The eSIM trick: How to save money as a German with an eSIM Switzerland and vice versa

A brief digression: Switzerland and Europe — a special relationship

Switzerland is geographically located in the heart of Europe and is closely linked economically and culturally to the surrounding countries. However, Switzerland is not a member of the European Union (EU) and is also not part of the European Economic Area (EEA), which comprises the EU member states as well as Iceland, Liechtenstein and Norway. The EEA facilitates free trade and personal mobility within these countries and often offers benefits such as lower or no roaming charges within its borders.

As Switzerland is neither a member of the EU nor the EEA, the EEA's favourable rules with regard to roaming charges do not apply. Within the EU and EEA, roaming has been introduced at domestic prices, which means that you can use your mobile phone in another EU or EEA country without paying additional fees. This means that phone calls, SMS and mobile data usage may be subject to higher costs for people traveling in Switzerland as soon as they cross the border. These roaming charges can quickly become expensive, particularly for commuters and travelers who travel regularly between Switzerland and other European countries.

Benefits of the Swiss eSIM — A dream for vacationers and commuters

But it is not just for skiers or hikers that BuddySim a game changer. Imagine living in Germany and working in Switzerland — or vice versa. Every day, you cross the border and rely on Internet in the destination country. How do you solve the problem now? Two prepaid SIM cards? Two smartphones? Two contracts? The solution is an eSIM from BuddySIM for mobile data in Switzerland.

You activate your eSIM on WiFi at home and can use mobile data in Switzerland for 30 days immediately after crossing the border. This means: No more annoying changing physical SIM cards and no more roaming charges. Whether you're a busy businessman who commutes between Zurich and Constance every day — with BuddySIM, you can use your work breaks to check emails or make video calls without having to worry about changing network providers. Or whether you're an avid outdoor fan and love exploring the Swiss Alps on weekends — your BuddySIM ensures that you always stay connected even in the most remote mountain villages. Or are you a student who lives in Freiburg and goes to university in Basel? With BuddySIM, you can surf easily.

The trick for an all-round carefree package: When you drive to Switzerland

You start in Germany and need Internet directly when crossing the border with Switzerland. Since you have to activate the eSIM in WLAN and the eSIM Switzerland only allows Internet in Switzerland, there is a smart solution for this: the eSIM Europe. You can activate them on the WLAN before you leave Germany and start the trip directly on the German network — this way, for example, you avoid being charged in the border area if your smartphone already connects to a Swiss mobile tower before you have switched over to the eSIM.

With BuddySIM's eSIM, you are well prepared and enjoy unlimited freedom when traveling between Germany and Switzerland.
