Verizon's, Sprint's iPhone 5S, 5C won't juggle data, voice
Just like the iPhone 5 for Verizon and Sprint, the iPhone 5S won't be able to simultaneously browse the Internet while making a call, unlike the AT&T and T-Mobile versions.
Here's one trick the iPhone 5S or
That's according to Apple, which confirmed the limitation a day after unveiling its latest flagship smartphone.
That the new iPhones won't be able to juggle voice and data isn't a surprise -- it's been a lingering drawback for all previous iPhones that ran on Verizon and Sprint's network. Verizon and Sprint's phones run on a network technology called CDMA, which can't juggle voice and data. While Verizon and Sprint have moved to LTE for faster data, that network also isn't compatible with CDMA.
The iPhone, however, can run data and voice at the same time if working off of a Wi-Fi network.
In contrast, AT&T and T-Mobile run on a technology called GSM, which alongside the more advanced LTE technology can juggle voice and data at the same time. Indeed, it was one of the key advantages that AT&T loudly touted when Verizon first began selling the iPhone and presented Apple fans with an alternative carrier.
Apple said the network technology prevents voice and data, and that it isn't a problem specific to the iPhone. But other handset manufacturers have added in separate radios that enable the simultaneous voice and data over the cellular network, though the feature isn't universally available. The HTC Thunderbolt, for instance, was able to juggle both tasks, thanks to its additional radios.
Verizon and Sprint users can look to voice over LTE as an eventual solution to the voice-data dilemma -- when the devices drop using the older cellular networks completely. But that remains a while away. Verizon, for instance, said the first voice over LTE phone won't come out until next year.
