No, aloSIM does not offer an unlimited data eSIM specifically for Portugal. The available options are fixed data plans with set data caps. For example, aloSIM’s 100GB plan is valid for 180 days and covers Portugal along with 34 other European countries, while a 50GB plan for Portugal is available for 30 days. These fixed plans can be more cost‑effective unless a traveler is an extremely heavy data user who would need to top up or switch plans.
