No jury trial? No you cannot have a class action but you can do a single right of action through "Arbitration" or "Small Claims Court" or a "State Supreme Court" jury or non jury. Verizon only had jumped on the Class Action Suits not allowed after the US Supreme Court ruled in AT&T favor. But the court did not rule out "Class Actions" totally. There are presently three class actions in Federal Courts over that NSA issue. There may be more.
Verizon cannot outlaw lawsuits they wish they could but that will never happen.
