 * The public library not only offers free wifi (passport or ID is required for registration) and Internet terminals, it is also Europe's largest library, it's open seven days a week from 10 a.m. to 10 p.m., has two restaurants, and it's a few minutes walk from Central Station. The perfect nomad's office.
 * 3G (UMTS), 3.5G (HSDPA)
 * You can drop by a Vodafone store and get a SIM card for €7.5 (€5 traffic included, no personal data required). Of course you'll need an unlocked phone to use it.  After that, buy a top-up of at least €10 and subscribe to Zorgeloos BloX Internet, a 30-day flat connection with no traffic restrictions, by sending an SMS to the number 4000 with the text "zorgeloos internet aan".
