Go into the messages app and select the voicemail portion. Long press your voicemail number and add a comma after the number then your password.

Example: *86,0000

 

Setting>Call>Voicemail Settings>Voicemall number, then after your full phone number, you can add in your pin by adding P, then your pin #, followed by the ound sign.

So your voicemail number should read (with using 212 as the area code & a generic #'s as my #) "12121234567p1234#"
