Unlimited data refers to a mobile or internet plan that allows users to access the internet without any restrictions on the amount of data they can use. This means that subscribers can stream videos, browse websites, and download files without worrying about hitting a data cap or incurring extra charges. Many telecommunications companies, such as Verizon and AT&T, offer unlimited data plans to attract customers who rely heavily on their devices. However, some plans may include "throttling," where speeds are reduced after a certain amount of data is used, especially during peak usage times.
