Don' t press # 90 or #09

[Alaska]

If you receive a phone call on your mobile from any person, saying that,
that they're checking your mobileline, and you have to press # 90 or #09
or any other number. End this call immediately without pressing any
numbers.

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 you can, to stop it.
