Hi I bought an open box 4g IPad and I never signed up for data or anything. I tried going on it to activate a data plan but it gives me a note that says I can't access account because it's already activated and can't be accessed on the ipad. However, I see the 4G cell data active and the internet works even with my Wi-Fi off. So I dont really know what to do. I've never owed an ipad that had an internet plan. The gist of it is that I'm currently getting free data, but would rather not worry about any repercussions and would like to do the right thing. Additionally I don't know if should visit Verizon or Apple about it. Any thoughts and help is appreciated. Thank you.
