Generically speaking, mobile operators sometimes exchange roaming agreements amongst themselves, when this happens they have to deny access in their own networks due to the subscriber then appearing to them as a local subscriber, which they don't have any record of, on the other hand the same subscriber gains access to many countries that would not make commercial sense for their operator to do direct agreements with.
