Voyasim does not offer an unlimited data eSIM for Chad. Instead, the provider sells fixed data plans that include a 20GB data cap and a validity period of either 30 days or 90 days. Examples of such plans are the Chad 20GB 30Days plan and the Global139 20GB 90Days plan, both of which give travelers a sizeable data allowance within their respective timeframes. For most travelers a fixed data plan can be more cost‑effective, although extremely heavy data users may need to consider a higher‑capacity package or additional top‑ups.
