Swisscom Roaming Guide is an Android app that offers a comprehensive overview of current rates for phone calls, SMS, and data transfer abroad. It also provides valuable tips on how to plan and prepare your trip, along with important information and telephone numbers for your stay abroad. With most of the app working offline, it can be used without internet access. However, to access all its services, including activating and purchasing roaming packages, checking tariffs, and actual roaming charges, you need to be a Swisscom mobile customer.

The app offers various features to help you save on your roaming costs, such as advice on optimizing your roaming costs and the Swisscom Cockpit, which lets you have an overview of your roaming costs and set personal limits for data roaming costs. You can also view the roaming tariffs for your Abo type, add a data package once the included volume is used up, buy attractive data packages at a click, configure call redirection to your voicemail, and manage your Multi-Device line. The app also offers tips and tricks for your next trip, such as ensuring all your telephone numbers are stored in international format, and packing a travel adapter.
