link to +44-79 numbers. The 37 is listed to jersey telecom. All others fro 1-99 have other operators. Regular UK operators. So I don't see why the 37 would be a special number as 79 is also the starting code for many other mobile phone providers.
From all I have heard till now rates calling 7937 are the same as calling to any 79xx number.
