This service has however been reported as having "significant scamming activity" of various sorts[1][2] as users can mistakenly assume they are calling a UK mobile telephone number that generally costs far less.
[3] In the United States, AT&T ran a trial in 1991[4] which led, in 1992, to the AT&T EasyReach 700 service[5][6][7] of follow me numbers, on area code 700.
[15] Concerned at the number of scams, Ofcom consulted on removing revenue share from the 070 range and this took effect in 2009.
They had previously considered other options such as moving this service to the unused 06 number range or enforcing a pre-call announcement of the call charges.
[17] Those changes took effect on 1 October 2019[18] and several phone providers have already passed the saving on by now including calls to 070 numbers within inclusive allowances[citation needed].
