nextSIM does not provide a truly unlimited high‑speed data eSIM for Argentina. All plans that carry the word “Unlimited” in the name actually include a fixed data allowance: for example, an eSIM Unlimited Standard 1 Day Argentina grants 1GB of high‑speed data and after the 1GB is used the speed drops to 512kbps; the eSIM Unlimited Plus 1 Day Argentina offers 2GB before the speed is throttled to 2000kbps. Thus, the data is capped and the network speed is reduced once the limit is reached.
Travelers who need more data can choose from nextSIM’s fixed‑data plans that are not labeled unlimited but provide larger amounts of high‑speed data. For instance, the eSIM GLOBAL 50GB 30Days Premium plan gives 50GB of data for 30 days at no speed reduction and is available for Argentina, as is the eSIM South America 20GB 30Days Economy plan. These plans can be more cost‑effective for to heavy data use compared with a limited “unlimited” plan.
