Both are not same.
Virtual circuit is a type of Packet Switch Network. Now there is a big difference between circuit switch and packet switch network. I will assume that you know the difference.
In simple words, in packet switch, message is divided into packets of some size and sent independently. Each packet has a header. In Circuit switch, message is not divided into packets, hence no headers are required. No sequence numbers are required in circuit switching.
Therefore, there is an efficient use of bandwidth in packet switching, while the same is not true for circuit switching
Packet Switch network is of two types.
1) Virtual Circuit.
2) Datagram.
Virtual Circuit is connection oriented. For example, the 2G calls you make are based on VC. Datagram is conceptually connectionless. Your 4G calls on Jio are a good examples of it.
