Stellar eSim does not provide a true unlimited data eSIM for Argentina. All of the plans listed for Argentina have a hard data cap—ranging from 1 GB to 3 GB for the “Unlimited”‑named bundles, and up to 50 GB for the larger fixed‑data options. The “Unlimited” label in the plan names refers to a fixed data bundle that includes a set amount of high‑speed data; once that amount is used, the speed is reduced rather than the data becoming unlimited.
If a traveler needs a larger data allowance, Stellar eSim offers fixed data plans such as 50 GB for 90 days, 50 GB for 180 days, or 45 GB for 180 days. These plans provide a substantial amount of high‑speed data within a specified validity period and can be more cost‑effective for most users, unless the traveler is an extremely heavy data consumer.
