Yes, you can pay your parking, but edpnet will only charge the €0,15 cost of the outgoing and incoming text messages.
Parking charges must be paid directly to the 4411 Parking service.
If you never paid directly to 4411 (or you had a mobile subscription with Proximus, Scarlet or Orange), please create a free 4411 account. More information: https://4411.io/en-be/rates
