I bought a nexus tablet 2013 LTE version unlocked. I Bought a att Sim card, but when I am taken to the att website to purchase a data plan it does not recognize the nexus as a tablet and thus the att website only offers me a data plan for laptops and not tablets. Note I have tried multiple att Sim cards with the same results. If I try the Sim card on my old iPad the Sim card works as when it takes me to the att website I am offered tablet plans.
I emailed nexus support, but they could not provide a resolution.
