simpleSIM does not provide a phone number or SMS capability on its Global (World) eSIM plans; the provider offers only data‑only options for this coverage area.
Travelers who need voice or text messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict these services, so it is advisable to confirm that the apps you rely on are accessible in the regions you plan to visit before purchasing a plan.
