My samsung galaxy tab 3 lite sm-t111 can't make a phone call

Solution
Try starting up the tablet in "Safe Mode" and then see if it will let you make calls. If it does, then you may well have something on the device that is causing the problems. Bad app, virus, malware, etc. You would then need to find and remove the problem.

To get into "Safe Mode" please do the following.

1. First turn off the tablet.

2. Next press and hold "Power" until you see the manufacturers logo on the screen, then release the power button.

3. "Quickly" press "Volume Down" and hold it for few seconds until you see the message "Safe mode: ON" or something similar.

4. If you wanted disable it, simply repeat the steps above, and you should see "Safe Mode: OFF" rather than on.
