eSIMCard’s plans that use the word “Unlimited” actually provide a fixed amount of high‑speed data. For example, the Unlimited eSIM Data For 1 Day in Algeria gives 1 GB of 4G data before the speed drops to 500 kbps, and the Unlimited Plus eSIM Data For 1 Day gives 2 GB before it throttles to 2000 kbps. Because of this daily cap and subsequent speed reduction, the service is not truly unlimited.
If uninterrupted, high‑speed data is required, travelers can opt for a fixed‑data plan such as the 50GB eSIM Data For 90 Days in Algeria for $247.48, or the 100GB Global (Lite) unthrottled plan for 180 days at $185.68. These offers give larger data allowances without the daily cap or speed throttling, making them a more cost‑effective choice for heavy data users.
