RedSim does not provide a Global (World) eSIM plan that includes a phone number or SMS capability. The available Global (World) plans are data‑only, meaning you can use internet services but cannot send or receive traditional SMS or make voice calls through a local phone number.
Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging; however, the accessibility of these services can vary by country and may be restricted in some destinations. It is advisable to check that the apps you need are available before purchasing a plan.
