Last year around November/December I signed up for a promo they were offering for data plans. Basically (if on a family share plan) you had to put all lines on a $29.99 data plan, then Verizon issued a $20 credit for each of those lines. So basically every line on the plan got unlimited data for $9.99 each. It was a great deal and they ended it quickly. I recently called in to find out about a few things with the new tiered data structure. What I found was: 1. Even though I had unlimited data on every line, 2 lines still had feature phones on them. When they upgrade next they will fall under the tiered data structure. Apparently to qualify to be grandfathered into unlimited data, the line had to have a smartphone on it, not just unlimited data. 2. The ability to upgrade & keep unlimited will last for at least another upgrade and will not be afftected if you're switching from 3G to 4G. But beyond that they were unclear on how long we'd be able to keep unlimited data. 3. This is the reason I started this thread. Anyone who got into the data promo I described previously will keep that discount through...2038 according to their records. While the others were kind of a bummer, this made my day. Now granted, they will probably come up with a way to get people to relinquish this discount (some new feature that will require losing this discount), but maybe not. If you got in on it, try and hold onto it!
