Before deciding the need for a VPN, first, know what a VPN is.

What is a VPN?
A Virtual private network helps you to connect with blocked websites when you go online. Using VPN provides you security in a way that you cannot be digitally traced whether you are connecting by your mobile or other devices.
VPN has the following supportive facts:

VPN helps you maintain your right to privacy
VPN conserves your privacy right because when you connect with VPN, it stops even very fundamental websites that can reveal your data by keeping your web browsing secure. One can shield their web activity from others by using a VPN, but still browsing history keep showing the IP address.

Bypass a Restrictive Network
VPN helps cope with restrictive sites because it uses the bypass mechanism, and bypass is a flaw in the security system that allows the user to access the restricted sites or network. Some sites are banned due to some security reasons like some sites are not suitable for children, but one can access that site illegally that is not fair at all.

Better Protections on Public Wi-Fi Use
Public sites face the main hurdle of security issues in their network connection. To cope with this situation, VPN provides a blanket of security in local areas.

Access All the Netflix Content
Access full streaming content from anywhere. To be clear, I do not recommend piracy, but there are reported restrictions on Netflix users in different locations (usually outside the United States) where the content licensing varies. From everything I have read, Netflix is on top of these uses, but subscribers keep trying to get to the material that is not allowed in a particular place. Other streaming examples are not illegal that you may prefer to work around.

Better (VOIP) Phone Calls
Voice over IP is a low-cost mode of phone calls, but like its low price, its quality is also cheap as this site is not reliable, but it can be hacked anytime, and it is not that secure as a VPN.

Google Is Watching All Your Digital Moves
Google helps a lot in different searching patterns because google is a search engine; it provides various advertisements and specialized knowledge about the thing you searched in the search bar. But apart from this, google saves our special moves in its history centers.

When you're a remote worker or a student
VPN is a valuable network that the office bearers or other employees can use in remote working in which they can connect with the company and from their home place. A VPN secures this connection, and by this, emails and phone calls are secured.
