"...even on AT&T and T-Mobile the iPhone cannot do simultaneous voice and 4G LTE data."

by Jarahawk    Sep 16, 2013, 5:01 AM

"...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.

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."
