Esimify does not provide an unlimited data eSIM for Sierra Leone. All of the available plans have a finite data allowance, the largest being the Sierra Leone 20GB 30Days plan, which offers 20GB of data for 30 days at $182.99 USD. Another common option is the Sierra Leone 10GB 30Days plan, which gives 10GB of data for 30 days for $97.99 USD.
Choosing a fixed data plan can be more economical for most travelers, unless you expect to consume an exceptionally high volume of data. These plans are available for purchase through Esimify, and the data is valid for the specified number of days after activation.
