[Q] Why can't we use data during a call?

So I was downloading AA V7 from my phone. Since I was at work. I started about 6 20 pm. On a 100% battery. Around 8 20 pm with a 28 % battey I was at 96% when I got a phone call and canceled my download. Why o why. Damn u sprint. Does any one know if 4g will stay connected while your in a call?

Cdma will not allow data and calling its a network thing...a no no but 4g works I tested it before and it works no problem

I know, why doesn't Sprint advertise that fact? I've found myself surprised when I get a call while doing interweb things and everything continues as is. By the way, I think HBO GO thinks 4g=wifi.

And that's why GSM is so much better...
SIM cards > ESN
Data and voice simultaneously? Yes please.
IIRC it's frequencies penetrate buildings better as well.

I normally have wifi on at home because I am in between. Areas at my apt so I knew about the wifi but there is always a negative fml. But at home time for some v7. I have about 30 pages to catch up on heheheh.

I have googled something while on a phone call without 4G or wifi. Heavy traffic stops or crawls so much you may think it doesn't work or timeouts.

Okay everyone, let me teach you a little something. AT&T and T-Mobile both allow you to use data while on a call, why is that? It is actually because, back in the days before data, AT&T used ONLY GSM radio frequencies. These were perfect for phone calls and texting, but once data connections were required, their network couldn't handle it.
However, Sprint and Verizon were fine, because they used CDMA, a network that allows them to handle voice and data on the same frequency.
GSM providers were sad, so to fix it, they added a CDMA frequency to their arsenal. This means, they use two frequencies at the same time a GSM frequency to handle calls and text, and a CDMA frequency to handle data. So while you are on a call, the CDMA frequency is still free, hence the talk and web simultaneously.
Sprint and Verizon, however use CDMA for everything, so when you make a phone call, the network is being used. So data can't also get through. But 4G is yet another frequency so that can be used at the same time as a phone call.
Does this make sense?
Also, while GSM can penetrate buildings better, it is also much less reliable. It's large wavelengths allow it to travel through walls better, but also cause the dredded dropped calls that AT&T experience so much. I'll take CDMA over GSM everyday of the week. Besides, other then the rare occasion in which we are downloading (though we should never download something that big over 3G) we don't NEED talk and data at the same time.

Why would sprint advertise a flaw. That's why att advertises that they can talk and surf with the iphone duh

i know it doesnt work and it takes forever. but i am a flashaholic and damn it sucks when i go to work and the rom i have been waiting for gets released

There are a bunch of errors here.
CDMA can do Voice and data at the same time. Verison did not want that, and as the largest CDMA company, every one stopped developing new and better protocols and by default standardized on the Verizon way.
But not all Dev stopped. Outside North America there are several CDMA carriers that use EVDV? and other protocols that allow simultaneous Voice data connections on their frequencies. I believe Russia does on their 450MHz system. In fact these protocols are built in to any newer phone and all new tower equipment, but has not been implemented. Some have suggested when Sprint finishes their soft radio upgrade, they may offer it on a new phone.
Censura_Umbra had much good info, but it is not NECESSARY, from a tech point of view to have two different frequencies to do voice and data. It has been suggested that ATT wanted TWO separate systems for voice and data, as that is how big telcos are. I find this accurate.
One should also note that there are SIM CDMA phones. SIM is a separate tech entirely. North American Vendors do not use SIM cards to protect there handset hardware revenue streams. It is also why they lobbied so hard to try to get ESN modification illegal.
Final point. There are plenty who complain about frequency penetration.
1) While lower frequencies do penetrate things better, and thus may have more cancer risk
2) They also take more power to create. Thus reducing phone life.
3) Frequency attenuation do to penetration is predictable. With modern protocols, data rates can be unaffected. These things are not being implemented do to the FAT revenue streamed on handsets.

I'm not sure what everyone is talking about, I use 3G a lot while on calls.

I'm very well versed in gsm cdma and tdma networks....voice and data at the same time will depend on a personal preference. I enjoyed using it bc I do meetings on the go. Sprint's network will allow that.
Ppl are getting confused with 3G...bc they assume since ATT has this that all carriers should have it..4G allows this.....

"Death Grip"?

Hey guys, Not sure if this is normal or not, but in my house I get 1 bar signal with the phone bare and laying on the table. If I put my case on it (Spigen Slim Armor View) it loses that one bar. (without case I get 101-DBm, with the case it jumps to 109-DBm or so. I thought it was the case at first but than I remembered the "death grip" so I put my hands on both sides of the phone while it was laying on the table and it lost the bar from my hands covering the sides.
The case i have can be taken apart into three pieces. I stripped it down to JUST the TPU part and put that on the phone, and it still loses it just with the TPU part of the case on it. Originally I figured I'd just get a different case to use at home where I have low signal but it seems I can't even use a regular TPU case without it dropping the signal...
Anyone else in low services area's experiencing the same?
(Note: I have a T-mobile S4, but its unlocked and running on AT&T's network. Not sure if that matters but I figured since the phone itself is T-mobile I'd post here)

Do you get 4g lte or just 4G/hspa?

seeming you only get 1 bar in your house, i would assume any little thing would disrupt your 1 par, since its so weak in the first place. This is the reason why i love wifi calling so much because if i didnt have it, id be in the same boat as you

Yeah Wifi calling is cool but I don't make many phone calls anyway, the only problem is the 1 bar of signal is enough to receive text messages. If I have my case on and it loses that 1 bar, I get text messages about 45 minutes after they're sent to me. Which is really annoying since I hate leaving my phone bare in order to get my texts on time... Guess that's the price I pay from going to AT&T from Verizon network.
Their coverage map shows "Good" at my address (Which it is, OUTSIDE) but inside any building its garbage.

I see, however inside my house I don't get LTE (well it goes in and out, but the speeds are like 1mb down and 0.50 up when it does connect) So should I continue to keep it on automatic at home? (Data doesn't matter though, I run on Wifi at home, its just signal strength that I need increased so if the LTE/GSM setting is best for better reception I'll keep it on that at home anyway.

Using data and voice simultaneously?

I just noticed that my data shuts off when I make a call. That wasn't the case with my galaxy phone. Is there an option or something that can enable me to use both voice and data at the same time?

I've had this happen with my last several phones. I would love to know how to fix it. My HTC One X, One M7, and Moto X all do this, along with my G3.

does it really? i am still with sprint where i was able to do this on gs3

anyone figure this out? I had my GS3 on sprint and used data all the time while on conference calls on LTE or 3g. Now when I'm in a call, any app that requires internet gives me a no connection error. I don't know if it has to do with the new Spark network, but i spend a lot of time on calls and find it aggravating I can't send emails or access the internet simultaneously.

The Galaxy S3 on Sprint was one of the last phones to do simultaneous voice and data while on 3G, aka SVDO. From then onwards Sprint started building out their Spark LTE network (NOW Network) and hence tri-band (800/1900/2600) LTE phones, which could no longer do simultaneous voice and data even when on LTE (e.g Nexus 5, LG G2 etc onwards). Ofcourse if you're connected to a WiFi network, you can talk and be online at the same time.
So that feature is gone on Sprint until they implement the next phase, VoLTE (Voice over LTE), which means voice will be carried over the all data LTE network.
Hope this helps.

That feature went away when Spark phones debuted. I used to have a Galaxy S3 back then and even though i didn't have that many times where i needed to be online and talking at the same time, the few times i needed to it was really nice.
Spark phones only have one "path" which handles both voice and data, saves on battery life and data etc, that's the reasoning.
This article from back then should shed some more light. Very good read... http://s4gru.com/index.php?/blog/1/...-due-to-circuit-switched-fallback-technology/

[Q] Simultaneous Voice and Data without VoLTE?

Does the Verizon Note 4 allow simultaneous voice and data like the S5 and, basically, all prior android devices on Verizon? Or is it like the Droid Turbo / 2014 Moto X where it won't be doing voice/data at the same time until it receives the VoLTE update?

Yes i am sure it does...even the note 3 did.

I appreciate that, but the same can be said for the Droid Maxx and original X, and the new ones don't do it. Forgive me for being anal, but do you have one in hand or were you saying that just b/c of the Note 3?

Voice and data at the same time have been available since Verizon brought out 4g LTE service. If you're in a LTE service area (most of the country with Verizon).... Then voice goes over the old CDMA network and data is on lte. And you can use both at the same time.
VoLTE is different, and is being rolled out to devices.

Only on Android devices (most, not all), and only because they built a "dual" antenna/radio setup on the snapdragon chipsets. But for whatever reason on the new X and Turbo, they went away from that. So the only way to have that function again is with the somewhat unreliable VoLTE.
Thanks for confirming the Note 4 still can...

Was going to say. I have been able to since s3 & first time was with HTC Thunderbolt
Pretty much since lte service

The iPhone 6 do have volte but you have to enable it. The downside is that your voice quality could be impacted if your data connection sucked. Didn't sound like a feature that turns on/off automatically with all the warning messages it gave me.

Ah, iPhones! I remember having a Blackberry, they both have/had potential. Just lack on progressing in innovation & giving users opportunity to help them grow.

It's due to the antenna setup.
In order for voice and data to function simultaneously on Verizon without VoLTE, there has to be two separate antennas - one for CDMA and one for LTE. Some of Verizon's recent devices (such as the Note Edge and Droid Turbo) only have one shared antenna, meaning that only CDMA or LTE can run, not both. It's certainly frustrating for many users, and while Verizon's reasoning for this makes some sense, it's still not great at this time for those who use the feature. With the network moving toward LTE-only with VoLTE, Verizon's reasoning is in part based on this - why include additional hardware at additional cost and space (a second antenna) to run voice and data simultaneously when the same feature can be achieved with one antenna and VoLTE? Of course, VoLTE isn't completely ready for prime time, and they're still working out issues, so for many it's not a true replacement at this point. But that's a big reason why some of Verizon's recent phones can't do simultaneous voice and data without VoLTE - Verizon is trying to pave the way for VoLTE adoption.

Which NEW phones support Voice and Data (WITHOUT) using VoLTE... I have a 2013 Moto X that supports this, and refuse to upgrade until I can find a new device that does support this -- where can I find this data? I would imagine some phone (like a Nexus 5X) might support this since it's not made specifically for Verizon? And before it gets asked, VoLTE is too unreliable for my needs --- when using it on my work iPhone 6S calls drop constantly, so I've had to disable it... but still need voice AND data at once. Any resources / sites listing which devices support this feature would be really helpful.

Simultaneous voice + data on Verizon?

I read there are some issues with the Galaxy S6 and some newer phones on Verizon being unable to do native simultaneous voice + data. I think because of a limit of the # of radios and/or antennas. What can we expect with the 5X on VZW? Thank you!

All new phones can do simultaneous voice and data only with VoLTE or while connected to WiFi. When connected to LTE (and no VoLTE) or 3G data they will drop to CDMA 1X if a call comes in. This is because they only have one antenna pathway and one radio. If they had a separate radio for LTE (like done older phones) it would drain battery almost twice as fast since mobile connection is one of your larger battery users.

Any time LTE is on the second would have to be on, or it wouldn't be able to seamlessly take the call, so that wouldn't have worked.
If your call isn't very long navigation would still work fine, it caches a bit in case of signal drop. The other option would be to download the route ahead of time, Google can do it now I think.
I have a feeling it should have VoLTE though, which would give you voice and data.

Will the same limitations be on each carrier (ie. if I switch to AT&T I still need to use VoLTE for simultaneous voice + data)? Thank you!!

Nope, the way GSM and CDMA works are different. Say you don't have VoLTE and are on an LTE connection. The tower also has a spot for you on HSPDA and GSM if on Tmo or AT&T, or on CDMA if on Sprint or Verizon. If you get a call you fallback to HSPDA or GSM. A similar thing happens on CDMA. The difference is CDMA can't do voice and data on the same connection, GSM and HSPDA can do both.

Really wish phones included a Ev radio so this would not be an issue. I wonder if the voice quality/codec on AT&T has improved over the years? Last I used them their voice quality was far inferior to VZW. May be time to consider a carrier switch.

I've not had problems with voice quality, the few times I call on AT&T. They weren't as good as Sprint (their new network has simply amazing voice quality, and data was OK lol).
Mostly I use Google voice via hangouts to make calls, so the network data is more important then voice quality.

All new phones can do simultaneous voice and data only with VoLTE or while connected to WiFi. When connected to LTE (and no VoLTE) or 3G data they will drop to CDMA 1X if a call comes in. This is because they only have one antenna pathway and one radio. If they had a separate radio for LTE (like done older phones) it would drain battery almost twice as fast since mobile connection is one of your larger battery users.

How new? My S4 gets simultaneous voice/data on lte, but not on 3g. Are you sure you're right about this?

Well, the S4 is not a new phone. And yes I'm certain without advanced calling (or VoLTE) you will not have voice and data on LTE at the same time.

Something I'm just realizing...I have a lot of friends and offices that have cell phone amplifier / extender systems that only repeat 3G not LTE. With no 3G radio this phone will be only able to do 1x for voice/data?! I think its also crazy that pure data devices such as the MiFi/personal hotspots still include ability to do EvDo Rev A yet phones don't!

The S4 had extra antennas unlike the newer phones because of VoLTE. The S4 had both radios on at the same time which eats more battery on a call with VoLTE you have improved battery life during a call and do both at the same time. The move was intentional to save costs as well as battery life in the long run.

I just got my Nexus 5X up and running on verizon. With my Galaxy Nexus I was about to take a phone call while tethering, but can't do that on this phone. Is there a fix for this? It's kind of a bummer because I tether often and take phone calls.
Edit: (12/18/2015) I figured it out. Chatted with VZW tech support to enable HD voice feature, and made sure "enhanced LTE mode" was on in settings. Voice+Data work simultaneously now!
Update: (1/19/2016) I have still intermittently had issues with simultaneously voice+data. I started to wonder if it could depend on who you are calling or what tower you are connected to. I powered down my phone and pulled the sim card for a few seconds, then rebooted and it worked again.
