EU Roaming Ready
Avoid Swisscom's 59.90 CHF for 10GB EU roaming — Roami includes EU at no extra cost
Switzerland eSIM vs Local Prepaid SIM: Which Should You Choose for the Alps?
Avoid Swisscom's Expensive EU Roaming
Switzerland is not in the EU. Swisscom charges 6.90 CHF for 500MB and 59.90 CHF for 10GB EU roaming. Roami eSIM includes EU at no extra cost — a saving of up to 60 CHF for a two-week trip with EU travel.
No Surprise Fees in Liechtenstein
Sunrise has no network in Liechtenstein, charging 1 CHF/MB roaming. Roami eSIM includes Liechtenstein in its coverage — no surprise bills.
Keep Your Home SIM Active
Physical SIM requires removing your home SIM, risking missed bank verification codes. Roami eSIM works alongside your home SIM, keeping your number active for calls and SMS — essential for 2FA codes.
Eliminate Sunk Cost from Fixed Plans
Swisscom's Prepaid Flat 7 costs 20 CHF for 7 days; Lyca's Surf UL is 19 CHF for 28 days. For a 3-day trip, you waste over 50%. Roami offers 3-day plans from $1.99 — pay for exactly your trip length.

Will my eSIM work in the Swiss Alps — Jungfraujoch, Zermatt, Interlaken?
Yes — Swisscom and Sunrise have extensive Alpine coverage. At Jungfraujoch (3,454m), you’ll get 4G/5G at the summit and viewing platforms. Zermatt (Matterhorn) has full 5G coverage in town and surrounding mountain areas. Interlaken and Grindelwald have strong 5G. The only dead zones are tunnels (especially on the Jungfrau Railway) and deep valleys — download offline maps as a backup. Your Roami eSIM auto-connects to the strongest Alpine carrier. -
Can I use my Switzerland eSIM in EU countries like France, Italy, or Germany?
Yes — Roami includes EU roaming at no extra cost. This is a huge advantage over Swiss local SIMs: Swisscom charges 6.90 CHF for 500MB and 59.90 CHF for 10GB of EU roaming. Sunrise charges 1 CHF/MB in Liechtenstein. With Roami, your plan works across Switzerland and the EU seamlessly — no surprise fees, no add-ons. -
Does the eSIM work on SBB trains and the Glacier Express? What about tunnels?
Yes — Swisscom has dedicated infrastructure along all major SBB routes. You’ll have 4G/5G for most of the journey on the Glacier Express, Bernina Express, and Zurich–Geneva routes. Tunnels (e.g., Gotthard Base Tunnel, 57km) are the only extended dead zones — signal drops for 10-20 minutes in long tunnels, then reconnects automatically. Your Roami eSIM will pick up the strongest carrier as the train moves. -
Why is the Switzerland eSIM more expensive than other countries?
Switzerland is one of the most expensive countries for mobile data globally. Swisscom’s 7-day prepaid plan costs 20 CHF (~23 USD) for just 7 days. Local MVNOs like Lyca Mobile charge 19 CHF for 28 days — which wastes 75% of value for a short trip. Roami offers plans starting from $1.99 for 3 days — you’re actually saving 70-90% compared to Swiss local options while getting better flexibility. -
Do I need to show my passport or register my ID for a Switzerland eSIM?
No Swiss ID or passport registration required at purchase. Unlike Swisscom, Sunrise, and Aldi Suisse — which require in-store passport checks and can take hours or even 72 hours to activate — Roami’s data-only eSIM is delivered instantly with zero identity verification. Just buy online, scan the QR code, and you’re connected within 5 minutes. -
Can I get a Switzerland eSIM without spending too much?
Absolutely. Roami’s Switzerland eSIM plans start from as low as $1.99. The 5GB/15-day option ($5.99) is the most popular among travelers — it comfortably handles SBB schedules, Google Maps, WhatsApp, Instagram, and sharing Alpine photos with family. If you’re a heavy data user, the 10GB ($9.99) or 20GB ($18.99) plans give you peace of mind. Skipping the Swisscom airport counter saves you time and money — no queuing at Zurich Airport after a long flight. -
How does Roami compare to local Swisscom or Sunrise prepaid SIMs?
Roami offers better flexibility and value for regular travelers: (1) Swisscom charges 20 CHF for 7 days, Roami starts at $1.99 for 3 days; (2) Swisscom EU roaming costs 6.90 CHF for 500MB, Roami includes EU roaming; (3) Swisscom requires passport registration in-store, Roami is digital; (4) Lyca Mobile bans tethering, Roami allows full hotspot sharing; (5) Salt Mobile requires buying data packs on its network only, Roami accepts all global payment methods. For most travelers, Roami is simpler and cheaper. -
What if I accidentally delete my Switzerland eSIM before my trip?
Simply log in to your Roami account to fetch the QR code again, which takes about a minute. Keeping a screenshot or PDF from the original email helps too. -
When does the validity period of my Switzerland eSIM start?
The plan validity starts when you connect to a local network in Switzerland, not when you buy or install it. So you can purchase and install weeks before your trip without losing any plan days. A 7-day plan gives you 7 full days from first connection. -
Is Switzerland eSIM activation complicated? What do I need to do?
Buy online and your QR code arrives by email in about five minutes. Scan it under Settings > Cellular to install the eSIM before you fly, then switch the line on when you land in Switzerland. Activation is automatic and available 24/7 — no store visit, no paperwork and no waiting window. -
How much does a Switzerland eSIM cost, and which plan should I pick?
Prices for a Switzerland eSIM begin at $1.99 and scale up with data and duration. A 7-day plan covers most city breaks, while 15- and 30-day plans make sense for longer stays. You pay once, up front, on Swisscom and Sunrise — no contract, no auto-renewal and nothing owed after your trip. -
Does the Switzerland unlimited eSIM throttle speed after a certain amount?
Unlimited means you are not counting gigabytes. Speeds stay high for typical travel use on Swisscom and Sunrise — maps, messaging, streaming and video calls — across the validity period. If your trip is data-heavy, it removes the risk of topping up mid-journey.
