LG Electronics on Wednesday unveiled a
smartphone that offers voice call service through the
fourth- generation (4G) long-term evolution (LTE) networks.
LG's Optimus LTE2 smartphone that supports the voice over
LTE (VoLTE) service was rolled out in Seoul through
wireless carrier LG Uplus.
The company also launched the VoLTE-supporting Connect 4G
smartphone in the United States via the U.S. mobile
operator Metro PCS.
The two smartphones added the VoLTE function to the Optimus
LTE2 and Connect 4G models that were released in May in
South Korea and in March in the U.S. respectively. LG said
that it planned to provide software upgrades for Optimus
LTE2 users who want to use the service.
The VoLTE service offers voice and video call service
through the 4G LTE networks, enabling users to enjoy
clearer quality and faster connection than the
third-generation (3G) networks, the company said.
S. Korean SK Telecom will also offer VoLTE function to the
Samsung Galaxy S3 models with a software upgrade
schedulled for release later this month in South Korea.
