The network was unable to carry packet data, so users were unable to access the Internet, and services like MMS were not possible. The operator has not yet provided an explanation for what caused the data network to crash.
This really doesn't look good for O2, which may be about to lose its iPhone exclusivity to T-Mobile (UK) and Orange UK , according to this Mobile Today report.
UPDATE -- An O2 spokesperson sent this statement to Unstrung early this afternoon:
- We have identified the cause of the fault, which relates to the allocation of IP (Internet Protocol) addresses needed to establish a data connection. We have managed to restore data services to the vast majority of customers and are doing everything we can to ensure the few remaining customers are back online as soon as possible.
