I just signed up as a new customer with two 4Ss on Verizon. When I signed up it didn't give me the option of selecting different data plans for each phone. 5 GB on one automatically signed me up for 5 GB on the other. Is this something I'll be able to change, or do all data plans on Verizon's family plans have to be the same? I don't *think* it was shared data. Thanks.
