Hey guys I'm on a family plan and currently grandfathered into the unlimited $30 4G plan. One of the other lines that currently not a smartphone is coming up for an upgrade soon. In the past I've been able to get the subsidized price for a new smartphone by renewing the dumbphone line a smartphone and then removing the data plan. Would it be possible to do so with Verizon's current plans? I don't want to lose my unlimited data... Thanks in advance!
