Sprint and Verizon iPhone 5 won't allow simultaneous voice calls and LTE data

This probably won't be much of a deal breaker for potential iPhone 5 owners, but we thought it would be good to give you, guys, a heads up, especially now that the smartphone is up for pre-order. Turns out that the iPhone 5 cannot handle voice calls and LTE data at the same time when used on a CDMA network. In other words, Verizon and Sprint iPhone 5 owners will have their LTE data cut off during calls, so their smartphone will have no internet connection unless it is connected to a Wi-Fi network. This limitation won't be present on the AT&T iPhone 5.

Now, this lack of simultaneous voice calls and LTE data probably doesn't make sense to some of you. After all, data will flow over LTE, meaning that the CDMA radio is free to handle voice calls at the same time, right? Well, not really. The thing is that the iPhone 5 uses two antennas for a single call and actively switches between them, depending on which one has better reception. Other smartphone makers use several antennas too, but while one of them is dedicated to voice calls, another one handles data connectivity.

Simply put, the lack of a dedicated antenna for LTE data in the iPhone 5 is in the bottom of all this. Thankfully, as LTE technology evolves, there is hope that the limitation will one day be a thing of the past. Sounds like e good improvement to introduce with an iPhone 5S, don't you think?

Typical Appple release it and use software patches to make it do what we said it will do at launch

no the iphone can handle it the thing is that this is a consumer device. and consumers care about battery life and the phone just working.
thats a feature power users would like to have but its heavier on the battery.
but thats why there is choices.

Idiots. Did AT&T put Apple up to this?

It's not 2010 anymore. I can talk and surf at the same time on VZW even in a 3G area.

Do you have a HTC phone by any chance?

13. roldefol posted on 14 Sep 2012, 09:44 0 0

Yep. HTC Rezound. I thought other phones could do it too with eHRPD though. Am I actually on EVDO Rev.B?

17. jenna_23 posted on 14 Sep 2012, 11:56 0 0

nope u on revA verizon doesnt have revB u can use voice and data on revA cuz like other people mentioned some verizon htc phones can use voice and data on 3G evdo revA cuz they have a separate chip for data and one for data. i wonder how come they dnt do that on there samsung, motorola, bb ,LG phones? For some reason only htc phones from verizon can use voice and data on 3G. Oh and btw if u dnt believe me verizon dnt have revB just look it up..

Thanks for telling us because that wasn't in the article.

Man I'm glad I have AT&T. No such issue there...

8. Fallout09 posted on 14 Sep 2012, 08:44 1 0

It was either Apple wanted to protect that profit margins by keeping cost down or they didn’t want to sacrifice battery life by not including an additional antenna.

9. Ric1511 posted on 14 Sep 2012, 08:50 2 0

This is tipping the scale toward the HTC Phablet or Note 2 for me, if it does in fact come out on VZW. This may not be an issue for some, but I talk and surf the web all the time.

wow, my RAZR does this now that 4G LTE is around my home.

This news will increase the sale of iPhone 5 by 200%. now you guys will ask 'how'......... The answer is that, this will make the first gen. iPhone users nostalgic, when they will remember that back in 2007, they couldn't use voice and data simultaneously, and in nostalgia, they will flock to buy iPhone 5. :)
So Verizon and sprint will have very good iPhone sale this yr. :)

Wow & some may think being an AT&T customer is a good thing, lol NEGATIVE

14. PapaSmurf posted on 14 Sep 2012, 09:47 2 0

That's a shame really. Sucks for those who already pre-ordered and thought it was possible.

15. chebner posted on 14 Sep 2012, 09:56 1 0

That's funny. I can talk and surf on 3g (don't have LTE yet so not sure about that) on my EVO 4g LTE. I think I've used that feature maybe once.

DROID DOES!

23. rallyguy posted on 15 Sep 2012, 06:36 0 0

And the Iphone is supposed to be a high end device comparable to any other device on the market right now? Ummm, I don't think so.

24. Reluctant_Human posted on 17 Sep 2012, 10:34 0 0

They will wait for the 5s to be able to do it so people will buy it. Then offer a software update to the original 5 a couple months later as we've seen with many of their products.
