Surfing the internet over a mobile network can be very expensive when you're abroad, due to the roaming charges. Luckily, most hotels and many cafés, bars and restaurants offer free Wi-Fi. And in the city centre around the station, at the lakeshore and Löwenstrasse there is free public Wi-Fi. Simply search for the network 'luzerner wlan' on your device and open a browser. After you enter your phone number you will get an access code which will allow you to surf for an hour for free. You will also find the commercial Wi-Fi providers Monzoon and Swisscom all over the city. You can subscribe to their services on the start page you get on your browser once you connect to their hotspots - all you need is a credit card. Prices start at 5Sfr per day. With the Visitor Card issued for free by your hotel, you get unlimited access to the W-FI 'Free WiFi - Luzern.com' on hotspots dotted around the city, you don't even have to register separately. Ask at your hotel about it.
