Okay,I have a spoofcard. I have a cingular phone. I called my friend tonight using my spoofcard.She also has a cingular cell phone. When I called her with the spoofcard I made the phone number on her cell phone show up as her own number,example-her phone number is(not really) 555-5555 so I made 555-5555 show up.She did not answer her phone it went to voicemail which in turn asked me if I wanted to check her messages,of course I said yes and listened to her messages.I tried this again calling my husbands cingular phone and it did the same thing,I called another cingular cell phone and the same thing happened again,I was able to listen to the messages.Does this only happen if the person doesnt have a password on the voicemail? I wonder if this works with other cell carrier voicemail systems? Has anyone else tried or done this before? I know with cingular to check your voicemail you just dial your own cellphone number from your cell phone.
