Unable to connect to Orange cellular network with new iPad 4G
I recently traded in my iPad 2 for the new model and decided to buy one with 4G capability for when I am out of a wi-fi area. Bought my Orange micro SIM, activated it and checked that cellular network settings were correct. My iPad works beautifully on wi-fi, but when I try to connect to Safari or my mail using Orange, I get an error message saying it cannot connect to cellular network, despite the fact that I have 3 or 4 bars showing. My iPhone connects to Orange with no problem.
So far, I have reset network settings, double checked my cellular data settings and tried turning cellular network and the iPad off and on. Everything seems fine with the SIM.
Bearing in mind that this is my first time using cellular network on an iPad, could anyone give me an idea of what to try next?
