Purchase Your SIM or eSIM
Buy a physical SIM at the airport or a store, or order an eSIM online from Holafly before your trip.
Insert or Install

Practical Tips
💡 Avoid Roaming Charges
Using a local SIM or eSIM is much cheaper than roaming with your home carrier. European Union roaming does not apply to Switzerland, as it’s not an EU member.
💡 Keep Your Home SIM Active
With an eSIM, you can keep your home SIM for calls/SMS while using Swiss data on the eSIM. This is perfect for receiving 2FA codes.
💡 Top-Up Easily
All major operators offer top-up via their websites, apps, or at convenience stores. Salt also has a handy app for managing your plan.
