Question: what is the difference between volte and lte 4g mobile?
Answer: 4G itself is LTE (Long Term Evolution) just like 2G is EDGE and 3G is HSPA. However, VoLTE (Voice over LTE) is a feature that enables the user to make cellular voice calls even when on LTE network. If a device doesn't support VoLTE, you cannot make voice call and use LTE data at the same time.
