eSIM for Switzerland

Dial *#06#: if the screen shows an EID number, the phone supports eSIM. On iPhone you can also look for "Add eSIM" in Settings → Cellular; on Android — in Settings → Connections (or Network) → SIM manager. Or find your model in our list.

iPhone XS / XR and all newer models, Google Pixel 3 and newer, Samsung Galaxy S20 and newer plus the Z Fold and Z Flip series, and most recent flagships from Xiaomi, OPPO, Motorola and Huawei. Exceptions: iPhones sold in mainland China have no eSIM, and some budget versions of Android models skip it — check the exact model.

No. A phone locked to one carrier will not accept another provider's eSIM. Ask your carrier to unlock it before the trip — check under Settings → General → About → Carrier Lock on iPhone, or by inserting a SIM from another carrier on Android.

Buy a local physical SIM card on arrival (usually at the airport or a carrier shop, with your passport), use a pocket Wi-Fi router, or rely on your home carrier's roaming package. A local SIM is often the cheapest for long stays.

An eSIM gives you mobile data from the moment you land: no hunting for a shop at the airport, no passport registration and no roaming bills from your home carrier. You buy and install it online before the trip, and your main SIM stays in the phone for calls and texts.

A carrier-unlocked phone that supports eSIM, an internet connection to install the profile (hotel or home Wi-Fi is fine) and a bank card for payment. Not sure about your phone? Check it in a minute.

Look at four things: which local network the eSIM uses, how many gigabytes you need, how long the plan is valid and the price per GB. Compare plans for your destination side by side, or answer a few questions and we will suggest a plan.

Install it at home over Wi-Fi a day or two before departure, but switch the eSIM line on only when you land: turn on data roaming for the eSIM line and set it as the line for mobile data. Most plans start counting days from the first connection abroad, not from purchase.

Yes. Phones with eSIM work in dual-SIM mode: keep your main SIM for calls and SMS (bank codes still arrive) and use the eSIM for data. To avoid roaming charges, turn off mobile data on the main line.

Delete the eSIM profile in your phone settings (Cellular / Mobile network → the eSIM line → Delete). It does not affect your main SIM card. If you might top up the same eSIM on your next trip, you can simply switch the line off instead.

Yes, your eSIM will start working automatically after landing, as long as it’s been activated in advance and data roaming is enabled. Most providers start counting your plan from first network connection.

Yes – if your plan includes roaming or multi-country coverage. Some eSIM plans work across Europe, but always check the list of supported countries before purchasing.

No, you don’t need to register with a passport. Buying and activating an eSIM in Switzerland is fully online – just scan the QR code and you’re ready.

Some eSIM plans include voice minutes, but most are data-only. You can use WhatsApp, FaceTime, or other apps for calling over the internet.

Signal can be unstable in remote or high-altitude areas. Most towns and tourist spots have good coverage, but it’s smart to download maps offline just in case.
