Lumbus does not provide a true unlimited high‑speed data eSIM for Argentina. The plans that carry the name “Argentina Unlimited” give 3GB per day of high‑speed data, and once that daily allotment is reached the speed is throttled to 1000 kbps, so the data is not unlimited.
For travelers who need more data, Lumbus offers fixed‑data plans that give large high‑speed data blocks over a set period. Examples include the 50GB plan valid for 180 days and the 30GB plan valid for 30 days. These plans provide a substantial amount of high‑speed data without the daily 3 GB cap and speed reduction.
