Swisscom vs Salt vs Sunrise International Plans vs eSIM — Which Is Best for Swiss Travellers?
Before your next trip abroad, you have a decision to make: use your Swiss carrier's international roaming option, or switch to a travel eSIM. Swisscom, Salt, and Sunrise all offer international roaming — but the costs are significant, and unlike EU residents, Swiss travellers have no regulatory protection against these charges even in neighbouring EU countries. This guide breaks down every option side by side so you can make the right call before you fly.

EU citizens travelling within the EU pay no roaming surcharges — their home plan rates apply. Swiss residents are not covered by this regulation. When you travel to France, Germany, Italy, Spain, or any other EU country, Swisscom, Salt, and Sunrise can charge full international roaming rates. This makes a travel eSIM even more valuable for Swiss travellers than for EU residents.
Breaking Down Each Swiss Carrier's International Option
Swisscom International Roaming — CHF 5–15/day
Swisscom is Switzerland's largest carrier and offers international roaming in 200+ destinations. Europe roaming costs CHF 5–10 per day; long-haul destinations like Southeast Asia, Japan, and the USA cost CHF 10–15 per day. The charge applies automatically the moment you use your phone abroad — even for a background app refresh.
Swisscom applies data caps on roaming — your roaming data is limited to your Swiss plan's data allowance, which may be throttled once exceeded.
Verdict: Switzerland's most reliable network but its most expensive roaming option. A 14-day Europe trip costs CHF 70–140 in day pass fees. A 10-day Bali trip costs CHF 100–150 — before any other travel expenses.
Salt International Roaming — CHF 3–12/day
Salt offers slightly more competitive international roaming rates than Swisscom and Sunrise, with Europe roaming from CHF 3–8/day and long-haul from CHF 8–12/day. Coverage is more limited than Swisscom in some destinations. Data caps and fair use limits apply on roaming.
Verdict: The most affordable Swiss carrier roaming option, but still significantly more expensive than a travel eSIM for any trip longer than a few days. A 14-day Europe trip still costs CHF 42–112 with Salt.
Sunrise International Roaming — CHF 5–15/day
Sunrise charges the same rates as Swisscom for international roaming — CHF 5–10/day in Europe and CHF 10–15/day for long-haul destinations. Coverage is comparable to Swisscom in most popular destinations. Data caps apply on roaming.
Verdict: No pricing advantage over Swisscom. For any trip of 3 days or more, a travel eSIM is significantly cheaper than Sunrise roaming.
AloOui Travel eSIM — From $3.54 USD
An AloOui eSIM gives you a local data plan in your destination country at a fixed price. Full 4G/5G speeds, hotspot sharing included, instant QR delivery by email, no ID required. Your Swiss number stays active on your primary SIM for calls and texts.
Verdict: The best value option for any international trip. A 14-day Europe trip costs from $7.08 USD with AloOui vs CHF 70–140 with Swisscom or Sunrise. A 10-day Bali trip costs from $7.34 USD vs CHF 100–150 with Swiss carriers. The savings are substantial on every trip.
When Does a Swiss Carrier Roaming Plan Make Sense?
In fairness, there are situations where sticking with your carrier is the right call:
- Trips of 1 to 2 days — the setup time for an eSIM may not be worth it for a single overnight trip
- Emergency use only — if you only need your phone for occasional calls and minimal data, a day pass may be acceptable
- Corporate accounts — some business plans include international coverage at reduced or no extra cost
For any trip of 3 days or more — including a European city break, a Bali holiday, or a Japan trip — a travel eSIM will almost always be significantly cheaper.

Frequently Asked Questions
Is AloOui eSIM cheaper than Swisscom's international roaming?
Yes, significantly. Swisscom charges CHF 10–15 per day for long-haul roaming. A 10-day Bali trip costs CHF 100–150 with Swisscom. AloOui's Indonesia eSIM covers 7 days for $5.14 USD — a fraction of the Swisscom cost for the same trip.
Why do Swiss travellers pay roaming charges in EU countries?
EU roaming regulations only protect EU citizens. Switzerland is not an EU member, so Swiss residents are not covered. Swisscom, Salt, and Sunrise can charge full international roaming rates in France, Germany, Italy, and all other EU countries — the same as any non-EU destination.
Can I keep my Swiss number while using AloOui abroad?
Yes. Your Swiss number stays active on your primary SIM slot for calls and texts. AloOui handles data on a second eSIM slot. Both run simultaneously — you do not lose access to your Swiss number.
Do I need to cancel my Swiss carrier plan to use AloOui?
No. AloOui runs alongside your existing Swiss carrier plan. You keep your Swiss number and plan active — you simply disable data roaming on your Swiss SIM and use AloOui for data while abroad.
How quickly do I receive my AloOui eSIM after purchase?
Instantly. Your QR code is delivered by email within seconds of purchase, 24 hours a day. No waiting, no store visit, no ID required.
