Getting a message that says I have no data availible, but I already purchased pre-paid data.
I purchased a Netgear LB1120 modem and a pre-paid AT&T SIM card. I have already purchased the 8gb plan. I have logged in to verify that I have data. When I try to go to the wifi I get a message from AT&T saying "It looks like you want to use data but have none available. You may need to add a data package or change to a plan that supports data for your device."
I have already checked my plan, I should have data. I've tried restarting it and nothing seems to work. Help.
