Good luck to you AT&T people finding reliable LTE coverage (seriously, check your area coverage). I'm going to Verizon. This feature is not a deal breaker for me.
The LTE standard only supports packet switching with its all-IP network. Voice calls in GSM, UMTS and CDMA2000 are circuit switched, so with the adoption of LTE, carriers will have to re-engineer their voice call network.[23] Three different approaches sprang up:
VoLTE (Voice Over LTE): This approach is based on the IP Multimedia Subsystem (IMS) network, with specific profiles for control and media planes of voice service on LTE defined by GSMA in PRD IR.92. This approach results in the voice service (control and media planes) being delivered as data flows within the LTE data bearer. This means that there is no dependency on (or ultimately, requirement for) the legacy Circuit Switch voice network to be maintained.
CSFB (Circuit Switched Fallback): In this approach, LTE just provides data services, and when a voice call is to be initiated or received, it will fall back to the CS domain. When using this solution, operators just need to upgrade the MSC instead of deploying the IMS, and therefore, can provide services quickly. However, the disadvantage is longer call setup delay.
SVLTE (Simultaneous Voice and LTE): In this approach, the handset works simultaneously in the LTE and CS modes, with the LTE mode providing data services and the CS mode providing the voice service. This is a solution solely based on the handset, which does not have special requirements on the network and does not require the deployment of IMS either. The disadvantage of this solution is that the phone can become expensive with high power consumption.
What about getting directions while on a phone call? I use my phone on long trips all the time and have maps up.
Article is totally misleading and wrong.
No phone except the thunderbolt can do simultaneous voice and data on LTE.
All android phones and iPhone 5 CAN do data on LTE and voice on 3G at same time. FOr all those phones, if you lose LTE you lose data at same time capability.
The reason ATT is different and thus Iphone on ATT is cause of HSPDA spec which allows for that. Only when Verizon comes out with VoLTE will all those phones do it.
Lol... The eVil empire still is inferior. But they do put out good commercial with great spin on their capabilities.
It's a little disappointing, but not much of a surprise.
Current CDMA/LTE phones have two modems. The iPhone 5 has one.
Hey, FWIW, I live in VA's largest city, where Verizon has been selling LTE for coming up on a year (next month).Good luck to you AT&T people finding reliable LTE coverage (seriously, check your area coverage). I'm going to Verizon. This feature is not a deal breaker for me.
That really sucks. It would definitely be a deal-breaker for me if I were considering them as a carrier. People can bash AT&T all they want but I have never had bad customer service, billing problems, or issues with my voice or data failing me. I guess I'm one of the lucky few.
So what happens if you're tethering? Or navigating with the new turn-by-turn navigation in maps? Does the call go to voicemail or is the data connection interrupted to allow the call through?
This might be a problem for people who stream audio in the car, perhaps? I don't know what the limitations are for that sort of thing, but I used to have all sorts of issues with my 1st gen iPhone because I'd be listening to Pandora in the car and suddenly have missed calls pop up once I got out of the car at home.
I have been wanting to switch to Verizon for a while, but this definitely gives me pause. The reason I wanted to go to Verizon now that there was an LTE iPhone was because it allowed simultaneous voice and data. For a lot of people that might not be important, but it is something I use often.
This is the question I want answered. I experienced the exact same thing on first gen iPhone... and that would be a dealbreaker for me. If it interrupts the data connection to ring through -- that's all I care about.
Here is an article saying the exact opposite with Verizon tech support

EDIT:
I take that back - if you scroll down and look at the comments, you'll find one from verizon tech support.

For those on AT&T, who think this is a dealbreaker - how many times have you actually used voice and data at the same time?
I've been on CDMA carriers pretty much forever (with the exception of a brief fling with T-Mobile and an unlocked iPhone...which can't do simultaneous voice and data either) and I have only run into problems with this ONCE. That's more than four years of having smartphones.
I don't doubt that some people need this occasionally but it's seriously a non-issue for almost everyone. I wouldn't rule Verizon out just for this. I also wouldn't assume that a Verizon rep about knows what they're talking about either.
