Data Roaming: What it is and how it works in Switzerland and abroad
Data roaming allows you to use your mobile phone for internet access, calls, and text messaging outside your home country. When traveling abroad, your device connects to a local network via agreements between your mobile provider and international carriers. This ensures you remain connected but may come with additional costs depending on your plan and destination.
Understanding how data roaming works, its costs, and how to manage it effectively can help you avoid unexpected charges while staying connected during your travels.
How to add roaming to your plan?
Data and calls in roaming can be added to your plan in packages. A package is always valid in all the countries of one zone or region.
