Beware of such fake calls.....

If you receive a phone call on your Mobile from any person saying that they
are checking your mobile line, and you have to press #90 or #09 or any
other number. End this call immediately without pressing any numbers.
Friends there is a fraud company using a device that once you press #90 or
#09 they can access your SIM card and make calls at your expense. Forward
this message to as many friends as u can, to stop it. This information has
been confirmed by both Motorola and Nokia. There are over 3 million
affected mobile phones. You can check this news at CNN web site also.
