new iPad Air 2, iOS 9.0.1. Unlocked. Bought straight Talk BYOT sim and data card. Installed following directions to the letter including downloading and installing cellular profile. Keep getting not activated messages. Look up account on ST and it says device is ACTIVATED. But I have no cellular data connection to Internet. called ST, talked in circles, wanted me to update my APN settings, but after the installations there is no place to make these changes. Seems there ought to be an app that does that for you or at least guides you. The ST people have no clue. Looks like I wasted my money on this SIM card and the data card. A few more calls to them letting them talk in circles about changing the APN Settings that can't be found and they will have spent more than I paid. I'll call it even then. I have a ST phone that is great, inexpensive, and relatively anonymous. Pay cash phone and for prepaid cards never register with a name, sure they can find info other ways, but, it's not like it was gift wrapped. Edit: What I was trying to get across is they kept asking me to go to the "Cellular Data Menu" which was no where to be found and they didn't know and couldn't tell me how to get there. Does anyone have any suggestions for getting my iPad online via ST? Other than wifi or tethering?
