4S eSIM eSIM Data Plans for United States of America

4S eSIM does not provide a truly unlimited data eSIM for the United States of America. Plans that carry “Unlimited” in the name, such as United States 3GB Unlimited – 1 Day or United States 30GB Unlimited – 15 Days, all include a specified data cap (ranging from 3GB to 30GB) and after that limit the speed to 1000kbps.
Travelers who require large amounts of data can instead select a fixed‑data plan from 4S eSIM, such as United States 50GB – 5 Days, United States 50GB – 7 Days, or United States 50GB – 90 Days. These plans provide the full data allowance without a speed throttle, which can be more cost‑effective for heavy data users.

4S eSIM does not provide United States of America eSIM plans with a local phone number or SMS capability. The provider’s United States eSIMs are data‑only, meaning you receive high‑speed internet but no built‑in voice or text services. Travelers who require voice or message functionality 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 before purchasing a plan.

4S eSIM lists 54 single‑country data plans that include the United States, in addition to 108 multi‑country plans that cover the U.S. and other regions. Plans range from $1.85 to $199.49 and offer data from 714 MB up to 50 GB. Some options charge based on daily usage while others provide a fixed data amount for the validity period.
