Need Voice Mail Access # for 510-207-XXXX cell#

I need a voice mail access number for a 510-207-XXXX Cingular cell number. That is a phone number, other than my cell number, that I can call from any phone, to check my voice mail. Anyone have it?

Thanks.

Delete the number you have entered for your voice mail number, turn off your phone and remove your SIM card. Reinsert the SIM card and turn the phone back on. The voice mail number assigned to that wireless number should be updated from the SIM card. A number manually entered prevents the update from the SIM card.

If you have not made any changes to your phone's settings, the correct voice mail retrieval number should already be programmed into the phone. In that case, you can find the number in call history.
