eSIMX does not offer an unlimited‑data eSIM for Nauru. All of the available plans for the country have a specific data limit. The largest fixed data plan on the catalogue offers 20 GB for 30 days at a price of $60.80 USD, while a 10 GB plan for 30 days costs $30.80 USD. Smaller options include 5 GB, 3 GB and 1 GB packages that are also valid for 30 days (or 7 days for the 1 GB).
Because each plan is a fixed data bundle, they can be more cost‑effective for most travelers, especially those who do not require the level of usage that would qualify them for an unlimited plan. If a user expects to consume very large amounts of data, a fixed plan may still not meet that need, but among the choices that eSIMX does provide, the 20 GB and 10 GB options are the most generous.
