Yesterday, T-Mobile switched its VoLTE service on in Seattle. Alongside the big “switch on”, T-Mo announced that three of its handsets would receive software updates, allowing them to take advantage of VoLTE: Galaxy Note 3, Galaxy Light and LG G Flex. Some in the comments were stating that the software update wasn’t showing up immediately after it had been announced by T-Mo. But it did eventually show up yesterday.
If you haven’t already done so, you can update your devices now.
If you have a Note 3, Galaxy Light or G FLex, you should have received a notification informing you of the update. If not, check manually in your settings menu. Of course, if you’re not in Seattle, then this update isn’t entirely necessary.
