eSIMCard’s plans that carry the label “Unlimited” actually provide only a limited amount of high‑speed data, after which the connection speed is throttled. For example, the Unlimited eSIM Data For 3 Days in Tanzania gives 2 GB per day and reduces speed to 2000 kbps once that daily limit is reached. The same naming is used for plans that offer 1 GB per day, but all are capped at a fixed data amount before throttling occurs.
Because of this, travelers who need large data volumes may find eSIMCard’s fixed‑data plans more suitable. The directory lists a 100 GB plan valid for 180 days and a 25 GB plan valid for 30 days, among other non‑throttled options. Choosing a fixed‑data plan can be more cost effective for heavy data users, since the high‑speed allowance is not subject to a daily cap.
