I'm sure this has been discussed in other threads, but I was wondering if someone could explain this to me. I'm about to purchase the Bionic bundle on Costco's website and want to grandfather my unlimited data plan. I've tried to call Costco's main customer service number, but they said they couldn't help me with Wireless Center purchases.
Any advice from those who have done this? How does the grandfathering work?
Thanks in advance!
