No, Avelis eSIM does not provide an unlimited data eSIM for Nauru. All of the listed plans for Nauru have a defined data cap, such as 20 GB, 10 GB, 5 GB, or 3 GB, with specified validity periods.
Travelers can choose from fixed data plans, for example the 20 GB plan valid for 30 days, the 10 GB plan also for 30 days, or the 5 GB plan for 30 days, all of which include tethering. A daily 3 GB plan is available for 1 day with a fair‑usage policy that allows additional use at reduced speed, offering a flexible option for short stays. These fixed plans can be more cost‑effective unless a user expects to consume data well beyond the capped amounts.
