Ok, so, you've decided that it is now time to move on from the arrangement you've had with your child under which you loan them an "extra" cell phone for specific times and purposes and you hope they are now ready for a personal cell phone they can more or less call their own.
I've learned from my extensive work with parents that it's a really, really good idea to write down the rules. This approach led to my widely use parent-child teen driving contract. Which, I remind you, is free.
Even if it's time to allow your child to tote around his or her own phone, table computer, or other digital device, think twice about providing it without a very clear written agreement. Why write it down? For the same reason people do contracts of any kind. It communicates the seriousness with which you take all of this. It eliminates (or at least reduces) later disagreements about what you said and what you meant. It just plain works better.
Here's the text for a model agreement I've worked out. After you read it, you can download it in Word format, link below. You can make any changes you wish.
I can think of LOTS of things you could add. For example, I tend to generally focus on safety, and you might want to add items that pertain to good manners. I just don't think that's business. But, examples:
It's free. If you use it, please let me know by email. I just like to know when people use my stuff. Makes me feel useful. Also, please consider passing this website on to your friends and family.
You cannot use any material on this website, including the contract, for a commercial purpose. It's licensed for personal, non-commercial use.
Ok, here's the text. At the bottom is a link to the contract.
There you go. Now, here's the contract in Word, or actually Rich Text Format. See the file under Attachments, below.
I hope this is helpful to you. Don't forget to email to say hello.
