The iPhone 6 and iPhone 6 Plus are the first Apple handsets to feature Voice over LTE, or VoLTE. The service allows users to utilize 4G wideband to make phone calls instead of standard voice service.
Before getting too excited, however, know that not everyone with an iPhone 6 will be able to use VoLTE on launch day. Much depends on coverage area and whether your carrier supports the technology.
To make or receive a VoLTE call, both parties must have VoLTE-enabled devices and be in an area where VoLTE is available. For now, the coverage area for VoLTE is very small in the United States but should be growing significantly in the coming weeks and months.
AT&Ts HD Voice service is currently available in parts of Indiana, Illinois, Minnesota, and Wisconsin. The service will expandinto other locations in the coming months.
Regardless of carrier, switching between traditional voiceand VoLTE is a seamless process. This means if you or the person youre talking with travel outside an VoLTE coverage area, the call will automatically switch to standard voice service.
Apple will begin accepting online preorders for the iPhone 6 and iPhone 6 Plus beginning tomorrow, Sept. 12 at 12:01 a.m. PDT. You’ll also be able to preorder the devices at Apple retail stores and wherever iPhones are sold.
