> A Freedom of Information request to get the full list,

Although (as far as I know) the FOI Act only applied to public bodies (government and organisations like universities). So O2 wouldn't need to comply with a request under that act. Not sure if the ICO could force them to disclose that info, but I doubt it.

That is correct. You can issue Subject Access Request under the Data Protection Act to find out information about an individual (yourself) and who this has been shared to. You can only issue a SAR in writing and there is a capped charge for £10 for the privilege.
