Fup

FUP is an acronym that may refer to several different concepts depending on context. The two most common uses are Fair Use Policy and follow-up.

In telecommunications and internet services, FUP stands for Fair Use Policy. This policy is imposed by many broadband and mobile providers to prevent network abuse and to protect service quality for all users on plans advertised as “unlimited” or with high data allowances. A data cap or threshold is defined, and once a user exceeds it, actions such as reduced speeds, temporary bans, or extra charges may apply. FUP is not a copyright doctrine; it is a network management rule, and its specifics—threshold level, throttling speed, and duration—vary by operator and country. Users should review the policy in their plan terms to understand when and how it is applied.

In healthcare and clinical settings, FUP most commonly stands for follow-up. It denotes contact or an appointment scheduled after an initial consultation, diagnosis, or treatment to monitor progress, reassess conditions, or collect data for outcomes. Follow-up activities are documented in patient records and may occur in person, by phone, or remotely. In research and clinical trials, "FUP" can designate a follow-up assessment at a specified time point to gather long-term outcome information.

In summary, FUP is context-dependent and can refer to network usage rules or to follow-up care or assessment. Clarity comes from the surrounding domain and the accompanying definitions in policy documents or records.
