The maximum amount of data a mobile or internet plan allows before it slows or charges more.
A data cap is the ceiling on how much data your mobile or internet plan allows before it slows down or starts charging you more. Video calls and file uploads burn through data quickly, so a low cap can quietly choke your ability to work. For anyone earning online, the cap is not a detail; it is part of whether the connection is actually usable.
You buy a local SIM that looked like plenty of data, then spend your days on video calls and uploads. Partway through the month the plan hits its cap, throttles to a crawl, and your next call keeps freezing right when you need it to hold.
Video calls and uploads eat data fast, so a low cap can throttle your ability to work.

A fair use policy is the catch on plans sold as unlimited: a clause letting the provider throttle usage that far exceeds normal levels, so unlimited rarely means truly without limit.
