ZenSim eSIM Data Plans for United States of America

ZenSim does not provide a truly unlimited data eSIM solution for the United States of America. The plans that carry the “Unlimited” label actually offer a fixed high‑speed allowance of 3GB per day; after that limit the data speed is reduced, which means the plan is capped rather than unlimited.

Travelers who need larger data bundles can choose from ZenSim’s fixed‑capacity plans. For example, the 20GB plan is available for 10 days or 30 days, and a 10GB plan is also offered for either 10 days or 30 days. These fixed‑data options provide a more predictable cost structure for users who need substantial data without the daily limit applied in the so‑called unlimited plans.

ZenSim does not offer a United States of America eSIM that includes a phone number or SMS service. The United States eSIM plans from ZenSim are data‑only.

Travelers who need messaging and calling functionality can use data‑based VoIP applications such as WhatsApp, Telegram and iMessage, which operate over the data connection without requiring a traditional phone number or SMS capability.

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.
