Unlike Verizon’s lineup of LTE Android smartphones, we just confirmed with the carrier that the new iPhone 5 would not support simultaneous voice and data over its LTE network.
A Verizon spokesperson told us:
“The iPhone 5 was designed to allow customers to place a voice call on the Verizon Wireless network, while simultaneously letting customers access the Internet over the WiFi.”
We confirmed with AT&T, however, that the feature will work on its GSM model of the iPhone 5. AT&T told us:
“AT&T customers can talk and surf simultaneously on the new iPhone 5.”
We know Apple is shipping the same CDMA model iPhone 5 to both Sprint and Verizon, so it is probable that Sprint’s iPhone 5 will not support simultaneous voice and data as well.
Some Android devices do simultaneous voice and data on Verizon, so it is probably Apple’s baseband processor choice that led to the situation.
Update: According to the New York Times, the change is due to Apple. An Apple spokesperson explained:

“iPhone 5 supports simultaneous voice and data on GSM-based 3G and LTE networks. It is not yet possible to do simultaneous voice and data on networks that use CDMA for voice and LTE for data in a single radio design.”
