MetroPCS offers world's first voice-over-LTE service with LG Connect 4G
Into Mobile

Today, MetroPCS proudly claims the title of world's first mobile carrier to launch Voice over LTE (VoLTE) services, which it will offer with a new Android-powered phone in the form of the LG Connect 4G. This move puts it one step ahead of many other carriers and literally one day ahead of South Korea's SK Telecoms, which had the mind to offer VoLTE services but planned on launching the same tomorrow. MetroPCS says the sale of its first VoLTE-capable handset happened in one of its Dallas/Fort Worth stores. Those who also want to get the LG Connect 4G Android smartphone for themselves may do so by going to one of several MetroPCS stores.

What Else You Need To Know:

- VoLTE uses packet switching technology instead circuit switching in order to handle voice calls, which means the corresponding data is being handled along with other types of data on the same IP network.

- The LG Connect 4G features a 4-inch WVGA touchscreen display, 5-megapixel camera, 1.2GHz dual-core processor, 1GB of RAM, Wi-Fi connectivity, and what appears to be Android 2.3 Gingerbread.
