Rufly does not provide an unlimited‑data eSIM for Argentina. Their plans for Argentina are fixed‑data plans with a hard limit of 500MB per day.
The available options are the Argentina Unlimited 7‑Day plan, which costs $50.40 USD and provides 500MB/day at full speed, then 5 Mbps for the rest of the day, with the speed throttled to 512 Kbps after the user reaches 30 GB total. The Argentina Unlimited 30‑Day plan costs $100.81 USD, offers the same 500MB/day at full speed, and also reduces to 512 Kbps once 70 GB are used across the 30‑day period. Choosing a fixed data plan can be more cost‑effective unless a traveler requires consistently high‑speed data beyond these limits.
