No, RedSim does not provide a truly unlimited data eSIM for Nauru. The plans that carry the name “Unlimited” offer a fixed 3 GB per day allowance and then reduce the speed to 1 Mbps for the remainder of the day, so the data is capped.
Travelers who need high‑speed data without the daily limit can choose one of RedSim’s fixed‑data plans, such as the 20 GB plan valid for 30 days or the 10 GB plan also valid for 30 days, both providing 5G connectivity in Nauru. These plans give large data allowances for the specified validity period without the reduced speed that follows the daily limit in the “Unlimited” options.
