Follow this link on the phone you would like to activate for Sprint Mobile Controls. Tap the Update button at the top of the screen. Follow the instructions and your Safely Family Utility will be upgraded to the latest version.
After installation, you must open the app to get it started. Once started, Safely Family Utility runs in the background and you can close the application on your phone.
If you're still receiving an error that Safely Family Utility is out of date, try restarting your phone by holding down the power button. You may need to tap a box that says power off on your screen. Once the phone is off, press the power button again to turn it back on.
If that doesn't work, please contact Sprint Customer Care at 1-888-211-4727.
