T-Mobile launches VoLTE (not nationwide), only the Galaxy Note 3, Galaxy Light and LG G Flex support it for now


T-Mobile today started offering VoLTE (Voice over LTE) services in the Seattle area, saying that a wider rollout will follow later this year. At the moment, only three of T-Mobile’s smartphones support VoLTE: Samsung Galaxy Note 3, Samsung Galaxy Light, and LG G Flex. Users will have to update their handsets to the latest software version (released today) in order to experience VoLTE, as support for it isn't enabled by default. 

With VoLTE, T-Mobile customers will be able to use LTE data during phone calls. HD Voice is also one of the features that's usually enabled by VoLTE (although this was offered by T-Mobile even without VoLTE). Another benefit of the new technology is that it allows for faster call setup times.

AT&T should launch VoLTE services tomorrow in select markets, while Verizon intends to do it sometime later this year. MetroPCS (which is now owned by T-Mobile) was the first in the US to offer VoLTE services, starting 2012.

So what is the real benefit of VoLTE to the consumer? Video calling? We can already do that over 3G and 4G LTE networks. Seeing as how none of the carriers were in a big hurry to launch VoLTE, not even for bragging rights, it must not be that much of a benefit to them either. Just trying to figure out what the big deal is, if there is one...

If carriers can move voice to VoLTE, then the spectrum allotted for voice circuits can be refarmed for more LTE bandwidth. And a packet network is cheaper and more efficient to run than a circuit network.

N5, please? However, I wonder how this would affect battery life, since LTE uses much more power than GSM. Or would the PCS GSM radio be turned off while everything, both data and voice, go through the AWS LTE radio, potentially improving battery life?

Sooo, I can' thelp but wonder being new to T-Mobile and Seattle area, does this ONLY work if both ends have VOLTE have phones or does it just go back to regular phone switch if the other phones are on a different network, say Verizon?

Its sweet being a big city and getting the latest tech nowadays. T-Mobile is big out here in Seattle, for obvious reasons.

I hope Galaxy Light is supported by community by now. I still can't find it on XDA and CM.

I've been able to use my data while talking on my phone for a while now... Nothing helps fly by a 2 hour conference call like Facebook and Youtube videos.
