Xiaomi 15 Now Supports Voice Calls Without Internet or Network

The Xiaomi 15 series has received the HyperOS 2 beta update (version 2.0.25.0.VOBCNXM), a significant upgrade for the flagship lineup.

The 535MB update resolves app crashes and fixes game interpolation issues, but its standout feature is Xingchen Netcom.

This revolutionary technology enables voice calls without a network, working within a 3.5km radius and penetrating up to seven walls for reliable communication in tough environments.

Introduced at the series launch in October 2024, Xingchen Netcom pushes the boundaries of smartphone connectivity.

Currently available in the internal beta, this feature is set to roll out to all users via an OTA update in December 2024, solidifying Xiaomi’s position as an innovator in flagship smartphone technology.
