  • Multi-SIM functionality – Have two active plans, like personal and business numbers, on a single device.

  • Airalo: Airalo offers pay-as-you-go eSIM plans with no contracts or monthly fees. Their Swiss plans start at €9 for 1GB of data, going up to €29 for 10GB. Additional data can be added at €3/GB.

Data Roaming Costs

One of the biggest benefits of using an eSIM when traveling internationally is avoiding expensive roaming charges.

With a physical SIM card, your phone connects to local networks as you travel, and you get charged international roaming rates, which are usually very high—often €1-2 per MB of data! These charges add up extremely quickly, making data usage very costly.

eSIM allows you to bypass international roaming completely. Since your plan is managed via software, your same data allowance and rates apply even when traveling abroad. So you can use data as needed without racking up huge roaming fees.

For example, say you have a 10GB monthly data plan in Switzerland for €20. With an eSIM like Airalo, N,omad, or GigSky, you get that same 10GB of data to use when traveling in the EU or worldwide for no extra roaming charges.

This makes travel much easier and more affordable. You don’t have to hunt for local SIM cards at every destination or carefully limit data usage to avoid bill shock when you get home. With an eSIM, you have seamless connectivity anywhere in the world for one predictable price.

eSIM Performance

The performance of an eSIM can vary depending on the mobile network provider. When choosing an eSIM for use in Switzerland, here are some factors to consider regarding network coverage and speeds:

  • Swisscom has the best overall coverage in Switzerland, providing service to 99% of the population. With extensive 4G and 4G+ networks, Swisscom customers can expect fast data speeds and reliable service nationwide.

  • Sunrise has the second-best coverage, reaching 96% of the population, primarily in urban areas. Sunrise has focused on deploying advanced 4G and LTE networks that deliver speeds up to 300 Mbps. However, coverage can be spotty in rural locations.

  • Salt Mobile has the third-largest network in Switzerland, covering 89% of the population. While speeds can reach peak rates of up to 150 Mbps, real-world speeds are often slower compared to Swisscom and Sunrise. Connectivity can be inconsistent when traveling outside the main transportation corridors.

  • Lebara, a popular eSIM provider for travelers, uses the Sunrise network in Switzerland. Speeds and coverage match those of Sunrise, with excellent service in cities but potential challenges in remote areas.

  • Other eSIM providers, like Airalo and KnowRoaming, rely on local network partnerships, so speeds vary considerably across Switzerland. Performance depends on roaming agreements in place at any given location and timeframe.

When deciding on an eSIM for travel in Switzerland, Swisscom generally provides the most consistent speeds and coverage. However, eSIMs using other networks can still deliver good performance for most travel needs as long as you manage expectations in rural locales. Checking coverage maps can help choose the right eSIM provider for your destinations.


Using eSIM for Travel

eSIM technology provides many benefits for travelers visiting Switzerland. An eSIM allows you to access mobile data services without having to physically switch out SIM cards in your device. This makes traveling between countries much simpler, as you can easily connect to local networks in each destination without fumbling with different SIMs.

For travelers to Switzerland, having an eSIM set up before your trip is highly recommended. eSIM allows you to quickly get connected to a Swiss mobile network upon landing at the airport, so you can use maps and translation apps and stay connected from the moment you arrive. It also avoids the hassle of finding and purchasing a Swiss SIM card once you are in the country.

With an eSIM, you can have a data plan ready to use as soon as you turn on your phone in Switzerland. Many providers allow you to pause your domestic plan and activate your Switzerland eSIM data plan seamlessly. This means you can stay connected throughout your travels and not have to worry about any gaps in service as you move between countries.

Having an eSIM also makes it easy to switch between data plans if you travel between multiple countries on a single trip. You can set up different profiles for Switzerland, Italy, France, or any other destination you visit and activate each one with a tap on your phone. No more fumbling with physical SIM cards each time you cross a border.

The convenience of eSIM for international travel cannot be overstated. It simplifies keeping connected on the go, helps you avoid roaming fees, and gives you the flexibility to change plans as needed. For any trip to Switzerland, using an eSIM is the best option for streamlined connectivity.
