About Simsiz
We make staying connected abroad simple, affordable, and instant.
Simsiz was built for travellers who are tired of paying outrageous roaming fees or hunting for a local SIM card at the airport. We believe connectivity should be instant, transparent, and affordable — no matter where you are in the world.
Our mission
To give every traveller instant access to affordable mobile data in 190+ countries, delivered entirely digitally — no physical SIM, no waiting, no hidden fees.
How we work
We partner with local and regional mobile network operators worldwide to offer competitive data plans. When you purchase a plan, you receive a QR code that installs directly on your eSIM-compatible device in minutes.
Our values
- Transparency — no hidden fees, ever.
- Speed — plans activated in minutes, not days.
- Simplicity — designed for real travellers, not tech experts.
- Global reach — coverage where you actually go.
