I have several smartphones that I am thinking of moving to a mobile share plan + 10 GB of data/month.

I'm assuming that I could also add an ipad for 10/month and use the ipad as a mobile hotspot, but I can't find anything that says this (they only talk about "smartphones" or say that you can use Mobile Hotspot with Mobile Share, but don't specifically say tablets). 

Can anyone tell me if this is correct or not?
