Prepaid, eSIM or Subscription?

1. The three options in a nutshell

All three options give you access to the same Swiss networks (Swisscom, Sunrise, Salt) and their coverage. The main trade-offs are flexibility vs. cost, and how quickly you can get started.

2. Prepaid SIM cards

A prepaid SIM requires no contract and no credit check. You buy a SIM, load credit or a data bundle, and use your phone immediately. When your credit runs out, you top up.

Where to buy

• SBB Travelshop at major railway stations
• Provider stores (Swisscom, Sunrise, Salt)
• Large supermarkets: Migros and Coop carry prepaid SIMs from major networks
• Electronics stores (Digitec, MediaMarkt)
• Online, with SIM delivered by post

What you need

Swiss law requires identity verification when registering a SIM card. Bring a valid photo ID — a passport or EU/EEA national identity card is accepted. Some providers allow online registration with an uploaded document.

Pros and cons of prepaid

• Pro: no contract — stop at any time
• Pro: no credit check, no Swiss bank account required
• Pro: available immediately at stations and shops
• Con: typically costs more per GB than a subscription
• Con: may need regular top-ups if you use lots of data

3. eSIM options

An eSIM is a digital SIM that you activate by scanning a QR code — no physical card needed. eSIM plans are available in both prepaid and subscription form from Swiss providers.

Key points for mobile plan comparisons

• eSIM prepaid plans work like physical prepaid SIMs but are downloaded digitally.
• An eSIM subscription is the same as a physical SIM subscription — just activated differently.
• Your phone must be eSIM-compatible and ideally unlocked. Check your device specs first.
• Travel eSIMs from international providers are data-only and are a good bridge solution for the first days.

4. Post-paid subscriptions

A post-paid (monthly subscription) plan is the standard long-term choice for Swiss residents. You sign a contract, use your phone, and pay at the end of the month.

Main providers and their MVNOs

• Swisscom — largest network, widest rural coverage. MVNO: Wingo (Swisscom network, typically lower prices).
• Sunrise — excellent coverage, merged with UPC. MVNO: Yallo (Sunrise network).
• Salt — competitive pricing, good urban coverage. MVNO: Spusu (Salt network).

MVNOs typically offer lower monthly prices than the main networks, while using the same physical infrastructure. The trade-off may be in customer service responsiveness or certain premium features.

What you typically need for a subscription

• Swiss residential address
• Valid photo ID
• Swiss bank account (for SEPA direct debit) — some providers accept credit cards
• A positive credit check (providers run a check — a recent arrival with no Swiss credit history may face restrictions)

EU roaming on Swiss plans

Switzerland is not in the EU. EU roaming on your Swiss plan — i.e. how your plan works when you travel to EU countries — depends on the specific plan. Some plans include EU roaming as standard; others charge per day or per MB. Always check the roaming terms before travelling to EU countries. This is not the same as "roam like at home" rules that apply within the EU.

Contract length and cancellation

Most Swiss mobile subscriptions run for 12 or 24 months. Check the notice period (Kündigungsfrist) in your contract — typically 1–3 months. If you leave Switzerland before the contract ends, contact your provider; some offer early termination options.

6. Tips for switching providers

If you already have a Swiss mobile plan and want to switch, here are the key points:

• Check your notice period: most contracts require 1–3 months' written notice before the end of the contract or billing period. Missing this can lock you in for another full term.
• Number portability: you can keep your Swiss phone number when switching providers. This is called Rufnummernmitnahme (number portability). Your new provider usually handles the process — give them your current number and contract details.
• Check for activation fees: some new plans charge a one-time activation or SIM card fee.
• Overlap billing: if your old plan runs until the end of the month and your new plan starts on day one, you may pay briefly for both. Align start dates if possible.
• eSIM transfer: if switching to an eSIM plan, your old physical SIM will be deactivated once the eSIM is active — make sure you have the new plan confirmed and ready to activate.
