That's correct; GSM phones [AT&T as an example] use a different radio for 3G and voice. CDMA [sprint, verizon] use the same radio for data and voice. You can surf and talk if you are using wifi or 4G though.
Because Sprint sucks. :-D. and CDMA sucks too. :-D There are A BUNCH OF limitations on CDMA. Wonder if anyone has a link to all the limitations of it. then also compares GSM and other american based networks. :-D

You can do the following:
Install grove Ip, set it to use 3g/4g enter ur google voice info, and make phone calls over data, then u can surf and talk same time. Now if u get a real phone call ur call will drop though, unless u set ur phone to ignore calls while using data.
It amazes me what peoplbash on somethinge
They know nothing about. gsm sucks so bad they had to come up with different technology just to get 3g speeds... Which is why they can surf and talk at same time gsm for talk. And a completely different technology for data

Cant we use 4g while talking on the phone? Its a different antenna for both.
3g uses the same antenna as phone calls and can not share the antenna at the same time.
How many times have you made a phone call and needed to surf the internet?
Lol all the time I'm not sure how wimax works with cdma but i kno u can with lte
Sent from my PC36100 using XDA App
so can the photon 4g be able to be on the phone and internet in the same time?
If you are on 4g you can browse and make a call at the same time. When I am on 4g I can actually be on the phone while I run WIFI tether to 2 laptops.
If you can actually connect to 4g, service sucks here in Metro Atlanta.

Is it necessary to be rude when someone asks a question? You may find the question silly, but some people actually do not know all these things. Reading through thousands of posts to find the answers can become very time consuming, and like looking for a needle in a haystack if one is new to the XDA world.
Perhaps try answering the question nicely, offering some advice, and then moving on in a pleasant manner. Just a thought.
how 'bout this.
it's not a problem or a bug, but rather the way sprint set up the network. you can browse and talk on 4g or wifi but not evdo. the only cdma phone that can do that is the thunderbolt and VZW aren't even advertising it as a feature. GSM phones can, just not cdma. hell the cdma iPhone 4 can't do it either.

what do you mean before you didn't have to use 4g? before you signed a contract with a cdma carrier or before you flashed fresh rom on your evo?
Sent from my PC36100 using XDA Premium App
If you could talk and surf the web at the same time on 3G then you are the only one, EVER.
It is not possible on Sprint's network to do that without being in a 4g area.
... there are some rude people on here ... let me give you the 411 on this subject to avoid further confusion ...
CDMA Networks:
Sprint
Verizon
Metro
some other ones...
GSM Networks:
ATT
T-mobile
so on and on...
CDMA = 1 Radio for both voice and data
GSM = 2 Radios, 1 for voice the other data
so that being said, there is a physical impossibility (not improbability) that you were ever able to browse the web and talk at the same time using any CDMAonly phone for both unless you did any of the folowing:
1. VOiP service where your voice is data, in which case you are only using DATA and not VOICE
2. you had a global phone in which case you used both, CDMA for voice and GSM for data or vice-versa
3. used WIFI or 4g for data and CDMA for voice
4. a device that has 2 CDMA radios
Definitely something I missed from AT&T..

Not to instigate an argument, but last I heard, GSM could do voice and data simultaneously not because it has multiple radios, but that's just how the network works as a feature of GPRS.

So while I wait for LTE service and a phone that can use it, I keep hearing about Sprint upgrading to "Enhanced 3G.
But what do they mean? Faster download speeds? Voice and data at the same time? Is it simply marketing BS?
I'm not finding an explanation of it anywhere.

I don't think is voice and data at the same time because CORRECT ME if I'm wrong someone BUT I believe that's a cdma issue BUT to answer your question......Enhanced 3G is just that, is better 3G! Improved 3G speeds....NOTHING more, NOTHING less!
I believe its the new HD voice service recently announced.

Not to worry... it is a new compression algorithm to get more data packets into the same bandwidth. It should improve the speed of 3G data networks.
It is about 50/50 improvement vs marketing.

No, that's only LTE.
Voice does not transmit over 3g, wimax or LTE HD voice is sent over 1x-Advanced. 3g. WiMax and LTE all are used for data and MMs only, voice and SMS go over the 1x channel, CDMA limits the use of 1x or 3g/wimax to one or the other at a time, once LTE is available when using it you will be able to simultaneously use voice and data, theoretically, since LTE will be using a SIM card for its activation, much the same way VZW LTE works.

Correct.
wait is sprint finally jumping ship to the much better evdo rev b.? or is it still rev a but updated slightly to make it not as slow?
Its rev.a but with better compression and abackhaul that will allow for about 5x the current bandwidth per tower giving off higher aand more consistent speeds

I've only used wimax 2 or 3x, but it would make sense since it is a separate radio and wimax doesn't handle voice. The biggest benefit to LTE is its going out everywhere 3g is now and should have same or similar building penetration. Hell I live in the country 20 miles from town and 40 from a real city and my towers are scheduled for LTE in phase 2 this year which I was surprised but the whole southwest of my state is getting covered in the same rollout something like 200 towers from Sarasota/bradenton to Naples

Being that Boost Mobile runs on the Sprint CDMA network, do any of you think that this new compression will also improve Boost Mobile data speeds or does Boost have their own network filters to regulate the speeds? Add Virgin mobile to that question too. Just curious.

Side Note at att store yesterday: I was at a ATT store checking out the Salaxy Note and a customer came in to exchange his old blackberry because ATT sent him a letter that ATT is getting rid of their 1x or 2x services. Found that interesting kind of how Sprint is going to upgrade all their iDen NextTel network to LTE.

To better answer/consolidate the above replies:
When you are on 3G data (watching a youtube video, on the web browser, etc) you will still get phone calls, however the data connection will stop to allow the phone call to take place. You will also be able to receive text messages however the data will stop for a brief second (the phone actually goes to 1x for a brief second)
When you are on 4G LTE, you can make phone calls with no problem. The data connection will remain active and you can talk at the same time.

Yes you still get calls. Unless you enable DDTM from settings. Which sends calls straight to vm if you're on active data.
There are cdma phones that do talk and surf but unfortunately our Notes is not one of them even though it came out after all the others ones that can! Damn Samsung Retards.. :banghead:

This is not entirely Samsung's fault. This is a 3g CDMA radio tech problem requiring SVDO being needed....and Samsung making a multi-carrier handset that has identical hardware.

I've read a few times and I'm a bit confused. You say it's a 3G CDMA radio tech problem requiring SVDO and Samsung making a multi-carrier handset that had identical hardware. Ok.. Wasn't the GS3 a multi-carrier handset with identical hardware? It handles it fine on Sprint's 3G.
The other thing that has me confused was when you said:

And this is the exact answer I needed to hear. That explains it thoroughly. Which brings me to my next question. Why didn't they go with the qualcomm instead of going backwards? It's like technology advances for CDMA 3G and then Samsung decides to take a step backwards.
Edit: Nevermind I got my answer. Sprint/Samsung sacrificed SVDO for WCDMA support instead. At least that's what I'm getting from researching.

Yes I picked that up when researching and people saying is the processor, but sgr4u and a few others speculated it really was put aside for WCDMA support for faster 3G due to the placing if antennas. Which to me makes perfect sense because if Samsung can get LTE to work on their chips what's SVDO to them?
