Most travel eSIMs, including those from Cellesim, primarily provide mobile data for internet access in Berlin. While some premium plans might include a local number for calls/texts, the most common use is for data-driven communication via apps like WhatsApp, FaceTime, or Skype. You can still receive calls and texts to your primary number if your phone supports dual SIM functionality.
