My kids’ phones are capped at the vendor, no extraneous charges, anything that’s billable is blocked, period. No accidents, no oversights, no ridiculous ringtone expenses.

It's good to know that those services are available. My son is way too young for his own phone but I've always wondered about those "send text to ###" commercials I see on TV and how shocked many parents must be when they receive huge bills for for some useless service that their kids racked up.

Call any provider and ask them. Enter into no agreement if they won’t offer a plan that gives you cost-certainty.
