Unlike traditional calls that use 2G or 3G networks, VoLTE transmits voice as a data stream over LTE. This provides several benefits:

  • Instant connection: Calls connect almost instantly, without delay;
  • High sound quality: Voice is transmitted in HD quality, which provides clearer and cleaner sound;
  • Multitasking: VoLTE allows you to simultaneously talk on the phone and use the Internet without losing connection quality;
  • Less Power Consumption: VoLTE technology is more power efficient than traditional calls, which improves your smartphone’s battery life.

Typically, VoLTE does not require activation. It is automatically enabled if your smartphone and SIM card support this technology.
