Understanding International Roaming in Switzerland

Before we dive into the different roaming options for business travelers in Switzerland, it’s important to understand what international roaming means.

International roaming is a service offered by mobile carriers that allows you to make/receive voice calls, send/receive text messages, and use mobile data outside the home network’s coverage area.

If roaming is disabled, you will be unable to use your network carrier’s services. However, if roaming is enabled and you don’t have a valid roaming plan, then you will be charged extra for all the services used. This includes calls received as well.

Although Switzerland is a country in Europe, it isn’t a part of the EU, meaning the EU’s “Roam Like at Home” regulations don’t apply. You must have a corporate SIM for Switzerland to ensure hassle-free mobile connectivity. There are other options as well, which we’ll discuss in the next section.

Roaming Options for Business Travelers

Switzerland has plenty of options for those visiting the country for business purposes. It is up to you to decide on one based on your requirements and duration of stay. Each option comes with its pros and cons, so it helps to do your research before finalizing one.

Roaming Plans

An international roaming plan in Switzerland is the recommended option for most business travelers. Most of these plans combine benefits like calls/texts, high-speed 5G data, and the ability to use mobile services in other countries in the EU. It is vital to read the fine print to make sure that the chosen plan meets all your requirements.

It also helps to look into the local plans, especially if you’re a subscriber of Lyca Mobile. Some plans include roaming benefits to countries like Switzerland. In such cases, the only thing the user has to do is activate the roaming option in their smartphone, which is also discussed in this article.

eSIMs

eSIMs are replacing physical SIM cards at a rapid rate. Even the recently released iPhone 17 had an eSIM-only model in select regions.

Business roaming in Switzerland is easier and more convenient with an eSIM. Individuals just have to visit the website of the mobile carrier they wish to subscribe to and follow the on-screen instructions. The entire process can be completed in a few minutes, and the eSIM will be activated almost immediately.

Lyca Mobile has some attractive eSIM-supported plans for business travelers in Switzerland, like Hello Swiss Truly UL, Hello Swiss L, and Hello Swiss Max. These plans also offer roaming benefits to countries in the EU and North America.

Local SIM Cards

A local SIM card is the recommended option for those who plan to stay for extended periods and don’t have an eSIM-supported smartphone. Like eSIM-only plans, local SIM plans also come with extra features like unlimited calls and text messages, 5G internet, and more.

You will need to submit proof of identification to get a physical SIM card. A passport works in most cases, but you can also submit the following documents.

  • Proof of address

  • Swiss work permit (a letter of confirmation from your employer)

Physical SIM cards are usually activated within a few hours. A local SIM card or an eSIM card is the way to go if your organization doesn’t provide a corporate SIM card for your Switzerland trip.

Pocket Wi-Fi

Pocket Wi-Fi refers to small, battery-powered routers that can be carried around. Also known as Mi-Fi devices, these pocket routers offer 4G/5G internet on the go.

What makes pocket Wi-Fi devices an attractive option is their ability to connect to multiple devices at the same time. Some of these rentals also offer support to other countries in the EU as well.

Pocket Wi-Fi devices are great for short stays. Rental periods can be as low as seven days. However, they can be quite expensive when compared to a corporate SIM card or an eSIM in Switzerland.

Free Wi-Fi

The last option for business travelers in Switzerland is to take advantage of the numerous free Wi-Fi spots in the country. Public spaces like bars, hotels, and restaurants also provide free Wi-Fi, which comes in handy.

However, there are a few issues that need to be addressed.

Network congestion is common in free Wi-Fi spots. This may lead to reduced browsing and downloading speeds.

Security is another concern in free Wi-Fi spots. These networks usually have questionable security measures and are often unencrypted, making it easy for hackers to intercept information that is being transmitted. Using them for work-related tasks can be quite risky.

Then there’s convenience. Not having an eSIM for Switzerland business trips or a corporate SIM means you’re left at the mercy of free Wi-Fi spots, which may not be available in all places.

Tips to Optimize Roaming for Business Travel

With the options for international roaming in Switzerland out of the way, let’s take a look at some roaming tips for business travelers in Switzerland.

  • Check Your Existing Plan: Most monthly and pay-as-you-go plans, especially from carriers like Lyca Mobile, come with international minutes, messages, and data. You may simply have to enable roaming in your phone rather than purchasing a dedicated plan.

  • Turn Off Data Roaming: If you plan to use a pocket Wi-Fi device, consider switching off the data roaming option. If the roaming option is left on, your device may connect to a local network, leading to exorbitant charges.

  • Monitor Data Usage: It’s always a good idea to monitor data usage. Roaming plans often have limited data, and it’s easy to use them up, especially if you’re streaming or downloading content. If the allocated data runs out, you may face throttled internet speeds or excessive data charges.

  • Choose an Option Based on Requirements: There are many business roaming options in Switzerland. It helps to research and find one that suits your needs, rather than randomly picking one.
