FAQ

Can I make phone calls with these eSIMs?

Most travel eSIMs (including HOLASIM, Airalo, and Saily) are data-only profiles. You can easily make voice and video calls using internet-based apps like WhatsApp, FaceTime, or Zoom.

Can I share my data via hotspot/tethering?

Yes, fixed-data plans from HOLASIM, Airalo, and Saily generally allow unlimited hotspot sharing. Some unlimited plans from other providers may have restrictions on tethering, so check the terms before purchasing.

When should I install my Switzerland eSIM?

We recommend installing your eSIM the day before you travel while connected to your home Wi-Fi. The data plan will not activate until you connect to a supported Swiss network upon arrival.
