RedSim does not offer a truly unlimited data plan for North America. All of its North America offerings provide a fixed amount of high‑speed data, either a daily limit or a total data cap, after which the speed drops to 1 Mbps. For example, the North America Unlimited 30 Days plan gives 3 GB of high‑speed data each day for 30 days, then throttles to 1 Mbps until the plan ends.
If a traveler needs a larger data allowance, RedSim offers fixed data plans such as the North America 50 GB 30 Days or the North America 20 GB 30 Days plans, which provide a larger total amount of high‑speed data over a 30‑day validity period. These fixed plans can be more cost effective for most users, unless the user expects to consume data beyond the provided limit.
