A typical case of this scam is a one where someone opens a
premium rate number at local telecom operator and starts sending
SMS messages to random mobile phone numbers. A typical message
contains some urgent message and instructions to call the number
listed in the message.
If a person calls this number he will be connected to premium
rate number which will contain recording intended to keep the
user on the phone as long as possible. As the number where the
user called is a premium rate number, he or she will pay for each
minute spent connected to that number.
If you get an SMS message asking for you to call unknown number,
either ignore the message, or if you are interested use the
operators directory service to find out to whom that extension
belongs. But do not call the number directly.
If you get email warning about such scam, please ignore the email
and do not pass it on. If you want verification about the
warning, please contact your local telecom operator.
-UK June-July 2001
Scamsters sent SMS messages to random people containg following
message 'Please call me on 09011 500065 Urgent"' If a person
called this number he will be connected to premium rate which
played busy tone to fool the caller that the line was busy. The
number charged £1.50 per call.
This case is no longer a threat since the extension in question
has been closed.
