I purchased the unlimited data plan when I first got my car, hotspot is on, uconnect
 

Ok, gotcha. So it sounds like it's on and activated, but your unable to use it? I've not used this feature, but I've heard it is similar to connecting to a wifi router. Are you able to see anything called Uconnect or something similar while searching for a wifi signal in your phone?

If there is a problem, I suspect you would need to contact Uconnect directly. This excerpt was copied from their site:

I've dealt with Uconnect customer service in the past on a couple of vehicles. To say it bluntly, they are not very helpful. They read from a script which is fine, and normal for a call center. But it usually takes multiple calls to get the problem fixed. Mostly because they've hang up on me a few times because they don't know how to forward a call.

I hope you get it sorted out before having to call them, and if you do, I really hope you don't have the same experience with them.
