A quiet but important change is happening in India’s mobile network scene.
Users across several circles have started noticing HD Voice—once limited to calls within the same network—now appearing during calls between Reliance Jio and Bharti Airtel.
Traditionally, HD or VoLTE calls offered clear sound, faster call setup, and better stability, but only within the same network.
Cross-network calls usually dropped to narrowband voice due to older interconnect systems.
How This Works
Recent reports show the HD/VoLTE icon lighting up even during Jio-to-Airtel or Airtel-to-Jio calls.
This suggests both operators may be gradually enabling wideband audio across their networks.
For this to happen, telecom companies need upgraded IP interconnects, harmonized VoLTE signaling, and agreement on codecs.
While this is common in some global markets, India has lagged due to legacy infrastructure.
Benefits for Users
If widely rolled out, this could dramatically improve call quality for hundreds of millions of subscribers.
Jio and Airtel are the largest operators in India, so better voice quality between them would instantly impact daily communication for many users.
Other benefits include:
Reduced reliance on 2G fallback networks
Smoother calls in areas where legacy networks are shutting down
Aligning India with global IP-based calling trends
What’s Next
Neither Jio nor Airtel has officially confirmed this change yet.
Most likely, this is part of phased testing in select circles before a nationwide rollout.
This silent upgrade hints at a new era of mobile voice quality in India, where high-definition calls could soon become standard, no matter which network you are calling.
