Roamless does not provide a truly unlimited‑data eSIM for Argentina; all of its offerings in that country are fixed data caps. The plans range from 30GB to 50GB, with prices from $148.50 to $247.50 USD for each data quantity. Each plan comes with an “Unlimited” validity period, meaning the SIM can be used for as long as the plan remains active, but it is still limited to the specified data allowance.
Choosing a fixed data plan can be more cost‑effective for most travelers unless they expect to consume very large amounts of data. For instance, the 50GB plan costs $247.50 USD, while the 30GB plan is $148.50 USD, both providing access to 3G, 4G, and LTE networks across Argentina.
