AeriSIM does not provide any Germany eSIM plan that includes a phone number or SMS capability. The provider offers only data‑only eSIMs for travel in Germany. Travelers who need voice or text services can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, because some destinations may block or restrict access to specific apps or VoIP services, it is advisable to confirm that the applications you rely on are accessible in Germany before purchasing a data‑only eSIM from AeriSIM.
