4S eSIM does not offer an unlimited data eSIM for Global (World). The provider’s Global plans are fixed‑data offerings, the largest of which is a 20GB allocation. An example is the Global 20GB – 30 days plan, priced at $82.84 USD, which covers more than 120 regions worldwide. Because all Global options are capped at 20GB, a fixed‑data plan may be more cost‑effective for travelers who do not need constant, unlimited connectivity, especially compared with providers that offer unlimited plans.
4S eSIM does not offer Global (World) eSIM plans that include a phone number or SMS capability. Global plans from 4S eSIM are data‑only, so customers use the data connection for internet access. Travelers can still communicate via VoIP applications such as WhatsApp, Telegram, and iMessage, which work over the data connection for calls and messaging.
