I have four phones. A & B are smartphones w/ grandfathered unlimited data. C & D are feature phones. The users of C&D would like to move to smart phones. According to the VZW CSR I just chatted with they cannot move to smartphones on the same account. I'm not convinced that's correct (can't they get the $30/2gb plan?) but I don't mind moving them to a different account. My current bill is for 1400 minutes voice, unlimited data x2, 2 extra lines, and 2 lines of unlimited texting. Can I drop the two extra lines & their texting and downgrade to 700 minutes voice without affecting the unlimited data?
