MeSIM does not sell a true unlimited‑data eSIM for Argentina. All of the plans for Argentina use fixed data allowances that are applied each day of the validity period and that are capped with a reduced speed of 384 kbps once the daily allotment is exhausted. For example, the “South America‑(8) 3‑day unlimited eSIM (500MB/day high‑speed)” plan provides 500 MB of high‑speed data each day for three days, after which the connection falls to 384 kbps. Another option is the “South America‑(8) 10‑day unlimited eSIM (1GB/day high‑speed)”, which offers 1 GB per day for ten days, again throttling to the same reduced speed when the daily limit is reached. While these fixed data plans may include generous daily data limits, they are not truly unlimited and include a speed reduction after the allotted data is used.
