The primary focus of Xiaomi Offline Communication's design is to enable short-range communication in environments without network access.

To achieve this, voice data is compressed. Its sound quality and usage scenarios are similar to those of a regular walkie-talkie, unlike SIM card calls, which depend on carrier networks and emphasize sound quality.
