Deactivating or curbing services
Manage data-intensive applications or turn them off completely. These could include location services and background updates for certain apps. You can deactivate the automatic synchronization of all your apps in your smartphone's settings.
Anticipatory download scheduling
Some services offer an offline feature. It allows you to download and store content on your mobile phone in Switzerland in advance, e.g., your Spotify playlist, or a map showing your vacation destination via Navigon.
Once an app is installed on a hardware device, it often uses less data than a costly Internet search. Therefore, we recommend that you use special apps for regularly used services, such as for local transportation or restaurant information.
If you live close to a national border, it is possible that your mobile phone automatically connects to a foreign mobile network, which leads to roaming costs. You can prevent this by manually selecting the Sunrise mobile network.
For instructions on manual network selection for the most popular mobile phones, smartphones, and tablets, please go to Hardware Support.
When you travel abroad, we recommend that you switch back to automatic network selection.
Go to your mobile phone's settings to block data roaming.
For instructions on data roaming deactivation for the most popular mobile phones, smartphones, and tablets, please go to Hardware Support.
Sunrise data alert, the multi-level alert system, is activated by default; it protects you from high charges you might otherwise incur as a result of data traffic abroad. We let you know step by step via SMS of your current data costs; this gives you complete control at any time:
1. SMS when you reach 50% of your limit
2. SMS when you reach 100% of your limit.
When you reach 100% the data traffic will be automatically blocked.
You can set/change your cost limit for data traffic in the Sunrise Roaming Cockpit in the tab “Settings” in the “Roaming Settings” section. To set/change the limit click “Change” in the section “Cost limit for data roaming”. You can change your limit any time.
If you lose your mobile phone abroad, block your SIM card immediately in My Sunrise or call our international hotline at +41 58 777 01 01 (charge applies).
Turning off your mailbox
When you are traveling abroad and you receive a message in your mailbox, you pay for the cost of the incoming call and the cost of forwarding it to your mailbox in Switzerland. This is an international standard. When you retrieve your message, you also incur a charge for calling your mailbox in Switzerland.
Simply turn off your voice mailbox at any time to make sure that you do not incur these costs: #145#
When you want to turn on your voice mailbox again: *145#
You can also adjust the settings in the Sunrise Roaming Cockpit in the tab “Settings” in the “Roaming Settings” section. To avoid costs for call forwarding to your mailbox when abroad check the checkmark “Mailbox forwarding”.
Retrieving mailbox messages
When you are abroad and want to retrieve your mailbox messages, dial +41 86 076 + the last seven digits of your phone number.
If you don't get directly to your voice mailbox, but hear your greeting instead, press pound (#), enter your 4-digit mailbox password and press the pound key (#) again. As a precaution, please memorize your mailbox password. In case you forgot your password, press the star key (*). You will receive your password via SMS shortly.
