I have an unlimited data plan for under $30 on my iPad. No limits! (And no longer available to others, but I'm happy.)
I analyzed my data usage and found I never got anywhere near needing that and gave up the unlimited $30 plan in exchange for adding my iPad to my originally 10GB shared family plan for only $10. Now that's gone unlimited and still just $10 added to the shared plan. . . much cheaper than $30 Per month plus taxes. So I now have 3 iPhones and 2 iPads on a shared family plan. . . and they kept lowering the cost and upping the limits over three months from when I first switched. Ain't competition wunnerful?
I have the unlimited plan from ATT on mu iPad too.
That’s because I bought the iPad one on the first day they went on sale. I stood in line and bought my iPad and then a day or two later AT&T cancelled the plan.
I just bought the new iPad Air and was able to transfer my unlimited plan over to the new one. :)
