Did you know? Don't throw away your old cell phone!
An old cell phone, even if it isn't activated through a local cellular company, can still dial 911. This makes it the perfect back-up tool for an emergency.
Just make sure it is charged!
Keep an old phone in a safe place and make sure to charge it every so often. Even better, keep a extra battery pack with the appropriate cable in your truck. That way you are prepared if you need to call 911 for help.
