China Mobile and global telcos embed AI into native 5G calling
Major telecommunications operators including China Mobile, T-Mobile US, and Deutsche Telekom are integrating AI models and Data Channel technology into native voice calling networks. This shift aims to transition traditional voice pipelines into intelligent information hubs by enabling features like real-time translation, live captions, and interactive service menus.
Key Takeaways
- China Mobile launched AI-native calling on June 15, 2026, featuring live captions and AI noise reduction.
- Data Channel technology enables visual call menus and multi-party business transactions within the standard dialer.
- T-Mobile US introduced network-side translation supporting over 80 languages for borderless communication.
- South Korea’s LG U+ earned three GLOMO awards for its ixi-O assistant’s on-device spoofed voice detection.
Why It Matters
This shift marks a strategic move by telecommunications operators to reclaim market share from over-the-top (OTT) communication apps like WhatsApp and WeChat. By embedding complex AI services like simultaneous interpretation at the network layer, telcos utilize their control over 5G-Advanced infrastructure to provide lower latency and higher security than app-based overlays. For the video ecosystem, this expands the utility of native video calling through real-time AR annotations and interactive metadata. Monitor the adoption of 5G-Advanced 'Giga Uplink' speeds, as high-bandwidth network performance is required to sustain these multi-modal AI interactions.
Additional Context
The commercial rollout of AI-integrated calling follows several years of industrial coordination through the GSMA 5G New Calling Task Force. Per GSMA (April 2024), the '5G New Calling' standard was designed to revitalize the IP Multimedia Subsystem (IMS) by adding a dedicated Data Channel (DC) alongside voice and video. This architecture allows developers to deploy 'mini-apps' within the call screen, enabling restaurant menu browsing or document sharing without interrupting the audio stream. By 2026, this vision reached maturity as operators sought to monetize their massive 5G-Advanced investments through value-added services. Global competition in this sector intensified at Mobile World Congress 2026. Deutsche Telekom debuted Magenta AI as a network-integrated assistant, which, per RCR Wireless (March 2026), uses voice as the primary interface for automated task handling, such as booking medical appointments or summarizing long conversations. Similarly, South Korean operator LG U+ focused on secure intelligence; as reported by DigitalToday (March 2026), its ixi-O service was the first to implement on-device 'Anti-Deepvoice' technology to detect tampered voices in real-time, addressing growing consumer anxiety over AI-generated fraud. The economic model for these services is also evolving from traditional data usage to token-based utility. Per Informa (July 2026), Chinese operators are specifically exploring AI token-based pricing, offering premium calling bundles for approximately $1 per month. This shift is supported by network optimizations like 'Giga Uplink,' which provides the 20 Mbps constant uplink speeds necessary for smooth AI-mediated video interactions. As carriers in other regions like Southeast Asia and the Middle East enter commercial trials, the industry is closely watching whether these native features can effectively reverse the long-term decline in voice-minutes-of-usage (MOU) seen across global markets.
