Roaming

I do think revealing that a call on a UK registered mobile is being made from outside UK has privacy ramifications where there are apparently no compelling grounds for such display. Therefore, a mobile operator that indirectly discloses that an individual subscriber's mobile is being used outside the UK is likely to disclose personal data outside the expectation of the individual concerned. This may well involve the unfair processing of personal data.
