Worldcitisim
Travel eSIM built by a hotel owner, not a tech company
Worldcitisim provides eSIM mobile data for international travelers in 190+ countries. You set up your eSIM before you fly. You land, and you are online. No SIM card stores, no roaming fees, no wasted time.
The difference? This was built by someone who lives the problem — not by a tech team who spotted a market trend.

The founder
Isabella Liebgott. Swedish, based in Spain.
Telecom in Sweden — operator side and sales. A travel agency in Amsterdam. A SaaS startup. Then seven years running a boutique hotel in the Colombian jungle, watching guests arrive every day without internet.
Worldcitisim sits at the intersection of the two worlds I keep coming back to: hospitality and technology. I have years in both, and I built this because the problem was obvious from the hotel side — nobody should waste the first hour of their trip trying to get online.
I love working where those worlds meet. I want to stay at the front of what technology and AI can do for travel and hospitality. I have seen firsthand how much of this industry still runs on workarounds and good intentions, and that is exactly where the opportunity is.
How eSIM works
- 1
Pick a data plan
Choose your destination country and how much data you need.
- 2
Set up the eSIM
Scan the QR code we email you. Takes about two minutes.
- 3
Land and connect
Your eSIM activates the moment your phone finds a tower.
Works in 190+ countries. Plans start at EUR 2.59. Your regular phone number stays active for calls and texts. You can share your data as a hotspot. And if something goes wrong, real people answer — not a chatbot.
For hotels and hospitality businesses
Worldcitisim works with hotels, hostels, and travel businesses to offer eSIM mobile data as a guest amenity.
- ✓5-minute setup — We send you a QR code and a pre-arrival email template for your guests.
- ✓Commission on every activation — Your recommendation earns revenue, paid monthly.
- ✓Better guest experience — Guests arrive connected instead of spending their first hour looking for a SIM card store.
- ✓Nothing to install — No app, no hardware, no extra work for your staff. Guests scan a QR code and they are online.
Most eSIM companies target travelers through ads and influencers. We work directly with the places travelers already trust: their hotel.
I built this because I spent seven years answering “what is the WiFi password?” fifteen times a day. If you run a property and want to give your guests one less thing to worry about, reach out. I am the one who answers.
