No, WonderConnect does not offer an unlimited data eSIM for Argentina. They provide fixed data plans that are valid for a set number of days. For example, a 50GB plan is available for 30 days at $71.99 USD, and a 20GB plan is available for 30 days at $32.99 USD. These plans can be more cost‑effective for most travelers unless an extremely heavy data consumer prefers an unlimited option.
