Voice over LTE enables voice calls to be transmitted over the 4G network. Unlike calls that operate on 2G or 3G networks, VoLTE uses the faster and more reliable 4G infrastructure, so you can use your mobile data for calling and browsing at the same time without interruption.


  • Enjoy both voice and data simultaneously; you can browse while making and receiving calls on our 4G network
  • Enjoy crystal clear and superior voice quality
  • Get instant call set up

VoLTE is available to all my.t Prepay and Postpay customers who have a VoLTE compatible smartphone that is updated with the latest device software version.
