What is RedSim?
RedSim sells eSIMs: digital SIM cards that you install on a compatible phone instead of swapping a physical card. You buy prepaid data for a destination, receive it instantly and activate it when you need it.
RedSim publishes destination guides, including a China comparison, that explain how to choose between fixed-data and unlimited options for a short city break or a longer work trip.
Key features
- Instant digital delivery – plans arrive by QR code or through the app, so setup is quick.
- Fixed-data and unlimited options – pick a bundle for maps and messaging, or unlimited for heavy use.
- Hotspot support – share the connection with a laptop or second device.
- Usage tracking and top-ups – watch your data in real time and top up an active eSIM.
- Refunds before activation – eSIMs that have not been installed or activated can be refunded.
- China carriers – China plans can run on China Mobile and China Unicom, with 5G where available.
