You might have seen the "VoLTE" icon pop up on your status bar recently. But what does it actually do?
The Old Way (CSFB)
Traditionally, when you made a call on a 4G phone, the network would "fall back" to 3G or 2G to carry your voice. This meant:
- Slower Data: Your internet would drop to 3G/2G speeds during the call.
- Setup Time: Calls took longer to connect.
The VoLTE Way
Voice over LTE sends your voice as data packets over the 4G network.
- HD Voice: Crystal clear audio.
- Instant Connect: Calls connect in under 2 seconds.
- Simultaneous Data: You can keep browsing at 4G speeds while talking.
Is your carrier ready?
All major operators in Pakistan (Jazz, Zong, Telenor, Ufone) have now enabled VoLTE in major cities. Ensure your handset settings have "VoLTE calls" enabled to experience the difference.
