How much data do you need in Switzerland?

For a typical trip to Switzerland: 1 GB covers a few days of maps, messaging and the odd lookup; 3–5 GB suits a 1–2 week trip with regular browsing and social; choose an unlimited plan if you stream, hotspot a laptop, or rely on video calls. Wi‑Fi in hotels and cafés will stretch any plan further.

Mobile networks in Switzerland

Switzerland's main mobile networks are Swisscom, Sunrise and Salt. Most travel eSIMs for Switzerland connect to one of these, so coverage matches a local SIM — 4G/LTE is widely available and 5G is live in the larger cities.

  2. Buy a Switzerland plan from a provider above before you travel.
  3. Install the eSIM by scanning the QR code or tapping the in-app install — do this on Wi‑Fi.
  4. On arrival, turn on data roaming for the eSIM line. You're online without hunting for a local SIM.
