How to Surf and Talk on EVO 4G

Hi Guys I'm starting this thread hoping somebody out there knows how to do this or please point me in the right direction. I know it is possible to talk on the EVO and Surf in 3G at the same time. I know this can be done on 4G. The reason why I said it can be done I have a friend that has a Sprint Palm Pre they told me they can do this without being on WiFi. If we can figure this out video Calling will go alot smoother and better by using Knocking Video. If we can pull this off calling the other person on EVO or even the IPhone using Knocking video your voice would be channel through the 1x while the video without voice traveling through 3G and 4G for those who has it is. Now this is how its done overseas out of the USA every phone comes with two camera we are the ones behind. Now I know its a setting in the ##DATA# that has been disable or turned off. My thoughts are that Sprint either turned it off and not allowing this to be done yet "why" to promote 4G. Now Voice and Video consumes alot of data from both Parties Knocking Video do not as of yet have audio so therefore if we can Somehow turn this on calling your party puting them on speaker or Bluetooth video will go alot smoother. AT&T has this option where they can talk and surf but they have Face time only on WiFi. thank you guys for taking time and reading this post hope we can figure this out. I have Faith in you guys.Thanks for your hard work all of you..

edit: not going to happen sorry your friend lied.

Deceptions
I was completely deceived by the Title.
Perhaps you should have edited your Title to say "Can you use Data and Voice at the same time on Sprint?".

Your friend lied.. It can't be done..

Wrong forum. This should be in q&a. But to reiterate, with CDMA this is impossible. The network is not made for this.

Connect to Wifi or 4G. Those are your only options.

Yes you can do this but you have to be on 4G. As the others said, its not a setting you can just tweak. Sprints nor Verizons network support this on 3G.

I used to do it all the time from my Touch Diamond on Sprint - routinely, actually.
I was surprised when I couldn't do it on my Evo 4G, but eh - it wasn't that big of a deal.

your friend with a pre is a liar, I've got a pre sitting on my coffee table that can attest to it if you want

I remember being able to do this on my Mogul thought....

It is not physically possible for any CDMA phone to do this, I have no idea why you would think anything but. Using WiFi or 4G you can, but otherwise you can't.
3G is plenty for video calling anyways, voice/video run about 1Mb/sec according to fring.

nope. It's just like when you get a call or text message, anything you were doing on the net is paused. I would routinely tether to my laptop and stream netflix. A call stops that in its tracks.

Those of you saying you were able to do it with your previous phone... You're not recalling it correctly. It cannot be done. You cannot surf and talk at the same time, with EV-DO, period.
It's impossible and there is absolutely no proof that this was ever possible.
Like other people said, this is a limitation of the EV-DO technology. So unless your windows mobile handset was so slow to the point that it was showing you delayed data during a phone call , it is simply impossible.

Yes but that's one way calling and 3g for sprint is 1.something so it will be choppy. Pocketnow did a test on the iPhone tethering sprint phone with the iPhone face time and it was choppy only At&t stood up to smooth video calling. See we can send text while talking and text is data yes it is data. Before we couldn't send text while talking. And on the pre some phone where able to do this some wasn't due the the update. I'm thinking it was a test sprint was doing. Early or mid last yeah cmda purchase the technology for this to happen Its all a money thing in USA think about it. See sprint charging. Us extra $10 for this phone and future phones. I believe its a setting somewhere on this phone. Because you can turn. Receive text off while on a call and send to voicemail I was thinking somebody out there would know more about the ##data# settings. Than I do please help in anyway

IT IS NOT POSSIBLE! I don't know why you can't understand this. You might have been able to use the browser while on the phone if the page was CACHED, but 100% there is no CDMA phone that can browse and talk at the same time without being on 4G or connected to Wi-Fi.
Also, SMS is NOT data - it goes over the voice network.

To those who have done it previously with Windows Mobile phones, It was because you were connected to ActiveSync sharing your computer's internet connection, not surfing and talking on 3G at the same time. It is impossible, as it is a limitation of the CDMA technology used. Different EV-DO/EV-DV Revisions could have made this possible. However, neither Verizon nor Sprint took advantage.

Agreed with this response 100%. Simultaneous data/voice is a technical limitation of cdma/EV-DO and no amount of software hacks/settings/whatever can change that.

They both can if they're on LTE or WiFi. The Viper doesn't have SV-DO so... those are the only options.

Well you can on the GN, if on LTE.
The reason the Viper can do it is because Qualcomm puts their LTE and 3G on one radio, and voice on another in some of their devices (Thunderbolt, Rezound, Viper).
The radios in the GN have voice and 3g on one radio, and LTE on another.

Actually, it has the same radios as the Thunderbolt and Rezound, so it is one of the few devices that can do it over 3G.

Thats interesting because its not listed as an SV-DO device (although apparently it is), which is usually synonymous with simultaneous voice/data on 3G.

I only bring it up cause I thought is was weird that a top end phone can't do it but a entry device can. I came from att iPhone to sprint epic then to the nexus s cause updates are quicker on the nexus s 4g. If your a smart phone user and say you don't surf and talk your a liar. Let me call you right back I'll look it up on the web.
I forgot to mention this is in Lancaster Ca no lte in the area at all both phones were on 3g and the rep was saying "that shouldn't work your probably on wifi" I told him its disabled. He's like o.

The only time I've ever "talked and surfed" at the same time is tethering my phone to my computer and taking a call.

Like I said its only useful when tethering for me. When on Sprint it was quite annoying that every text or call dropped my tethered connection.
Talking and surfing both on the phone? Not very useful.

I've used talk and surf at the same time on occasion.
I'm on the phone and my wife asks me for an address and I have to look it up on google while still on the phone with her. I guess I could have called her back, but it is convenient regardless even though that has happened maybe twice. Definitely not a deal breaker though.

I wonder if its a ginger bread and ice cream sandwich issue cause all the phones that can do it are running on gb.

The Viper is an Simultaneous Voice and Data (SVDO) phone. FCC tests did back that up. Even the EVO 4G LTE can do SVDO. And I have needed that capability since I switched from at&t to Sprint last February. I'm glad that I'm getting the opportunity to have that feature again. And Sprint did say that the Viper will be receiving it's ICS update in the near future so I don't think that there are software limitations in Android that would cause problems with SVDO.

Nothing to do with ICS or GB. It has everything everything to do with the SoC that's used. Newer Snapdragons support SVDO.
Also, just to dispel another misconception, the GN is not a "top end phone." Rather, it's meant to be the baseline.

[Q] Data while on phone?

This is something I just discovered the other day and it kinda bugged me out cause as far as I knew data while on voice wasn't possible on CDMA.. But I was inside a cafe getting lunch, and while on the phone I had to look up something on ticketmaster and was amazed that I was actually able to surf the web while on the phone. I have had blackberries, WM phones and an Evo prior to this and it was never possible (unless on wifi) I'm in NYC so there is no LTE available yet.. Has anyone who is in a non-LTE market able to do this?

I've seen this mentioned before by some others. Here's a link to one such thread.
http://forum.xda-developers.com/showthread.php?t=1764756

Thanks! When I saw this I kissed my phone, LOL.. But really this is why this phone is so damn amazing.. It makes it so much easier to quickly look something up then to have to say "lemme look this up real quick I'm gonna call you back".

Yep it's great isn't it. The newer phones on Sprint or at least Galaxy 3 and Evo LTE are svdo capable aka simultaneous voice and data. Thank God cdma networks can now do this (Sprint, Verizon) as the gsm networks (TMobile, and AT&T) have been able to do this for a long time.

Yup! And don't forget the LG Viper it was the first LTE phone to bring the feature. Kinda messed up the Galaxy Nexus is the only LTE phone that don't support it.

yeah, I found this out today and I about screamed out of joy!. I was downloading G Maps and had to call my wife, so I called her and realized the 3G icon didn't go away, like it does on the Epic 4G (my last phone). And I had to tell my wife "hold on" and went back to my notifications and realizeed GMaps was still downloading. What a great feature on a CDMA phone. One more reason to love my GSIII I wish i could find out who thought of this, so I could buy him/her a beer. Peace!

i never even paid attention... usually the only time im using data while on the phone is at home with wifi or occasionally when im on 4g which of course is not cdma... never new this feature was implemented... good to know gsm no longer has the one up on us...

Does this chipset use a different 3G technology?
I remember when the Thunderbolt came out for Verizon everyone was amazed that it could do this and the reason was Verizon/Thunderbolt's Chipset was using some different type of EVDO revision that allowed it to work or something. Maybe I'm wrong on the technical details lol, but the general idea is right.....

Just found out you CAN talk and use data -> Mine has never worked...suggestions?

Since I purchased the phone in October I figured it was normal to NOT be able to talk and use your data... Wifi worked fine but I could never browse when I am on a call (4g etc), which was frustrating while trying to use maps. My phone was literally the first in the door at my store.
This was pre-root, and even now after Root and custom (Jedi Rom). Other than that my phone works flawless, not problems ever.
Now I may have to flash to stock rom, Reset my counter and unroot my device (such a hassle)
I am on the Monthly 4G plan with T-mo ($60)
Suggestions?
Any basic tests should I run?
Can Technical service tell I am rooted if I call them up?

Are you sure you're not on EDGE?
EDGE doesn't support simultaneous voice and data.

This is the first time I've ever heard of this since I've been able to talk and use data even since the G1 days. I thought the only one who couldn't do that was Verizon.

Are you sure you were on EDGE back in those days?
Do a little Google search, there's hundreds of pages saying the same thing. There's even an ATT FAQ addressing it.

+1 been doing it since the mt3g phone after the g1 if you don't know lol I think its funny seeing those lame at&t iPhone commercials talking about surfing the web and talking at the same time... Been doing it for years you guys are a little behind lol

Was able to do this back on my g2x, usually be able to use Internet for couple minutes while on a call and then I guess the network would eventually "catch me" and it would stop working..

Not to be a jerk but made me laugh lol we've had this for many many years.... I'm sure it worked with the g1 can't confirm cause I didn't own it but it worked with the original mytouch3g basically a g1 with no keyboard. Been talking on speaker and googling at the same time for years... Can even use the multi window and talk and surf if you wish to do it that way ...

I always thought the difference was in the technology the carrier used,
it was my impression that companies that relied on CDMA technologies, such as sprint, verizon, boost, etc, couldn't, but GSM companies could, i.e. at&t, t-mobile.
either way, if it never worked for me, i would just flash the stock rom available in the forums and hop on the phone to have a nice long conversation about what we would do to rectify this situation.

You're all missing the point, all the phones you're talking about are 3g phones, Even the venerable old G1 was 3g.
3g phones can talk and data at the same time as long as the data is on the 3g network. If you're in an area without any data service available besides edge, you will not be able to talk and do data simultaneously, whatever phone you have. That's true on any GSM network, unless you have some kind of phone that has multiple radios.
The reason the original non 3g iPhone could not do voice and data simultaneously was because it didn't have 3g. It was an edge only device. Nothing to do with being AT&T or anything like that. CDMA phones have some more limitations until the recent inclusion of multiple radios in the device, which I think started with the Thunderbolt.
The original iPhone was an amazing device for its time, big screen, no keyboard. I was happy to have one for years, but when the Nexus One came out Android has pulled studly ahead and never looked back.

Yes we know we are talking about 3g phones android had it right to begin with unlike apple... I did though have the first iPhone till I dropped it and half the screen decided to stop working... Lame crap! all in all we could talk and surf web for a long time and when phones were made with only edge there was not many devices that had worthy web browsing capabilities anyway. Don't think I'll ever go to CDMA I enjoy my sim cards and not relying on calling customer service to switch phones...

The G1, the first Android powered phone, wasn't released until 15 months after the first iPhone; it better have done things better with that much longer time to market, don't you think? iPhone users were happily using large screen, thin form factor phones for a very long time while Android was just a dream. Your also not up to speed on VZW's current phones it seems. While they do use CDMA for the voice, the data side of the phone is GSM (LTE), and you no longer need to call customer service to switch your phone as long as you're on an LTE device, which all their newer phones are. I routinely swap SIMs among multiple VZW phones, it works just like GSM, number and account go with the SIM, not the phone.
You're still missing the point. The original post complains of not being able to talk and data simultaneously. I asked if he was sure he wasn't on EDGE, then the thread devolved into a bunch of "iPhone and AT&T sucks because my old 3G phone has always been able to do voice and data simultaneously." Totally irrelevant, even if you think iPhone and AT&T suck, because it has nothing to do with the original problem. Great, your old G1 did talk/data same time, how does that help the OP fix his problem?
As for all the Apple/AT&T hate from others, whatever blows your skirt up, I guess. AT&T has its faults, and its wins. Their network is a hell of a lot better at pushing a signal into every large building/mall/structure I go to here in Los Angeles' suburbs; most of them I get ZERO signal with my T-Mo Note 2. Verizon beats both, you pay a premium, but if you need a signal, VZW is best at getting it to you. I have high-end active phones on all three networks, and often do side-by-side compares. In my office building in Santa Clarita I have to use my VZW GS3 as a hotspot to get data flowing to my Note 2!
Re: the iPhone original being EDGE only. As I recall, in 2006 when the iPhone was being developed, and in 2007 when it was launched, 3G was only in a few major markets; releasing a 3G phone then would only have benefited a lesser portion of the customer. Apple tends to play it safe on a newer, more power hungry technologies to save battery. It's a design choice that most of their customers are happy with.
Anyways, back to the original post, technical support can tell you're on a different ROM if they ask questions about software details from the About screen and they don't match what the non-root phone should have.

[Q] browse while talking on phone? lg g3

Is it true that you can't browse or do something else while you're talking on phone?

??? Obviously this is not true, I do all sort of things while talking on the phone... Whoever told you that is either playing you or is just dumb

That is true of the iPhone's on a Verizon network and I believe sprint but not true of the android devices.

False I always use chrome, XDA or something while talking on my Bluetooth headset. After all being on hold is boring.

Okay. I've been searching and it seems its because of the provider. And not the phone. Not working if you use Telia (here in Sweden) it seems for example, because the way they handle mobile data. They use the same net for calls and surfing. I had the same problem with my Galaxy S3, with the same provider.

As usual, there is some truth to this. If you are in Sprint, this phone uses their Sprint spark technology on lte (as do all new Sprint phones now). Unfortunately, this means that while in a call, you cannot use mobile data. Wi-Fi still works fine.
But this is not the phone, but is rather a feature of the provider...in this case Sprint.

This sounds pretty damn stupid and incompetent on Sprint's part. This used to be an issue with some carriers in the CDMA/TDMA days because yes, the voice and data channels were the same and limited per device. But this hasn't been an issue for years with most carriers. LTE is an all-IP network; it is the same process as the Internet. So has Sprint limited the number of ports a phone can open to traffic? Or are they implementing throttling that chokes your data when a call is in progress?
