Apple Reveals the iPhone 5S with Fingerprint Sensor
Verizon iPhone 5S: Can it Talk and Surf at the same time?
Where Sprint and Verizon are both 3G CDMA for voice, data, and LTE.
Sprint/Verizon 4G LTE phones can also do talk/surf under 3G/4G coverage, it's just something specific to the iPhone 5 that didn't allow it to talk/surf at the same time. I forget what it was. They're asking if this was fixed.
Essentially, Apple would have to put a third antenna in the CDMA iPhone just for this feature, and that’s just not feasible for mass production. LTE will also eventually support simultaneous talk and surf in a single radio.
Don't know if this applies to the 5S though.
To my knowledge the answer is no for Sprint or Verizon unless on WiFi because of how their CDMA technology works.
The issue is that Apple put the CDMA and LTE on the same chip. Not different chip like the other manufacturers.
For the record I said CDMA technology not 3G. I am very aware that 3G and LTE operate and different network frequencies.
I have a Tmobile phone and there are instances where I can also use Voice and data at the same time however it is not a stable connection because there are instances where the data connection drops while on call I have no idea why.
You can do a search for simultaneous voice and data for verizon and there is lots of information about it.
Apple did not want to add the expense of a second antenna which would allow the LTE radio to have it's own antenna rather than sharing the antenna between the GSM/CDMA radios and the LTE radio."

"...The iPhone switches to 3G data when simultaneous voice and data is needed because there are not separate antennas for the 4G LTE radio and the voice radio.

thats incorrect only the all AT&T iphone can do simultaneous voice and data even the iphone 5, AT&T struck a deal with apple to only allow there Iphone to do it so they could stand out(example: sprint unlimited data iphone, Verizon iphone with the most LTE coverage) I dont know if the T-mobile one can but that launched over 6months after th...
