BetterRoaming does not provide an unlimited data eSIM for Sierra Leone. The only plan listed for that country is a fixed data plan that offers 1GB of high‑speed data for 7 days. This plan is a standard fixed data bundle, not a pay‑as‑you‑go option, and the data allowance is capped at 1GB.
For travelers who need more data, BetterRoaming offers other fixed data plans with larger allowances. Choosing a fixed data plan can be more cost‑effective for most users, unless the traveler is an extremely heavy data consumer who would benefit from a pay‑as‑you‑go model.
