I've been with Verizon forever and still have the unlimited data plan. I believe I've been able to get the unlimited data plan because I do all of my upgrading through Costco. The reps at Costco work the systems to make sure that my plan doesn't change. Now I'm concerned that I may have to change my data plan now that my wife FINALLY decided she wants a smartphone. I hope the guys at Costco can work their magic...at the very least keep the unlimited data with my line since my wife most likely will stay within her data limits.
