The corporate policy of AT&T is to prevent you from using the data you purchase. I have the 3GB plan on my iPhone 6. AT&T dictates that I may not have a "hot spot" to share those 3GB's I have already paid for in the manner that I specify. I want to use my data on my other wireless devices. Their answer is: pay us $20 more per month plus taxes and additional fees and we will let you share your data with other devices. Boo, hiss! This is a terrible policy. I cannot recommend AT&T.
