GSM Code for AT&T voicemail?

[apunkrockmonk]

Awhile back I changed my voicemail over to youmail's service.

While it's nice I'd like to go back to the factory AT&T voicemail.

I googled for hours, called 1-800 MY IPHONE and AT&T. No one could help.

When I asked AT&T they put me on hold for 5 minutes. Came back and asked if I forgot my vm password. I said no. I need the gsm code. That you type in the keypad that starts with *#. They put me on hold another 5 minutes. Said there is no number and reset my vm password.

So can anyone here be my savior and tell me the gsm code to change my phone back to AT&T voicemail. Or tell me the number for AT&T voicemail.

Answer found finally.

If you have this issue in the future dial #002# and hit send.

Should reset it back to the default and it will begin working again.

Couldn't you reset all settings?

I didn't try, I did try resetting network settings.

I don't think resetting all settings would've worked though.

The number is stored on the sim card, putting in #002# must either pull down the number from AT&T and reset it on the sim card, or the default is stored on the sim card and this just resets it.

But I don't believe that the reset all settings would've changed the conditional call forwarding setting like that gsm code did.
