Firt off, the people I blocked on his phone are bad influences, so do not call me a bad parent for looking out for my son.

I blocked my son's phone so he couldn't call/text certain people, and I tested it to see if it worked (it did), but his phone gets a text afterwards and says, "the phone owner has blocked this phone number", or something like that. I want to know how I can stop Verizon from sending these messages to his phone, or he will know that I blocked them.

Thank you.
