Welcome to the all-new iMore Forums! - We're still moving some things around, so you may see a few quirks here and there, but we're working on getting things fully completed as soon as possible. For now, take a look around, and if you run into any major issues, please let us know in this thread!
I'm grandfathered in with unlimited also but rarely go over 2 gig. I'm on wifi at home and at work all day so rarely use just lte. Even though the lte is usually faster than my wifi!
