Throttling on unlimited


Is Verizon getting worse about throttling on the unlimited plan regardless of how much data you've used?   I really refuse to move to "beyond" unlimited as unlimited should be usable, yet my kids are complaining..  text messages aren't going thru..and I'm unable to track their location for after school pick up.

$200 a month for 2 lines using under 15G a piece.   Thoughts?
