What makes a good Switzerland eSIM?
- Networks and 5G: Check which networks the eSIM uses before you buy. eSIMology's plans run on Salt and Sunrise, with 5G where the network offers it.
- Plan size: Work out how much data you'll use. Fixed plans run from 100 MB for 7 days to 50 GB for 180 days, and most plans can be topped up. For a seven-day trip, light use (about 1.8 GB in all) suits 2 GB for 15 days, standard use (about 4.9 GB) suits 5 GB for 30 days, and heavy use (about 12.6 GB) suits 2 GB a day for 7 days. Not sure? Start with how much data you need.
- Speed after a daily allowance: eSIMology prints the speed on every plan: 512 Kbps once the daily allowance is used up. Heavy daily users can choose from 500 MB a day up to 10 GB a day.
- Route and top-ups: eSIMology's data reaches the internet via France, the Netherlands or the United Kingdom. You check data left and top up on a web page, with no app to install.
Which Switzerland eSIM plan fits your trip: fixed GB or a daily allowance?
- A 3-day city break in Zurich or Geneva: light use fits 500 MB a day for 3 days. For standard use, 2 GB for 15 days leaves room to spare. Not sure how much you need? Check our data guide.
- A week of walking between Lucerne and Interlaken: standard use suits 5 GB for 30 days, and heavy use fits 2 GB a day for 7 days. Most plans can be topped up. Uber and WhatsApp are the local ride and messaging apps.
- Two weeks in Zermatt, using data every day: 2 GB a day for 15 days is the heavy-use plan. Once that day's allowance runs out, speed drops to 512 Kbps.
- Heavy users on longer trips: pick eSIMology's 10 GB a day allowance or a bigger fixed plan. Holafly sells unlimited plans by the day for 3 to 30 days, and Saily for 3 to 365 days.
