No, eSIMsData does not provide a truly unlimited data eSIM for Argentina. Every plan listed for the country has a specified data cap and a defined validity period; the name “Unlimited” in the plan titles only denotes a daily high‑speed allowance that is followed by a reduced speed after the limit is reached.
Travelers who need more data can choose a fixed data plan with a large allowance. For example, the 100 GB 30 day plan and the 50 GB 30 day and 90 day plans give a fixed amount of high‑speed data that can be used over the stated period, and they are available for use throughout Argentina.
