A private SIM plan for your car's telematics unit.
Car manufacturers switch off your connections. We switch them back. Our SIM plans are tailored specifically for TCUs compatible with systems like OpenCARWINGS, so remote climate control, charge status, and navigation data keep working — without a factory data plan.
Why a general SIM won't cut it
TCUs are picky. Most consumer and IoT SIMs don't have the required functionality for older, legacy systems. Most problems come from a need to send wakeup SMS, which usually requires sending it in special way, not available to ordinary consumer data plans.
-
TCU-matched provisioning
Each SIM is integrated with OpenCARWINGS — you don't have to worry about SMSes, we take care of that
-
No contracts
Pay for the month you use. Pause or cancel from the portal whenever the car is off the road — nothing to call in and cancel.
-
Works with self-hosted servers
Pointing your TCU at a self-hosted OpenCARWINGS instance? The connection is open for any servers — no hard-coded server addresses.
-
EU-wide coverage
Roaming across EU networks means the plan keeps working on a road trip, not just parked outside your house.
-
Usage you can see
Connection status and data usage sit right alongside your other numbers in the portal — the same place you already check.
-
