Airalo does not provide a true unlimited data eSIM for South Asia; the plans that are marketed as “Unlimited” actually allow 3GB of high‑speed data per day after which the speed drops to 1000kbps. For travelers who need more data without that daily cap, Airalo offers fixed data plans such as the Asialink‑100GB plan, valid for 180 days, and the Asialink‑50GB plan, valid for 30 days. These fixed data options provide larger data allowances but are not unlimited and may be more cost‑effective unless a user requires heavy, continuous data usage.
