Nowadays authentication at public wireless hotspots is still not very comfortable for normal users. Most of the hotspots provide a captive portal asking the user for credentials or his phone number to send him an One-Time Password (OTP). This is uncomfortable especially on embedded devices like mobile phones due to the small screen. Therefore the PWLAN hotspots of Swisscom provide another more comfortable authentication method called EAP-SIM, which allows for an automated hotspot login using SIM credentials.
