Sprint's Spark Phones Don't Support Simultaneous Voice/Data
It offers faster data (which Sprint really needs) as well as more reliable voice communications and better battery life. Three very crucial pros to one con that most people won't care about anyways.
Simultaneous voice and data seems like such a big deal to a lot of people and I can't understand why. Can someone please enlighten me?
It's also downright useful if you're on a speaker phone and looking for directions or looking up some information.
I do agree though, it is an over-hyped feature. I'd tentatively lay the blame at AT&T's feet, as they trumped up the fact that they had the feature and Verizon/Sprint didn't on the iPhone 4/4S as a selling point.
I've never used my phone as a hotspot (never really needed to) but I hadn't thought of that, makes sense.
I have had to look up some information while on my phone but usually I'm in front of my computer or I just call people back after I've looked it up.
It's not that big of a deal right now. But it will become a bigger deal as technology progresses. Consider having a friend on speaker phone or bluetooth who is giving you directions somewhere, while you double check on google maps. Or maybe for business purposes you want to share a spreadsheet and get the other person's thoughts without having to end the call. That's just a couple examples, but there will continue to be more and more reasons why you would want this functionality. But the big problem here is that this is Sprint's newest and most advanced technology which represents the future of their net...
My job takes me to new cities weekly and having the ability to use google maps while on a call is AWESOME! I just used it the other day when booking a tee time on vacation. I was on the phone with my buddy while looking at Golfnow to find a time at a couple courses.
I also use my mobile hotspot frequently and having the ability to not have to have my data transmission halted every time I get a call is a major selling point!
I agree that not everybody needs this but when I saw a buddy doing this on his AT&T phone a few years back I made the switch and never looked back.
Not sure why the trolls are up in arms, welcome to 1996 and birth of CDMA.
That's why I left CDMA years ago and never looked back,
You do know that the Note 3 only does sim voice/LTE, not voice/3G, so it's inherent in the device design. Nothing Sprint "did" or "didn't do".
You'll find the same experience on Verizon devices as well.
And yes I have used voice/data, I'm routinely on the irc, and do make phone calls, nice not to have a data drop. And I do admit to many others, it isn't a big deal.
That being said, unless there is a magical way of implementing TDD and FDD radios and antenna pathing, sim voice/data will go away on CDMA carriers till voLTE is available.
Verizon does support voice/EVDO.
That is not exactly true. Simultaneous CDMA1X and EV-DO -- known as SVDO -- is not a network feature. It is a device feature. It was possible on many early LTE handsets, particularly as many of those handsets used dual basebands. But that is no longer the case. And SVDO is not supported on most/all recent handsets. For example, the VZW variant HTC One M8 allows for SVLTE but not SVDO.
And for the record, VZW is the only operator in the US still offering SVLTE devices. AT&T and T-Mobile have never offered SVLTE devices.
Are you talking about CDMA or EVDO and EVDV?
It was CDMA2000 Rev D -- otherwise known as EV-DV. VZW effectively killed it by pushing EV-DO.
Verizon phones can use data while on a phone call with 3G internet.
As I noted in another comment, VZW handset support for SVDO was true among earlier LTE handsets. But recent VZW handsets support only SVLTE. No simultaneous CDMA1X and EV-DO.
If I used my phone for business regularly, I would probably need a phone which could do both. Or else I would end up being the dumb guy in the TV commercials. "What do you mean you don't know if Bob sent you that email yet?"
While I would never consider Sprint based on the past and current network, any possibility of considering switching for their all new Spark is a no-go. I constantly am looking things up on the web while on the phone, I do often tether while on the phone, and I happen to like being able to received picture messages while on the phone vs having to wait to hang up the call like all my friends who have Sprint.
I just think its sad that my rooted HTC mytouch 3g on T-Mobile's then newly established 3G network late 09 early ...
Unnecessarily harsh comment. The technology for 4G to 3G fallback *today* for the CDMA / LTE carriers such as Sprint and Verizon does not make this easy for them. So, yes, AT&T and T-Mobile have an advantage for the moment. Early LTE devices on Sprint and Verizon (and US Cellular and MetroPCS, etc., too) could not do simultaneous voice and data either.
Sprint's Spark is stressful on the compute power and processing on the current-generation of radios in the devices, so it is not surprising that the first version of Spark devices do not allow simultaneous voice and data. And the data perf...
This is completely wrong. The very first LTE phone for Verizon the HTC Thunderbolt could not only do voice and LTE at the same time but also voice and 3G.

From a technology perspective, 3G EVDO must pause when the voice call is active. The device puts the IP session into dormancy when you make/take the voice call and then comes back from dormant mode quickly enough the delay is mostly imperceptible - but, yes, it is not a full PDP context session re-establish. With the older 2G 1XRTT devices, the delay was more perceptible. Initial session start was ...

with their lack of simultaneous voice and data.
An SVDO approach (perhaps that is what the Thunderbolt uses?) needs both the CDMA and LTE radios inside the devices to be on at the same time (and accessing different antennas, BTW).
