My little sister has a phone I set up for her. It has no internet browser, requires permission to download apps, no voicemail, blocks unknown callers, and turns off at 9pm with the exception of contacting family or emergency services.

Phones can be safe for kids if parent just put in the time to learn about parental safety systems and implement them.

Where there is a hole there is a way.
