I would like to store my voicemail password on Windows Phone 8. Is this possible?
YESSS!!! IT IS POSSIBLE. here is my simple cheat for the voicemail p/w dilemma on my WP8... Without creating a contact in your phone book. The commas wouldn't save for me after trying the above. So I used a lower case letter p. AND yes I know WP8 limits the input in the phone settings area SO- The trick is to type it into a text anywhere else-
For example - *86pp1234567 (you can use either one or two p's)
Then highlight and copy it.
Then go back to the settings and paste it in place of the default voicemail #.
In theory you should be able to save your VM pin in the Dialer settings. There is an option to turn OFF the default voicemail number and enter in your own. (For Verizon you would enter *86,0000# where 0000 is your pin, the comma can be accessed by pressing and holding down the "." key)
This worked on my WP7 phone (HTC Trophy) and I've tried several times on my HTC Windows 8X but continue to recieve an error message ("We're having trouble saving your voicemail number right now. Please try again later"). Don't know if it's a Verizon, Microsoft or HTC issue and have been unable to find anything about it on the web.
This appears to be a permanent limitation/feature of WP8. According to a Microsoft MVP, overriding the VoiceMail number to include your PIN is a security issue.
The system doesn't let you intentionally override security for voicemail. You can do this for numbers stored in your normal contact list, but you can't concatenate your password to the voicemail number.
You would first need to know your Voicemail number. You can go to the website of your carrier, or simply call.
Then, you would need to use the copy/paste method used on Cellenbow's answer.
Type the number in a normal text box, then highlight and copy, go to the Voicemail input box. And paste.
You would need to use either , (comma) or p (pause). Comma can be accessible from the . (Dot) key in the Voicemail, hold on the dot key, then you can choose the comma.
You might need one or two commas or pauses. It depends on how your voicemail carrier settings. I would recommend calling voicemail, and having a stopwatch or anything similar, and count how many seconds are there from the time your call get answered, untill they require you for PIN entry. And every comma/pause is worth 3-5. So you might need to count for that. But don't use too many, because then your call will be dropped for timeout.
Also, some carriers will require you to enter your PIN then press the # (pound) key. If that is the case, then you will need to include that.
Think of it as if you are telling the phone what to enter in the keypad when u call someone, they created this method so you can store phone numbers with extensions to be autodialed.
Finally, WP8.1 might be just fine with entering the comma and the PIN right away, and it will save it without any issues. (I have tested it)
I know this question was asked a long while ago, but I hope this was helpful and brief. (It is self-explanatory)
