Which is what I said...unlimited goes bye bye when you upgrade. If on tiered, you can keep your current plan. If you are upgrading a non-smartphone is the question here. When you upgrade to a smartphone, it puts you on a new plan. I'm not sure you can avoid the share in that case.
If I upgrade the feature phone to a smart phone I will not be forced into a share plan. They have said that. I will simply be adding a feature to that line (a tiered data plan). Its not changing my plan or anything else, and I can remove it by reactivating a feature phone on that line. I don't know why everyone believes that they are going to be forced onto the new share everything plans, or that the Share everything plans are going to be the only ones available. Verizon has said that they would not force people onto them, and the CS reps on their twitter feed and FB page said that the old plans will still be available. If you have facts that show if you upgrade after the 28th you will be forced into a share plan please show them.
