AIS and DTAC have announced that VoLTE calls will be available between their networks from Tuesday October 18th.
Voice Over Long-Term Evolution is a standard for high speed wireless communication for mobile phones and data terminals.
It is voice calls over a 4G network rather than 2G or 3G. VoLTE will mean better sounding voice calls and the ability to use voice and data at the same time, among other things.
Both AIS and DTAC are expected to charge the same as for current voice calls.
