What is phone cap?

"Phone cap" typically refers to a limit or restriction on mobile phone usage, often set by service providers to manage data, calls, or text messaging. This cap can involve a maximum amount of data that can be used within a billing cycle or may pertain to specific features like international calls. Exceeding these limits often results in additional charges or reduced service quality. In some contexts, it may also refer to accessories designed to protect phone ports or connectors.
