ChillaxSIM does not provide a truly unlimited high‑speed data plan for North America. All plans that carry the label “Unlimited” actually have a 1GB daily data cap per day; once that limit is reached, the speed is throttled to 5120 kbps. The name “Unlimited” refers only to the plan’s duration options, not to data volume.
Instead, ChillaxSIM offers fixed‑data packages for the North America region. For example, a 50GB plan is available for 30 days at $139.90 USD, a 30GB plan for 30 days costs $89.90 USD, and a 20GB plan for 30 days is priced at $78.90 USD. These plans provide high‑speed data up to the stated allowance, after which the speed drops to 128 kbps. Choosing a fixed data plan can be more cost‑effective for most travelers, especially those who are not extremely heavy data consumers.
