Devices, systems, and methods are disclosed for managing text-based services on mobile devices during the operation of a vehicle. Proactive service-controls use a time of day and location based services to determine that a mobile device is in a moving vehicle. Reactive position-awareness techniques use near-field communication (NFC) to determine that the mobile device is being operated by a user in a driver's seat of the vehicle. Upon satisfying both these determinations, specific text-based services such as messaging, browsing, etc. can be disabled by either the mobile device itself or by a network entity. The present invention can also be extended to managing other mobile device's usages in vehicles, including phone calls, online gaming, etc.
