ZenSim eSIM Data Plans for United States of America

ZenSim does not offer a truly unlimited high‑speed data eSIM for the United States of America. The plans that carry “Unlimited” in their name, such as the USA Unlimited STANDARD – 10 Days and 30 Days, provide 3 GB of high‑speed data per day and are labeled with hasUnlimitedName = true; once the daily allotment is reached the speed is reduced, so the data amount is not unlimited.

Instead, ZenSim offers fixed data plans that give larger total allowances. For example, the USA 20GB – 10 Days plan gives 20 GB of data for 10 days, and the USA 10GB – 30 Days plan gives 10 GB for 30 days. Choosing a fixed‑data plan can be more cost effective unless a traveler requires constant high‑speed data without caps.

ZenSim does not provide eSIMs for the United States of America that include a phone number or SMS capability. The only options available are data‑only plans, which give high‑speed internet access without any built‑in voice or text service. Users who need to make calls or send messages can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

ZenSim offers eight single‑country data plans for the United States. The plans are split into daily data‑cap options and fixed data‑cap options: daily caps limit how much data can be used each day, whereas fixed caps provide a set amount of data that can be consumed over the validity period. Prices range from about $12 to $57, and data caps vary from 3 GB to 20 GB. Each plan is valid for 10 to 30 days, and tethering is allowed on applicable plans.
