caller ID blocking (sent to http://www.credomobile.com/~customerservice)

[http://www.sneakemail.com/~bccme]

Dear Credo,

I thought that I had caller ID blocking on my cell phone, but, when I called a number just now, the number was revealed.

Could you please double-check to make sure I have caller ID blocking?

My cell phone number is our-Oakland-cell-phone-number.

Thanks.
