No, WonderConnect does not offer an unlimited data eSIM for Lesotho.
Instead, WonderConnect provides several fixed data plans for Lesotho, such as a 50 GB plan valid for 30 days, a 20 GB plan for 30 days, and smaller options down to 3 GB for 30 days. These plans may be more cost effective for most travelers unless they require an extremely heavy data usage that would otherwise exceed the capped allowance.
