Popular WiFi & Thẻ Sim in Thuỵ Sĩ

When traveling to Switzerland, tourists typically have several main internet connectivity options to choose from, including renting a portable WiFi device, purchasing a local physical SIM card, or using an eSIM (virtual SIM card). Portable WiFi devices are suitable for multiple users and do not require swapping out your phone's SIM card. Physical SIM cards require replacing your original card, which carries a risk of loss, but usually offer stable signals. eSIM is the most convenient as it requires no physical card and can be set up by scanning a QR code, while also allowing you to keep your original phone number. Each option has its own convenience and applicable scenarios, so you can choose based on your personal needs.

When selecting an internet plan for Switzerland, consider the duration of your trip, your estimated data usage, the number of people traveling with you, and whether your phone supports eSIM. If you need to share internet access among multiple devices, a portable WiFi device is a good choice. If convenience is a priority and your phone supports eSIM, an eSIM plan can save you the hassle of swapping physical cards. If you have a limited budget and your phone doesn't support eSIM, consider a physical SIM card. Additionally, check the network coverage in the areas you plan to visit to ensure good connectivity in cities, mountains, or on trains.

Network coverage in Switzerland's mountainous regions varies by location. At popular mountain tourist attractions such as Jungfraujoch, Matterhorn Glacier Paradise, or popular ski resorts, major telecom providers usually offer good, even 5G, network coverage. However, in more remote valleys, deep hiking trails, or when passing through long tunnels, the signal may weaken or even drop. It is advisable to download offline maps or travel information in advance when exploring mountainous areas, and to choose a telecom provider with extensive coverage, just in case.

Both eSIM and physical SIM cards offer their own conveniences. The biggest advantage of eSIM is that it eliminates the need to swap physical cards; activation is quick by scanning a QR code, and your phone can retain its original number, making it easy to receive important texts or calls, ideal for travelers seeking convenience. Physical SIM cards have wider compatibility and work with older phones that don't support eSIM. Some plans may also support hotspot sharing. If your phone supports eSIM, it's generally the more convenient choice; if not, a physical SIM card remains a reliable option.

Before heading to Switzerland, you have several ways to book a travel SIM card. The most common method is to purchase in advance through online travel platforms, such as KKday, which offers Chinese customer support and flexible cancellation policies, alleviating language barriers. You can choose to pick it up at a Taiwanese airport or have it mailed to your home. Another option is to choose an eSIM plan; after purchase, you'll receive a QR code to scan and activate upon arrival in Switzerland, saving you the time of physical pickup. Preparing in advance ensures you have internet access as soon as you arrive.

In Switzerland's Jungfrau region, popular tourist spots like Grindelwald and Wengen, as well as facilities such as the Jungfraujoch observation deck, typically have good 4G/5G network signals. This allows tourists to easily upload photos, make video calls, or check information. However, when traveling by mountain train through tunnels, or venturing deep into more remote hiking trails, network signals may temporarily weaken or drop. It is recommended to download necessary information in advance when engaging in activities in alpine areas.

Upon arriving at major international airports in Switzerland, such as Zurich Airport (ZRH) or Geneva Airport (GVA), you can buy local physical SIM cards at telecom operator stores or convenience stores within the airport. You will typically need to present your passport for registration. After purchase, store staff may assist you with installation and activation. It is recommended to complete the purchase and activation at the airport and confirm that the network is functioning properly before leaving, so you can immediately use the internet to check transportation or contact information.

When using the internet during a winter skiing trip in Switzerland, keep a few things in mind. First, low temperatures can accelerate phone battery drain, so bring a portable power bank. Second, snow activities might expose your phone to moisture, so waterproof protection is essential. For network coverage, major ski resorts, cable car stations, and along the ski slopes usually have good signals, but signals might be weaker in more remote areas. The internet is very useful for emergency contacts, checking weather or snow conditions, and instantly sharing your skiing fun.

Internet stability on trains in Switzerland is generally good, with many trains offering free Wi-Fi services. However, signal quality can vary depending on the train's route. When trains pass through tunnels, travel through deep mountain valleys, or go through more remote areas, Wi-Fi signals may weaken or temporarily drop. If you have high demands for network stability, especially for work or video calls, carrying your own rented portable WiFi device or using your own physical SIM card/eSIM will typically provide a more stable connection.

Switzerland's internet infrastructure is quite advanced. In major cities, tourist attractions, and many town areas, 4G and even 5G networks have extensive coverage and high speeds, generally sufficient to stably support high-bandwidth applications such as video calls, video streaming, and real-time navigation. However, network speed and stability may be affected when trains pass through tunnels, you are in remote mountainous areas, or in poorly signalized indoor locations. If you frequently need to make video calls, it is recommended to choose a plan with ample data and wide coverage, and try to conduct calls in areas with good signal strength.
