Where Will You Go?
From my journey to yours

I’m Swedish. I ran a hotel in Colombia for 7 years. Now I live in Spain. I know what travelers need because I’ve been on both sides — as the guest hunting for WiFi and the host watching guests struggle with roaming. That’s why I built Worldcitisim: one scan, you’re connected.
