Voice calls

In the last century, voice calls only stayed on telephones, mobile phones and walkie-talkies, and now they have gradually developed into a universal means of communication. Voice calls can be achieved not only by telephone, but also by chat software and even mobile phone software. It may be replaced by video calling in the near future.

On July 8, 2014, in the latest iOS 8 beta, Apple adjusted the new setting options and user interface, turned on WiFi calling for T-Mobile users, and gave developers the opportunity to test this Features.

T-Mobile iPhone users with iOS 8 beta 3 can already see WiFi calling options. The system was introduced with the latest generation of OS X 10.10 Yosemite Developer Preview earlier Monday.

Apple's final version of iOS 8 will support this feature. Like other operators' voice over WiFi solutions, this service of T-Mobile can also load call data through the local wireless network, providing a more reliable and stable link, while enhancing sound quality and extending battery life. In addition, WiFi calls can reduce the load on cellular networks, thereby reducing bandwidth pressure in densely populated areas.

According to the current agreement, T-Mobile users can directly use the WiFi call function without additional procedures. When iOS 8 is officially launched in the fall of 2014, more than 90% of T-Mobile smartphones will support this function. And Windows devices have supported this feature back in 2007. ^[1]
