Phonepayplus knows 60999
These are revenue share short codes. All the Regulator has to do is 'follow the money' to discover who is behind this fraud.
Ofcom allocated the short code block 60000 - 60999 to Orange. The short code 60999 was given to txtNation.
txtNation uses it to run numerous campaigns on behalf of their clients.
Phonepayplus should ask them.
