If you own a Galaxy S4 Mini on AT&T then there’s a new software update that you have to install today. The carrier has released a VoLTE update for this smartphone which will allow this smartphone to move beyond 3G voice calls and jump on the VoLTE network of the nation’s second largest mobile carrier. This is just one of the few devices for which AT&T has released this update in order to switch on the VoLTE functionality in these handsets.
Do bear in mind that VoLTE functionality needs carrier support which is why this update is only being released to AT&T-branded Samsung Galaxy S4 Mini handsets. Don’t expect to receive a similar update if you own an unlocked variant of this smartphone, or are on another carrier that doesn’t have a VoLTE network.
As per the official changelog today’s software update brings the VoLTE inter-op call hold feature, SIM less 911 Dialing, v4v6 for IMS PDN when users are roaming and ISIM SQN re-sync for registration on the carrier’s VoLTE network.
VoLTE allows users to make calls over the carrier’s LTE network while providing better support for simultaneous use of voice and data. The software’s file size will be up to 600MB so download only when you’re on a good internet connection with ample charge left in your AT&T Galaxy S4 Mini.
