data form the 800MHz once they deploy LTE on that. they can't put WiMax on the 800MHz b/c WiMax isn't provisioned in that spectrum at this point.

As I stated in my edited reply it would not make sense to use technology the others are using because it would not make good marketing. Also wimax 2 will be out second quarter or half this year, can't recall, and around the exact same time frame for those new phones. Also the new hardware being supplied to sprint and their new plan is at the core of what wimax 2 is. Which is stated to give better download speed and efficiency thru multi data channels. The company supplying the hardware, Samsung, also The first company to test wimax 2 and said it got 130mbs download, but that's with no one else testing it. But you get the picture.... I hope

My main issue with sprint is signal penetration. Once I get in a building or etc my signal just goes to ****. My coworkers have t-mobile and Verizon and they get full bars sitting next to me laughing at my 1 bar. It has been this way for years.

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.

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.

Both rezound and thunderbolt can do data and voice over 3G cdma as they both have dual 3G radios.

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.
