Roamify does not provide an unlimited data eSIM for Botswana. All of the plans for that destination have a fixed data cap as shown in their Data cap column.
Travelers can choose from fixed data plans such as Botswana eSIM 100 GB for 30 days, Botswana eSIM 50 GB for 15 days, Botswana eSIM 50 GB for 30 days, Botswana eSIM 20 GB for 15 days, or Botswana eSIM 20 GB for 30 days. Selecting a fixed data plan can be more cost‑effective unless a traveler is an extremely heavy data user.
