Voice over LTE (VoLTE) is also known as ‘4G Voice’ or ‘4G Calling’. 4G Calling means that your phone call can be made over 4G networks. To use 4G Calling, you’ll need a VoLTE capable mobile phone, and a 4G enabled plan. This may also mean a software update to enable VoLTE on your phone. See our list of VoLTE capable phones to learn more, and what to expect with software updates.
