JamboSim eSIM Data Plans for United States of America

JamboSim does not provide a truly unlimited high‑speed data eSIM for the United States of America. The plans branded “Unlimited” offer 3GB of data per day and throttle the connection to 1000kbps once the daily quota is reached. Travelers who require more data without speed reduction can instead choose from fixed‑data packages such as the 50GB plan for 30 days, which delivers a larger data allowance and maintains the advertised speed. The 20GB plans for 30 days and 15 days also provide higher data limits without the daily cap, offering a more cost‑effective option for users who need substantial data usage while traveling.

JamboSim supplies United States of America eSIM plans that include a local phone number with outbound voice calls and outbound short‑message service (SMS) capabilities. The available plans start at $4.99 for a 1GB data allotment valid for 3 days and extend to $101.99 for a 20GB data bundle valid for 365 days, with intermediary options such as 5GB for 30 days at $9.99 or 10GB for 7 days at $12.99. All of these plans use the US dialing code +1, indicating that the phone number assigned is a domestic United States number. Because SMS and voice services are limited to outgoing use, callers will not receive inbound voice calls or SMS messages on these numbers. Travelers who need specific call or text reception capabilities should verify the exact terms directly with JamboSim.

JamboSim provides 27 single‑country data plans that target the United States, along with 30 multi‑country plans that include coverage in the United States. These plans vary in price from about $1.99 to $101.99 and in data allowance from 200 MB to 50 GB, with validity periods ranging from 3 to 365 days. The single‑country options are primarily fixed data caps, while the multi‑country offerings combine fixed amounts with daily data limits on some packages, giving travelers flexibility when choosing how much data they need while traveling.
