An internet service plan is a subscription that provides access to the internet for homes or businesses. These plans vary in speed, data limits, and pricing, allowing users to choose one that fits their needs. Common types include DSL, cable, and fiber-optic services, each offering different performance levels. When selecting an internet service plan, consider factors like download and upload speeds, monthly costs, and any additional fees. Some plans may also include bundled services, such as television or phone services, which can provide added value. Always review the terms to understand any limitations or restrictions.
