No shared hosting plan gives you truly unlimited bandwidth. Unlimited and unmetered mean the host does not bill you per gigabyte of transfer -- not that capacity is infinite. The real ceilings are CPU quotas, entry-process limits, and inode (file-count) caps enforced under a fair-use clause, and those are what decide whether your unlimited bandwidth hosting plan stays responsive at traffic. This guide maps each marketed-as-unlimited resource to the mechanism that actually caps it, with typical shared-plan ranges as of July 2026, buy-versus-skip profiles by site type and traffic, and the fine-print clauses -- fair use, inodes, and intro-versus-renewal pricing -- that sit below the marketing. Compare the caps, not the label.
