The name displayed corresponds to the partner network over which you are currently communicating. Normally your mobile phone selects a network automatically. If you wish to use special services or are near a country border, select the required partner network manually. Refer to your mobile phone user guide for more information.
Supported frequencies / Required device
Signals are transmitted in different frequencies in mobile communication. Most mobile telephony devices support the most common frequencies (for the GSM standard they are 900 and 1,800 MHz). Many devices (triband and quadband mobile phones) support additional frequencies (e.g. 850 or 1,900 MHz).
To find out which frequencies your mobile phone supports, please refer to your phone specifications or click on the following prompt. If your mobile phone does not support the required frequency, you can rent a mobile phone from our partners for the duration of your stay abroad.
The infrastructure differs in different parts of the world. It is possible that there will be no network connection in certain places. Consult the roaming table before you travel to check in which regions of a country you will have mobile phone reception and can use the listed services, and whether your mobile phone is compatible with the frequency ranges in your destination country (bi-, tri- and quadband). Coverage data is updated regularly.
Hotline telephone number / Hotline e-mail
Contact Swisscom over the phone or by e-mail if you have any problems with mobile communication over the network of the respective roaming partner.
Calls to 0800 numbers from abroad are not necessarily free of charge. With the International Calling Card, for instance, calls to the freephone number may incur additional charges.
