TailSim eSIM Data Plans for United States of America

TailSim does not provide a true unlimited‑data eSIM for United States of America. The plans labelled “Unlimited” give a daily allowance of 2 GB (or 1 GB for North America bundles) and after that amount is used the speed is throttled to 512 kbps. Travelers who need a higher amount of high‑speed data can choose from TailSim’s fixed data plans, such as the 50 GB plan valid for 30 days or the 20 GB plan also valid for 30 days. These fixed data plans offer a set amount of high‑speed data that must be used within their validity period.

TailSim does not provide United States of America eSIM plans that include a phone number or SMS capability. Only data‑only eSIM plans are offered for the United States of America. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that those apps are accessible in the United States of America before purchasing a plan.

TailSim offers 14 single‑country data plans and 13 multi‑country plans for the United States. The available plans span a price range from $3.99 to $86.99 and data caps between 1 GB and 50 GB. TailSim provides both fixed data amount plans, which grant a set amount of data for the entire validity period, and daily data cap plans, which allow a specified amount of data each day.
