Is 30 GB of data enough for a month?

I'm curious to know, is 30 GB of data sufficient for an entire month of usage? With the rise of streaming services, cloud-based applications, and the increasing demand for online content, it seems that data consumption has skyrocketed in recent years. Would 30 GB be enough to cater to the needs of an average user who engages in activities such as browsing the internet, streaming videos, and downloading files? Or would it be wise to opt for a higher data plan to avoid any potential overage charges?
