There are phone scams elsewhere but it seems not to the same extent. In the UK we no longer have a nationalised phone service but the regulatory environment seems to be more successful in keeping the worst excesses under control.
I sometimes get calls from automated systems but they show up as International on the caller ID. I believe that the regulations for automated call systems are stricter and enforcement harsher here so they only operate from outside the UK jurisdiction. We also get free caller-id if you know how to sign up for it.
Calls to mobiles are charged entirely to the caller here and mobile numbers have a standard prefix anyway so we do not have two of the elements of the problem.
I did get some random cold calls on my mobile a while ago claiming to be from my mobile phone company and trying to sell me a new contract. The problem with that was that my phone is pay-as-you-go so there is no contract to expire. I think they were just calling all numbers that were first registered 18 months earlier because that is the usual first contract duration.
The problem that gets the most coverage here is reverse charged SMS messages where people say they did not request the messages. That seems to have died down a bit now; I believe that was as a result of the regulator making the mobile phone companies get their act together in responding to complaints.
