Tutu eSIM does not provide an unlimited data eSIM for Nauru. All of its plans for the country are fixed‑data bundles that must be used within a set validity period. For example, there are options such as 20 GB for 30 days and 10 GB for 30 days, both of which can accommodate fairly heavy data use. The 2GB/day for 7 days plan is the highest‑volume option available, but it still enforces a daily 2 GB cap and reduces speed to 1000 kbps once that limit is reached, so it is not truly unlimited. Choosing a fixed data plan can be more cost‑effective unless a traveler expects extremely light data consumption.
