Did you know that even a cell phone with no plan on it can still call 911? Most modern phones can still call 911 and is a great safety feature for many people. But parents please be aware of that when you give a child an old cell phone. If you leave the battery in for them to use on Wi-Fi make sure they know not to call 911 unless it is an emergency. If you give a cell phone to a toddler, please remove the battery.
