JamboSim eSIM Data Plans for Sierra Leone

JamboSim does not provide a truly unlimited data eSIM for Sierra Leone. The plans that carry the word “Unlimited” in their names only allow 3 GB of high‑speed data per day for the specified number of days, after which the speed is throttled to about 1 Mbps. These are fixed‑data bundles rather than unlimited plans.

Instead, travelers can choose from JamboSim’s fixed data bundles such as the 20 GB / 30 days plan, which delivers 20 GB of high‑speed data over a month, or the 10 GB / 7 days plan for shorter trips. These fixed plans can be more cost‑effective for typical data use unless a user needs a very large amount of data with no speed reduction.

Yes, JamboSim offers eSIM plans for travelers in Sierra Leone that include a phone number and the ability to send SMS. The plans range in price from $11.99 USD for 1GB / 7 days to $105.99 USD for 20GB / 365 days and include 7, 15, 30, 60, 180, and 365‑day validity periods. All of the plans have a dialing code of +1, which is a U.S. number rather than a local Sierra Leone number. The telephony features allow outbound voice calls and outbound SMS, but they do not support inbound voice or SMS. Travelers who need specific call or messaging capabilities should confirm the exact details directly with JamboSim.

JamboSim offers 7 single‑country plans for Sierra Leone and 21 multi‑country plans that include Sierra Leone. In addition to these, 25 of their plans provide a fixed data cap while 3 feature a daily data cap, giving travelers options between a set amount of data and a data allowance that resets each day. The available plans range in price from $1.99 to $106.99 and in data size from 200 MB to 20 GB.
