Every now and than, I would get a warning,( when using the maps app) that says, "There is no data remaining on your current plan. Would you like to add more data now? If you don't add now, you can do it later in settings.". This is odd, because the iPad is part of my plan. Because of this warning, my maps app would no longer work. I would have to go into settings, turn it on and off airplane mode, resetting the network connection. This happens enough for me to notice but, not a everyday thing. Verizon says, this is a, Apple thing. I would like to ask, what do you think may be the cause of this, and how would you be able to stop it?
