Getting spam texts and calls in the dozens upon dozens a day since switching to Verizon.

Switched to Verizon Simplicity plan from T-Mobile. And since I brought my own phone as the plan encourages in order to get a better price, they don't allow me to install the spam blocker stuff. And holy crap baby jesus on a rocket the amount of spam texts i get now plus spam calls has increased 100 fold. There is not a day where I don't get dozens of random spam texts when I would maybe get one a month at T-Mobile. Several calls a day when such calls would just get auto blocked previously. What folks with Verizon plans that are using phones not locked to Verizon doing to get this spam stuff under control? Looking for recommendations.
