Will they get data?
If it’s their first phone, consider getting them one that doesn’t have data access. This way, your child gets a little of the connection they want, with slightly less of the risks of social media and online access that comes with a smartphone. You could get them a phone with limited data on a prepay plan, or you could get them a phone with wifi access but no data at all.
There are pros and cons to all of these options, but keep in mind, your child will have to learn how to navigate the internet by themselves at some point, and the goal is to set them up to do that well, no matter where they are.
The process of coming to an agreement may actually be more important than the contract itself. Our kids need rules, but what they need much more is to know the reason behind the rules and the most important reason to communicate to your kids is that you love them.
