4S eSIM eSIM Data Plans for United States of America

4S eSIM does not provide a true unlimited data plan for the United States of America. All of its United States‑based offerings are fixed data plans that specify a maximum amount of high‑speed data, after which the speed is reduced to a lower tier (for example, 1000 kbps). While the plans have large data allowances—such as United States 50GB Unlimited – 5 days and United States 30GB Unlimited – 15 days—none of them provide unlimited high‑speed data. Travelers who need more data can purchase one of these high‑data plans or buy additional data credits, but every plan has a hard cap on the amount of data available before the reduced speed applies.

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.
