Enable VoLTE to enjoy seamless connectivity and HD Calls with SLTMOBITEL

What is VoLTE?

VoLTE (Voice Over LTE) is a technology that operates on 4G network to provide uninterrupted internet connectivity and high-quality voice calls among users who have VoLTE enabled devices.

Below are the 3 major benefits you would get with VoLTE.

  • The Data connection will NOT be interrupted when receiving a voice call. Even during a voice call, customers will be able to browse internet on 4G network without falling back to 2G/3G Networks.
  • When VoLTE is enabled, Voice calls will be made using the 4G network which will enable HD and HD+ calls by significantly improving the quality of the call.
  • Shorter call set up time. VoLTE improves the call set up time significantly compared to the time taken to set up call in 4G network without enabling VoLTE.
