Data plans for this provider are automatically updated. While we strive to keep the information accurate, we cannot guarantee its completeness or accuracy. Please confirm all details on the provider's official website or app before purchasing.
4S eSIM does not provide a truly unlimited data plan for Global (World)—every plan listed has a specific data cap, even those titled “Unlimited.” For example, the Global 50GB Unlimited – 5 Days plan gives 50GB of high‑speed data, while the Global 3GB Unlimited – 1 Days plan offers only 3GB, and the Global 10GB Unlimited – 7 Days plan provides 10GB. Each of these plans applies a reduced speed of 1000kbps once the data allowance is reached.
Because the data is capped, travelers who want predictable costs often choose one of the fixed‑data plans, such as the Global 30GB – 30 Days or the Global 50GB – 90 Days options. These plans give a large data allotment without the speed cut‑back that comes with the “Unlimited”‑named plans, which can be more cost‑effective for users who need steady connectivity.
4S eSIM does not offer a Global (World) eSIM plan that includes a phone number or SMS capability. Only data‑only eSIM plans are available for Global (World) coverage.
Travelers who rely on a local phone number for calls or SMS can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or limit access to these services, so users should verify that the apps they need are accessible in the destinations they plan to visit before purchasing a plan.
