In this area, you can buy additional packages for data, call minutes or SMS/MMS.
Without a data package, a daily basic surfing tariff of CHF 2.– applies as standard for prepaid mobiles. You can, however, deactivate this basic tariff in the menu should you wish (the three lines in the top right). Chargeable surfing will not then be possible, and you will only be able to go online when connected to a WLAN.
To increase your cost security, you need a data package to surf. This ensures you are not billed for any unexpected costs. The 10 MB basic tariff is no longer available.
