Important Wi-Fi information for all ETH members who are also Swisscom subscribers.
As part of «SWITCHconnect PWLAN – off-campus surfing» http://www.id.ethz.ch/services/list/network/net_access/off-campus_EN ETH students and staff are entitled to free Wi-Fi use from participating providers.
Following release of the iPhone 5 series, Swisscom subscribers using iPhones may automatically be diverted to the MOBILE EAPSIM network, instead of to SSID «eth» or «public». http://www.id.ethz.ch/services/list/network/wifi/index_EN
«MOBILE-EAPSIM» is a fee-incurring Swisscom service, which, depending on plan can become very expensive.
For a manual connection ETH members who are also Swisscom customers should select SSID «eth» or «public» so that data downloads are not charged to their Swisscom plan. For those who are always automatically connected to wireless, be aware that you might automatically get connected to «MOBILE-EAPSIM» even while in the ETH Zurich environment or at Swisscom hot spots such as Swiss railroad stations. To avoid being billed for heavy data traffic e.g. automatic software updates, the function «connect automatically» must be turned off.
