I am in the exact same situation as you. I received my iPhone 6 on Friday and I have been able to use data for a total of one day and that's it. Every web page I try to load comes back with the following error -
"We're sorry, but you are attempting this transaction during a restricted time period set by your wireless account owner."
I am the account owner and I have no reason to restrict myself from anything. I have spent a few hours with Apple and AT&T. I have been assisted by Tech Support, Level 2 Tech Support, Network team and Product Management with AT&T. One person Saturday told me that everything was okay on the account yet one representative said they saw a block similar to SmartLimits. Worst part is that the feature SmartLimits no longer even exists. They do not know what the issue is. They are opening up a case and ticket to try and resolve it. I am expecting a few phone call tomorrow afternoon.
Whew!! I thought I was the only one out there with this issue and started feeling crazy.
