How long will 4 mb last?

The duration that 4 MB of data will last depends on how it is used. For example, browsing simple web pages may consume about 1-2 MB per minute, while streaming music can use around 1 MB per minute. Therefore, 4 MB could last anywhere from a few minutes of browsing to around 4 minutes of music streaming. However, activities like downloading files or streaming videos will consume data much more quickly.
