Safari cannot connect to the Internet, not subscribed to a cellular data service

My phone will not let me browse the Internet - i get the above message???

To add I've swapped my sim into non iPhones and back again with no issues connecting to o2's data connection. 

Perhaps a question for @Toby  @Anonymous 

Do both Contract Customers and Payg need to be placed on iData settings on their accounts -> is their even such a setting on a customers account or does O2 detect what type of phone is being used and auto adjust ?

[MI5]

There were many new iPhone 6 owners that were on the wrong data settings and had to call to get data changed to iData, so if it is automatic it doesn't always work.
Also, iData settings will work in a different (non iPhone) phone, whereas standard data will not work in an iPhone unless you change the apn to "mobile.o2.co.uk" and then you lose the iPhone specific features such as VVM etc.

Here is my thread with official clarification on iData.
