Can I use my eSIM for calls and texts in Berlin, or just data?

Updated May 30, 2026

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.
