Which activity can increase the likelihood of exceeding your mobile data plan?

Downloading large files significantly increases the likelihood of exceeding your mobile data plan. This activity typically involves transferring a considerable amount of data at once, such as software applications, high-resolution images, videos, or large documents. Each of these can consume hundreds of megabytes or even several gigabytes, depending on the content, which quickly adds up against a limited mobile data allowance.

Other activities, while they may also use data, tend to do so at a lower rate or in a more controlled manner. For instance, streaming movies—especially in low quality—may use less data compared to their high-definition counterparts. Browsing social media generally consumes small amounts of data, as it mainly involves loading images and text, and using Wi-Fi hotspots means leveraging an external connection to save your mobile data. Therefore, among the given options, downloading large files is clearly the most significant factor for exceeding a mobile data plan.
