I need to know how to master reset all functions.

Turn the Master ON/OFF Switch to OFF and unplug the unit for 10 minutes. Plug the unit back in, turn the Master ON/OFF Switch to ON and if the unit reset itself like it should have, it should function properly.

Hope this helped to solve the problem. Please let me know. And Happy upcoming Mother's Day!

1.Turn the device off and back on. Most service issues are due to old, timed-out registrations that have dropped you from the network. By power-cycling the phone, a new registration is acquired and signal should be restored.
2.Perform a Master Reset. If power-cycling did not restore your service, the problem may be due to a software issue. Doing a master reset will revert the software back to factory standards, restoring your service by removing bugs that may have developed over time. Generally this is done by pressing "Menu," "Settings," "Initial Setup" and "Master Reset." However, steps may vary from device to device so refer to your user manual for different steps if needed.
3.Perform a Master Clear. If the master reset did not restore your service, the software issue at work may be severe. In this case, it is necessary to completely wipe all information from the device and install a fresh copy of the operating system using the Master Clear function. Press "Menu," "Settings," "Initial Setup" and "Master Clear." Again, steps may differ from phone to phone, so consult your user manual as needed.
4.If the software resets did not restore your service, it's possible that the cellular radio has ceased functioning correctly. Contact your carrier for repair, replacement or exchange if it is still under warranty. Your carrier can advise you of the options you may have.
