No, yaySIM does not provide an unlimited data eSIM plan for Botswana. The available plans for Botswana are fixed data plans with a hard cap. For example, the GL‑120_20_30 plan gives 20 GB for 30 days and the BW_20_30 plan offers 20 GB for 30 days, both priced at $89.53 USD and $116.43 USD respectively. These fixed plans can be more cost‑effective for most travelers, especially if they need a substantial amount of data without the higher cost of an unlimited option.
