As we all know, in the context of higher and higher frequency bands used, the difficulty of network coverage is increasing, take the existing 5G as an example, its single base station signal coverage is smaller, and the base station density is far more than 4G, at the same time, affected by other factors such as site selection, it is still quite difficult to achieve comprehensive and deep coverage of 5G network in residential areas, which has caused a certain impact on many users who surf the Internet and voice calls indoors.
And a few days ago released iOS18beta4 system,Updated with a new feature,That isWi-Fi call function,According to the actual test of netizens,China Telecom has added the "WiFi call" function for users in this version, with the help of WiFi call function,You can make or receive calls in areas with wireless LAN connection but poor cellular network signal or no signal。
Users can find the "Wi-Fi Calling" option in Settings -> Cellular -> China Telecom, which is turned off by default and can be turned on manually.
WIFI calling is a voice and video calling technology over a WiFi network, especially for areas with poor mobile coverage.
WiFi calling is an important advancement in modern communication technology, which leverages powerful WiFi networks to perform voice and video call tasks, showing significant advantages in places where traditional mobile signals cannot be reached or where the signal is weak. It not only improves call quality, but also solves some communication challenges in specific environments.
In fact, Apple has supported this feature for a long time, but it needs to be adapted by operators, and China Mobile and Unicom have not yet followed up. This feature is still useful in some places where the signal is not good but the WiFi is strong. While it can't completely solve the problem of poor iPhone signal, it will still improve.
