T-Mobile's VoLTE rollout is continuing full steam ahead, and today, the Uncarrier is giving more customers access to it thanks to a new software update for LG's mammoth G Flex.

Beginning November 17, the LG G Flex will have a software update to Android KitKat 4.4.2/SWV20s that turn on VoLTE services via OTA over Wi-Fi in available VoLTE markets only. For devices not in VoLTE markets, the update will also be available via OTA via Wi-Fi or the LG Mobile Support Tool. VoLTE capabilities are limited to markets that have had VoLTE  turned on.

In addition to VoLTE functionality, the update also enables in-flight texting via T-Mobile's partnership with Gogo. The new firmware version is SWV20s and is still Android 4.4.2/KitKat.
