Fastest route
If your phone supports eSIM, check prepaid/eSIM options before or just after arrival. A Swiss number makes apartment, bank, delivery and employer logistics easier.
What to bring
Bring a valid passport or national ID and your Swiss address/registration evidence if you already have it. Contract providers may require additional residency or payment information; prepaid is often simpler at the start.
Major providers
Swisscom, Sunrise and Salt are the main network brands. Compare current coverage, roaming and minimum contract terms directly with them; those details change too often to duplicate here.
Home internet
Check what is available at your exact address before choosing a contract. If you are moving again soon, pay attention to activation fees and minimum terms.
Our rule: when something can change — forms, fees, eligibility, schedules or provider requirements — use the source link rather than a screenshot or copied checklist.
