Electronic toll collection for a motorist and / or subscriber having a wireless mobile device that links the device to (a) specific vehicle(s) and billing account(s) with a service provider(s), third party(s) and or toll authority(s). When a motorist having the mobile device in the vehicle approaches and passes a “virtual” toll location(s) and / or “virtual” toll barriers(s) and / or “virtual” toll boundary(s) having a given toll a central server determines whether the motorist and / or subscriber has activated an electronic ETC service associated with the mobile device, and sends a charge transaction from the central server to a service provider(s), third party(s) and / or directly to the toll authority(s) system. After every transaction, a confirmation (which may be SMS or text, vibration, voice, audible alert, email, etc.) is sent to the mobile device and / or subscriber indicating the amount paid and the status of the account.
