TPS isnt a BT service!
@Graham T - The TPS scheme is not and never has been a BT service, - BT link to it but it is in fact run by the Direct Marketing Assocation. BT do little or nothing to help its hapless customers avoid intrusive calls from various sales operations EVEN WHEN TPS registered, unless of course you count the premium charged anonynous call rejection service which really should be available as part of the select services package. In fact even when companies abroad try to circumvent the system by spoofing UK geographic numbers, BT claim to be powerless to intervene. Apparently it is beyond the wit of thier network software people to create an routine that queries incoming calls to ensure they are coming from an authentic UK area code/ number
As for how wonderful the US cell phone charging system is, this is the same system that robs pay as you go customers of any credit remaining whe it is time to "top up" while blocking their phone even to incoming calls as happens on a friends PAYG cell in Iowa? As a UK PAYG customer, I prefer our system, I accept that I should pay the full cost of making a call that I decide to make, and would probably use my phone less if I knew my friends had to pay some of the cost of my calling them. and of course any credit remaining on my top up date remains mine to use.
