I can't renew cellular data on ipad mini
I have an ipad mini 2, model MF083LL/A.
I went to reactivate my cellular data plan just now and when I go into my cellular data account, it says "Invalid Access. Please close the page and reopen View Account. (USIM9991). "
I have done this over and over again for a good dozen times and get the same reply. What is this all about and what can I do to correct this?
Thanks, Martha
